  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible under specific conditions. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion if formulations contain flammable/explosive solvents.  NO open flames.    Use water spray, foam, powder, carbon dioxide.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation   Use ventilation (not if powder).  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety spectacles.  Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention .

EXPOSURE & HEALTH EFFECTS

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

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

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

Effects of long-term or repeated exposure
The substance may have effects on the liver. This may result in tissue lesions. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 2 mg/m3, as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans).
MAK: 1 mg/m3; peak limitation category: II(2); pregnancy risk group: C 

ENVIRONMENT
The substance is toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal. 

NOTES
Temperature of decomposition is unknown in the literature.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
If the substance is formulated with solvents also consult the ICSCs of these materials.
