MATERIAL SAFETY DATA SHEETS (MSDS)

REQUIREMENT LETTER HAZARD COMMUNICATION STANDARD

Effective March 17, 1989, all employers, including Construction Contractors, will be covered by OSHA’s Hazard Communications Standard. The Standard has been in effect since 1986, but previously covered only the manufacturing industry. The purpose of the Standard is to ensure that the hazards of all chemicals used in the workplace or at a work site are evaluated and that this information is transmitted to affected employees. Every prime contractor, subcontractor, or any other contractor with one or more employees is covered by the Standard. The term “hazardous chemical” refers to any chemical which could affect an employee’s health with affects ranging from mild irritation to highly carcinogenic. Examples would be asbestos and asbestos containing materials, paints and varnishes, welding materials, cements, compressed gasses, and silica sand used for sandblasting. If employees are potentially exposed to hazardous chemicals, the employer is required to develop a written hazardous communication program including the following:

1. A Material Safety Data Sheet (MSDS) for each known hazardous chemical used by the contractor, and container labeling or other forms of warning.

2. A written plan must be developed outlining the method that will be used to inform employers, workers, and other contractors of hazardous chemicals they may be exposed to while working at a joint worksheet.

3. An employee training program which explains the hazardous chemicals in their work area at the time of initial assignment and wherever a new hazard is introduced into their work area.

Contractors will be required to make the written hazard communication program available upon request to employees or their designated representatives and officials of the Industrial Commission, Division of Occupational Safety and Health. The Standard requires an employer to identify each hazardous chemical container with a label, tag, or other mark clearly identifying the material. All warning labels shall be in English and clearly legible. An employer may voluntarily include the warning in other languages, but to comply with the law, it must also be in English. An employer may use signs, placards, process sheets, batch tickets, operating procedures, or other written material in lieu of individual container labels, as long as this method identifies the containers to which it applies and conveys the necessary labeling information. These materials must be readily available to employees. A Material Safety Data Sheet (MSDS) is required to be provided to an employer by the chemical manufacturer, importer, or distributor with the initial purchase of a hazardous chemical and with any subsequent purchase after a MSDS has been updated. The MSDS for each chemical being used by a contractor’s employees must include the following and be written in English:

A. The chemical and common name of individual hazardous substances.

Page 1 of 1

of 2

B. The chemical and common names of any health hazardous ingredient exceeding 1% in a mixture.

C. The chemical and common name of all ingredients which are a physical hazard when present, including vapor pressure, flash point, fire and explosion potential and reactivity.

D. Exposure signs and symptoms of health hazardous chemicals and the route(s) of entry.

E. OSHA’s permissable exposure limits. F. All known safe handling precautions. G. The known work practices, personal protection equipment, and engineering controls

to handle the hazardous chemicals. H. Emergency and first aid procedures. I. Preparation dates of the MSDS as well as dates of changes or additions. J. Name, address, and phone numbers of the company or person who prepared the

MSDS. The employee information and training program must include at least the following:

A. An explanation of the Standard governing hazard communications. B. The location and availability of the written hazard communication program and

MSDS C. The method and observations used to detect the presence or release of hazardous

chemicals in the work area. D. The measures the employee can use to protect himself from the hazards.

Contractors operating at work sites in Arizona and New Mexico are subject to unannounced inspections by compliance officers of the State OSHA. If, upon the first inspection, a contractor or firm is not in compliance with the Hazardous Communication Standard, it will be considered a VIOLATION of the Standard and may carry a penalty of up to $1,000 PER VIOLATION. Ordinarily, the contractor will be allowed between 15 and 30 days to correct the violation(s). If the violation(s) is (are) not corrected or there is a refusal to correct the violation(s), then penalties could be as high as $10,000 PER VIOLATION. The summary of the Hazard Communication Standard covers the highlights and is not intended to be all inclusive or a legal interpretation.

Skin: Contact with the skin causes irritation. Skin contact may cause drying or defatting of the skin. Symptoms may include pain, itching, discoloration, swelling, and blistering. Contact with the skin is not expected to cause an allergic skin response. Not expected to be harmful to internal organs if absorbed through the skin. Ingestion: Because of its low viscosity, this material can directly enter the lungs, if swallowed, or if subsequently vomited. Once in the lungs it is very difficult to remove and can cause severe injury or death. May be irritating to mouth, throat, and stomach. Symptoms may include pain, nausea, vomiting, and diarrhea. Inhalation: Mists of this material may cause respiratory irritation. Symptoms of respiratory irritation may include coughing and difficulty breathing. Breathing this material at concentrations above the recommended exposure limits may cause central nervous system effects. Central nervous system effects may include headache, dizziness, nausea, vomiting, weakness, loss of coordination, blurred vision, drowsiness, confusion, or disorientation. At extreme exposures, central nervous system effects may include respiratory depression, tremors or convulsions, loss of consciousness, coma or death. DELAYED OR OTHER HEALTH EFFECTS: Cancer: Prolonged or repeated exposure to this material may cause cancer. Whole diesel engine exhaust has been classified as a Group 2A carcinogen (probably carcinogenic to humans) by the International Agency for Research on Cancer (IARC). Diesel exhaust particulate has been classified as reasonably anticipated to be a human carcinogen in the National Toxicology Program's Ninth Report on Carcinogens. The National Institute of Occupational Safety and Health (NIOSH) has recommended that whole diesel exhaust be regarded as potentially causing cancer. Diesel engine exhaust is known to the State of California to cause cancer. Contains naphthalene, which has been classified as a Group 2B carcinogen (possibly carcinogenic to humans) by the International Agency for Research on Cancer (IARC). See Section 11 for additional information. Risk depends on duration and level of exposure. SECTION 4 FIRST AID MEASURES

Eye: No specific first aid measures are required. As a precaution, remove contact lenses, if worn, and flush eyes with water. Skin: Wash skin with water immediately and remove contaminated clothing and shoes. Get medical attention if any symptoms develop. To remove the material from skin, use soap and water. Discard contaminated clothing and shoes or thoroughly clean before reuse. Ingestion: If swallowed, get immediate medical attention. Do not induce vomiting. Never give anything by mouth to an unconscious person. Inhalation: Move the exposed person to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention if breathing difficulties continue. Note to Physicians: Ingestion of this product or subsequent vomiting may result in aspiration of light hydrocarbon liquid, which may cause pneumonitis. SECTION 5 FIRE FIGHTING MEASURES

_____________________________________________________________________

See Section 7 for proper handling and storage.



FIRE CLASSIFICATION: OSHA Classification (29 CFR 1910.1200): Combustible liquid. NFPA RATINGS: Health: 0 Flammability: 2 Reactivity: 0 FLAMMABLE PROPERTIES: Flashpoint: (Pensky-Martens Closed Cup) 52 °C (125 °F) (Min) Autoignition: 257 °C (494 °F) Flammability (Explosive) Limits (% by volume in air): Lower: 0.6 Upper: 4.7 EXTINGUISHING MEDIA: Use water fog, foam, dry chemical or carbon dioxide (CO2) to extinguish flames. PROTECTION OF FIRE FIGHTERS: Fire Fighting Instructions: For fires involving this material, do not enter any enclosed or confined fire space without proper protective equipment, including self-contained breathing apparatus. Combustion Products: Highly dependent on combustion conditions. A complex mixture of airborne solids, liquids, and gases including carbon monoxide, carbon dioxide, and unidentified organic compounds will be evolved when this material undergoes combustion. SECTION 6 ACCIDENTAL RELEASE MEASURES

Protective Measures: Eliminate all sources of ignition in the vicinity of the spill or released vapor. If this material is released into the work area, evacuate the area immediately. Monitor area with combustible gas indicator. Spill Management: Stop the source of the release if you can do it without risk. Contain release to prevent further contamination of soil, surface water or groundwater. Clean up spill as soon as possible, observing precautions in Exposure Controls/Personal Protection. Use appropriate techniques such as applying non-combustible absorbent materials or pumping. All equipment used when handling the product must be grounded. A vapor suppressing foam may be used to reduce vapors. Use clean non-sparking tools to collect absorbed material. Where feasible and appropriate, remove contaminated soil. Place contaminated materials in disposable containers and dispose of in a manner consistent with applicable regulations. Reporting: Report spills to local authorities and/or the U.S. Coast Guard's National Response Center at (800) 424-8802 as appropriate or required. SECTION 7 HANDLING AND STORAGE

Precautionary Measures: Liquid evaporates and forms vapor (fumes) which can catch fire and burn with explosive force. Invisible vapor spreads easily and can be set on fire by many sources such as pilot lights, welding equipment, and electrical motors and switches. Fire hazard is greater as liquid temperature rises above 29C (85F). Do not get in eyes, on skin, or on clothing. Do not taste or swallow. Do not breathe vapor or fumes. Do not breathe mist. Wash thoroughly after handling. Keep out of the reach of children. Unusual Handling Hazards: WARNING! Do not use as portable heater or appliance fuel. Toxic fumes may accumulate and cause death. General Handling Information: Avoid contaminating soil or releasing this material into sewage and drainage systems and bodies of water.

