TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Extremely flammable.	NO open flames, NO sparks, and NO smoking.	Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out; in other cases extinguish with powder, carbon dioxide .
EXPLOSION	Gas/air mixtures are explosive.	Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding) if in liquid state. Use non-sparking handtools.	In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.

EXPOSURE
•INHALATION	Drowsiness. Unconsciousness.	Closed system and ventilation.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
•SKIN	ON CONTACT WITH LIQUID: FROSTBITE.	Cold-insulating gloves. Protective clothing.	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

PHYSICAL STATE; APPEARANCE:
ODOURLESS, COLOURLESS COMPRESSED LIQUEFIED GAS.

PHYSICAL DANGERS:
The gas is heavier than air and may travel along the ground; distant ignition possible, and may accumulate in low ceiling spaces causing deficiency of oxygen. As a result of flow, agitation, etc., electrostatic charges can be generated.

CHEMICAL DANGERS:

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2500 ppm as TWA; (ACGIH 2003).
MAK: 1000 ppm, 1800 mg/mł;
Peak limitation category: II(2); Pregnancy risk group: IIc;
(DFG 2003).
OSHA PEL: TWA 1000 ppm (1800 mg/m³)
NIOSH REL: TWA 1000 ppm (1800 mg/m³)
NIOSH IDLH: 2100 ppm LEL

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:
Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: -42°C
Melting point: -189.7°C
Relative density (water = 1): 0.5
Solubility in water, g/100 ml at 20°C: 0.007
Vapour pressure, kPa at 20°C: 840

Relative vapour density (air = 1): 1.6
Flash point: -104°C
Auto-ignition temperature: 450°C
Explosive limits, vol% in air: 2.1-9.5
Octanol/water partition coefficient as log Pow: 2.36

ENVIRONMENTAL
DATA

N O T E S

Check oxygen content before entering area. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
