Current through Register 2024 Notice Reg. No. 28, July 12, 2024
This mandatory appendix specifies engineering controls
						and work practices that must be implemented by the employer during automotive
						brake and clutch inspection, disassembly, repair, and assembly operations.
						Proper use of these engineering controls and work practices by trained
						employees will reduce employees' asbestos exposure below the permissible
						exposure level during clutch and brake inspection, disassembly, repair, and
						assembly operations. The employer shall institute engineering controls and work
						practices using either the method set forth in subsection [A] or subsection [B]
						of this appendix, or any other method which the employer can demonstrate to be
						equivalent in terms of reducing employee exposure to asbestos, as defined, and
						which meets the requirements described in subsection [C] of this appendix. For
						those facilities in which no more than 5 pairs of brakes or 5 clutches are
						inspected, disassembled, reassembled, and/or repaired per week, the method set
						forth in subsection [D] of this appendix may be used. [A] Negative Pressure
						Enclosure/HEPA Vacuum System Method:
(1) The brake and clutch inspection, disassembly, repair,
						and assembly operations shall be enclosed to cover and contain the clutch or
						brake assembly and to prevent the release of asbestos fibers into the worker's
						breathing zone.
(2) the enclosure shall be sealed tightly and thoroughly
						inspected for leaks before work begins on brake and clutch inspection,
						disassembly, repair, and assembly.
(3) The enclosure shall be such that the worker can
						clearly see the operation and shall provide impermeable sleeves through which
						the worker can handle the brake and clutch inspection, disassembly, repair and
						assembly. The integrity of the sleeves and ports shall be examined before work
						begins.
(4) A HEPA-filtered vacuum shall be employed to maintain
						the enclosure under negative pressure throughout the operation. Compressed-air
						may be used to remove asbestos fibers or particles from the enclosure.
(5) The HEPA vacuum shall be used first to loosen the
						asbestos-containing residue from the brake and clutch parts, and then to
						evacuate the loosened asbestos-containing material from the enclosure and
						capture the material in the vacuum filter.
(6) The vacuum's filter, when full, shall be first wetted
						with a fine mist of water, then removed and placed immediately in an
						impermeable container, labeled according to subsection (k)(8) of this section,
						and disposed of according to subsection (
l
) of this
						section.
(7) Any spills or releases of asbestos-containing waste
						material from inside of the enclosure or vacuum hose or vacuum filter shall be
						immediately cleaned up and disposed of according to subsection
						(
l
) of this section.
[B] Low Pressure/Wet Cleaning Method:
(1) A catch basin shall be placed under the brake
						assembly, positioned to avoid splashes and spills.
(2) The reservoir shall contain water containing an
						organic solvent or wetting agent. The flow of liquid shall be controlled such
						that the brake assembly is gently flooded to prevent the asbestos-containing
						brake dust from becoming airborne.
(3) The aqueous solution shall be allowed to flow between
						the brake drum and brake support before the drum is removed.
(4) After removing the brake drum, the wheel hub and back
						of the brake assembly shall be thoroughly wetted to suppress dust.
(5) The brake support plate, brake shoes and brake
						components used to attach the brake shoes shall be thoroughly washed before
						removing the old shoes.
(6) In systems using filters, the filters when full shall
						be first wetted with a fine mist of water, then removed and placed immediately
						in an impermeable container labeled according to subsection (k)(8) of this
						section, and disposed of according to subsection (
l
) of this
						section.
(7) Any spills of asbsetos-containing aqueous solution or
						any asbsetos-containing waste material shall be cleamed up immediately and
						disposed of according to subsection (
l
) of this
						section.
(8) The use of dry brushing during low pressure/wet
						cleaning operations is prohibited.
[C] Equivalent Methods:
An equivalent method is one which has sufficient written
						detail so that it can be reproduced, and for which it has been demonstrated
						that the exposures resulting from the equivalent method are equal to or less
						than the exposures which would result form the use of the method described in
						subsection [A] of this appendix. For purposes of making this comparison, the
						employer shall assume that exposures resulting from the use of the method
						described in subsection [A] of this appendix shall not exceed 0.016 f/cc, as
						measured by the OSHA reference method and as averaged over at least 18 personal
						samples.
[D] Wet Method:
(1) A spray bottle, hose nozzle, or other implement
						capable of delivering a fine mist of water or amended water, or other delivery
						system capable of delivering water at low pressure, shall be used to first
						thoroughly wet the brake and clutch parts. Brake and clutch components shall
						then be wiped clean with a cloth.
(2) The cloth shall be placed in an impermeable
						container, labeled according to subsection (k)(8) of this section, and then
						disposed of according to subsection (
l
) of this section; or
						the cloth shall be laundered in a way to prevent the release of asbestos fibers
						in excess of 0.1 fiber per cubic centimeter of air.
(3) Any spills of solvent or any asbstos-containing waste
						material shall be cleaned up immediately according to subsection
						(
l
) of this section.
(4) The use of dry brushing during the wet method
						operations is prohibited.
