NIOSH 1977 Sep:9 pages
A Health Hazard Evaluation investigation was conducted by NIOSH on April 5-7, 1977, at the Union 76 Oil Refinery (SIC-2911) near Nederland, Texas. The survey was prompted by a request from representative of the approximately 700 affected employees who were thought to be exposed to a variety of chemical fumes. Environmental sampling for benzene (71432), toluene (108883), xylene (1330207), cyclohexane (110827), methyl-ethyl-ketone (78933), hexane (110543), heptane (142825), ammonia (7664417), sulfuric-acid (7664939), and sodium-hydroxide (1310732) indicated that the employees were not exposed to potentially toxic concentrations of these materials. However, several of the samples analyzed for benzene were near the exposure limit recommended by NIOSH. For this reason, continued monitoring of atmospheric contaminants, particularly benzene, is recommended.
