TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN! AVOID EXPOSURE OF BREASTFEEDING WOMEN!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Incoordination. Headache. Tremor. Weakness.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED!  Protective clothing. Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes   Wear face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion See Inhalation.  Do not eat, drink, or smoke during work. Wash hands before eating.  Induce vomiting (ONLY IN CONSCIOUS PERSONS!). See Notes. Give a slurry of activated charcoal in water to drink. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALS. 

Physical dangers
 

Chemical dangers
On combustion, forms chlorine fumes and hydrogen chloride. Decomposes on contact with acids. This produces toxic fumes. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Carcinogen category: 3B; (DFG 2002). 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of short-term exposure
The substance may cause effects on the central nervous system and liver. This may result in impaired functions and liver impairment. The effects may be delayed. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the endocrine system. This substance is possibly carcinogenic to humans. Causes toxicity to human reproduction or development. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Sublimation point: 350°C (decomposes)
Solubility in water at 20°C: poor
Octanol/water partition coefficient as log Pow: 3.45  
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish, mammals and milk. 

NOTES
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Do NOT take working clothes home.
Consult national legislation.
