What "disturb" means

To disturb asbestos-containing material means to disrupt its matrix, crumble or pulverize it, or generate visible debris from it. Drilling, cutting, sanding, scraping or breaking it all do that. If you are not trained and assigned for that class of asbestos work, do not do it.

Class IV work: contact without disturbing

Maintenance and custodial work where you contact but do not disturb ACM or PACM, and cleaning up dust, waste and debris from asbestos jobs, is Class IV work. It must be done by employees with asbestos awareness training, using wet methods, HEPA vacuums and prompt clean-up of debris.

Construction: prohibited for asbestos work, whatever the measured levels

Dry sweeping, shoveling or other dry clean-up of dust and debris containing ACM or PACM
Compressed air to remove asbestos, unless used with an enclosed ventilation system that captures the dust cloud

General industry housekeeping

Surfaces contaminated with asbestos may not be cleaned with compressed air. This rule has no enclosed-system exception.
HEPA-filtered vacuums must be used for vacuuming asbestos-containing waste and debris.
Shoveling, dry sweeping and dry clean-up of asbestos may be used only where vacuuming and/or wet cleaning are not feasible.
Waste, debris and dust in an area with accessible ACM or PACM, or visibly deteriorated ACM, must not be dusted or swept dry, or vacuumed without a HEPA filter.

Floors

Asphalt and vinyl flooring installed no later than 1980 must be treated as asbestos-containing unless shown otherwise. In construction, the flooring care rules apply to all vinyl and asphalt flooring unless the building or facility owner demonstrates that it does not contain asbestos; in general industry, they apply to asbestos-containing flooring.

Sanding is prohibited.
Stripping of finishes must use low abrasion pads at speeds lower than 300 rpm and wet methods.
Burnishing or dry buffing is allowed only on flooring with enough finish that the pad cannot contact the flooring material.
