COAL-TAR PITCH ICSC: 1415
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
BLACK TO BROWN PASTE

CHEMICAL DANGERS:
The substance decomposes on heating above 400C producing toxic fumes. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as benzene soluble aerosol for coal tar pitch volatiles) 0.2 mg/m as TWA A1 (ACGIH 2001).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and 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 and when heated.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. Exposure to sun may enhance the irritating effect of coal tar pitch on skin and eyes and lead to burns.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis and hyperpigmentation of skin. This substance is carcinogenic to humans.
PHYSICAL PROPERTIES
Boiling point: >250C
Melting point: 30-180C
Density: >1 g/cm^3
Solubility in water: at 20C none
Vapour pressure, kPa at 20C: <0.01
Flash point: >200C o.c.
Auto-ignition temperature: >500C
Octanol/water partition coefficient as log Pow: 6.04
ENVIRONMENTAL DATA
This substance may be hazardous to the environment; special attention should be given to soil contamination and aquatic organisms. The substance may cause long-term effects in the aquatic environment.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
