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 paragraph [A] or paragraph [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 paragraph [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 paragraph [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 (j)
(4)
of this section, and disposed of according to subsection (k) 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 (k) 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 (j)
(4)
of this section, and disposed of according to subsection
						  (k) of this section.
(7) Any spills of asbsetos-containing aqueous solution
						  or any asbsetos-containing waste material shall be cleaned up immediately and
						  disposed of according to subsection (k) 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 from the use of the method
						  described in paragraph [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 paragraph [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 (j)
(4)
of this
						  section, and then disposed of according to subsection (k) 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 (k) of
						  this section.
(4) The use of dry brushing during the wet method
						  operations is prohibited.
