Abstract
In response to a request from the United Auto Workers, Local 437, an evaluation was made of possible hazardous exposures to dusts containing silica (7631869) and other toxic compounds at L.R.I. Industries, Chelsea, Michigan. This facility manufactures ceramic tumbling media for mass finishing of metal parts. General area and personal breathing samples were taken in all areas where dust could settle or be generated. The batchware operator, special refractory operator, and the pug mill operator were slightly overexposed to respirable free silica. All noise measurements taken exceeded the NIOSH recommended levels of 85 decibels-A (dBA) for an 8 hour workday and the OSHA standard of 90dBA. The author concludes that hazards existed from exposure to noise, free silica and unsanitary eating conditions at this facility. The author recommends that the exhaust ventilation system for the batchware operator be redesigned so as to reduce dust exposure. Housekeeping throughout the facility should be improved, and worn gaskets around duct work should be repaired or replaced. Engineering controls should be utilized to reduce noise in inspection and pug mill areas. The pug mill machine should have rubber gaskets and mufflers installed. The salvage machine has already been isolated from the workers. Medical surveillance should be upgraded. NIOSH approved respirators should be used. An eating facility should be established which is separate from the factory area.
