Section 4 - FIRST AID MEASURES
SWALLOWED
Not considered a normal route of entry.
鈥? If swallowed do NOT induce vomiting.
鈥? If vomiting occurs, lean patient forward or place on left side (head-down
position, if possible) to maintain open airway and prevent aspiration.
鈥? Observe the patient carefully.
鈥? Never give liquid to a person showing signs of being sleepy or with reduced
awareness; i.e. becoming unconscious.
鈥? Give water to rinse out mouth, then provide liquid slowly and as much as
casualty can comfortably drink.
鈥? Seek medical advice.
EYE
If aerosols come in contact with the eyes:
鈥? Immediately hold the eyelids apart and flush the eye continuously for at least
15 minutes with fresh running water.
鈥? 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.
鈥? Transport to hospital or doctor without delay.
鈥? Removal of contact lenses after an eye injury should only be undertaken by
skilled personnel.
SKIN
If solids or aerosol mists are deposited upon the skin:
鈥? Flush skin and hair with running water (and soap if available).
鈥? Remove any adhering solids with industrial skin cleansing cream.
鈥? DO NOT use solvents.
鈥? Seek medical attention in the event of irritation.
INHALED
If aerosols, fumes or combustion products are inhaled:
鈥? Remove to fresh air.
鈥? Lay patient down. Keep warm and rested.
鈥? Prostheses such as false teeth, which may block airway, should be removed,
where possible, prior to initiating first aid procedures.
鈥? If breathing is shallow or has stopped, ensure clear airway and apply
resuscitation, preferably with a demand valve resuscitator, bag-valve mask
device, or pocket mask as trained. Perform CPR if necessary.

Section 4 - FIRST AID MEASURES
For sub-chronic and chronic exposures to isocyanates:
鈥? This material may be a potent pulmonary sensitiser which causes bronchospasm
even in patients without prior airway hyperreactivity.
鈥? Clinical symptoms of exposure involve mucosal irritation of respiratory and
gastrointestinal tracts.
鈥? Conjunctival irritation, skin inflammation (erythema, pain vesiculation) and
gastrointestinal disturbances occur soon after exposure.
鈥? Pulmonary symptoms include cough, burning, substernal pain and dyspnoea.
鈥? Some cross-sensitivity occurs between different isocyanates.
鈥? Noncardiogenic pulmonary edema and bronchospasm are the most serious
consequences of exposure. Markedly symptomatic patients should receive oxygen,
ventilatory support and an intravenous line.
鈥? Treatment for asthma includes inhaled sympathomimetics (epinephrine
[adrenalin], terbutaline) and steroids.
鈥? Activated charcoal (1 g/kg) and a cathartic (sorbitol, magnesium citrate) may
be useful for ingestion.
鈥? Mydriatics, systemic analgesics and topical antibiotics (Sulamyd) may be used
for corneal abrasions.
鈥? There is no effective therapy for sensitised workers.
[Ellenhorn and Barceloux; Medical Toxicology]
NOTE: Isocyanates cause airway restriction in naive individuals with the degree
of response dependant on the concentration and duration of exposure. They induce
smooth muscle contraction which leads to bronchoconstrictive episodes. Acute
changes in lung function, such as decreased FEV1, may not represent sensitivity.

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"
compressed gas cylinder.

in animals. Limited studies have shown the substance not to be a
carcinogen, or to exhibit mutagenic effects. Exposures up to 300000 ppm
and 40000 ppm did not produce teratogenic effects in rats and rabbits
respectively. The workplace environmental exposure level (WEEL),
recommended by the AIHA, is thought to be protective against cardiac

embryo/foetus is not yet possible because although data may indicate a trend,
they are not sufficient for a final evaluation.