_____________________________________________________________________

Static Hazard: Electrostatic charge may accumulate and create a hazardous condition when handling this material. To minimize this hazard, bonding and grounding may be necessary but may not, by themselves, be sufficient. Review all operations which have the potential of generating and accumulating an electrostatic charge and/or a flammable atmosphere (including tank and container filling, splash filling, tank cleaning, sampling, gauging, switch loading, filtering, mixing, agitation, and vacuum truck operations)



and use appropriate mitigating procedures. For more information, refer to OSHA Standard 29 CFR 1910.106, 'Flammable and Combustible Liquids', National Fire Protection Association (NFPA 77, 'Recommended Practice on Static Electricity', and/or the American Petroleum Institute (API) Recommended Practice 2003, 'Protection Against Ignitions Arising Out of Static, Lightning, and Stray Currents'. General Storage Information: DO NOT USE OR STORE near heat, sparks, flames, or hot surfaces . USE AND STORE ONLY IN WELL VENTILATED AREA. Keep container closed when not in use. Container Warnings: Container is not designed to contain pressure. Do not use pressure to empty container or it may rupture with explosive force. Empty containers retain product residue (solid, liquid, and/or vapor) and can be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, static electricity, or other sources of ignition. They may explode and cause injury or death. Empty containers should be completely drained, properly closed, and promptly returned to a drum reconditioner or disposed of properly. SECTION 8 EXPOSURE CONTROLS/PERSONAL PROTECTION

GENERAL CONSIDERATIONS: Consider the potential hazards of this material (see Section 3), applicable exposure limits, job activities, and other substances in the work place when designing engineering controls and selecting personal protective equipment. If engineering controls or work practices are not adequate to prevent exposure to harmful levels of this material, the personal protective equipment listed below is recommended. The user should read and understand all instructions and limitations supplied with the equipment since protection is usually provided for a limited time or under certain circumstances. ENGINEERING CONTROLS: Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below the recommended exposure limits. PERSONAL PROTECTIVE EQUIPMENT Eye/Face Protection: No special eye protection is normally required. Where splashing is possible, wear safety glasses with side shields as a good safety practice. Skin Protection: Wear protective clothing to prevent skin contact. Selection of protective clothing may include gloves, apron, boots, and complete facial protection depending on operations conducted. Suggested materials for protective gloves include: Chlorinated Polyethylene (or Chlorosulfonated Polyethylene), Nitrile Rubber, Polyurethane, Viton. Respiratory Protection: Determine if airborne concentrations are below the recommended occupational exposure limits for jurisdiction of use. If airborne concentrations are above the acceptable limits, wear an approved respirator that provides adequate protection from this material, such as: Air-Purifying Respirator for Organic Vapors. When used as a fuel, this material can produce carbon monoxide in the exhaust. Determine if airborne concentrations are below the occupational exposure limit for carbon monoxide. If not, wear an approved positive-pressure air-supplying respirator. Use a positive pressure air-supplying respirator in circumstances where air-purifying respirators may not provide adequate protection.

Incompatibility With Other Materials: May react with strong acids or strong oxidizing agents, such as chlorates, nitrates, peroxides, etc. Hazardous Decomposition Products: None known (None expected) Hazardous Polymerization: Hazardous polymerization will not occur. SECTION 11 TOXICOLOGICAL INFORMATION

IMMEDIATE HEALTH EFFECTS Eye Irritation: The eye irritation hazard is based on evaluation of data for similar materials or product components. Skin Irritation: The skin irritation hazard is based on evaluation of data for similar materials or product components. Skin Sensitization: This material did not cause skin sensitization reactions in a Buehler guinea pig test. Acute Dermal Toxicity: LD50: >5ml/kg (rabbit). Acute Oral Toxicity: LD50: > 5 ml/kg (rat) Acute Inhalation Toxicity: 4 hour(s) LC50: > 5mg/l (rat). ADDITIONAL TOXICOLOGY INFORMATION: This product contains gas oils. CONCAWE (product dossier 95/107) has summarized current health, safety and environmental data available for a number of gas oils, typically hydrodesulfurized middle distillates, CAS 64742-80-9, straight-

_____________________________________________________________________



run middle distillates, CAS 64741-44-2, and/or light cat-cracked distillate CAS 64741-59-9. CARCINOGENICITY: All materials tested have caused the development of skin tumors in mice, but all featured severe skin irritation and sometimes a long latency period before tumors developed. Straight-run and cracked gas oil samples were studied to determine the influence of dermal irritation on the carcinogenic activity of middle distillates. At non-irritant doses the straight-run gas oil was not carcinogenic, but at irritant doses, weak activity was demonstrated. Cracked gas oils, when diluted with mineral oil, demonstrated carcinogenic activity irrespective of the occurrence of skin irritation. Gas oils were tested on male mice to study tumor initiating/promoting activity. The results demonstrated that while a straight-run gas oil sample was neither an initiator or promotor, a blend of straight-run and FCC stock was both a tumor initiator and a promoter. GENOTOXICITY: Hydrotreated & hydrodesulfurized gas oils range in activity from inactive to weakly positive in in-vitro bacterial mutagenicity assays. Mouse lymphoma assays on straight-run gas oils without subsequent hydrodesulphurization gave positive results in the presence of S9 metabolic activation. In-vivo bone marrow cytogenetics and sister chromatic exchange assay exhibited no activity for straight-run components with or without hydrodesulphurization. Thermally or catalytically cracked gas oils tested with in-vitro bacterial mutagenicity assays in the presence of S9 metabolic activation were shown to be mutagenic. In-vitro sister chromatic exchange assays on cracked gas oil gave equivocal results both with and without S9 metabolic activation. In-vivo bone marrow cytogenetics assay was inactive for two cracked gas oil samples. Three hydrocracked gas oils were tested with in-vitro bacterial mutagenicity assays with S9, and one of the three gave positive results. Twelve distillate fuel samples were tested with in-vitro bacterial mutagenicity assays & with S9 metabolic activation and showed negative to weakly positive results. In one series, activity was shown to be related to the PCA content of samples tested. Two in-vivo studies were also conducted. A mouse dominant lethal assay was negative for a sample of diesel fuel. In the other study, 9 samples of No 2 heating oil containing 50% cracked stocks caused a slight increase in the number of chromosomal aberrations in bone marrow cytogenetics assays. DEVELOPMENTAL TOXICITY: Diesel fuel vapor did not cause fetotoxic or teratogenic effects when pregnant rats were exposed on days 6-15 of pregnancy. Gas oils were applied to the skin of pregnant rats daily on days 0-19 of gestation. All but one (coker light gas oil) caused fetotoxicity (increased resorptions, reduced litter weight, reduced litter size) at dose levels that were also maternally toxic. This product contains naphthalene. GENERAL TOXICITY: Exposure to naphthalene has been reported to cause methemoglobinemia and/or hemolytic anemia, especially in humans deficient in the enzyme glucose-6-phosphate dehydrogenase. Laboratory animals given repeated oral doses of naphthalene have developed cataracts. REPRODUCTIVE TOXICITY AND BIRTH DEFECTS: Naphthalene did not cause birth defects when administered orally to rabbits, rats, and mice during pregnancy, but slightly reduced litter size in mice at dose levels that were lethal to the pregnant females. Naphthalene has been reported to cross the human placenta. GENETIC TOXICITY: Naphthalene caused chromosome aberrations and sister chromatid exchanges in Chinese hamster ovary cells, but was not a mutagen in several other in-vitro tests.CARCINOGENICITY: In a study conducted by the National Toxicology Program (NTP), mice exposed to 10 or 30 ppm of naphthalene by inhalation daily for two years had chronic inflammation of the nose and lungs and increased incidences of metaplasia in those tissues. The incidence of benign lung tumors (alveolar/bronchiolar adenomas) was significantly increased in the high-dose female group but not in the male groups. In another two-year inhalation study conducted by NTP, exposure of rats to 10, 30, and 60 ppm naphthalene caused increases in the incidences of a variety of nonneoplastic lesions in the nose. Increases in nasal tumors were seen in both sexes, including olfactory neuroblastomas in females at 60 ppm and adenomas of the respiratory epithelium in males at all exposure levels. The relevance of these effects to humans has not been established. No carcinogenic effect was reported in a 2-year feeding study in rats receiving naphthalene at 41 mg/kg/day. This product may contain significant amounts of Polynuclear Aromatic Hydrocarbons (PAH's) which have been shown to cause skin cancer after prolonged and frequent contact with the skin of test animals. Brief or intermittent skin contact with this product is not expected to have serious effects if it is washed from the skin. While skin cancer is unlikely to occur in human beings following use of this product, skin contact

and breathing, of mists, vapors or dusts should be reduced to a minimum. SECTION 12 ECOLOGICAL INFORMATION

