The mineral wool which reportedly constitutes 70% of the insulating*' material is a fibrous material made from melted slag. Based on information obtained from the limited number of environmental air samples collected it would appear that the exposure of workers, employed in nearby work areas* to asbestos dust and fibers generated by.the asbestos spraying operation would constitute more of a nuisance than a potential health hazard. Your earlier recommendation that dust respirators and goggies be made available for employees working in the vicinity of the asbestos spraying operation would seem the most practical approach to the problem under present conditions* If we can be of further assistance* please let us' koow*' ' ,.* v Sincerely, ft.
