Molecular mass: 236.7
CAS # 67-72-1
RTECS # KI4025000
ICSC # 0051

TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Not combustible. Gives off toxic and corrosive vapours in a fire.		In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION			In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT DISPERSION OF DUST! PREVENT GENERATION OF MISTS!
INHALATION		Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
SKIN	MAY BE ABSORBED!	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
EYES		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.	Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating above 300°C producing toxic and corrosive fumes, phosgene (see ICSC # 0007) and hydrogen chloride (see ICSC # 0163). Reacts violently with zinc, aluminium powder and sodium. Attacks iron in the presence of moisture.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 1 ppm; 9.7 mg/m³ skin (ACGIH 1992-1993).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
Exposure could cause unconsciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the liver and kidneys. Exposure at far above the OEL may have effects on the central nervous system, inducing tremors and ataxia.
