(2> "Asbestos fibers" means asbestos fibers longer than 5 micrometers. (b) Permissible exposure to airborne concentrations of asbestos fibers--(1) Standard effective July 7, 1972. The 8-hour time-weighted average airborne concentrations 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 pre scribed in paragraph (e) of this section. (2) Standard effective July 1, 1976. The 8-hour time-weighted average air borne concentrations 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 pre scribed in paragraph (e) of this section. (3) Ceiling concentration. No em ployee shall be exposed at any time to airborne eencentrations of asbestos fibers in excess of 10 fibers, longer than 5 micrometers, per cubic centimeter of air, as determined by the method pre scribed iivparagraph (e) of this section.

Such employee shall be rotated to another job or given the opportunity to transfer to a different po sition whose duties he is able to perform with the same employer, in the same geo graphical area and with the same senior ity, status, and rate of pay he had just prior to such transfer, if such a different position is available. (3) Special clothing: The employer shall provide, and require the use of, spe cial clothing, such as coveralls or similar whole body clothing, head coverings, gloves, *and foot coverings for any em ployee exposed to airborne concentra tions of asbestos fibers, which exceed the ceiling level prescribed in paragraph (b) of this section. (4) Change rooms: (i) At any fixed place of employment exposed to airborne concentrations of asbestos fibers in ex cess of the exposure limits prescribed in paragraph (b) of this section, the em ployer shall provide change rooms for employees working regularly at the place.

(c) Contaminated clothing shall be transported in sealed impermeable bags, or other closed, impermeable containers, and labeled in accordance with para graph (g) of this section. (e) Method of measurement. All de terminations of airborne concentrations of asbestos fibers shall be made by the membrane filter method at 400-450 X (magnification) (4 millimeter objective) with phase contrast illumination. (f) Monitoring--(1) Initial determi nations. Within 6 months of the publi cation of this section, every employer shall cause every place of employment where asbestos fibers are released to be monitored in such a way as to determine whether every employee's exposure to asbestos fibers is below the limits pre scribed in paragraph (b) of this sec tion. If the limits are exceeded, the em ployer shall immediately undertake a compliance program in accordance with paragraph (c) of this section. (2) Personal monitoring--<i> Sam ples shall be collected from within the breathing zone of the employees, on membrane filters of 0.8 micrometer po rosity mounted in an open-face filter holder. Samples shall be taken for the determination of the 8-hour timeweighted average airborne concentra tions and of the ceiling concentrations of asbestos fibers. (ii) Sampling frequency and patterns. After the initial determinations required by subparagraph (1) of this paragraph, samples shall be of such frequency and pattern as to represent with reasonable accuracy the levels of exposure of em ployees. In no case shall the sampling be done at intervals greater than 6 months for employees whose exposure to asbestos may reasonably be foreseen to exceed the limits prescribed by paragraph (b) of this section. (3) Environmental monitoring--(i) samples shall be collected from areas of a work environment which are represent ative of the airborne concentrations of asbestos fibers which may reach the breathing zone of employees. Samples shall be collected on a membrane filter of 0.8 micrometer porosity mounted in an open-face filter holder. Samples shall be taken for the determination of the 8hour time-weighted average airborne concentrations and of the ceiling con centrations of asbestos fibers. (ii) Sampling frequency and patterns. After the initial determinations required by subparagraph (1) of this paragraph, samples shall be of such frequency and pattern as to represent with reasonable accuracy the levels of exposure of the employees. In no case shall sampling be at intervals greater than 6 months for employees whose exposures to asbestos may reasonably be foreseen to exceed the exposure limits prescribed in para graph (b) of this section. (4) Employee observation of monitor ing. Affected employees, or their rep resentatives, shall be given a reasonable opportunity to observe any monitoring ' required by this paragraph and shall have access to the records thereof. (g)Caution signs and labels. (1) Cau tion signs, (i) Posting. Caution signs shall be provided and displayed at each location where airborne concentrations of asbestos fibers may be in excess of the exposure limits prescribed in paragraph (b) of this section. Signs shall be posted at such a distance from such a location so that an employee may read the signs and take necessary protective steps be fore entering the area marked by the signs. Signs shall be posted at all ap proaches to areas containing excessive concentrations of airborne asbestos fibers. (ii) Sign specifications. The warning signs required by .subdivision (i) of this subparagraph shall conform to the re quirements of 20" x 14" vertical format signs specified in 11910.145(d)(4), and to this subdivision.
