Not considered a normal route of entry.
· 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 unconscious.
· Give water to rinse out mouth, then provide liquid slowly and as much as
casualty can comfortably drink.
· Seek medical advice.
If aerosols come in contact with the eyes:
· Immediately hold the eyelids apart and flush the eye with fresh 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.
· If pain persists or recurs seek medical attention.
· Removal of contact lenses after an eye injury should only be undertaken by
skilled personnel.
If solids or aerosol mists are deposited upon the skin:
· Flush skin and hair with running water (and soap if available).
· Remove any adhering solids with industrial skin cleansing cream.
· DO NOT use solvents.
· Seek medical attention in the event of irritation.
If aerosols, fumes or combustion products are inhaled:
· Remove to fresh air.
· 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.
· 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.
· Transport to hospital, or doctor.
Treat symptomatically.

From IERG (Canada/Australia) Isolation Distance - Downwind Protection Distance 8 metres IERG Number 49
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. 5 Guide 126 is taken from the US DOT emergency response guide book. 6 IERG information is derived from CANUTEC - Transport Canada.

Composite Exposure Standard for Mixture (TWA) (mg/m³): 4240 mg/m³

exceeded, "Worst Case" considerations deem the individual to be overexposed.

TETRAFLUOROETHANE: ES TWA: 1000 ppm, 4240 mg/m³ OES TWA: 1000 ppm, 4240 mg/m³ Studies show that HFC 134a is practically nontoxic by inhalation. The acute lethal effects occur at levels exceeding 500000 ppm whilst the threshold for cardiac sensitisation occurs at about 75000 ppm. Repeated exposures at 50000 ppm for 13 weeks did not produce significant toxicity 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 sensitisation and systemic injury. 1,1-DIFLUOROETHANE: No exposure limits set by NOHSC or ACGIH WEEL TWA (8hr): 1000 ppm CEL-Hungary TWA: 200 mg/m³; STEL: 500 mg/m³
No special equipment for minor exposure i.e. when handling small quantities. OTHERWISE: For potentially moderate or heavy exposures: · Safety glasses with side shields. · NOTE: Contact lenses pose a special hazard; soft lenses may absorb irritants and ALL lenses concentrate them.
No special equipment needed when handling small quantities. OTHERWISE: For potentially moderate exposures: Wear general protective gloves, eg. light weight rubber gloves. For potentially heavy exposures: Wear chemical protective gloves, eg. PVC. and safety footwear.
No special equipment needed when handling small quantities. OTHERWISE: · Overalls. · Skin cleansing cream. · Eyewash unit. · Do not spray on hot surfaces.
Respiratory protection may be required when ANY "Worst Case" vapour-phase
concentration is exceeded (see Computer Prediction in "Exposure Standards").

· Elevated temperatures.
· Presence of open flame.
· Product is considered stable.
· Hazardous polymerisation will not occur.
Overexposure is unlikely in this form.
Not normally a hazard due to physical form of product.
Considered an unlikely route of entry in commercial/industrial environments
The liquid is harmful if swallowed and capable of causing severe cold burns.
Although the liquid is not thought to be an irritant (as classified by EC
Directives), direct contact with the eye may produce transient discomfort
characterised by tearing or conjunctival redness (as with windburn).
The liquid is capable of causing severe cold burns.
Spray mist may produce discomfort.
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.
Vapourising liquid causes rapid cooling and contact may cause cold burns,
frostbite.
Inhalation hazard is increased at higher temperatures.
WARNING:Intentional misuse by concentrating/inhaling contents may be lethal.
Inhalation of vapours may cause drowsiness and dizziness. This may be
accompanied by narcosis, drowsiness, reduced alertness, loss of reflexes, lack
of coordination and vertigo.
Principal routes of exposure are by accidental skin and eye contact and by inhalation of
vapours especially at higher temperatures. It is generally accepted that the fluorocarbons
are less toxic than the corresponding halogenated aliphatic based on chlorine. Repeated
inhalation exposure to the fluorocarbon FC-11 does not produce pathologic lesions of the
liver and other visceral organs in experimental animals. There has been conjecture in
non-scientific publications that fluorocarbons may cause leukemia, cancer, sterility and
birth defects; these have not been verified by current research. The high incidence of
cancer, spontaneous abortion and congenital anomalies amongst hospital personnel,
repeatedly exposed to fluorine-containing general anaesthetics, has caused some scientists
to call for a lowering of the fluorocarbon exposure standard to 5 ppm since some are
mutagens. WARNING: Aerosol containers may present pressure related hazards.
