An evaluation of exposure of workers of the Midwest Steel Division of National Steel Corp. to organic solvents, acid mists, caustics, oil mists, asbestos and welding fumes during steel processing has been made. No basic steel is produced at this plant. Raw material in the form of hot rolled coils is received from other plants. The product is directed into one of three channels according to its intended use: 1) tin plate and tin free steel, 2) galvanized (SIC- 3312), or 3) cold rolled products (SIC-3316). The survey included over fifteen different areas or processes. Results of the personal and area samples were used to evaluate employee exposures. The personal samples were attached near the breathing zone of the employees to collect a representative sample of air. Atmospheric samples for particulate oil mist and for sulfuric-acid (7664939) were collected. Atmospheric samples for total dust, chromic-acid (7738945), and zinc-oxide (1314132) were collected on 5 microgram polyvinyl-chloride (9002862) (PVC) filters. Atmospheric samples for methyl-chloroform (71556) were collected on activated charcoal tubes. Atmospheric samples for carbon-monoxide (630080) were taken using Drager colorimetric gas detector tube units. Atmospheric samples for hydrogen cyanide (7408) were collected. An atmospheric sample for asbestos (1332214) was collected on an 0.8 microgram mixed cellulose ester filter at a flow rate of 2.01pm. Atmospheric samples for sodium-hydroxide (1310732) were collected with a fritted glass bubbler. An employee exposure to asbestos at the Deep Well exceeded both ceiling values of 0.5 fibers/cc and 10 fibers/cc respectively. All other samples were below the evaluation criteria.
