For the purpose of this section. (tj ''Asbestos*' includes chrysotile, amosite, crocidolite, tremolite, anthophyliilc, and actinolite. (2) "Asbestos fibers*' means asbestos fibers . longer than 5 micrometers. (b) Permissible exposure to airborne concen trations of asbestos fibers. (!) Standard effective July 7, 1972. The 8-hour time-weighted average airborne concentra tions of asbestos fibers to which any employee may be exposed shall not exceed five fibers, longer than 5 micrometers, per cubic centimeter of air, as determined by the method prescribed in paragraph (e) of. this section. (2) Stondord effective July 1, 1976. The 8-hour time-weighted average airborne concentre* tions of asbestos fibers to which any employee may be exposed shall not exceed two fibers, longer than 5 micrometers, per cubic centimeter of air, as determined by the method prescribed in paragraph (e) of this section. (3) Ceiling conccntrotion. No employee shall be exposed at any time to airborne concentra tions of asbestos fibers in excess of 10 fibers, longer than 5 micrometers, per cubic cen timeter of air, as determined by the method prescribed in paragraph (e) of this section. (t) Methods of complionce. (1) Engineering methods. (i) Engineering controls. Engineering Con trols, such as, but not limited to, isolation, enclosure, exhaust ventilation, and dust collection, shall be used to meet the exposure limits prescribed in paragraph (b) of this section. (i!) loco) exhovst venlilolion. (a) Local exhaust ventilation and dust collection systems shall be designed, constructed, installed, and maintained in accordance with the American National Standard Fundamentals Governing the Design and Operation of Local Exhaust Systems, ANSI Z9.2-1971, which is incorporated by reference herein. (b) See $ 1910.6 concerning the availabil ity of ANSI Z9.2-1971, and the mainte nance of a historic file in connection therewith.

All hand-operated and power-operated tools which may produce or release asbestos fibers in excess of the exposure limits prescribed in paragraph (b) of this section, such as, but not limited to, saws, scorers, abrasive wheels, and drills, shall be provided with local exhaust . ventilation systems in accordance with subdivision (ii) of this subparagraph- (2) Work prodicel. (i) Wet method*. Insofar as practicable, asbestos shall be handled, mixed, applied, removed, cut, scored, or otherwise worked in a wet st8te sufficient to prevent the emission of airborne fibers in excess of the exposure limits prescribed in para graph (b) of this section, unless the use fulness of the product would be dimin ished there! (ii) Porticulor product* ond operotion*. No asbestos cement, mortar, coating, grout, plaster, or similar material containing asbestos shall be removed from bags, car tons, or other containers in which they are shipped, without being either wetted, or enclosed, or ventilated so as to prevent effectively the release of airborne asbes tos fibers in excess of the limits prescribed in paragraph (b) of this section. 8005 0830 PRODUCED BY FORD
