EMERGENCY OVERVIEW
RISK
Irritating to eyes. HARMFUL - May cause lung damage if swallowed. Harmful by inhalation, in contact with skin and if swallowed. Harmful: possible risk of irreversible effects through inhalation, in contact with skin and if swallowed. Flammable. Repeated exposure potentially causes skin dryness and cracking*. Vapours potentially cause drowsiness and dizziness*. Cumulative effects may result following exposure*. May produce discomfort of the respiratory system*. Possible cancer-causing agent*. * (limited evidence).
POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to the health of the individual. HARMFUL-May cause lung damage if swallowed.
EYE
Evidence exists, or practical experience predicts, that the material may cause eye irritation in a substantial number of individuals and/or may produce significant ocular lesions which are present twenty-four hours or more after instillation into the eye(s) of experimental animals.
-
KMC LP Emul S Page 4 of 21
SKIN
Skin contact with the material may be harmful; systemic effects may result following absorption. Repeated exposure potentially causes skin dryness and cracking*. The material is not thought to be a skin irritant (i.e. is unlikely to produce irritant dermatitis as described in EC Directives using animal models). Temporary discomfort, however, may result from prolonged dermal exposures. Good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.
INHALED
Harmful by inhalation. Limited evidence exists, or practical experience predicts, that the material produces irritation of the respiratory system in a significant number of individuals following inhalation. Vapours potentially cause drowsiness and dizziness*.
CHRONIC HEALTH EFFECTS
Cumulative effects may result following exposure*. On the basis, primarily, of animal experiments, concern has been expressed that the material may produce carcinogenic or mutagenic effects; in respect of the available information, however, there presently exists inadequate data for making a satisfactory assessment. On the basis of limited epidemiological data, the material is regarded as carcinogenic to humans. At least one classification body considers that there is sufficient data to establish a causal association between human exposure to the material and the development of cancer. Principal routes of exposure are by accidental skin and eye contact and by inhalation of vapours especially at higher temperatures. The principal routes of exposure are usually by skin contact/absorption and pressure and volatility of mineral oil at room temperature present a negligible vapour hazard under normal working conditions. Prolonged contact with mineral oils carries with it the risk of skin conditions such as oil folliculitis, eczematous dermatitis, pigmentation of the face (melanosis) and warts on the sole of the foot (plantar warts). With highly refined mineral oils no appreciable systemic effects appear to result through skin absorption. Exposure to oil mists frequently elicits respiratory conditions, such as asthma; the provoking agent is probably an additive. High oil mist concentrations may produce lipid pneumonia although clinical evidence is equivocal. In animals

KMC LP Emul S Page 5 of 21
exposed to concentrations of 100 mg/m3 oil mist, for periods of 12 to 26 months, the activity of lung and serum alkaline phosphatase enzyme was raised; 5 mg/m3 oil mist did not produce this response. These enzyme changes are sensitive early indicators of lung damage. Many studies have linked cancers of the skin and scrotum with mineral oil exposure. Contaminants in the form of additives and the polycyclic aromatic hydrocarbons (PAHs - found in the crude base stock) are probably responsible. PAH levels are higher in aromatic process oils and used/reclaimed motor oils. Mineral oils in certain cosmetics have been shown to act as immunological adjuvants in susceptible rats i.e. they can contribute to the activation of the immune system, and have also been shown to produce arthritis following topical application to these rats. Long-term exposure to methanol vapour, at concentrations exceeding 3000 ppm, may produce cumulative effects characterised by gastrointestinal disturbances (nausea, vomiting), headache, ringing in the ears, insomnia, trembling, unsteady gait, vertigo, conjunctivitis and clouded or double vision. Liver and/or kidney injury may also result. Some individuals show severe eye damage following prolonged exposure to 800 ppm of the vapour.
Section 5 - FIRST AID MEASURES
SWALLOWED
If poisoning occurs, contact a doctor or Poisons Information Centre. · If swallowed do NOT induce vomiting. · If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration. · Observe the patient carefully. · Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconsciousness · Give water to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink. · Seek medical advice.
EYE
If this product comes in contact with the eyes: · Immediately hold eyelids apart and flush the eye continuously with running water. · Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. · Continue flushing until advised to stop by the Poisons Information Centre or a doctor, or for at least 15 minutes.
-
KMC LP Emul S Page 6 of 21
· Transport to hospital or doctor without delay. · Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.
SKIN
If skin contact occurs: · Immediately remove all contaminated clothing, including footwear · Flush skin and hair with running water (and soap if available). · Seek medical attention in event of irritation.
INHALED
· If fumes or combustion products are inhaled remove from contaminated area. · Lay patient down. Keep warm and rested. · Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures. · Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary. · Transport to hospital, or doctor.
NOTES TO PHYSICIAN
For acute and short term repeated exposures to methanol:
· Toxicity results from accumulation of formaldehyde/formic acid.
· Clinical signs are usually limited to CNS, eyes and GI tract Severe
metabolic
acidosis may produce dyspnea and profound systemic effects which may
become
intractable. All symptomatic patients should have arterial pH measured.
Evaluate
airway, breathing and circulation.
· Stabilise obtunded patients by giving naloxone, glucose and thiamine.
· Decontaminate with Ipecac or lavage for patients presenting 2 hours
post-ingestion. Charcoal does not absorb well; the usefulness of
cathartic is
not established.
· Forced diuresis is not effective; haemodialysis is recommended where
peak
methanol levels exceed 50 mg/dL (this correlates with serum bicarbonate
levels
below 18 mEq/L)
· Ethanol, maintained at levels between 100 and 150 mg/dL, inhibits
formation of
toxic metabolites and may be indicated when peak methanol levels exceed
20
mg/dL. An intravenous solution of ethanol in D5W is optimal.
· Folate, as leucovarin, may increase the oxidative removal of formic
acid.

