TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION			In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE
Inhalation	Cardiac arrhythmia. Confusion. Drowsiness. Unconsciousness.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin	ON CONTACT WITH LIQUID: FROSTBITE. Dry skin.	Cold-insulating gloves.	ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
Eyes	Redness. Pain.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion		Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Ventilation.

EMERGENCY RESPONSE	SAFE STORAGE
	Separated from incompatible materials. See Chemical Dangers. Cool.

IMPORTANT DATA

Physical State; Appearance
COLOURLESS GAS OR HIGHLY VOLATILE LIQUID, WITH CHARACTERISTIC ODOUR.

Physical dangers
The gas is heavier than air. The vapour is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen.

Chemical dangers
On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive gases (hydrogen chloride ICSC 0163, phosgene ICSC 0007, hydrogen fluoride ICSC 0283, carbonyl fluoride ICSC 0633). Reacts with powders of aluminium, zinc, magnesium and lithium shavings; granular barium.

Occupational exposure limits
TLV: 1000 ppm (Ceiling value); A4; (ACGIH 2004).
MAK: 1000 ppm; 5700 mg/m³; Peak limitation category: II(2); Pregnancy risk group: C; (DFG 2004).

Routes of exposure
The substance can be absorbed into the body by inhalation.

Inhalation risk
On loss of containment this liquid evaporates very quickly displacing the air and causing a serious risk of suffocation when in confined areas.

Effects of short-term exposure
The liquid may cause frostbite. The substance may cause effects on the cardiovascular system and central nervous system, resulting in cardiac disorders and central nervous system depression. Exposure could cause lowering of consciousness. See Notes.

Effects of long-term or repeated exposure
The liquid defats the skin.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 24°C Melting point: -111°C Relative density (water = 1): 1.49 Solubility in water, g/100 ml at 20°C: 0.1 Vapour pressure, kPa at 20°C: 89.0 Relative vapour density (air = 1): 4.7 Relative density of the vapour/air-mixture at 20°C (air = 1): 4.4 Octanol/water partition coefficient as log Pow: 2.53	This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer.

NOTES

High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
The occupational exposure limit value should not be exceeded during any part of the working exposure.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Freon 11, Frigen 11, Halon 11 are trade names.
Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
