Ret Exposure of Asarco Employees to Asbestos
The following is an estimate of the number of Asarco employees by plant potentially exposed to "measurable" concentrations of airborne asbestos fibers. This estimate was arrived at by consultation with the Field Services Staff and review of environmental survey reports.

This estimate does not include employees working in the same general area where asbestos is being handled, the use of asbes tos millboard as heat shields or asbestos cloth as welding curtains because it is not believed that "measurable" asbestos fiber concentrations would be found using the prescribed OSH& sampling and counting methods.