ECOTOXICITY 96 hour(s) LC50: 21-210 mg/l (Salmo gairdneri) 48 hour(s) EC50: 20-210 mg/l (Daphnia magna) 72 hour(s) EC50: 2.6-25 mg/l (Raphidocellus subcapitata) This material is expected to be toxic to aquatic organisms. ENVIRONMENTAL FATE On release to the environment the lighter components of diesel fuel will generally evaporate but depending on local environmental conditions (temperature, wind, mixing or wave action, soil type, etc.) the remainder may become dispersed in the water column or absorbed to soil or sediment. Diesel fuel would not be expected to be readily biodegradable. In a modified Strum test (OECD method 301B) approximately 40% biodegradation was recorded over 28 days. However, it has been shown that most hydrocarbon components of diesel fuel are degraded in soil in the presence of oxygen. Under anaerobic conditions, such as in anoxic sediments, rates of biodegradation are negligible. SECTION 13 DISPOSAL CONSIDERATIONS

Use material for its intended purpose or recycle if possible. This material, if it must be discarded, may meet the criteria of a hazardous waste as defined by US EPA under RCRA (40 CFR 261) or other State and local regulations. Measurement of certain physical properties and analysis for regulated components may be necessary to make a correct determination. If this material is classified as a hazardous waste, federal law requires disposal at a licensed hazardous waste disposal facility.

Skin Contact: Wash with soap and water. If irritation develops and persists, get medical attention. Inhalation (Breathing): If irritation is experienced, move to fresh air. Get medical attention if irritation or other

symptoms develop and persist.

5 – Fire Fighting Measures

Extinguishing Media: Use water fog, dry chemical, carbon dioxide or foam. Do not use water jet or flooding amounts of water. Burning product will float on the surface and spread fire. Special Fire Fighting Procedures: Firefighters should always wear positive pressure self-contained breathing apparatus and full protective clothing. Cool fire-exposed containers with water. Use shielding to protect against bursting containers. Unusual Fire and Explosion Hazards: Contents under pressure. Keep away from ignition sources and open flames. Exposure of containers to extreme heat and flames can cause them to rupture often with violent force. Vapors are heavier than air and may travel along surfaces to remote ignition sources and flash back.

6 – Accidental Release Measures

Wear appropriate protective clothing (see Section 8). Eliminate all sources of ignition and ventilate area. Leaking cans should be placed in a plastic bag or open pail until the pressure has dissipated. Contain and collect liquid with an inert absorbent and place in a container for disposal. Clean spill area thoroughly. Report spills to authorities as required.

7 – Handling and Storage

Handling: Avoid contact with eyes. Avoid prolonged contact with skin. Avoid breathing vapors or aerosols. Use only with adequate ventilation. Keep away from heat, sparks, pilot lights, hot surfaces and open flames. Unplug electrical tools, motors and appliances before spraying or bringing the can near any source of electricity. Electricity can burn a hole in the can and cause contents to burst into flames. To avoid serious burn injury, do not let the can touch battery terminals, electrical connections on motors or appliances or any other source of electricity. Wash thoroughly with soap and water after handling. Keep containers closed when not in use. Keep out of the reach of children. Do not puncture, crush or incinerate containers, even when empty.

Storage: Store in a cool, well-ventilated area, away from incompatible materials Do not store above 120 F or

2. Hazardous Ingredients/Indentity Information (cont’d.)

Wood dust is now regulated by OSHA as “Particulates Not Otherwise Regulated” (PNOR), or Nuisance Dust. However, some states have incorporated the 1989 OSHA PELs in their state plans. Additionally, OSHA indicated that it may cite employers under the OSH Act general duty clause in appropriate circumstances for noncompliance with the 1989 PELs. B The VOC content of adhesives and sealants used are equal or less than the current VOC content limits of South Coast Air Quality Management District (SCAQMD) Rule #1168, AND all sealants used as fillers meet or exceed the requirements of the Bay Area Air Quality Management District Regulation 8, Rule 51. C These products may contain trace (<0.1%, wt %) amounts of free formaldehyde, which may be released depending on concentration and environmental conditions. These panels contain no urea-formaldehyde resins. Large scale chamber studies conducted by the APA Engineered Wood Association have shown that the finished products off gas levels below 0.1 ppm as well. D This ingredient is the polymerized form of MDI resin. There is no detectable MDI monomer in the product as purchased.

3. Hazard Identification

Appearance and Odor: TJI® Joist consists of a ligno cellulosic matrix of interlocking wood fibers having a slightly aromatic odor. The wood component of this product may consist of alder, aspen, beech, birch, cottonwood, fir, gum, hemlock, hickory, maple, oak, pecan, pine, poplar, spruce, walnut, and/or western red cedar.

Primary Health Hazards: The primary health hazard posed by this product is thought to be due to exposure to wood dust.

Primary Route(s) of Exposure: Ingestion: ⌧ Skin: Dust ⌧ Inhalation: Dust ⌧ Eyes: Dust

Medical Conditions Generally Aggravated by Exposure: Wood dust may aggravate pre-existing respiratory conditions or allergies.

Signs and Symptoms of Exposure: Acute Health Hazards: Wood dust can cause eye irritation. Certain species of wood dust can elicit

allergic contact dermatitis in sensitized individuals. Wood dust may cause respiratory irritation, nasal dryness, coughing, sneezing and wheezing as a result of inhalation. Formaldehyde may cause temporary irritation of skin, eyes, or respiratory system. Formaldehyde may cause sensitization in susceptible individuals. However, the potential is negligible for formaldehyde to off-gas from products made with phenol-formaldehyde resin.

Chronic Health Hazards: Wood dust, depending on the species, may cause allergic contact dermatitis and respiratory sensitization with prolonged, repetitive contact or exposure to elevated dust levels. Prolonged exposure to wood dust has been reported by some observers to be associated with nasal cancer. Formaldehyde is classified by OSHA and NTP as a probable or potential carcinogen. IARC has classified formaldehyde as carcinogenic to humans.

Carcinogenicity Listing:

NTP: Wood dust, Known Human Carcinogen. Formaldehyde, Reasonably Anticipated to be a Human Carcinogen.

IARC Monographs: Wood dust, Group 1 carcinogenic to humans. Formaldehyde, Group 1 carcinogenic to humans.

OSHA Regulated: Formaldehyde Gas


3. Hazard Identification (cont'd.)

NTP: (Wood Dust) According to its Tenth Report on Carcinogens, NTP states, “Wood dust is known to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in humans. An association between wood dust exposure and cancer of the nose has been observed in many case reports, cohort studies, and case-control studies that specifically addressed nasal cancer. Strong and consistent associations with cancer of the nasal cavities and paranasal sinuses were observed both in studies of people whose occupations are associated with wood dust exposure and in studies that directly estimated wood dust exposure.”

IARC – Group 1: (Wood dust) Carcinogenic to humans; sufficient evidence of carcinogenicity. This classification is primarily based on studies showing an association between occupational exposure to wood dust and adenocarcinoma of the nasal cavities and paranasal sinuses. IARC did not find sufficient evidence of an association between occupational exposure to wood dust and cancers of the oropharynx, hypopharynx, lung, lymphatic and hematopoietic systems, stomach, colon or rectum.

IARC – Group 1: (Formaldehyde) Carcinogenic to Humans. A working group of IARC has determined that there is sufficient evidence that formaldehyde causes nasopharyngeal cancer in humans, a rare cancer in developed countries. However, numerous epidemiological studies have failed to demonstrate a relationship between formaldehyde exposure and nasal cancer or pulmonary diseases such as emphysema or lung cancer. Rats exposed to 14 ppm of formaldehyde for 24 months in the laboratory developed nasal cancer. Exposure of 6 ppm did not result in statistically significant levels of nasal cancer.

4. Emergency and First-Aid Procedures

Ingestion: Not applicable under normal use. Eye Contact: Wood dust may cause mechanical irritation. Treat dust in eye as foreign object. Flush

with water to remove dust particle. Seek medical help if irritation persists. Skin Contact: Wood dust of certain species can elicit allergic contact dermatitis in sensitized individuals,

as well as mechanical irritation resulting in erythema and hives. Seek medical help if rash, irritation or dermatitis persists.

