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

 PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes   Wear safety spectacles.  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. Wash hands before eating.  Rinse mouth. Rest. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Do NOT wash away into sewer. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Personal protection: self-contained breathing apparatus.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
 

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. 

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


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to algae and aquatic plants. 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
If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s).
Carrier solvents used in commercial formulations may change physical and toxicological properties.
