Environmental and breathing zone samples were analyzed for asbestos (1332214) at Easton Elementary School (SIC-8211), 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 masks used by two maintenance workers had concentrations of 0.18 and current NIOSH standard for asbestos fibers, 5 microns or longer, is minute period. The author concludes that there was no asbestos health hazard present at the school.
