PHYSICAL DANGERS:


CHEMICAL DANGERS:


OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
See Notes.

PHYSICAL
PROPERTIES

Boiling point: 399°C
Melting point: 189°C
Solubility in water: very poor
Octanol/water partition coefficient as log Pow: 5.32

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms.

N O T E S

This substance does not usually occur as a pure substance but as a component of polyaromatic hydrocarbon (PAH) mixtures. Human population studies have associated PAH's exposure with cancer and cardiovascular diseases. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Do NOT take working clothes home.
