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.
•INGESTION

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).
OSHA PEL: TWA 0.1 ppm (0.5 mg/m3)
NIOSH REL: TWA 0.1 ppm (0.5 mg/m3)
NIOSH IDLH: 5 ppm See: 7803523


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.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: -18°C
Melting point: -88°C
Relative density (water = 1): 2.26 at -25°C
Solubility in water: poor
Relative vapour density (air = 1): 4.4
Flash point: Flammable Gas

ENVIRONMENTAL
DATA


N O T E S

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.
Transport Emergency Card: TEC (R)-20GT2TF
