Old floor removal and asbestos

What the test measures

There is no reading here to hold against a limit. The question is whether the old floor, its backing or its adhesive contains asbestos, and EPA’s guidance for homeowners says how that is known:

The only way to be sure whether a material contains asbestos is to have it tested by a qualified laboratory.

What a valid report looks like

A complete record names, at minimum:

• each material sampled: the floor, its backing, and the adhesive under it;
• who took the samples, and their training and accreditation;
• the laboratory that tested them, and the date;
• the result for each sample.

On when to test, EPA says:

EPA only recommends testing suspect materials if they are damaged (fraying, crumbling) or if you are planning a renovation that would disturb the suspect material.

and on who takes the samples:

Samples should be taken by a properly trained and accredited asbestos professional (inspector).

Red flags

1. An old resilient floor or its adhesive is coming up with no test result. OSHA’s standard treats it as asbestos-containing until shown otherwise:

   Resilient flooring material including associated mastic and backing shall be assumed to be asbestos-containing unless an industrial hygienist determines that it is asbestos-free using recognized analytical techniques.

   OSHA 29 CFR 1926.1101, web page²

   and for older vinyl and asphalt flooring:

   Asphalt and vinyl flooring material installed no later than 1980 must also be considered as asbestos containing unless the employer, pursuant to paragraph (g)(8)(i)(I) of this section determines that it is not asbestos-containing.

   OSHA 29 CFR 1926.1101, web page²

2. The plan is to sand the old floor or its backing. OSHA’s standard, at 1926.1101(l)(3)(ii):

   Sanding of flooring material is prohibited.

   OSHA 29 CFR 1926.1101, web page²

   and, for removal, at 1926.1101(g)(8)(i)(A):

   Flooring or its backing shall not be sanded.

   OSHA 29 CFR 1926.1101, web page²

3. The plan is to rip it up, sweep it dry, or chip it out. OSHA’s standard says:

   Rip-up of resilient sheet floor material is prohibited.

   OSHA 29 CFR 1926.1101, web page²

   Dry sweeping is prohibited.

   OSHA 29 CFR 1926.1101, web page²

   Mechanical chipping is prohibited unless performed in a negative pressure enclosure which meets the requirements of paragraph (g)(5)(i) of this section.

   OSHA 29 CFR 1926.1101, web page²

4. The samples were taken by someone without asbestos training and accreditation. EPA’s recommendation is under What a valid report looks like.

Questions to ask the installer

1. Have the old floor, its backing and the adhesive under it been tested for asbestos? Can I see the lab results?
2. Who took the samples, and what is their asbestos training and accreditation?
3. If the material was not tested, how will you remove it, and does that follow OSHA’s rules for flooring?
4. Will any part of the removal involve sanding, dry sweeping or mechanical chipping?
