Worker exposures to asbestos (1332214) were determined at the Pittsburgh-Corning Corporation facility (SIC-1799) in Tyler, Texas, from October 26 to 29, 1971. Medical questionnaires and examinations were given. The company had no medical facilities or first aid room. Medical services were furnished by local clinics and occupational health consultation was available from corporate headquarters in Pennsylvania. Atmospheric samples for fiber counts were collected on millipore filters. Of the 138 samples taken, 117 exceeded the current hygienic standards of 5 fibers per milliliter of air and were greater than 5 microns in length. In all areas and operations, except the office area, average and maximum concentrations of dust significantly exceeded the current threshold limit value of the American Conference of Governmental Industrial Hygienists, and the Emergency Standard of the U.S. Department of Labor of 12 fibers per milliliter of asbestos, for fibers greater than 5 microns in length. Large quantities of dust were observed throughout the facility, including the restroom and drinking fountains. The ventilation system was inadequate, with numerous functional deficiencies. Of the 63 male employees medically examined, several had possible pulmonary fibrosis, and 7 of 18 workers with more than 10 years employment had symptoms of asbestosis. The authors recommend that immediate measures be taken to reduce employee hazards, including a complete redesign of the ventilation system, relocation of all dust collectors, appointment of a safety committee, removal of gas heaters, creation of a respirator program, relocation of the lunch room, use of protective clothing, and disposal of all scrap materials.
