EXPOSURE See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE.
AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN!

Inhalation
Local exhaust or breathing protection.
Fresh air, rest.
Skin MAY BE ABSORBED!
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap.

BENZO(a)PYRENE ICSC: 0104
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
PALE-YELLOW CRYSTALS

CHEMICAL DANGERS:
Reacts with strong oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: Exposure by all routes should be carefully controlled to levels as low as possible A2 (suspected human carcinogen); (ACGIH 2005).
MAK: Carcinogen category: 2; Germ cell mutagen group: 2; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
This substance is carcinogenic to humans. May cause heritable genetic damage to human germ cells. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
PHYSICAL PROPERTIES
Boiling point: 496C
Melting point: 178.1C
Density: 1.4 g/cm
Solubility in water: none (<0.1 g/100 ml)
Vapour pressure : negligible
Octanol/water partition coefficient as log Pow: 6.04
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish, in plants and in molluscs. The substance may cause long-term effects in the aquatic environment.
NOTES
Do NOT take working clothes home. 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.
