Asbestos dust and preliminary industrial hygiene survey Raybestos- Manhattan, Manheim, Pennsylvania.
NIOSH 1971 Nov; 1-:2
Worker exposures to asbestos (1332214) were surveyed at the Manheim Division of the Raybestos-Manhattan Company (SIC-3292) in Pennsylvania on November 15 and 16, 1971. Work processes, worker protection and medical monitoring programs, and workplace ventilation and housekeeping systems were evaluated. A total of 355 personal air samples were collected from the textile, friction and packing areas of the company. Exposures of the waste machine operator, fiber preparation stocker, carding stocker, ring spinner and machine brander exceeded the OSHA 8 hour time weighted average standard of 5 fibers per milliliter greater than 5 microns in length. The OSHA 15 minute peak standard of 10 fibers per milliliter was exceeded at the waste machine, fiber preparation and machine brander stations. Workplace ventilation was insufficient. The author recommends evaluation of the ventilation system in the fiber preparation and carding areas. Ventilation should be provided in the spinning operations area, and local exhaust ventilation should be installed at machine branding sites.
