  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, dry powder, foam, carbon dioxide.   

See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE. AVOID ALL CONTACT!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation No acute symptoms expected.  Use closed system or ventilation.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED!  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety goggles, face shield or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
 

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

Effects of long-term or repeated exposure
The substance may have effects on the bladder. This may result in inflammation and tissue lesions. This substance is carcinogenic to humans. See Notes.

MAK: skin absorption (H); carcinogen category: 1; germ cell mutagen group: 3A 

ENVIRONMENT
Environmental effects from the substance have not been investigated adequately. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Special attention should be given to urine sediment and cytology.
Special attention should be given to blood in urine.
