§5208.1. Non Asbestiform Tremolite, Anthophyllite, and Actinolite.

This section applies to occupational exposures to non-asbestiform tremolite, anthophyllite, and actinolite.

(a) The 8-hour time weighted average concentration of airborne non-asbestiform tremolite, anthophyllite, and actinolite fibers to which any employee may be exposed shall not exceed 2 fibers, longer than 5 micrometers, per cubic centimeter of air as determined by the membrane filter method using phase contrast illumination and 400 to 450X magnification. The ceiling or short time concentration to which employees are exposed shall not exceed 10 fibers, longer than 5 micrometers, per cubic centimeter of air.

(b) Engineering Controls. Controls such as, but not limited to, isolation, enclosure, exhaust ventilation, and dust collection shall be used to meet the exposure limits in 5208.1(a). All hand-operated and power-operated tools which may produce or release non-asbestiform tremolite, anthophyllite, and actinolite fibers in excess of such limit shall be provided with local exhaust ventilation systems. The American National Standards Institute Z9.2-1971 Standard Governing the Design and Operations of Local Exhaust Systems shall be used to design, construct, install, and maintain exhaust ventilation and dust collection systems in accordance with section 5143.

(c) Work Practices.

(1) Non-asbestiform tremolite, anthophyllite, and actinolite shall be mixed, handled, applied, removed, cut, or otherwise worked wet insofar as practicable.

(2) Non-asbestiform tremolite, anthophyllite, and actinolite spills shall be cleaned up promptly.

(3) Non-asbestiform tremolite, anthophyllite, and actinolite-containing cement, mortar, coating, grout, plastic, or similar material shall not be removed from bags, cartons, or other containers without being wetted, unless it is enclosed and/or ventilated to effectively control airborne fibers as specified in section 5208.1(a).

(4) The spraying of any substance containing any amount of non-asbestiform tremolite, anthophyllite, and actinolite in or upon a building or other structure during its construction, alteration, or repair is prohibited.

EXCEPTIONS: (A) Exterior and interior coatings and laminating resins containing encapsulated non-asbestiform tremolite, anthophyllite, and actinolite fibers bound within finished product from manufacture through application.(B) Cold process asphalt roof coatings. (C) Substances containing less than one-quarter of 1 percent non-asbestiform tremolite, anthophyllite, and actinolite solely as a result of naturally occurring impurities in the substance or its components.

(5) Non-asbestiform tremolite, anthophyllite, and actinolite waste, scrap, debris, bags, containers, equipment or other non-asbestiform tremolite, anthophyllite, and actinolite-contaminated material consigned for disposal which may produce in any reasonably foreseeable use, handling, storage, processing, disposal, or transportation employee exposure to airborne non-asbestiform tremolite, anthophyllite, and actinolite fibers in excess of the limits prescribed by section 5208.1(a) shall be collected and disposed of in sealed impermeable bags or other closed im--permeable containers which shall be labeled in accordance with section 5208.1(i).

(d) Respiratory Protective Equipment. When engineering controls and wet handling methods are not feasible or are incapable of controlling the concentration or in an emergency, respiratory protection and shall be provided and worn in accordance with provisions of section 5144 and the following requirements:

(1) Reusable or single-use air filtering respirators shall be used when the concentration exceeds the levels specified in section 5208.1(a), but may not be used when the concentration may reasonable be expected to exceed 10 times the limit.

(2) Powered air filtering respirators may be worn for lower concentrations, but shall be worn when the non-asbestiform tremolite, anthophyllite, and actinolite fiber concentration is reasonable expected to exceed 10 times, but not 100 times the limit in section 5208.1(a).

(3) Continuous flow or pressure demand air-line respirators or self-contained breathing apparatus may be worn for lower concentrations, but shall be worn when the non-asbestiform tremolite, anthophyllite, and actinolite fiber concentration is reasonably expected to exceed 100 times the limit in section 5208.1(a).

(4) No employee shall be assigned to tasks requiring the use of respirators if based on his most recent examination an examining physician determines that the employee will be unable to function normally wearing a respirator or that the safety or health of the employee or other employees will be impaired by his use of the respirator. Such employee shall be rotated to an equivalent job whose duties he is able to perform, with the same employer, in the same geographical area and with the same seniority, status, and rate of pay, if such a position is available.

(e) Change Rooms and Special Clothing.

(1) The employer shall provide and require the use of special clothing such as coveralls or similar whole body clothing, head coverings, gloves, and foot coverings for any employee exposed to airborne concentrations of non-asbestiform tremolite, anthophyllite, and actinolite fibers which exceed the ceiling anthophyllite, and actinolite fibers in excess of the exposure limits prescribed in section 5208.1(a).
