Exposure to asbestos (1332214) while manufacturing an asphalt based roofing compound was investigated at Grundy Industries, Inc., (SIC- 2952) in Joliet, Illinois, in response to a request from the owner and manager. Bags containing asbestos were fed onto a conveyor system and subjected to a fluffing operation to agitate the fibers. After mixing, the fiber was encapsulated and little asbestos dust was generated. Personal breathing samples were collected near the breathing zone of employees likely exposed to airborne asbestos fibers. The asbestos bag opener, the control panel operator, the forklift driver, and a dispensing line worker were monitored. Total fiber counts on the five analyzable samples ranged from 0.08 to 0.37 fibers per cubic centimeter of air. The asbestos bag opener and the forklift operator were exposed to concentrations above the OSHA limit of 0.2 fibers per cubic centimeter. The author recommends that asbestos be replaced by a less toxic substance. Engineering controls such as isolation, enclosure, and ventilation should be used to control exposure to asbestos if a suitable substitute cannot be found. Industrial type vacuum equipment should be installed for cleaning purposes. Respirators should be used during non routine operations.
