Use caution to avoid creating, breathing or ingesting dust
when servicing brakes. Check for applicable laws, regulations
and insurance/enterprise policies prior to commencing work.
Recommended Work Practices
Separate Work Area
- Service brakes in an area where these
precautions are always taken for all work. Wear clothes used
only for brake work.
Respiratory Protection - Wear a respirator equipped with a
high-efficiency (HEPA) filter approved by NIOSH or MSHA
for brake work.
Wear respiratory protection at all times during brake servicing
(including grinding or machining brake drums), beginning
with the removal of the wheels, through shop cleanup after
completion of brake work (including emptying vacuums,
changing HEPA filters and rag disposal).
Procedures for Servicing Brakes
•
Service the removed brake assembly in a negative
pressure enclosure. The enclosure should be equipped
with a HEPA vacuum and worker arm sleeves. With the
enclosure in place, use the HEPA vacuum to loosen and
vacuum residue from brake parts.
•
Alternatively, use a catch basin with water and a
biodegradable, non-phosphate, water-based detergent to
wash the brake drum and other brake parts. Apply the
solution with low pressure to prevent dust from becoming
airborne. Allow the solution to flow between brake drum
and brake support. Thoroughly wet the wheel hub and
brake assembly components to control dust, prior to
removal of brake shoes. Wipe parts clean with a cloth.
•
If an enclosed vacuum system or brake washing
equipment is not available, carefully clean the brake parts
in open air. Use a fine mist from a pump spray bottle to
wet parts. Use a solution containing water, and, if
available, a biodegradable, non-phosphate, water-based
detergent. Thoroughly wet the wheel hub and brake
assembly components to control dust, prior to removal of
brake shoes. Wipe parts clean with a cloth.
Dust Control - Use only HEPA-equipped vacuum cleaners.
Never blow dust with an air gun. Do not dry brush parts.
Cleaning Fluids - NEVER use carcinogenic solvents,
flammable solvents, or solvents that can damage brake
components as wetting agents.
Work Area -. Clean work areas with a HEPA-equipped
vacuum cleaner or by damp wiping. NEVER use an ordinary
shop vac, compressed air or dry sweepers.
When replacing a HEPA filter, wet the used filter with a fine
water mist. Bag and carefully dispose of the used filter.
Hygiene - Wash hands immediately after brake work, and
before eating, drinking or smoking. Clean clothes with a
HEPA-equipped vacuum before removing them. Keep food
and drink out of the work area.
Shower after work. Do not wear work clothes home. Use a
vacuum equipped with a HEPA filter to vacuum work clothes
after they are worn. Launder them separately.
Waste Disposal - Dispose of discarded linings, used rags,
cloths and HEPA filters with care, such as in sealed and
labeled plastic bags. Consult applicable EPA, national,
regional and local regulations on waste disposal.
Regulatory Guidance - OSHA, NIOSH, MSHA, and EPA,
are regulatory agencies in the United States. These references
are to provide further guidance to employers and workers
employed within the United States. Employers and workers
employed outside of the United States should consult the
regulations that apply to them for further guidance.
