Personal exposure to benzene and 1,3-butadiene during petroleum refinery turnarounds and work in the oil harbour

Abstract

Work within the petroleum refinery industry, with potential exposure to open product streams containing higher fractions of benzene, pose a risk of personal benzene exposures exceeding the OEL. Refinery workers performing these work tasks frequently, such as contractors, sewage tanker drivers and oil harbour workers, need to be identified and protected.
