Exposure of the deck crew to carcinogenic agents on oil product tankers.
Work on deck on eight oil product tankers was examined. The purpose was to evaluate the need for improvement of the working environment to reduce the risk of occupational cancer. Benzene, polyaromatic hydrocarbons (PAHs) and organic lead compounds were sampled, and the crew answered a questionnaire on acute health effects. By area monitoring, benzene was generally found to be in the range from the detection limit, of 0.01 ppm, up to 1.15 ppm, but one tanker which loaded gasoline with the hatches open had levels up to 55 ppm. Personal monitoring showed exposure levels in the range 0.01-1.15 ppm. The PAH-levels and the levels of organic lead were low. No seamen were observed using respiratory protective equipment. Central nervous system symptoms were reported by the crew with the highest exposures to benzene although benzene may not be the only cause. The exposure to benzene and other hydrocarbons on the deck of oil product tankers ought to be reduced.
