Moreover, in contrast to wool orcotton garments, it was found that asbestos fibers will not readily adhere to Tyvek garments. One disposable overall has been tested and found suitable under appro priate temperature conditions. Others, perhaps equally suitable, may also exist. While not the perfect answer to the problem of bringing asbestos and other insulation dusts home on work clothes, disposable overalls are the most practical solution 8t this time. What now must be accomplished is to make their availability widespread. Jack StevenKm participating in the field trials of disposable overalls held in Wilmington, Delaware on June S. (Continuedfrom first page) tore easily, if they were inexpensive, or if durable, they were costly. This problem no longer exists. A variety of manufacturers make dispos able overalls of Tyvek and typical costs are about SI.50 per garment. Moreover, there was little problem with the material tearing in the gar ments tested. Thus durable, disposable overalls can be obtained at a cost of less than 2% of that of the employer's wage costs. If uniformly made available by contractors in an area, such costs can simply be included in any contract es timate. Laboratory tests also indicated the suitability of Tyvek overalls for insula tion work. Tests were conducted by IIHRP and Dupont personnel at Dupont's Haskell Laboratory for In dustrial Hygiene and Toxicology to measure the penetration of asbestos fibers through Tyvek and other materia) and to determine the adhesion of fibers to the material. The results of these laboratory tests showed the Tyvek material to be rela tively resistant to the penetration of as bestos fibers from insulation material. As the temperature mounted to 94* during the field trials of the disposable overalls some soon became indeed disposable. (Continued from third page) doesn't even reach the change area, it isn't going any farther. The best available way to accom plish this is for workmen to wear coveralls which can be removed on the job and disposed of with other construc tion waste. This practice, together with the availability of change rooms and strict attention to their clean up. will go far towards eliminating household con tamination. Glenn White and Constance Eddy of E. 1.
