| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Extremely flammable. Gives off irritating or toxic fumes (or gases) in a fire.
|
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.
|
| EXPLOSION |
Gas/air mixtures are explosive. Risk of fire and explosion on contact with ozone or concentrated nitric acid.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting.
|
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 |
Cough. Sore throat. Headache. Weakness. Laboured breathing. Nausea. Weak, slow and irregular pulse. Hemoglobinuria.
|
Closed system and ventilation.
|
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.
|
| Skin |
ON CONTACT WITH LIQUID: FROSTBITE.
|
Cold-insulating gloves.
|
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer immediately for medical attention.
|
| Eyes |
Redness.
|
Eye protection in combination with breathing protection.
|
First rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS COMPRESSED GAS , WITH PUNGENT ODOUR. PHYSICAL DANGERS: The gas is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance decomposes slowly at room temperature but quickly at 200°C producing metallic antimony and hydrogen , which increases fire hazard. Reacts violently with chlorine, concentrated nitric acid and ozone causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.1 mg/m³ (as TWA) (ACGIH 2007). 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 is severely irritating to the respiratory tract. The substance may cause effects on the blood , resulting in destruction of blood cells. Exposure above the OEL may result in death. Medical observation is indicated. | ||

| ENVIRONMENTAL DATA | |||
|
| |||
| NOTES | |||
|
Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61°C. Depending on the degree of exposure, periodic medical examination is indicated. The relation between odour and the occupational exposure limit cannot be indicated.
