Page 4 of 8 check that the vacuum container seals and clips are in proper functioning order according to the manufacturer's instructions. 2. Remove the wheel. 3. Turn on the asbestos vacuum cleaner. 4. Place the enclosure over the drum, making sure it forms a tight seal behind the backing plate. 5. Place hands into the attached rubber gloves. 6. Remove the brake drum. Some equipment allows use of a hammer or other tools inside the enclosure for drums that are hard to remove. 7. Blow dust off the drum and brake assembly using the air gun attachment inside the enclosure. 8. Blow dust off all inside surfaces of the enclosure towards the vacuum exit using the air gun attachment inside the enclosure. 9. Remove the enclosure and turn off the vacuum cleaner. If grease accumulates on the inside surfaces of the enclosure, clean according to the manufacturer's instructions with a soft cloth and with the vacuum running. Dispose of the cloth according to OSHA regulations. This cloth should not be handled with bare hands. Disc Brakes For disc brakes, vacuum the pads, rotor, and caliper directly with a crevice attachment and avoid handling them before vacuuming. Filter Change and Waste Disposal Asbestos vacuum cleaners have several filters. Changing filters and disposing of asbestos waste can release dangerous concentrations of asbestos unless done properly. Some equipment allows for filter or collection hag change while the vacuum motor is running. This draws loose brake dust into the vacuum collector and away from the mechanic, reducing the risk of exposure. Some equipment has a renewable main filter that can be cleaned repeatedly without opening the vacuum cleaner. Ideally, all vacuum equipment should be designed to prevent opening the vacuum chamber when the vacuum motor is turned off, since opening the chamber can cause release of collected asbestos into the air. Always follow the manufacturer's instructions for filter or collection bag change. Request a demonstration and practice session from the manufacturer to go through all steps for equipment use and filter or collection bag change, until each person who is to use this equipment is completely familiar with these procedures. Place the filter or collection bag directly into a 6 mil (heavy) plastic bag and double tie. Place the bag directly into a 55-gallon drum or similar leak proof, air-tight container designated for asbestos waste according to OSHA regulations and mark it as follows: CAUTION Contains Asbestos Fibers Avoid Breathing Dust Breathing Asbestos Dust Can Cause Lung Disease and Cancer Keep this drum for asbestos waste locked between filter or collection bag changes. Transport and disposal of asbestos waste should be done only by individuals familiar with procedures for handling asbestos waste in accordance with EPA's asbestos disposal guidance. Clutch Repair Significant exposure can also occur during clutch repair. Since a mechanic's head is typically under the clutch assembly during clutch repair, asbestos often falls on a mechanic's face and clothing.
