Cleanup and disposal
Asbestos waste and debris must be disposed of quickly and correctly to minimise any asbestos fibre exposure to the homeowners or workers.
Procedure for cleaning the work area
Carefully clean dust and debris form all horizontal surfaces (e.g. floor, window sills, and architraves) near the work area using either of the following two methods:
Method one: (wet wipe method)
Wet wipe method to clean dust and debris from the work area and horizontal surfaces using damp rags or disposable wipes. Then using a atomizer bottle mixed with a solution of PVA glue with a consistency of five parts water and one part glue (five to one). Spray the drop sheet to capture any missed residue and then fold the drop sheet on itself and dispose of as asbestos waste.
Follow the steps depicted below.

Step 1 Wet wipe the surface below the work area
1. Wet wipe the surface below the work area.
Step 2 Commence the removal of the protective floor covering
2. Once the area is cleaned and wipes are disposed of correctly into an approved asbestos waste bag or container, commence the removal of the protective floor covering.
Step 3 Disposing of the duct tape and wipes.
3. Disposing of the duct tape and wipes.
Step 4 Carefully fold the plastic sheeting
4. Carefully fold the plastic sheeting on it self, covering all previously exposed areas, and use as the last area of floor covering during the personal decontamination procedure.
Method two: (using a HEPA vacuum and wet wipe method)
Use an H rated industrial HEPA filter vacuum (that complies with AS/NZ 60335.2.69:2003 and AS4260-1997 for HEPA filtration) to control airborne fibres and dust to a HEPA filtered vacuum cleaner. When the vacuuming is completed then wet wipe the surfaces as mentioned in ‘Method one’. Please note that a household vacuum cleaner must not be used because it is not designed for this type of work and will cause an uncontrolled release of asbestos fibres.

Personal decontamination
Follow the steps depicted below and view the example video.
Step 1 Use a spray bottle to wet down coveralls
1. Use a spray bottle and water to wet down coveralls to capture any dust on the garment.
Step 2 Wet wipe boots, including the bottom of the boots
2. Wet wipe boots, including the bottom of the boots.
Step 3 Place the coveralls in the approved waste bag
3. Place the coveralls in the approved waste bag. Place any equipment to be used again like gumboots, respirators and tools in a separate approved asbestos waste bag which is correctly labelled and seal inside another bag. This is for safe transport to any other asbestos work area. Then, fold up the plastic drop sheet and place it in the approved asbestos waste bag.
Step 4 Wet down the disposable mask
4. Wet down the disposable mask and remove only once all the other items are safely in the approved asbestos bag. Reusable respirators should be wet wiped and placed inside an approved asbestos waste bag or container for reuse at another asbestos work site.
Step 5 Expel some of the air in the disposal bags
5. Expel some of the air in the disposal bag and then twist the neck of the bag whilst sealing the bag with duct tape.
Step 6 Tape the neck of the bag
6. Once the neck of the bag is fully taped bend it over on itself.
Step 7 Tape the end again
6. Once the neck of the bag is fully taped bend it over on itself.
Disposal of waste and clearance inspection of the work area
Visually inspect the work area including all horizontal surfaces to ensure they are clear of all visible dust and debris. Air monitoring is not normally required for this task.
Ensure that the work area is clean and tidy and all waste has been removed from site. No rubbish should remain on site after the work has been complete.
Dispose of the waste in accordance with the local council requirements.
Sign off any access permits and authority with the relevant person.
Accompany the PCBU or site owner to inspect the site to confirm that the area is clean and tidy and that the work is completed.
