HAZCOM Program

aka the Right to Know Program elements:1. Written Hazard Communication Program2. Training3. Inventory4. Material Safety Data Sheets (MSDSs)5. Labeling

HAZCOM Training Objectives

By the end of the course, you will be able to:1. Explain HAZCOM training requirements2. Explain details of a HAZCOM Program3. Identify ways chemicals affect your body, 4. Identify hazardous chemicals in your work area

and ways to protect yourself (i.e. personal protective equipment)

5. Define a material safety data sheet (MSDS) and where it is located in your work area

6. Explain labeling

What You Need To Know

Ask the Following Questions:• How can this material hurt me? • What can I do to protect myself?• Where can I find the answers to the first two questions?

LabelingWhat Must Be Labeled?• Labels must appear either on • the container itself• the batch ticket• placard, or• process sheets

• Exception to Rule: hazardous chemicals in portable containers which are for the immediate use of the employee who performs the transfer

LabelingOSHA requires following on be

included on ALL labels: 1. The product name;2. A warning statement, message

or symbol; and 3. On commercial labels,

manufacturers of hazardous materials must include their name and address. Many manufacturers also include a statement describing safe handling procedures.

Sample LabelRx Company Isopropyl Alcohol

Flammable – Keep away from fire and flame.

Warning – For external use only. If taken internally, serious gastric disturbances will results. In case of accidental ingestion, call physician immediately.Rx Co, 123 Main St, Anytown, NY 12345

Labeling

Label Review• Where are two places you can find

information about hazards in your workplace?

• Hazard classes on labels are represented by a) numbers

b) letters c) colors

• T or F: Only very hazardous material must be labeled.

• T or F: The higher the number on a rating scale, the less dangerous the substance.

• Does the following label contain all of the required information for a commercial label?

Review

• Isopropyl Alcohol

• Flammable – Keep away from fire and flame.

• Warning – For external use only. If taken internally, serious gastric disturbances will result. In case of accidental ingestion, call physician immediately.

MATERIAL SAFETY DATA SHEETS (MSDS)

MSDSs are printed material which provide detailed health and safety information and precautions for handling hazardous substances, including emergency and first aid procedures.

WHAT INFO IS ON AN MSDS?

• Identity of the chemical (name of product)• Physical hazards• Health hazards• Routes of entry into body• Permissible exposure limits (PELs)• Carcinogenic factors (cancer-causing)• Safe handling procedures• Date• Control measures (i.e. gloves, goggles)• First aid• Contact info

WHEN DO YOU USE AN MSDS?

MSDS Review

• Name 3 pieces of info listed on an MSDS .

• T or F. Material Safety Data Sheets are NOT available for all hazardous materials present in your work area.

• T or F. You should use an MSDS whenever you need additional info about a hazardous material that is not included on the product label.

• Whose responsibility is it to know where the MSDS is located?

• Physical Hazards1

• Health Hazards2

Two Classes of Hazards

Physical HazardsPhysical Hazard Terms• Combustible -ignites over 100 degrees F• Flammables –ignites below 100 degrees F• Flash point – ignition temperature• Explosives • Pressure• Unstable

Physical Hazard Symbols – Fire Symbol

• Flammables• Combustibles• Pyrophoric

• http://www.youtube.com/watch?v=P1i55ixRedo&feature=related

Physical Hazard Symbols – Explosive Symbol

• Explosives release a tremendous amount of energy in form of heat, light, expanding pressure

• Water reactives

• Unstable reactives

Physical Hazard Symbols – Flaming “O” Symbol• Oxidizers• Organic peroxides

Physical Hazard Symbols – Cylinder Symbol

• Gas cylinders

Health HazardsHealth Hazard Terms• Corrosive - material that burns body

tissue• Toxin –material with the potential to

injure body systems by chemical reaction• Routes of EntryWays chemicals may enter the body:1. Inhalation (breathing)2. Ingestion (swallowing)3. Absorption (skin contact)4. Injection

Health Hazard TermsHealth Hazard TermsDose - amount of material an individual is

exposed to Dose Effects – 2 kinds; depends on the

concentration of material over a period of time:Acute effects: effects which occur immediately

or soon after you come in contact with them Chronic effects: effects which take years or

decades to occur after you are exposured many times

Health Hazard Terms –

Health Hazard Terms –

Health Hazard Symbols – Medical Symbol

Health Hazard Symbols – Skull & Crossbones Symbol

• Poisonous

Health Hazard Symbols – Corrosive Symbol

Health Hazard Symbols – Radioactive Symbol

Health Hazard Symbols – Biological Symbol

Protective Measures

• Product Substitution• Engineering Controls • Safe Work Practices • Personal Protective

Equipment • Training and

Communication • Environmental Monitoring• Personal Monitoring

Review• T or F. Liquid flammables ignite more easily than do liquid

combustibles.

• Which of the following material classes should NOT use an Explosive symbol? a) Explosives

b) Flammables c) Water Reactives d) Unstable Reactives

• T or F. The gas in a gas cylinder is stored under great pressure

• T or F. Dose is the only factor that determines how a substance might affect your health.

• T or F. Inhalation is the most common type of route of exposure.

• What protective measures will insure that safe exposure limits are not exceeded?

Review• What color indicates fire or

explosive hazards?

• Name a “caution phrase” that may be found on a chemical label.

Summary

• Consult your supervisor –what chemicals will you be working with?

• Read all safety instructions and labels• Review MSDSs• Review labels• Wear personal protective equipment• Know what to do in an emergency• Know storage requirements• Understand and obey the safety rules • Take safety home with you - the average workplace

is safer than the average home!