The no-effect-level for dimethyl ether is somewhere between 2000 ppm
(rabbits) and 50,000 ppm (humans) with possible cardiac sensitisation
occurring around 200,000 ppm (dogs). The AIHA has adopted a safety factor
of 100 in respect to the 50,000 ppm level in its recommendation for a
workplace environmental exposure level (WEEL) which is thought to protect
against both narcotic and sensitising effects. This level is consistent
with the TLV-TWA of 400 ppm for diethyl ether and should be easily
achievable using current technologies. The use of the traditionally
allowable excursion of 1.25 to the level of 6.25 ppm is felt to be more
than adequate as an upper safe limit of exposure.
Human data:
50,000 ppm (12 mins): Feelings of mild intoxication.
75,000 ppm (12 mins): As above plus slight lack of attenuation.
82,000 ppm (12 mins): Some incoordination, slight blurring of vision

ENGINEERING CONTROLS
General exhaust is adequate under normal conditions. If risk of overexposure
exists, wear SAA 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: Speed:
aerosols, (released at low velocity 0.5-1 m/s
into zone of active generation)
direct spray, spray painting in shallow 1-2.5 m/s (200-500 f/min.)
booths, gas discharge (active
generation into zone of 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.

Section 11 - TOXICOLOGICAL INFORMATION
In common with other halogenated aliphatics, fluorocarbons may cause dermal
problems due to a tendency to remove natural oils from the skin causing
irritation and the development of dry, sensitive skin. They do not appear to be
appreciably absorbed.
Alkyl ethers may defat and dehydrate the skin producing dermatoses. Absorption
may produce headache, dizziness, and central nervous system depression.
INHALED
Inhalation of aerosols (mists, fumes), generated by the material during the
course of normal handling, may be harmful.
Material is highly volatile and may quickly form a concentrated atmosphere in
confined or unventilated areas. Vapour is heavier than air and may displace and
replace air in breathing zone, acting as a simple asphyxiant. This may happen
with little warning of overexposure.
WARNING:Intentional misuse by concentrating/inhaling contents may be lethal.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are by accidental skin and eye contact and by inhalation of
vapours especially at higher temperatures. Persons with a history of asthma or other
respiratory problems or are known to be sensitised, should not be engaged in any work
involving the handling of isocyanates. [CCTRADE-Bayer, APMF]. A 90-day inhalation study in
rats with polymeric MDI (6 hours/day, 5 days/week) produced moderate to severe
hyperplastic inflammatory lesions in the nasal cavities and lungs at levels of 8 mg/m3 or
greater. Practical evidence shows that inhalation of the material is capable of inducing a
sensitisation reaction in a substantial number of individuals at a greater frequency than
would be expected from the response of a normal population. Pulmonary sensitisation,
resulting in hyperactive airway dysfunction and pulmonary allergy may be accompanied by
fatigue, malaise and aching. Significant symptoms of exposure may persist for extended
periods, even after exposure ceases. Symptoms can be activated by a variety of nonspecific
environmental stimuli such as automobile exhaust, perfumes and passive smoking. Practical
experience shows that skin contact with the material is capable either of inducing a
sensitisation reaction in a substantial number of individuals, and/or of producing a
positive response in experimental animals. Respiratory sensitisation may result in
allergic/asthma like responses; from coughing and minor breathing difficulties to
bronchitis with wheezing, gasping. Sensitisation may result in allergic dermatitis
responses including rash, itching, hives or swelling of extremities. Isocyanate
vapours/mists are irritating to the upper respiratory tract and lungs; the response may be
severe enough to produce bronchitis with wheezing, gasping and severe distress, even
sudden loss of consciousness, and pulmonary oedema. Possible neurological symptoms arising
from isocyanate exposure include headache, insomnia, euphoria, ataxia, anxiety neurosis,
depression and paranoia. Gastrointestinal disturbances are characterised by nausea and
vomiting. Pulmonary sensitisation may produce asthmatic reactions ranging from minor
breathing difficulties to severe allergic attacks; this may occur following a single acute
exposure or may develop without warning after a period of tolerance. A respiratory
response may occur following minor skin contact. Skin sensitisation is possible and may
result in allergic dermatitis responses including rash, itching, hives and swelling of
extremities. Isocyanate-containing vapours/ mists may cause inflammation of eyes and nasal
passages. Onset of symptoms may be immediate or delayed for several hours after exposure.
Sensitised people can react to very low levels of airborne isocyanates. Unprotected or
sensitised persons should not be allowed to work in situations allowing exposure to this
material. WARNING: Aerosol containers may present pressure related hazards.
