Recent industrial hygiene studies have demonstrated overexposure to asbestos, fiber in air during certain vehicle brake rebuilding and inspection operations. Overexposure occurred when brakes and brake drum were cleaned using compressed air blcwoff. In order to preclude overexposure to asbestos fiber in air, the. following procedure is recommended: . . Vehicle brakes and brake drums shall be cleaned using an industrial type vacuum cleaner with a filtering system efficient to a three micron particle size. Under no circumstances shall, cppipressed air blowoff be used to clean brakes and brake drums. '' . Disposal of asbestos laden dust from the vacuum shall be done by wet methods of dust suppression or the employe performing the operation shall use a respirator specified by the U.S. Bureau of Mines for pneumoconiosis producing dust under approvals 21C and Schedule 21. Approval 21C specifies single use respirators approved for pneumo coniosis producing dusts. . Disposal of asbestos laden waste from the vacuum cleaner shall be in sealed containers labeled per subparagraph g and h.
