  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

See Notes. AVOID ALL CONTACT! PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation   Use closed system and ventilation.  Fresh air, rest. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles or eye protection in combination with breathing protection.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Do NOT wash away into sewer. Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. 

According to UN GHS Criteria

EXPOSURE & HEALTH EFFECTS

Routes of exposure
Exposure mainly occurs via inhalation. 

Effects of short-term exposure
See Notes. 

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

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. This substance is carcinogenic to humans. May cause heritable genetic damage to human germ cells. May cause toxicity to human reproduction or development. 


Occupational exposure limits
TLV: A2 (suspected human carcinogen); BEI issued.
MAK: skin absorption (H); carcinogen category: 2; germ cell mutagen group: 2 

ENVIRONMENT
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish, plants and molluscs. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Do NOT take working clothes home.
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
Benzo(a)pyrene is present as a component of polycyclic aromatic hydrocarbons (PAHs) in the environment, usually resulting from the incomplete combustion or pyrolysis of organic matters, especially fossil fuels and tobacco.
