OCCUPATIONAL EXPOSURE OF DECK CREWS TO CARCINOGENIC AGENTS ON CRUDE-OIL TANKERS

Occupational exposure to carcinogenic agents on the decks on six Norwe gian crude oil tankers was examined in five harbors. The purpose of th e study was to evaluate the need for improving the working environment on deck on these tankers. Technical arrangements and the work itself on the deck were observed during loading or unloading. Occupational mo nitoring was performed by active sampling of benzene, polyaromatic hyd rocarbons, and some aldehydes. The crew answered a questionnaire conce rning their work, use of protective equipment, and occurrence of acute symptoms. The levels of air-borne carcinogenic agents were low, proba bly due to closed loading systems on all tankers. However, the seamen reported discomfort during the work that may be related to other chemi cal agents in the cargo. The seamen were frequently painting with lead chromate paint without using personal protective equipment. This type of chemical exposure should be evaluated. (C) 1995 Wiley-Liss, Inc.
