Control Technology Assessment of Petroleum Refinery Operations: Indepth Site Visit Report, Chevron El Segundo Refinery

摘要

Exposure control techniques associated with petroleum refining operations were identified during a site visit to Chevron U.S.A.'s El Segundo Refinery (SIC-2911) in El Segundo, California in May, 1982. The exposure controls studied were the process sample collection systems, hydrogen-sulfide (HS) monitoring systems, catalyst dust wet scrubbers, covered dissolved air flotation tanks, and safety programs. Systems were designed to significantly reduce the potential for worker exposure to toxic chemicals by venting gases away from operators while shielding them from spilled material. The HS monitoring system utilized a sensing unit, a controller unit, and an alarm to warn workers when higher than ambient concentrations were present. The authors conclude that the refinery's extensive use of safety signs, curb pavement markings, safety equipment, and an active safety training program are good examples of effective administrative safety and health controls.
