Industrial Hygiene Walk-Through Survey at Shell Oil Company Refinery, Odessa, Texas

摘要

Worker exposures to carbon-monoxide (630080), hydrogen-sulfide (7783064), and benzene (71432) were surveyed at the Shell Oil Company Refinery (SIC-2911) in Odessa, Texas on December 19 and 20, 1978. The facility was surveyed as part of a NIOSH study of the industrial hygiene characteristics of petroleum refineries. Approximately 100 of the employees at the facility were assigned to the production areas surveyed. All employees received preplacement medical examination and periodic medical examinations. Air samples for carbon-monoxide, hydrogen-sulfide, and benzene ranged from 1 to 10, 1 to 5, and 1 to 5 parts per million, respectively. No detectable concentrations of nitrogen-dioxide, ammonia, or aromatic amines were found. The author notes that data provided by this survey allowed development of a survey protocol which reduced the scope of the NIOSH petroleum refinery study to three key types of process units; the fluid catalytic cracker unit, the delayed coker unit, and the asphalt processing unit.
