29 CFR 1910.1001: OSHA Asbestos in General Industry

Regulatory citation: 29 CFR 1910.1001, Asbestos (General Industry)

What Is the OSHA Asbestos Standard for General Industry?

Section 1910.1001 covers occupational exposure to asbestos in general industry. It applies to work such as brake and clutch repair, building maintenance and custodial work, and handling asbestos-containing products. Construction work is covered by 29 CFR 1926.1101, and shipbuilding, ship repair and shipbreaking by 29 CFR 1915.1001.

Why the Asbestos Standard Matters

Asbestos fibers released from damaged or disturbed material can cause asbestosis, lung cancer and mesothelioma. Many older buildings still contain asbestos insulation, flooring and surfacing material that maintenance staff work around every day.

Core Obligations

1. Stay Within the Exposure Limits (1910.1001(c))

No employee may be exposed above 0.1 fiber per cubic centimeter of air (f/cc) as an 8-hour time-weighted average (TWA). The excursion limit is 1.0 f/cc averaged over 30 minutes.

2. Monitor Exposure (1910.1001(d))

Initial monitoring is required for employees who are, or may reasonably be expected to be, exposed at or above the TWA or excursion limit. Periodic monitoring must be done at intervals of no more than 6 months for those employees. Monitoring may stop when results statistically show exposure below both limits. Employees must be told their results within 15 working days after the employer receives them, with a description of corrective action where a limit was exceeded.

3. Set Up Regulated Areas (1910.1001(e))

Areas where concentrations exceed, or can reasonably be expected to exceed, a limit must be demarcated and limited to authorized persons. Respirators are required inside, and eating, drinking, smoking, chewing tobacco or gum and applying cosmetics are banned.

4. Use Engineering Controls and Safe Work Practices (1910.1001(f))

Engineering and work practice controls must be used to meet the limits where feasible, supplemented by respirators. Compressed air may not be used to remove asbestos unless it is used with a ventilation system that captures the dust cloud. Employee rotation may not be used to achieve compliance. Where a limit is exceeded, a written compliance program is required. Brake and clutch work must follow the methods in Appendix F.

5. Provide Respirators, Clothing and Hygiene Facilities (1910.1001(g) to (i))

Respirators must be used under a program that meets 29 CFR 1910.134. Filtering facepiece respirators may not be used for asbestos. Where exposure exceeds a limit, employers must provide protective clothing at no cost, replaced with clean clothing at least weekly, plus change rooms with two separate lockers, showers at the end of the shift and lunchrooms with positive pressure, filtered air.

6. Identify Asbestos in Buildings (1910.1001(j))

Building and facility owners must determine the presence, location and quantity of asbestos-containing material (ACM) and presumed asbestos-containing material (PACM). PACM means thermal system insulation and surfacing material in buildings built no later than 1980. Owners must keep these records for as long as they own the building and pass them to the next owner. Signs are required at regulated areas and at entrances to mechanical rooms that contain ACM or PACM, and labels are required on asbestos products and waste.

7. Follow Housekeeping Rules (1910.1001(k))

Surfaces must be kept as free as practicable of ACM waste, debris and dust. HEPA vacuums must be used for asbestos debris, and compressed air may not be used for cleaning. Sanding asbestos-containing flooring is banned. Stripping floor finish must use wet methods and low-abrasion pads at speeds below 300 rpm.

8. Train, Provide Medical Surveillance and Keep Records (1910.1001(j)(7), (l) and (m))

Employees exposed at or above a limit must be trained at initial assignment and at least annually. Housekeeping staff working in areas with ACM or PACM must get annual awareness training at no cost. Medical exams are required for employees exposed at or above a limit, before placement, annually and within 30 calendar days before or after termination. Exposure records must be kept for at least 30 years, medical records for the duration of employment plus 30 years, and training records for 1 year after employment ends.

Common Compliance Approaches

Keep an Asbestos Register

Map every known and presumed asbestos location in the building, and check it before issuing any maintenance work order.

Set Floor Care Rules

Write a floor care procedure for asbestos flooring that sets pad type, machine speed and wet methods, and train custodians on it.

Example: Asbestos Management in Practice

A manufacturing company owns a plant built in 1965 with pipe insulation in its boiler room. It treats the insulation as PACM, records its location and posts signs at the boiler room doors. Custodians receive annual awareness training on where the material is and how to spot damage. When a section of lagging is found damaged, the company stops work in the area and calls a licensed abatement contractor, which works under the construction asbestos standard.

Note: In July 2025 OSHA proposed changes to the respirator provisions of its asbestos standards. OSHA reopened the comment period in July 2026 and held public hearings in August 2026. No final rule had been issued as of October 2026, so check for updates. State plan states may set stricter rules.

Frequently Asked Questions

Does this standard cover asbestos removal projects?

No. Removal, renovation and demolition are construction work under 29 CFR 1926.1101. This standard covers general industry activities such as maintenance, custodial work and brake and clutch repair.

What is PACM?

Presumed asbestos-containing material. It means thermal system insulation and surfacing material in buildings built no later than 1980, treated as asbestos unless shown otherwise.

Can I use a disposable N95 for asbestos?

No. The standard says employers must not select or use filtering facepiece respirators for protection against asbestos fibers.
