21. Exposure to Asbestos and Exposure Limits: a. No more than . 2 fibers (longer than 5 microns) per cubic centimeter of air for an 8-hour time-weighted average; and for an excursion limit of thirty minutes, no more than an average of 1.0 fiber per cubic centimeter of air. b. The following engineering controls must be used to keep asbestos exposure below limits: Isolation, Enclosure, Exhaust Ventilation, Dust Collection. C. The following work practices must be followed: Asbestos waste and debris must be collected in sealed impermeable bags. d. Spills must be cleaned up promptly. e. Materials must be wetted before removal from containers unless exposure is controlled by ventilation. f. Asbestos waste and debris must be collected in sealed impermeable bags. g. When engineering controls are not feasible, respiratory protection for workers is required. h. If the exposure may exceed the limit, asbestos concentration must be determined (at employee ' s breathing zone) . i. Caution signs must be displayed at locations where w asbestos fiber concentration may exceed the exposure limit. j . All material or scrap containing asbestos must bear a label - CAUTION: CONTAINS ASBESTOS FIBERS. AVOID CREATING DUST. BREATHING ASBESTOS DUST MAY CAUSE SERIOUS BODILY HARM. 22 . Ventilation in enclosed places must be sufficient to prevent flammable vapor concentration from exceeding 25% of the L.E.L. 23 . All corrosive liquids containers must be plainly marked with a warning legend. Employees must use appropriate protective equipment when handling corrosives. When employees handle corrosives frequently, a deluge shower and bubble-fountain must be provided. 24 . All Flammable/Combustible containers must be plainly marked with a warning legend.
