Worker exposure to airborne mineral fibers, total and respirable airborne particulate material, and trace metals was determined for plasterers employed by Frederick Meiswinkel, Incorporated, (SIC- 3479) in San Francisco, California, on July 13, 1977. No formal medical, industrial and safety programs existed. Medical examinations were given for pre-employment screening and to employees as needed. The use of personal protective respirators was optional. The fiber concentrations for worker breathing zone samples ranged from 0.384 to 0.539 fibers per cubic centimeter (f/cc). The area samples ranged from 0.02 to 0.086f/cc. Total particulate material concentrations of 2.673 to 21.55 milligrams per cubic meter (mg/m3) were found. Most trace metal concentrations were low or unmeasurable. Area samples for total particulate materials were 0.46 to 0.357mg/m3, and respirable particulate material samples ranged from 0.291 to 0.471mg/m3. The author concludes that the only exposures above OSHA standards were for total airborne particulate material for the plasterer, and recommends the development of a method for protecting the plasterer during application of the flame proofing material, and the use of respiratory protection whenever possible.