Skin Absorption: Not known to occur under normal use. Inhalation: Wood dust may cause unpleasant obstruction in the nasal passages, resulting in dryness of

nose, dry cough, sneezing and headaches. Remove to fresh air. Seek medical help if persistent irritation, severe coughing or breathing difficulty occurs

5. Fire and Explosion Data

Flash Point (Method Used): Flammable Limits: LFL = See below under “Unusual

Fire and Explosion Hazards” UFL = NAP

Extinguishing Media: Water, carbon dioxide, sand Autoignition Temperature: Variable [typically 400°-500°F (204°-260°C)] Special Firefighting Procedures: None Unusual Fire and Explosion Hazards: Depending on moisture content, and more importantly, particle

diameter, wood dust may explode in the presence of an ignition source. An airborne concentration of 40 grams (40,000 mg) of dust per cubic meter of air is often used as the LEL for wood dusts. Reference NFPA Standards- 654 and 664 for guidance.

HMIS Rating (Scale 0-4): Health = 2* Fire = 1 Physical Hazard = 0 NFPA Rating (Scale 0-4): Health = 1 Fire = 1 Reactivity = 0


6. Accidental Release Measures

Steps to be Taken In Case Material Is Released or Spilled: Not applicable for products in purchased form. Wood dust generated from sawing, sanding, drilling, or routing of these products may be vacuumed or shoveled for recovery or disposal. Avoid dusty conditions and provide good ventilation. Use NIOSH-approved respirator and goggles where ventilation is not possible and the allowable exposure limits may be exceeded.

7. Handling and Storage

Precautions to be Taken In Handling and Storage: No special handling precautions are required for products in purchased form. Avoid repeated or prolonged breathing of wood dust. These products may release very small quantities of formaldehyde in gaseous form. Under foreseeable conditions of use, these products release less than 0.10 ppm in standard large chamber test conditions. Store in well-ventilated, cool, dry place away from open flame.

8. Exposure Control Measures, Personal Protection

Personal Protective Equipment: RESPIRATORY PROTECTION – Not applicable for product in purchased form. A NIOSH-approved

filtering face piece respirator (“dust mask”) is recommended when exposure limits may be exceeded. EYE PROTECTION – Not applicable for product in purchased form. Goggles or safety glasses are

recommended when machining this product. PROTECTIVE GLOVES – Not required. However, cloth, canvas, or leather gloves are recommended to

11. Toxicological Information

Wood dust (softwood or hardwood)OSHA Hazard Rating = 3.3; moderately toxic with probable oral lethal dose to humans being 0.5-5 g/kg

(about 1 pound for a 70 kg or 150 pound person). Source: OSHA Regulated Hazardous Substances, Government Institutes, Inc., February 1990.

Wood dust – generated from sawing, sanding or machining the product – may cause nasal dryness, irritation, coughing and sinusitis. NTP and IARC classify wood dust as a human carcinogen (IARC Group 1). This classification is based primarily on increased risk in the occurrence of adenocarcinomas of the nasal cavities and paranasal sinuses associated with exposure to wood dust. The evaluation did not find sufficient evidence to associate cancers of the oropharynx, hypopharynx, lung, lymphatic and hematopoietic systems, stomach, colon or rectum with exposure to wood dust.

Formaldehyde OSHA Hazard Rating = 3 for local and systemic acute and chronic exposures; highly toxic. Irritation

studies: human skin, 150 ug/3 days, intermittent exposure produced mild results; human eye, 1 ppm/6 minutes produced mild results. Toxicity studies: human inhalation TCLo of 8 ppm reported, but response not specified; human inhalation TCLo of 17 mg/m3 for 30 minutes produced eye and pulmonary results; human inhalation TCLo of 300 ug/m3 produced nose and central nervous system results; LC50 (rat, inhalation) = 1,000 mg/m3, 30 minutes; LC50 (mice, inhalation) = 400 mg/m3, 2 hours. Source: OSHA Regulated Hazardous Substances, Government Institutes, Inc., February 1990; Registry of Toxic Effects of Chemical Substances (RTECS), National Institute for Occupational Safety and Health (provided by Canadian Centre for Occupational Health and Safety, CCINFO May 1995).

Exposure to gaseous formaldehyde may cause temporary irritation to the nose and throat as well as lead to respiratory disorders. However, in a thorough review of sensory/respiratory irritation studies of formaldehyde from the standpoint of occupational exposure, an expert panel has observed exposure up to concentrations of 0.3 ppm failed to produce irritation. With regard to respiratory disorders, studies have concluded the threshold for long-term chronic pulmonary effects is between 0.4 and 3 ppm and for chronic obstructive pulmonary disease is 2 ppm. Pre-existing respiratory disorders may be aggravated by exposure.


11. Toxicological Information (cont’d.)

Epidemiology studies of workers exposed to formaldehyde have failed to consistently identify an association between formaldehyde exposure and cancer. In animal studies, rats and mice exposed to high levels of formaldehyde developed nasal cancer while hamsters did not. These exposure levels are far above those levels normally found in the workplace. Formaldehyde is classified by IARC as carcinogenic to humans (Group 1). A working group of IARC has determined that there is sufficient evidence that formaldehyde causes nasopharyngeal cancer in humans, a rare cancer in developed countries. NTP included formaldehyde in the annual report on carcinogens. OSHA regulates formaldehyde as a potential carcinogen for exposures exceeding 0.5 ppm.

Target Organs: Eyes, skin, respiratory system.

Carcinogenicity Listing: NTP: Wood dust, Known Human Carcinogen. IARC Monographs: Wood dust, Group 1 - carcinogenic to humans. OSHA Regulated:

NTP: (Wood Dust) According to its Tenth Report on Carcinogens, NTP states, “Wood dust is known to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in humans. An association between wood dust exposure and cancer of the nose has been observed in many case reports, cohort studies, and case-control studies that specifically addressed nasal cancer. Strong and consistent associations with cancer of the nasal cavities and paranasal sinuses were observed both in studies of people whose occupations are associated with wood dust exposure and in studies that directly estimated wood dust exposure.” IARC – Group l: Carcinogenic to humans; sufficient evidence of carcinogenicity. This classification is primarily based on studies showing an association between occupational exposure to wood dust and adenocarcinoma to the nasal cavities and paranasal sinuses. IARC did not find sufficient evidence of an association between occupational exposure to wood dust and cancers of the oropharynx, hypopharynx, lung, lymphatic and hematopoietic systems, stomach, colon or rectum.

Section 5. Fire Fighting Measures

Flammable Properties

This product resist burning - Class A per ASTM E-84 (Flame Spread <25). Fire from a separate fuel source may be intense enough to cause thermal decomposition releasing toxic fumes and/or gasses. Wood dust is combustible, and may form explosive mixtures with air in the presence of an ignition source.

Extinguishing Media

Suitable Media: Water Fog, Foam, CO2, or Dry Chemical - Use methods for the surrounding fire.



Protection of Firefighters

Specific Hazards: Wood dust may present a strong to severe explosion hazard if dust cloud contacts an ignition source. Use water to wet down wood dust to reduce likelihood of ignition or dispersion of dust into air. Remove burned or wet dust to open area after fire is extinguished. Combustion or thermal decomposition can yield dangerous fumes of phosphorous compounds, nitrogen compounds, boron compounds, sodium compounds, carbon dioxide, carbon monoxide, aliphatic aldehydes, or polycyclic aromatic hydrocarbons. Protective Equipment and Precautions: Wear complete fire service protective equipment (Full Bunker Gear), including full-face NIOSH and NFPA – approved self-contained breathing apparatus (SCBA). Avoid inhaling any combustion products.

1 In AFL-CIO v. OSHA 965 F. 2d 962 (11th Cir. 1992), the court overturned OSHA’s 1989 Air Contaminants Rule, including the specific PELs for wood

dust that OSHA had established at that time. The 1989 PELs were: TWA 5 mg/m3; STEL (15 MIN) - 10 mg/m

3 (ALL SOFTWOODS AND

HARDWOODS, EXCEPT WESTERN RED CEDAR); WESTERN RED CEDAR: TWA - 2.5 mg/m3.

Wood dust is now officially regulated as an organic dust under the Particulates Not Otherwise Regulated (PNOR) or Inert or Nuisance Dust categories at PELs noted under the Hazardous Ingredients section of this MSDS. However, A NUMBER OF STATES HAVE INCORPORATED PROVISIONS OF THE 1989 STANDARD IN THEIR STATE PLANS. ADDITIONALLY, OSHA HAS ANNOUNCED THAT IT MAY CITE COMPANIES UNDER THE OSH ACT GENERAL DUTY CLAUSE UNDER APPROPRIATE CIRCUMSTANCES FOR NON-COMPLIANCE WITH THE 1989 PELs.

Engineering Controls

Use ventilation as necessary to keep exposure to airborne contaminants below the exposure limits. Due to the explosive potential of wood dust when suspended in air, ventilation systems should be kept clean and precautions should be taken to prevent sparks or other ignition sources.

