Abstract
Environmental and medical surveys were conducted on November 8, 1978, and July 19 and 20, 1979, to evaluate employee exposure to methylene-chloride (75092), methyl-ethyl-ketone (78933), styrene (100425), fibrous glass, silica (7631869) and nuisance particulate matter at the Owens Corning Fiberglas Corporation in Conroe, Texas. (SIC-2221) The evaluation was requested by an authorized representative of the United Paperworkers International Union on behalf of the approximately 157 affected workers. All of the environmental air samples were well below current OSHA standards. Methylene-chloride concentrations ranged from 18 to 85 milligrams per cubic meter (mg/m3), below the OSHA standard of 1750mg/m3; methyl-ethyl-ketone ranged from 4 to 20mg/m3, below the OSHA standard of 590mg/m3; styrene ranged from 65 to 200mg/m3, below the OSHA standard of 420mg/m3; fibrous glass concentrations were less than 0.01 fibers per cubic centimeter, below the NIOSH standard of 3.0 fibers per cubic centimeter; silica (quartz/cristobalite) ranged from undetectable to 0.33mg/m3, below the OSHA standard of 30mg/m3; and nuisance particulate matter ranged from 0.3 to 4.7mg/m3, below the OSHA standard of 15mg/m3. The author concludes that no hazardous exposures existed at the time of the evaluation. He recommends that fibrous glass and styrene workers have preplacement medical examinations.
