TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT DISPERSION OF DUST! PREVENT GENERATION OF MISTS!   
Inhalation Cough.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .

EMERGENCY RESPONSE SAFE STORAGE
  Separated from strong oxidants, alkali metals and food and feedstuffs. See Chemical Dangers. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes above 300°C . This produces toxic and corrosive fumes of phosgene (see ICSC 0007) and hydrogen chloride (see ICSC 0163). Reacts with zinc, aluminium powder and sodium. Reacts violently with alkali metals and strong oxidants. 

Occupational exposure limits
TLV: 1ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2010).
MAK: 1 ppm, 9.8 mg/m³; Peak limitation category: II(2); (DFG 2010). 

Routes of exposure
The substance can be absorbed into the body by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
The vapour is irritating to the eyes. 

Effects of long-term or repeated exposure
The substance may have effects on the liver and kidneys. The substance may have effects on the central nervous system. This may result in ataxia and tremors. Tumours have been detected in experimental animals but may not be relevant to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Sublimation point: 183-185°C
Relative density (water = 1): 2.1
Solubility in water: none
Vapour pressure, Pa at 20°C: 53
Relative vapour density (air = 1): 8.2
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0
Octanol/water partition coefficient as log Pow: 3.9  
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. 

NOTES
Use of alcoholic beverages enhances the harmful effect.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