Personal Protective Equipment (PPE)

Eye / Face Protection: When sawing, cutting, sanding, grinding, routing or chipping wood wear safety glasses with side shields. Skin Protection: When sawing, cutting, sanding, grinding, routing or chipping wood, wear clothing that covers the skin – long pants, long sleeve shirts, hat, gloves and shoes. When simply handling the product gloves should be worn to protect from splinters. Respiratory Protection: When sawing, cutting, sanding, grinding, routing or chipping wood, actions that can generate wood dust, a dust mask should be worn. General Hygiene Considerations: Wash thoroughly after handling and before eating, drinking, or smoking. Launder clothing worn when generating wood dust before reuse.

Section 11. Toxicological Information

No specific toxicological data is available on the fire retardant wood itself. However, considerable information is available regarding the toxicity of its components and untreated wood. The presence of the fire retardant in the treated wood or wood dust is not expected to affect its inherent toxicity characteristics. Carcinogenicity: PYRO-GUARD

® Treated Wood and its components are not listed as carcinogens by ACGIH, NIOSH,

of IARC. Wood dust is classified as a carcinogen by ACGIH, NIOSH, and IARC. This classification is based on an increased incidence of nasal and paranasal cancer in people exposed to wood dusts. Carcinogenicity of wood dust: ACGIH – A1 Confirmed Human Carcinogen (related to wood dusts-hard wood; NIOSH – Occupational carcinogen (related to wood dust); IARC -- Monograph 62, 1995 (related to wood dust)(Group 1 (carcinogenic to humans)). Wood Dust: Wood dust (softwood or hardwood): OSHA Hazard Rating = 3.3; moderately toxic with probable oral lethal dose to

humans being 0.5-5 g/kg (about 1 pound for a 70 kg or 150 pound person). Source: OSHA Regulated Hazardous Substances, Government Institutes, Inc., February 1990.

Carcinogenicity Listing: ⌧ NTP: Wood dust, Known Human Carcinogen ⌧ IARC Monographs: Wood dust, Group 1

OSHA Regulated: Not listed

NTP: According to its Tenth Report on Carcinogens, NTP states, “Wood dust is known to be a human carcinogen based

on sufficient evidence of carcinogenicity from studies in humans. An association between wood dust exposure and cancer of the nose has been observed in many case reports, cohort studies, and case-control studies that specifically addressed nasal cancer.

IARC – Group l: Carcinogenic to humans; sufficient evidence of carcinogenicity. This classification is primarily based on

studies showing an association between occupational exposure to wood dust and adenocarcinoma to the nasal cavities and paranasal sinuses. IARC did not find sufficient evidence of an association between occupational exposure to wood dust and cancers of the oropharynx, hypopharynx, lung, lymphatic and hematopoietic systems, stomach, colon or rectum.

Section 12. Ecological Information

Nitrogen is a critical element for plant growth and a basic constituent of proteins. In excess, however, it can make soil conditions less favorable for plant growth, damage aquatic life, and impair human health. Phosphorus is an essential nutrient for plants and animals; however, excessive accumulation of nutrients can represent too much of a good thing, especially in water bodies such as lakes, streams and estuaries. Loading of nutrients to surface waters causes changes in ecological function, and often has undesirable environmental and economic consequences. Borates have an excellent reputation for safety. In trace amounts, they’re essential micronutrients for plants and believed to be nutritionally important for people. In extreme doses, they can make you ill. As perspective, borates are about as acutely toxic as table salt. The United States Food and Nutrition Board (FNB) recently recognized the safety of boron by establishing a Tolerable Upper Intake Level (UL) for boron of 20 milligrams per day. Eutrophication is the enrichment of freshwater and marine systems with nutrients, particularly nitrogen and phosphorus.



Environmental Toxicity: None known. Environmental Fate: Wood is a naturally occurring product and decomposes into soil and soil enrichments. The nitrogen, phosphorus, and boron compounds are plant nutrients and are normal soil additives.

Section 13. Disposal Considerations

5. Fire Fighting Measures

FLAMMABLE PROPERTIES: Oxidizing agent; vigorously accelerates combustion. Contact with flammable materials may cause fire or explosion.

SUITABLE EXTINGUISHING MEDIA: Vigorously accelerates combustion. Use media appropriate for surrounding fire. Water (e.g., safety shower) is the preferred extinguishing method for clothing fires.

PRODUCTS OF COMBUSTION: Not applicable.

PROTECTION OF FIREFIGHTERS: WARNING! High-pressure, oxidizing gas. Evacuate all personnel from danger area. Immediately deluge cylinders with water from maximum distance until cool; then move them away from fire area if without risk. Self-contained breathing apparatus may be required by rescue workers. On-site fire brigades must comply with OSHA 29 CFR 1910.156.

Specific Physical and Chemical Hazards. Heat of fire can build pressure in cylinder and cause it to rupture. Oxygen cylinders are equipped with a pressure relief device. (Exceptions may exist where authorized by DOT.) No part of cylinder should be subjected to a temperature higher than 125°F (52°C). Smoking, flames, and electric sparks in the presence of enriched oxygen atmospheres are potential explosion hazards.

Protective Equipment and Precautions for Firefighters. Firefighters should wear self-contained breathing apparatus and full fire-fighting turnout gear.


STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED:

WARNING! High-pressure, oxidizing gas.

Personal Precautions. Shut off flow if without risk. Ventilate area or move cylinder to a well-ventilated area. Remove all flammable materials from vicinity. Oxygen must never be permitted to strike an oily surface, greasy clothes, or other combustible material.

Environmental Precautions. Prevent waste from contaminating the surrounding environment. Keep personnel away. Discard any product, residue, disposable container, or liner in an environmentally acceptable manner, in full compliance with federal, state, and local regulations. If necessary, call your local supplier for assistance.


PRECAUTIONS TO BE TAKEN IN HANDLING: Protect cylinders from damage. Use a suitable hand truck to move cylinders; do not drag, roll, slide, or drop. Never attempt to lift a cylinder by its cap; the cap is intended solely to protect the valve. Never insert an object (e.g., wrench, screwdriver, pry bar) into cap openings; doing so may damage the valve and cause a leak. Use an adjustable strap wrench to remove over-tight or rusted caps. Open valve slowly. If valve is hard to open, discontinue use and contact your supplier. Close cylinder valve after each use; keep closed even when empty. Never apply flame or localized heat directly to any part of the cylinder. High temperatures may damage the cylinder and could cause the pressure relief device to fail prematurely, venting the cylinder contents. For other precautions in using this mixture, see section 16.

PRECAUTIONS TO BE TAKEN IN STORAGE: Store and use with adequate ventilation, away from oil, grease, and other hydrocarbons. Separate oxygen cylinders from flammables by at least 20 ft (6.1 m) or use a barricade of noncombustible material. This barricade should be at least 5 ft (1.53 m) high and have a fire resistance rating of at least ½ hour. Firmly secure cylinders upright to keep them from falling or being knocked over. Screw valve protection cap firmly in place by hand. Store only where temperature will not exceed 125°F (52°C). Store full and empty cylinders separately. Use a first-in, first-out inventory system to prevent storing full cylinders for long periods.

RECOMMENDED PUBLICATIONS: For further information on storage, handling, and use, see Praxair publications P-14-153, Guidelines for Handling Gas Cylinders and Containers; P-15-276, Storage and Safe Handling of Oxygen; and P-3499, Safety Precautions and Emergency Response Planning.

ACUTE DOSE EFFECTS: The welding process may generate hazardous fumes and gases. (See sections 2, 10, 15, and 16.) At atmospheric concentration and pressure, oxygen poses no toxicity hazards. At high concentrations, newborn premature infants may suffer delayed retinal damage (retrolental fibroplasia) that can progress to retinal detachment and blindness. Retinal damage may also occur in adults exposed to 100% oxygen for extended periods (24 to 48 hours) or at pressures exceeding atmospheric pressure, particularly in individuals whose retinal circulation has been previously compromised. All individuals exposed for long periods to oxygen at high pressure and all who exhibit overt oxygen toxicity should have ophthalmologic examinations.

At two or more atmospheres, CNS toxicity occurs. Symptoms include nausea, vomiting, dizziness or vertigo, muscle twitching, vision changes, and loss of consciousness and generalized seizures. At three atmospheres, CNS toxicity occurs in less than two hours; at six atmospheres, in only a few minutes.


Page 6 of 10

Patients with chronic obstructive pulmonary disease retain carbon dioxide abnormally. If oxygen is administered, raising their blood-oxygen concentration, their breathing becomes depressed, and retained carbon dioxide rises to a dangerous level. Airway obstruction during high oxygen tension may cause alveolar collapse following absorption of the oxygen. Similarly, occlusion of the eustachian tubes may cause retraction of the eardrum, and obstruction of the paranasal sinuses may produce vacuum-type headache.

