TYPES OF
HAZARD /
EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING

FIRE Not combustible. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.

EXPLOSION

In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.

EXPOSURE

Inhalation Drowsiness. Unconsciousness.
Ventilation.
Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.

Skin ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.

Eyes ON CONTACT WITH LIQUID: FROSTBITE.
Face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.

Ingestion

SPILLAGE DISPOSAL PACKAGING & LABELLING

Ventilation. Do NOT let this chemical enter the environment.
UN Hazard Class: 2.2

EMERGENCY RESPONSE STORAGE

Transport Emergency Card: TEC (R)-20G39
Fireproof if in building.

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
LIQUEFIED COMPRESSED GAS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The gas is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen.

CHEMICAL DANGERS:
The substance decomposes on contact with open flames or very hot surfaces, producing toxic gases including phosgene, hydrogen fluoride, hydrogen chloride, hydrogen bromide.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
On loss of containment this liquid evaporates very quickly causing supersaturation of the air with serious risk of suffocation when in confined areas.

EFFECTS OF SHORT-TERM EXPOSURE:
Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the cardiovascular system , resulting in cardiac disorders.

PHYSICAL PROPERTIES

Boiling point: -4�C
Melting point: -160.5�C
Solubility in water: none
Relative vapour density (air = 1): 5.7
Octanol/water partition coefficient as log Pow: 2.1

ENVIRONMENTAL DATA

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. Do NOT use in the vicinity of a fire or a hot surface, or during welding.
