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 Irregular heartbeat. Confusion. Drowsiness. Unconciousness.  Use 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.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.

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 lowered spaces causing a deficiency of oxygen. 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive gases of hydrogen chloride (see ICSC 0163), phosgene (see ICSC 0007), hydrogen fluoride (see ICSC 0283) and carbonyl fluoride (see ICSC 0633). Reacts with powdered aluminium, powdered zinc, magnesium shavings, lithium shavings and granular barium. 

Occupational exposure limits
TLV: 1000ppm (ceiling value); A4 (not classifiable as a human carcinogen); (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 substance can cause suffocation by lowering the oxygen content of the air 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. This may result 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/100ml 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

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.