STUDY RESULTS: Animal studies suggest that the administration of certain drugs, including phenothiazine drugs and chloroquine, increases the susceptibility to toxicity from oxygen at high concentrations or pressures. Animal studies also indicate that vitamin E deficiency may increase susceptibility to oxygen toxicity.


ECOTOXICITY: No known effects.

OTHER ADVERSE EFFECTS: The atmosphere contains approximately 21% oxygen. No adverse ecological effects expected. Oxygen does not contain any Class I or Class II ozone-depleting chemicals.

Page 3 of 10

PROTECTION OF FIREFIGHTERS: DANGER! Flammable gas under pressure. Evacuate all personnel from danger area. Immediately cool cylinders with water spray from maximum distance, taking care not to extinguish flames. If flames are accidentally extinguished, explosive re-ignition may occur. Use self-contained breathing apparatus. Remove ignition sources if without risk. Stop flow of gas if without risk while continuing cooling water spray. Remove all cylinders from area of fire if without risk. Allow fire to burn out. On-site fire brigades must comply with OSHA 29 CFR 1910.156.

Specific Physical and Chemical Hazards. Heat of fire can build pressure in cylinder and cause it to rupture. Acetylene cylinders are provided with pressure relief devices designed to vent contents when exposed to elevated temperature. No part of a cylinder should be subjected

to a temperature higher than 125°F (52°C). If venting or leaking acetylene catches fire, do not extinguish flames. Flammable vapors may spread from leak, creating an explosive reignition hazard. Vapors can be ignited by pilot lights, other flames, smoking, sparks, heaters, electrical equipment, static discharge, or other ignition sources at locations distant from product handling point. Explosive atmospheres may linger. Before entering area, especially confined areas, check atmosphere with an approved explosion meter.

Protective Equipment and Precautions for Firefighters. Firefighters should wear self-contained breathing apparatus and full fire-fighting turnout gear.


STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED:

FUMES AND GASES can be dangerous to your health and may cause serious lung disease.

• Keep your head out of fumes. Do not breathe fumes and gases. Use enough ventilation, local exhaust, or both to keep fumes and gases from your breathing zone and the general area. Short-term overexposure to fumes may cause dizziness, nausea, and dryness or irritation of the nose, throat, and eyes or may cause other similar discomfort.

Fumes and gases cannot be classified simply. The amount and type depend on the metal being worked and the process, procedure, equipment, and supplies used. Possible dangerous materials may be found in fluxes, electrodes, and other materials. Get an MSDS for every material you use.

Contaminants in the air may add to the hazard of fumes and gases. One such contaminant, chlorinated hydrocarbon vapors from cleaning and degreasing activities, poses a special risk.

To find the quantity and content of fumes and gases, you can take air samples. By analyzing these samples, you can find out what respiratory protection you need. One recommended sampling method is to take air from inside the worker’s helmet or from the worker’s breathing zone. See AWS F1.1, Methods for Sampling and Analyzing Gases for Welding and Allied Processes, available from the American Welding Society, 550 N.W. Le Jeune Rd., Miami, FL 33126.

NOTES TO PHYSICIAN: Acute: Gases, fumes, and dusts may cause irritation to the eyes, lungs, nose, and throat. Some toxic gases associated with welding and related processes may cause pulmonary edema, asphyxiation, and death. Acute overexposure may include signs and symptoms such as watery eyes, nose and throat irritation, headache, dizziness, difficulty breathing, frequent coughing, or chest pains. Chronic: Protracted inhalation of air contaminants may lead to their accumulation in the lungs, a condition that may be seen as dense areas on chest x-rays. The severity of change is proportional to the length of exposure. The changes seen are not necessarily associated with symptoms or signs of reduced lung function or disease. In addition, the changes on x-rays may be caused by non-work-related factors such as smoking, etc.

PROTECTIVE CLOTHING AND EQUIPMENT FOR WELDING OPERATIONS:

PROTECTIVE GLOVES: Wear welding gloves.

EYE PROTECTION: Wear a helmet or use a face shield with a filter lens. Select lens per ANSI Z49.1. Provide protective screens and flash goggles if needed to protect others; select per OSHA 29 CFR 1910.133.

OTHER PROTECTIVE EQUIPMENT: Wear hand, head, and body protection. (See ANSI Z49.1.) Worn as needed, these help prevent injury from radiation, sparks, and electrical shock. Minimum protection includes welder’s gloves and a face shield. For


Page 9 of 10

added protection, consider arm protectors, aprons, hats, shoulder protection, and dark, substantial clothing.

OTHER HAZARDOUS CONDITIONS OF HANDLING, STORAGE, AND USE: Flammable gas under pressure. Use piping and equipment adequately designed to withstand pressures to be encountered. Acetylene systems should be installed only by persons knowledgeable of the unique properties of acetylene and trained and experienced in such installation. All piped acetylene systems and associated equipment must be grounded. Electrical equipment must be non-sparking or explosion-proof. Leak check with soapy water; never use a flame. Use a backflow prevention device in any piping. In choosing tools and equipment, avoid materials incompatible with acetylene. Copper, silver, and mercury and their salts, compounds, and high-concentration alloys can form explosive compounds with acetylene. Never use copper piping for acetylene service; use only steel or wrought iron. Brass containing less than 65% copper and certain nickel alloys are generally acceptable for use in acetylene service but may not be adequate if high corrosion or excess moisture is present. Never work on a pressurized system. If there is a leak, close the cylinder valve. Blow the system down in an environmentally safe manner in compliance with all federal, state, and local laws; then repair the leak. Never place a compressed gas cylinder where it may become part of an electrical circuit. Mixtures. When you mix two or more gases or liquefied gases, you can create additional, unexpected hazards. Obtain and evaluate the safety information for each component before you produce the mixture. Consult an industrial hygienist or other trained person when you evaluate the end product. Remember, gases and liquids have properties that can cause serious injury or death.

EFFECTS OF A SINGLE (ACUTE) OVEREXPOSURE:INHALATION–Asphyxiant. Effects are due to lack of oxygen. Moderate concentrations may causeheadache, drowsiness, dizziness, excitation, excess salivation, vomiting, and unconsciousness. Lackof oxygen can kill.SKIN CONTACT–No harm expected from vapor. Liquid may cause frostbite.SWALLOWING–An unlikely route of exposure. This product is a gas at normal temperature andpressure, but frostbite of the lips and mouth may result from contact with the liquid.EYE CONTACT–No harm expected from vapor. Liquid may cause frostbite.

EFFECTS OF REPEATED (CHRONIC) OVEREXPOSURE: No harm expected.

OTHER EFFECTS OF OVEREXPOSURE: At very high concentrations, propane may producecardiac arrhythmias or arrest due to sensitization of the heart to adrenaline and noradrenalin.

MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: The toxicology and thephysical and chemical properties of propane suggest that overexposure is unlikely to aggravate existingmedical conditions.

SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTHHAZARD EVALUATION: In a study conducted in 1948, dogs breathed varying mixtures ofhydrocarbons and oxygen for 10 minutes. Of a group of dogs exposed to propane, all (3 of 3) showedmyocardial sensitivity to injected epinephrine hydrochloride as determined by electrocardiogram (EKG)readings. No direct evidence is known of propane-induced cardiac sensitization in humans.

CARCINOGENICITY: Propane is not listed by NTP, OSHA, or IARC.

4. First Aid MeasuresINHALATION: Immediately remove to fresh air. If not breathing, give artificial respiration. Ifbreathing is difficult, qualified personnel may give oxygen. Call a physician.

SKIN CONTACT: For exposure to liquid, immediately warm frostbite area with warm water not toexceed 105°F (41°C). In case of massive exposure, remove contaminated clothing while showering withwarm water. Call a physician.

SWALLOWING: An unlikely route of exposure. This product is a gas at normal temperature andpressure.

EYE CONTACT: For contact with the liquid, immediately flush eyes thoroughly with warm water forat least 15 minutes. Hold the eyelids open and away from the eyeballs to ensure that all surfaces areflushed thoroughly. See a physician, preferably an ophthalmologist, immediately.

NOTES TO PHYSICIAN: This material may be a cardiac sensitizer; avoid the use of epinephrine.There is no specific antidote. Treatment of overexposure should be directed at the control of symptomsand the clinical condition of the patient.

EXTINGUISHING MEDIA: CO2, dry chemicals, water spray, or fog.

SPECIAL FIRE FIGHTING PROCEDURES: DANGER! Flammable liquid and gas underpressure. Evacuate all personnel from danger area. Immediately cool cylinders with water spray frommaximum distance, taking care not to extinguish flames. Remove ignition sources if without risk.Remove all cylinders from area of fire if without risk, while continuing cooling water spray. Do notextinguish any flames emitted from cylinders. Stop flow of gas if without risk, or allow flames to burnout. Self-contained breathing apparatus may be required by rescue workers. On-site fire brigades mustcomply with OSHA 29 CFR 1910.156.

