The chronic exposure to very low concentration of benzene vapor in air of the order of a few parts per million may cause cancer. In order to protect the health of crews to the same level as that of shore-based workers performing compatible tasks, it is necessary to reduce operational exposure to benzene vapor. Personal exposure levels of crews to benzene vapor during marine benzene transfer operations were measured. The tests were conducted during routine operations and loading, transit, unloading and tank cleaning operations of benzene tankers. The vapor samples were collected in the passive sampler and were subsequently analized by the gas chromatography. The measured personal exposure levels vary with operation and person, and the highest level occurs during tank cleaning operation. The middle point of the time averaged level of all data points was estimated to approximately same as operational exposure limits. The health risk of crews associated with exposure to benzene vapor is quantitatively assessed. The method for reducing risk of health for crews is suggested.
