  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

 AVOID ALL CONTACT! AVOID EXPOSURE OF BREASTFEEDING WOMEN! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
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.

Molecular mass: 490.6
Sublimation point: 350°C (decomposes)
Solubility in water at 20°C: poor
Octanol/water partition coefficient as log Pow: 3.45  


EXPOSURE & HEALTH EFFECTS

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

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. 

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
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. 


OCCUPATIONAL EXPOSURE LIMITS
MAK: skin absorption (H); carcinogen category: 2 

ENVIRONMENT
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.