B: Background levels occur in specimens collected from subjects NOT
exposed.
NS: Non-specific determinant - observed following exposure to other
materials.
For acute or short term repeated exposures to petroleum distillates or
related
hydrocarbons:
· Primary threat to life, from pure petroleum distillate ingestion
and/or
inhalation, is respiratory failure.
· Patients should be quickly evaluated for signs of respiratory
distress (e.g.
cyanosis, tachypnoea, intercostal retraction, obtundation) and given
oxygen.
Patients with inadequate tidal volumes or poor arterial blood gases
(pO2 50 mm
Hg) should be intubated.
· Arrhythmias complicate some hydrocarbon ingestion and/or inhalation
and
electrocardiographic evidence of myocardial injury has been reported;
intravenous lines and cardiac monitors should be established in
obviously
symptomatic patients. The lungs excrete inhaled solvents, so that
hyperventilation improves clearance
· A chest x-ray should be taken immediately after stabilisation of
breathing and
circulation to document aspiration and detect the presence of
pneumothorax.
· Epinephrine (adrenalin) is not recommended for treatment of
bronchospasm
because of potential myocardial sensitisation to catecholamines.
Inhaled
cardioselective bronchodilators (e.g. Alupent, Salbutamol) are the
preferred
agents, with aminophylline a second choice.
· Lavage is indicated in patients who require decontamination; ensure
use of
cuffed endotracheal tube in adult patients. [Ellenhorn and Barceloux:

Section 6 - FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA
Alcohol stable foam. Dry chemical powder. BCF (where regulations permit). Carbon dioxide. Water spray or fog - Large fires only.
FIRE FIGHTING
· Alert Fire Brigade and tell them location and nature of hazard. · May be violently or explosively reactive. · Wear breathing apparatus plus protective gloves for fire only. · Prevent, by any means available, spillage from entering drains or water course. · If safe, switch off electrical equipment until vapour fire hazard removed. · Use water delivered as a fine spray to control fire and cool adjacent area. · Avoid spraying water onto liquid pools. · DO NOT approach containers suspected to be hot. · Cool fire exposed containers with water spray from a protected location. · If safe to do so, remove containers from path of fire. · Equipment should be thoroughly decontaminated after use. When any large container (including road and rail tankers) is involved in a fire, consider evacuation by 500 metres in all directions.
FIRE/EXPLOSION HAZARD
· Liquid and vapour are flammable. · Moderate fire hazard when exposed to heat or flame. · Vapour forms an explosive mixture with air. · Moderate explosion hazard when exposed to heat or flame. · Vapour may travel a considerable distance to source of ignition. · Heating may cause expansion or decomposition leading to violent rupture of containers. · On combustion, may emit toxic fumes of carbon monoxide (CO). Other combustion products include nitrogen oxides (NOx) , sulfur oxides (SOx) and aldehydes
FIRE INCOMPATIBILITY
Avoid contamination with oxidising agents i.e. nitrates, oxidising acids, chlorine bleaches, pool chlorine etc. as ignition may result

