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 water spray, 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: keep cylinder cool by spraying with water.

EXPOSURE		AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN!
•INHALATION	Cough. Sore throat. Dizziness. Headache. Drowsiness. Blurred vision. Nausea. Unconsciousness.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. 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	Redness. Pain. Blurred vision. See Skin.	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.

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

PHYSICAL DANGERS:
The gas is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated. The vapours are uninhibited and may form polymers in vents or flame arresters of storage tanks, resulting in blockage of vents.

CHEMICAL DANGERS:
The substance can under specific circumstances (exposure to air) form peroxides, initiating explosive polymerization. The substance may polymerize due to warming with fire or explosion hazard. Shock-sensitive compounds are formed with copper and its alloys (see Notes). The substance decomposes explosively on rapid heating under pressure. Reacts vigorously with oxidants and many other substances, causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA; A2 (suspected human carcinogen); (ACGIH 2004).
MAK:
Carcinogen category: 1; Germ cell mutagen group: 2;
(DFG 2004).
OSHA PEL: 1910.1051 TWA 1 ppm ST 5 ppm
NIOSH REL: Ca See Appendix A
NIOSH IDLH: Potential occupational carcinogen 2000 ppm LEL

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes and the respiratory tract. Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system , resulting in lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the bone marrow , resulting in leukemia. This substance is probably carcinogenic to humans. May cause heritable genetic damage in humans. Animal tests show that this substance possibly causes toxic effects upon human reproduction.

ENVIRONMENTAL
DATA

N O T E S

Piping material for this gas must not contain over 63% of copper. Use of alcoholic beverages enhances the harmful effect. The odour warning when the exposure limit value is exceeded is insufficient. Card has been partly updated in October 2004 and April 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
