  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.    NO open flames.    Use water spray, foam, powder, carbon dioxide.   

 PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the eyes and respiratory tract. 

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

Effects of long-term or repeated exposure
The substance may have effects on the testes. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


Occupational exposure limits
TLV: 5 mg/m3, ppm, as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans).
MAK: (inhalable fraction): 2 mg/m3; peak limitation category: II(2); skin absorption (H); carcinogen category: 4; pregnancy risk group: C 

ENVIRONMENT
Bioaccumulation of this chemical may occur in seafood.
