Environmental and medical survey of operations and personnel in a plant manufacturing porcelain enamel coated steel bath tubs (SIC- 3431), involving the application of ground and finish coats by electrostatic spraying which exposes men to silica (7631869). Data are given for the components of ground coat, white cover coat, and bulk samples, and also for personnel sample, industrial ventilation, and inspection and cleaning of respirators. Analysis of the bulk and personnel samples indicates that finish coats contain, on an average, less than 1 percent free silica, that the ground coat contains about 5 percent free silica, and that exposure to respirable free silica at the ground coat spray area is about three times the recommended maximum of 1.4 milligrams per cubic meter. Recommendations include increasing ground coat spray booth exhaust ventilation to about 125 feet per minute face velocity, removal of the fan located at the exit end of the ground coat booth, training of operatives, preemployment and routine chest x-rays, and other medical checkups, provision of lockers, showers, and drinking fountains, and establishment of personal protection plans and safety programs.
