EXPOSURE
AVOID ALL CONTACT! PREVENT DISPERSION OF DUST!

 •INHALATION Sneezing. Cough. See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE.
Closed system and ventilation.
Fresh air, rest.
 •SKIN MAY BE ABSORBED! Redness. Burning sensation.
Protective gloves. Protective clothing.
Rinse and then wash skin with water and soap.
 •EYES Redness. Pain.
Safety goggles, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE.
Do not eat, drink, or smoke during work. Wash hands before eating.
Give plenty of water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
BLACK TO BROWN PASTE

PHYSICAL DANGERS:


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).
OSHA PEL: TWA 0.2 mg/m3 (benzene-soluble fraction) 1910.1002 See Appendix C
NIOSH REL: Ca TWA 0.1 mg/m3 (cyclohexane-extractable fraction) See Appendix A See Appendix C
NIOSH IDLH: Ca 80 mg/m3 See: 65996932


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.
