It can be a DIY job, though you need to be extremely careful to make sure that you do the job safely and completely.
Generally, if you are not cutting, sanding, drilling, or otherwise creating dust from the siding, you have nothing to worry about. Merely removing a nail and taking down a siding shingle will not place you in grave danger, or any kind of danger. But because one thing often leads to another (i.e., merely removing a nail leads to the temptation to smash a shingle to remove it, all because the nail won't come out), I am issuing the full set of safety warnings.
My following steps come from personal experience and from the public domain source, Asbestos Removal Procedures for Homeowners, by the Olympic Region Clean Air Agency.
- Post signs warning any “drop-in” friends, family, and other visitors of the work taking place. Lay a six-foot wide strip of 6-mil sheet plastic along the side of the house where removal is to occur. Try to work in the shade so the wetted siding will remain wet. Create an entrance/exit “transition” zone to the work area by laying down an additional six-foot by six-foot foot piece of sheet plastic in a convenient location next to the plastic strip along the wall. Keep a plastic disposal bag at this location.
- Hose down about 50 square feet of siding. Mix approximately 1 teaspoon of liquid dish-washing detergent with water in the pint size spray bottle or about one half cup of detergent in a garden pump sprayer.
- Suit up with your disposable coveralls. Also put on gloves, goggles, boots, and respirators equipped with HEPA filers.
Don't want to buy your abatement materials piecemeal? One company sells entire sets of asbestos removal supplies.
- Remove pieces of siding by pulling nails or cutting nail heads so as to minimize breakage. If necessary, carefully lift siding pieces with pry tool to expose nail heads. If siding should begin to crack or crumble, immediately wet the cracked or broken areas with the pint size spray bottle or garden pump sprayer. Breakage releases asbestos fibers. Wet the back of each piece of siding as it is removed. Lower removed siding to the ground. Do not throw or drop it. Keep all debris on the plastic strip and keep on wetting it.
- Load wetted debris and other contaminated materials into sturdy containers like cardboard boxes or burlap sacks. If cardboard boxes are used, line each box with 6 mil polyethylene and leave enough excess plastic to cover the debris and seal the plastic-covered debris with duct tape. Boxes should then be wrapped in one or more layers of 6- mil plastic or inserted into a single pre-marked asbestos waste disposal bag.
- Double bag or wrap other filled containers in pre-marked 6- mil asbestos waste disposal bags. Twist top of each filled bag, bend twisted part in half and seal it with duct tape. If containers are to be wrapped rather than bagged, use 6-mil polyethylene plastic and ensure all seams are sealed with duct tape. Affix an asbestos warning label to each sealed package.
- At the end of each work shift, re-wet any debris on the strip of plastic next to the wall. While continuing to stand on the plastic strip next to the wall where the removal is being done, double bag or wrap all debris as described above. Then wrap or roll up the strip of plastic along the wall, working your way back to the entrance/exit “transition zone” strip of plastic. Step onto the transition zone plastic and double bag or wrap the last of the strip plastic.
- While standing on this last piece of plastic sheeting, spray yourself (or each other) with water to wet down any asbestos debris/fibers on the outside of your respirator and disposable coveralls.
- Remove boots. Then remove your disposable gloves and coveralls by peeling them off and turning them inside out as you remove them. Leave these contaminated items on the transition zone plastic for disposal. Step off the last plastic sheet.
- Take off respirators and remove their filters for disposal. Then wash off and wipe down the tools used in removal, along with your respirators, goggles and boots. Move each item off the plastic as it is cleaned.
- Double bag remaining debris, transition zone plastic, and disposable items in properly labeled asbestos disposal bags or double wrap them in 6-mil plastic sheets. Tightly seal each bag or package tightly with duct tape. Use wet rags for any further clean-up. Never attempt to vacuum or sweep up asbestos debris. This will cause any fibers present to become airborne. Take a shower.
- Asbestos debris from an asbestos project must be disposed of at disposal sites or transfer stations licensed to receive such waste.
- All debris must be sealed in two layers of 6-mil polyethylene plastic. Remember, siding pieces have sharp edges that can perforate this plastic material unless the siding is first loaded into sturdy containers. Packaged debris in punctured plastic will not be accepted by waste disposal sites. You must write your last name, address, and date of removal on each container. Check with the disposal site for any additional requirements.
