Coke oven contain cancer-causing polynuclear
aromatic hydrocarbons, along with toxic
gases and vapours such as
benzene, hydrogen sulphide, carbon monoxide
and ammonia.
Workers in the coal preparation plant are
exposed to coal dust, which can cause lung
damage.
Short-term (acute) inhalation causes
depression of the central nervous system,
marked by drowsiness, dizziness, headache,
nausea, loss of coordination, confusion and
unconsciousness. Long-term exposure
to benzene reduces the number of red and
white blood cells and damages bone marrow.
Benzene is carcinogenic.
Inhalation of carbon monoxide causes
symptoms including headache, weakness,
dizziness, nausea, fainting, increased
heartbeat, irregular heartbeat, loss of
consciousness and death.
Short-term (acute) inhalation causes severe
irritation of the respiratory tract. Skin contact
results in burns, blistering and, possibly,
permanent scarring of the skin. Eye contact
causes irritation and, possibly, corrosive
injury.
