Be careful about public spaces, if people are walking around, plastic on the floor isn’t best advised. Use cardboard on a roll or sheets, or the Trimaco One Tuff sheeting is safe too, right way down it grips, and take it up when you leave each day.

If you suspect it is asbestos, you aren’t qualified to deal with any remedial work. If it is already painted and in good condition, at the most wash it down and repaint it.

I am not a qualified lead dust disposal expert, so check all this out, but my understanding, and from reading through the literature, lead paint buried under layers of non lead paint is not a danger - lead laden dust is the problem, so if you suspect lead paint, you can get LeadCheck swabs which you wipe over the surface, or get a company in to do site wide analysis (see below).

Only abrade wet and clean as you go before the dust is formed. You need to extract any dust with a Haz H rated vacuum. (Festools are rated now) and dispose of all contaminated dust, abrasives or clothing safely.

Don’t let any non-workers walk around unprotected while lead paint is being worked on.

Don’t go burning off suspected lead paint (the official advice seems a bit cavalier to me, don’t use naked flames makes sense, but you can use hot air guns or infra red strippers as long as you don’t over heat suspected lead paint and create fumes! Not very scientific, so just leave well alone.

In general terms: LIPSA site (LiPSA is listed by BCF as a qualified resource and I believe the guy is a forum member here?.)

[quote]Low-cost lead exposure monitoring can be carried out on-site by operatives and DIYers themselves. From reasonably accurate chemical-based indicators to laboratory accurate screening and analysis, a full range of lead testing options is now available to suit all budgets and compliance requirements.

For those requiring ‘professional’ sampling and full quantitative analysis by a formally trained and accredited specialist, LiPSA can advise on the most cost-effective sampling strategies.[/quote]

The basic summary of what to do / not do from BCF:

KEY DO’S AND DON’TS
If paint is in sound condition do NOT remove it, especially if the lead paint is not the top layer – just overcoat
If in doubt check whether old lead paint is present (see 3 above) Keep anyone not carrying out the work out of the area
Keep dusts to a minimum – only use wet abrasive paper
Do NOT use blow lamps or gas torches to strip paint
Do NOT create lead fumes by over-heating lead containing paints
Wear protective clothing and masks (if required)
Clean up thoroughly after the removal of old lead paint
Do NOT burn or incinerate lead-containing wastes.