UNUSUAL FIRE AND EXPLOSION HAZARDS: Flammable gas. Forms explosive mixtures with airand oxidizing agents. Heat of fire can build pressure in cylinder and cause it to rupture. No part ofcylinder should be subjected to a temperature higher than 125°F (52°C). Propane cylinders are equippedwith a pressure relief device. (Exceptions may exist where authorized by DOT.) If venting or leakingpropane catches fire, do not extinguish flames. Flammable gas may spread from leak, creating anexplosive re-ignition hazard. Vapors can be ignited by pilot lights, other flames, smoking, sparks, heaters,electrical equipment, static discharge, or other ignition sources at locations distant from product handlingpoint. Explosive atmospheres may linger. Before entering area, especially confined areas, checkatmosphere with an appropriate device.

HAZARDOUS COMBUSTION PRODUCTS: Carbon monoxide, carbon dioxide

6. Accidental Release MeasuresSTEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: DANGER! Flammableliquid and gas under pressure. Forms explosive mixtures with air. (See section 5.) Immediatelyevacuate all personnel from danger area. Use self-contained breathing apparatus where needed. Removeall sources of ignition if without risk. Reduce vapors with fog or fine water spray. Shut off flow ifwithout risk. Ventilate area or move cylinder to a well-ventilated area. Flammable vapors may spreadfrom leak. Before entering area, especially confined areas, check atmosphere with an approved device.

Section 4. First Aid Measures

Eye Exposure: Irrigate eyes with water and repeat until pain free. Seek medical attention if irritation develops or if vision changes occur.

of 8 Pages ABC

Skin Exposure: In case of contact, wash with plenty of soap and water. Seek medical attention if irritation develops. Inhalation: If respiratory irritation or distress occurs remove victim to fresh air. Seek medical attention if irritation persists. Ingestion: If victim is conscious and alert, give 2-3 glasses of water to drink and do not induce vomiting. Seek immediate medical attention. Do not leave victim unattended. To prevent aspiration of swallowed product, lay victim on side with head lower than waist. If vomiting occurs and the victim is conscious, give water to further dilute the chemical. Medical conditions possibly aggravated by exposure: Inhalation of product may aggravate existing chronic respiratory problems such as asthma, emphysema, or bronchitis. Skin contact may aggravate existing skin disease. Chronic overexposure may cause pneumoconiosis (“dusty lung” disease).

Section 5. Fire fighting measures

Extinguishing media: non combustible and non flammable – product is an extinguishing agent. Unusual fire/explosion hazards: in a fire this material may decompose, releasing oxides of sulfur and carbon (see Section 10). Insensitive to mechanical impact or static discharge. HMIS Hazard Ranking: health = 1, flammability = 0, reactivity = 0, personal protective equipment: ½ mask APR w/HEPA cartridges (see Section 8).

Section 6. Accidental release measures

Clean up released material using vacuum or wet sweep and shovel to minimize generation of dust. Wear appropriate respiratory protection. Bag and drum for disposal. If product is used and/or contaminated, use PPE and containment appropriate to the nature of the mixture. Prevent material from entering waterways.

of 8 Pages ABC

Section 7. Handling and storage

Avoid skin, eye, or respiratory exposure. Use appropriate PPE when handling or maintaining equipment, and wash thoroughly after handling (see Section 8). Keep product in original container or extinguisher. Contents may be under pressure – inspect for extinguisher rust periodically to insure container integrity. Do not mix with other extinguishing agents.

Section 8. Exposure controls/ personal protection

During the application of this product against fires, exhaust gases and the products of incomplete combustion (PICs) are the principal respiratory hazards. In the manufacture of extinguishers, automated systems and point source ventilation controls sufficiently minimize respiratory exposure. Employers and employees must use their collective judgment in determining occupational settings where the use of a dust mask or air purifying respirator is prudent. The need for respiratory protection is not likely for short-term use in well ventilated areas.

Respiratory protection: use N95 dust mask or air-purifying respirator (APR) with high efficiency particulate air (HEPA) filters. Eye protection: wear chemical goggles. Skin protection: use nitrile, latex, or similar gloves and coveralls. Good personal hygiene practices essential, such as avoiding food, tobacco products, or other hand-to-mouth contact when handling. Wash thoroughly after handling.

MOLTEN MATERIAL MAY CAUSE THERMAL BURNS Potential Health Effects Note: Steel products in their solid state under normal conditions, do not present an inhalation, ingestion or skin hazard. However, operations resulting in fume or particulate formation such as welding, sawing, brazing, grinding and machining may present health hazards. Molten steel also is hazardous. Eye Contact Dusts or particulates may cause mechanical irritation including pain, tearing, and redness. Scratching of the cornea can occur if eye is rubbed. Fumes may be irritating. Contact with the heated material may cause thermal burns. Skin Contact Dusts or particulates may cause mechanical irritation due to abrasion. Coated steel may cause skin irritation in sensitive individuals (see Section 16 for additional information.) Some components in this product are capable of causing an allergic reaction, possibly resulting in burning, itching and skin eruptions. Contact with heated material may cause thermal burns. Inhalation



Dusts may cause irritation of the nose, throat, and lungs. Excessive inhalation of metallic fumes and dusts may result in metal fume fever, an influenza-like illness. It is characterized by a sweet or metallic taste in the mouth, accompanied by dryness and irritation of the throat, cough, shortness of breath, pulmonary edema, general malaise, weakness, fatigue, muscle and joint pains, blurred vision, fever and chills. Typical symptoms last from 12 to 48 hours. Ingestion Not expected to be acutely toxic via ingestion based on the physical and chemical properties of the product. Swallowing of excessive amounts of the dust may cause irritation, nausea, and diarrhea. Chronic or Special Toxic Effects Repeated exposure to fine dusts may inflame the nasal mucosa and cause changes to the lung. In addition, a red-brown pigmentation of the eye and/or skin may occur. Welding fumes have been associated with adverse health effects. Contains components that may cause cancer or reproductive effects. The following components are listed by NTP, OSHA, or IARC as carcinogens: Nickel, chromium (hexavalent), cobalt, lead, cadmium, antimony (trioxide), arsenic, beryllium. See Section 11, for additional, specific information on effects noted above. Target Organs Overexposure to specific components of this product that are generated in dusts or fumes may cause adverse effects to the following organs or systems: eyes, skin, liver, kidney, central nervous system, cardiovascular system, respiratory system,. Medical Conditions Aggravated by Exposure Diseases of the skin such as eczema may be aggravated by exposure. Also, disorders of the respiratory system including asthma, bronchitis, and emphysema. Long-term inhalation exposure to agents that cause pneumoconiosis (e.g. dust) may act synergistically with inhalation of oxide fumes or dusts of this product.

4. FIRST AID MEASURES Eye Contact- In case of overexposure to dusts or fumes, immediately flush eyes with plenty of water for at least 15 minutes occasionally lifting the eye lids. Get medical attention if irritation persists. Thermal burns should be treated as medical emergencies. Skin Contact - In case of overexposure to dusts or particulates, wash with soap and plenty of water. Get medical attention if irritation develops or persists. If thermal burn occurs, flush area with cold water and get immediate medical attention. Inhalation - In case of overexposure to dusts or fumes, remove to fresh air. Get immediate medical attention if symptoms described in this MSDS develop. Ingestion - Not considered an ingestion hazard. However, if excessive amounts of dust or particulates are swallowed, treat symptomatically and supportively. Get medical attention. Notes to Physician - Inhalation of metal fume or metal oxides may produce an acute febrile state, with cough, chills, weakness, and general malaise, nausea, vomiting, muscle cramps, and remarkable leukocytosis. Treatment is symptomatic, and condition is self limited in 24-48 hours. Chronic exposure to dusts may result in pneumoconiosis of mixed type.

5. FIRE FIGHTING MEASURES Flash Point (Method) - Not applicable Flammable Limits (% volume in air) - Not applicable Autoignition Temperature - Not applicable Extinguishing Media - For molten metal, use dry powder or sand. Special Fire Fighting Procedures - Do not use water on molten metal.

Avoid inhalation, eye, or skin contact of dusts by using appropriate precautions outlined in this MSDS (see section 8). Fine turnings and small chips should be swept or vacuumed and placed into appropriate disposable containers. Keep fine dust or powder away from sources of ignition. Scrap should be reclaimed for recycling. Prevent materials from entering drains, sewers, or waterways. Environmental Precautions - Some grades of steel may contain reportable quantities of alloying elements. See Section 15 for additional information. Waste Disposal Methods - Dispose used or unused product in accordance with applicable Federal, State, and Local regulations.

