Abstract
Apparatus and method for determining the asbestos fiber release potential of asbestos-containing compositions comprises an impact member which is repeatedly impacted with a selected area of the asbestos-containing composition and in which asbestos fibers which become airborne as a result of the impacts are collected by means of a collector system disposed around the area of impact. The invention has particular utility for the in situ testing of asbestos-containing fire-retardant compositions which have been previously applied to structural elements of buildings.
