| Abstract | Environmental and breathing zone samples were analyzed for asbestos (1332214) at Easton Elementary School (SIC-2869), Morgantown, West Virginia in February 1983. The evaluation was requested by the superintendant of schools of the county on behalf of the pupils and staff of the school on suspicion of an asbestos hazard in an area where damaged pipe insulation was being replaced. Fibers with an aspect ratio of 3:1 or larger and a minimum length of 5 microns were counted using phase contrast microscopy. Analysis of bulk and settled dust samples confirmed the presence of chrysotile (12001295) asbestos. The majority of the fibers counted, however, were found to be fiberglass (not asbestos) and had a concentration of less than 0.1 fibers per cubic centimeter (cm3). Samples from filters on masks used by two maintenance workers had concentrations of 0.18 and 0.50 fibers/cm3, but again, most of the fibers were fiberglass. The current NIOSH standard for asbestos fibers, 5 microns or longer, is 0.1 fibers/cm3 time weighted average or 0.5 fibers/cm3 for any 15 minute period. The author concludes that there was no asbestos health hazard present at the school. |
