TO BROWN
PASTE
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating above 400°C
producing
toxic fumes
.
Reacts
with
strong oxidants
.
Occupational Exposure Limits:
TLV: (as benzene soluble aerosol for coal tar pitch volatiles) 0.2 mg/m3 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 20°C 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.
