| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Extremely flammable. Explosive.
|
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. Do NOT expose to friction or shock.
|
In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
|
| EXPOSURE |
|
AVOID ALL CONTACT!
|
IN ALL CASES CONSULT A DOCTOR!
|
| Inhalation |
Abdominal pain. Confusion. Dizziness. Headache. Nausea. Shortness of breath. Vomiting. Weakness. Symptoms may be delayed (see Notes).
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest. 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, or eye protection in combination with breathing protection.
|
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.
|

| IMPORTANT DATA | |||
|
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. CHEMICAL DANGERS: The substance decomposes on heating and under the influence of light and moisture producing toxic arsenic fumes. Reacts with strong oxidants, causing explosion hazard. May explosively decompose on shock, friction, or concussion. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.05 ppm as TWA; Intended change( TLV: 0.005 ppm A4 (not classifiable as a human carcinogen);) (ACGIH 2005). MAK: IIb (not established but data is available) (DFG 2007). |
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: Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the blood , resulting in destruction of blood cells and kidney failure. The effects may be delayed. Exposure may result in death. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: This substance is carcinogenic to humans. | ||

| ENVIRONMENTAL DATA | |||
|
It is strongly advised that this substance does not enter the environment.
| |||
| NOTES | |||
|
The symptoms of poisoning do not become manifest until a few hours or even a few days have passed. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state. Also consult ICSC 0013 Arsenic. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