7. HANDLING AND STORAGE Storage Temperatures - Stable under normal temperatures and pressures. Precautions to be Taken in Handling and Storing - Store away from strong oxidizers. Dusts or powders may form explosive mixtures with air. Avoid breathing dusts or fumes.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION Operations with potential for generating high concentrations of airborne particulates or fumes should be evaluated and controlled as necessary. Eye Protection - Use safety glasses. Dust resistant safety goggles are recommended under circumstances where particles could cause mechanical injury such as grinding or cutting. Face shield should be used when welding or cutting. Skin - Appropriate protective gloves should be worn as necessary. Good personal hygiene practices should be followed including cleansing exposed skin several times daily with soap and water, and laundering or dry cleaning soiled work clothing. Respiratory Protection - NIOSH/MSHA approved dust/fume/mist respirator should be used to avoid excessive exposure. See Section 2 for component material information exposure limits. If such concentrations are sufficiently high that this respirator is inadequate, or high enough to cause oxygen deficiency, use a positive pressure self-contained breathing apparatus (SCBA). Follow all applicable respirator use, fitting, and training standards and regulations. Ventilation - Provide general and/or local exhaust ventilation to control airborne levels of dust or fumes below exposure limits. Exposure Guidelines - No permissible exposure limits (PEL) or threshold limit values (TLV) exist for steel. See Section 2 for component materials. Various grades of steel will contain different combinations of these elements. Trace elements may also be present in minute amounts.

11. TOXICOLOGICAL INFORMATION The primary component of this product is iron. Long-term exposure to iron dusts or fumes can result in a condition called siderosis which is considered to be a benign pneumoconiosis. Symptoms may include chronic bronchitis, emphysema, and shortness of breath upon exertion. Penetration of iron particles in the skin or eye may cause an exogenous or ocular siderosis which may be characterized by a red-brown pigmentation of the affected area. Ingestion overexposures to iron may affect the gastrointestinal, nervous, and hematopoietic system and the liver. Iron and steel founding, but not iron or iron oxide, has been listed as potentially carcinogenic by IARC. When this product is welded, fumes are generated. Welding fumes may be different in composition from the original welding product, with the chief component being ordinary oxides of the metal being welded. Chronic health effects (including cancer) have been associated with the fumes and dusts of individual component metals (see above), and welding fumes as a general category have been listed by IARC as a carcinogen (Group 2B). There is also limited evidence that welding fumes may cause adverse reproductive and fetal effects. Evidence is stronger where welding materials contain known reproductive toxins, e.g., lead which may be present in the coating material of this product. Breathing fumes or dusts of this product may result in metal fume fever, which is an illness produced by inhaling metal oxides. These oxides are produced by heating various metals including cadmium, zinc, magnesium, copper, antimony, nickel, cobalt, manganese, tin, lead, beryllium, silver, chromium, aluminum, selenium, iron, and arsenic. The most common agents involved are zinc and copper. This product may contain small amounts of manganese. Prolonged exposure to manganese dusts or fumes is associated with "manganism", a Parkinson-like syndrome characterized by a variety of neurological symptoms including muscle spasms, gait disturbances, tremors, and psychoses. This product may contain small amounts of cadmium. Primary target organs for cadmium overexposure are the lung and the kidney. Because of its cumulative nature, chronic cadmium poisoning can cause serious disease which takes many years to develop and may continue to progress despite cessation of exposure. Progression of the disease may not reflect current exposure conditions. It is also capable of causing a painful osteomalacia called “Itai-Itai” in postmenopausal women, and has cause developmental effects and/or reproductive effects in male and female animals. Cadmium is a listed carcinogen by NTP, OSHA, and IARC (Group 1). This product may contain small amounts of chromium. Prolonged and repeated overexposure to chromium dusts or fumes may cause skin ulcers, nasal irritation and ulceration, kidney damage and cancer of the respiratory system. Chromium is skin sensitizer. Cancer is generally attributed to the hexavalent (+6) form of chromium which is listed as a carcinogen by NTP and IARC (Group 1). This product may contain small amounts of nickel. Prolonged and repeated contact with nickel may cause sensitization dermatitis. Inhalation of nickel compounds has caused lung damage as well as sinus, nasal and lung cancer in laboratory animals. Nickel is a listed carcinogen by NTP and IARC (Group 1). This product may contain small amounts of vanadium. Adverse effects from dermal, inhalation or parenteral exposure to various vanadium compounds have been reported. The major target for vanadium pentoxide toxicity is the respiratory tract. Fumes or dust can cause severe eye and respiratory irritation, and systemic effects. Chronic bronchitis, green tongue, conjunctivitis, pharyngitis, rhinitis, rales, chronic productive cough, and tightness of the chest have been reported following overexposure. Allergic



reactions resulting from skin and inhalation exposures have also been reported. A statistical association between vanadium air levels and lung cancer has been suggested, but vanadium currently is not regarded as a human carcinogen. This product may contain small amounts of lead. Lead can accumulate in the body. Consequently, exposure to fumes or dust may produce signs of polyneuritis, diminished vision and peripheral neuropathy, such as tingling and loss of feeling in fingers, arms and legs. Lead is a known reproductive and developmental toxin. It is also associated with central nervous system disorders, anemia, kidney disfunction and neurobehavioral abnormalities. The brain is a major target organ for lead exposure. Elemental lead is listed as an IARC 2B carcinogen. The product may contain small amounts of copper. Copper dust and fume can irritate the eyes, nose and throat causing coughing, wheezing, nosebleeds, ulcers and metal fume fever. Other effects from repeated inhalation of copper fume include a metallic or sweet taste, and discoloration of skin, teeth or hair. Copper also may cause an allergic skin reaction. Overexposure to copper can affect the liver.

REACTIVITY DATA

Hazardous Polymerization: Will not occur. Stability: Stable.

Incompatibility: Strong acids and oxidizing agents.

Decomposition Products: Oxides of nitrogen, oxides of carbon, acrid fumes and lead oxide.

Conditions to Avoid: Acids, excessive heat, crushing, and electrical currents.

HEALTH HAZARD DATA

Known Hazards: OSHA has established an action level of 0.03 mg/m3 for lead. Exposures that exceed

recommended limits for lead may be possible under certain conditions such as excessivefiring with little air movement and/or firing in small enclosed work areas. Chronic (long-term)overexposure to lead can result in damage to blood-forming, nervous, urinary and reproductivesystems.

Signs and Symptoms ofExposure:

Excessive exposure to gases might cause irritation to the eyes, skin, and respiratory system.Adverse health effects are not expected from acute exposure to fumes and gases; however,adequate ventilation, personal protective equipment, and/or good personal hygiene practicesare essential to keep exposure to a minimum.

Routes of Exposure: Dermal. Inhalation.

Carcinogenicity: Organic lead compounds are not classified by IARC or NTP as carcinogens. Lead styphnate isconverted to metallic lead and lead oxide during combustion. Metallic lead and lead oxidehave not been tested adequately. A study by Goyer and Rhyne (1973) concluded that "there isno evidence that lead produces cancer in man".


Medical ConditionsAggravated by Exposure:

None anticipated.


Eyes: If irritation occurs, flush with plenty of water. Consult a physician if symptoms persist.

Skin: Practice good hygiene; i.e. wash with soap and water after using and before meals.

Inhalation: Move victim to fresh air. Get medical attention if symptoms persist.

Ingestion: Get immediate medical attention.

Other: Seek prompt medical attention if physical injury occurs from pins, rivets, debris, etc. Forbleeding wounds, place a clean cloth or similar absorbent material on the wound and applyfirm pressure. Elevate the wound and transport immediately to a medical facility.


Ventilation: General (i.e., natural or mechanically induced fresh air movements that maintain vaporconcentrations below recommended exposure limits).

Eye Protection: Safety glasses with side-shields, as a minimum. Safety goggles recommended.

Skin Protection: Cleaning powder actuated tools can result in some exposure to lead compounds. Clothgloves are recommended, otherwise, wash hands thoroughly when finished and before eatingor smoking.

Respiratory Protection: Not normally required. Where air movement is inadequate to maintain exposure belowrecommended levels, wear a high efficiency particulate respirator.

Other: Hearing protection (muffs or aural inserts) should be worn when firing powder actuated tools


Handling and StoringPrecautions:

Store in a cool dry place. Do not crush or drop. Keep away from excessive heat (such asextremely hot surfaces and flames), electrical current, strong acids and oxidizers. NFPA 495requires 15 feet separation (or 1-hour firewall) from flammable liquids, flammable solids, andoxidizers. For industrial use only. Keep out of reach of children. Use with adequateventilation. Practice good hygiene; i.e. wash after using and before eating or smoking.

Other Precautions:: Use only in powder actuated tools designed to handle these boosters. Construction industryemployees must be properly trained as prescribed by OSHA regulations 29 CFR 1926.302 (e).All employees should be familiar with the safe operating procedures and requirements forpowder operated tools as described in ANSI A10.3 and OSHA 29 CFR 1910.243 (d).
