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.	In case of fire: cool cylinder by spraying with water but avoid contact of the substance with water. Combat fire from a sheltered position.

EXPOSURE
Inhalation	Drowsiness. Suffocation (see Notes).	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	See Skin.	Safety goggles or face shield.	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
Evacuate danger area! Consult an expert! Ventilation. Remove all ignition sources. NEVER direct water jet on liquid. Chemical protection suit including self-contained breathing apparatus.	EU classification F+ Symbol R: 12 S: (2-)9-16-33 UN classification UN Hazard Class: 2.1

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-137. NFPA Code: H1; F4; R1.	Fireproof. Cool.

IMPORTANT DATA

Physical State; Appearance
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
Reacts violently with oxidants causing fire and explosion hazard.

Occupational exposure limits
TLV: Simple asphyxiant A4 (not classifiable as a human carcinogen); Intended change (ACGIH 2005).
MAK not established.

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

Inhalation risk
On loss of containment this gas can cause suffocation by lowering the oxygen content of the air 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. Exposure could cause lowering of consciousness. See Notes.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: -48°C Melting point: -185°C Relative density (water = 1): 0.5 Solubility in water: poor Vapour pressure, kPa at 25°C: 1158 Relative vapour density (air = 1): 1.5 Flash point: Flammable Gas Auto-ignition temperature: 460°C Explosive limits, vol% in air: 2.4-10.3 Octanol/water partition coefficient as log Pow: 1.77

NOTES

High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
Check oxygen content before entering area.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Card has been partially updated in August 2007: see Occupational Exposure Limits.
