Exposure to mineral wool fibers, respirable airborne particulate matter total airborne particulate matter, trace metals and carbon- monoxide (630080) were determined, and limited heat stress measurements were taken for employees of Shepherd's Insulation, Incorporated (SIC-3296), in Pueblo, Colorado, on September 24, 1976. The company had no formal safety and industrial hygiene program. Airborne fiber concentrations ranged from 0.087 to 1.359 fibers per cubic centimeter and were below NIOSH standards. Total airborne particulate material concentrations ranged from 0.910 to 9.852 milligrams per cubic meter (mg/m3). Trace metal concentrations in the total particulate material ranged from 0.5 to about 120.0 micrograms per cubic meter (micrograms/m3) for zinc, 1.1 to 12.0 micrograms/m3, for lead, and less than 1.0 to about 124.0 micrograms/m3 for manganese. Respirable particulate material was measured at 2.565mg/m3. Carbon-monoxide measurements inside the insulation truck did not exceed the OSHA standard of 50 parts per million over an 8 hour day. Botsball heat measurements ranged from 72 degrees F inside the attic to 78 degrees F inside the truck. The author recommends continued use of dust masks, ventilation of the attic when possible, redirection of truck exhausts, and truck ventilation.
