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      
 
EXPOSURE See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE.     
Inhalation Cough.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. 
Skin MAY BE ABSORBED!  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.  Do not transport with food and feedstuffs.

EMERGENCY RESPONSE SAFE STORAGE
  Provision to contain effluent from fire extinguishing. Separated from oxidants and food and feedstuffs. Store in an area without drain or sewer access. 

IMPORTANT DATA
Physical State; Appearance
WHITE-TO-OFF-WHITE CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride. Reacts violently with oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation, through the skin and by ingestion. 

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

Effects of short-term exposure
 

Effects of long-term or repeated exposure
The substance may have effects on the skin. This may result in chloracne.