PROTECTIVE ACTIONS FOR SPILL
-
KMC LP Emul S Page 10 of 21
From IERG (Canada/Australia)
Isolation Distance 25 metres
Downwind Protection Distance 300 metres
FOOTNOTES
1 PROTECTIVE ACTION ZONE is defined as the area in which people are at
risk
of harmful exposure. This zone assumes that random changes in wind
direction
confines the vapour plume to an area within 30 degrees on either
side of the
predominant wind direction, resulting in a crosswind protective
action distance
equal to the downwind protective action distance.
2 PROTECTIVE ACTIONS should be initiated to the extent possible,
beginning with
those closest to the spill and working away from the site in the
downwind
direction. Within the protective action zone a level of vapour
concentration
may exist resulting in nearly all unprotected persons becoming
incapacitated
and unable to take protective action and/or incurring serious or
irreversible
health effects.
3 INITIAL ISOLATION ZONE is determined as an area, including upwind of
the
incident, within which a high probability of localised wind reversal
may
expose nearly all persons without appropriate protection to life-
threatening
concentrations of the material.
4 SMALL SPILLS involve a leaking package of 200 litres (55 US gallons)
or less,
such as a drum (jerrican or box with inner containers). Larger
packages leaking
less than 200 litres and compressed gas leaking from a small
cylinder are also
considered "small spills".
LARGE SPILLS involve many small leaking packages or a leaking
package of
greater than 200 litres, such as a cargo tank, portable tank or a
"one-tonne"

Odour Safety Factor (OSF) is determined to fall into either Class
C, D or E.
The Odour Safety Factor (OSF) is defined as:
OSF= Exposure Standard (TWA) ppm/ Odour Threshold Value (OTV) ppm
Classification into classes follows:

individuals are aware by
smell that the Exposure
Standard (TLV-TWA for
example) is being
reached, even when
distracted by working
activities

REPRODUCTIVE HEALTH GUIDELINES
Established occupational exposure limits frequently do not take
into
consideration reproductive end points that are clearly below the
thresholds for
other toxic effects. Occupational reproductive guidelines (ORGs)
have been
suggested as an additional standard. These have been established
after a
literature search for reproductive no-observed-adverse effect-level
(NOAEL) and
the lowest-observed-adverse-effect-level (LOAEL). In addition the
US EPA's
procedures for risk assessment for hazard identification and dose-
response
assessment as applied by NIOSH were used in the creation of such
limits.

The local concentration of material, quantity and conditions of use
determine
the type of personal protective equipment required. For further
information
consult site specific CHEMWATCH data (if available), or your
Occupational
Health and Safety Advisor.
ENGINEERING CONTROLS General exhaust is adequate under normal operating conditions. Local
exhaust
ventilation may be required in specific circumstances. If risk of
overexposure
exists, wear approved respirator. Correct fit is essential to obtain
adequate
protection. Provide adequate ventilation in warehouse or closed storage
areas.
Air contaminants generated in the workplace possess varying "escape"
velocities
which, in turn, determine the "capture velocities" of fresh circulating
air
required to effectively remove the contaminant.
Type of Contaminant: Air Speed:
solvent, vapours, degreasing etc., 0.25-0.5 m/s (50-100 f/min)
evaporating from tank (in still air).
aerosols, fumes from pouring 0.5-1 m/s (100-200 f/min.)
operations, intermittent container
filling, low speed conveyer transfers,
welding, spray drift, plating acid
fumes, pickling (released at low

generation)
direct spray, spray painting in shallow 1-2.5 m/s (200-500 f/min.)
booths, drum filling, conveyer loading,
crusher dusts, gas discharge (active
generation into zone of rapid air
motion)
grinding, abrasive blasting, tumbling, 2.5-10 m/s (500-2000 f/min.)
high speed wheel generated dusts
(released at high initial velocity into
zone of very high rapid air motion).
Within each range the appropriate value depends on:
Lower end of the range Upper end of the range
1: Room air currents minimal or 1: Disturbing room air currents
favourable to capture
2: Contaminants of low toxicity or of 2: Contaminants of high toxicity
nuisance value only.
3: Intermittent, low production. 3: High production, heavy use
4: Large hood or large air mass in 4: Small hood-local control only
motion
Simple theory shows that air velocity falls rapidly with distance away
from the
opening of a simple extraction pipe. Velocity generally decreases with
the
square of distance from the extraction point (in simple cases).
Therefore the
air speed at the extraction point should be adjusted, accordingly,
after
reference to distance from the contaminating source. The air velocity
at the
extraction fan, for example, should be a minimum of 1-2 m/s (200-400
f/min) for
extraction of solvents generated in a tank 2 meters distant from the
extraction
point. Other mechanical considerations, producing performance deficits
within
the extraction apparatus, make it essential that theoretical air
velocities are
multiplied by factors of 10 or more when extraction systems are
installed or
used.

PETROLEUM RAFFINATE, SORPTION PROCESS:
Toxicity and Irritation data is related to chemical components and
varies as does the composition and source of the original crude.
A small but definite risk of occupational skin cancer occurs in workers
exposed to persistent skin contamination by oils over a period of
years.
This risk has been attributed to the presence of certain polycyclic
aromatic hydrocarbons (PAH) (typified by benz[a]pyrene).
Petroleum oils which are solvent refined/extracted or severely
hydrotreated,
