OSHA’s asbestos standard for construction — 29 CFR 1926.1101 — tells you what the rules are. This post covers what you actually have to do to comply with them on a jobsite: the programs, people, equipment, and procedures a construction company needs to have in place before work begins on any project where asbestos-containing materials may be present.
For a detailed breakdown of the regulatory framework itself — NESHAP, OSHA, Georgia EPD, and South Carolina DHEC requirements — see our post on asbestos regulations for Georgia and South Carolina projects.
Why construction workers face ongoing asbestos risk
Asbestos was used extensively in commercial and residential construction from the 1930s through the late 1970s. Restrictions on new applications took effect progressively through federal EPA regulations from 1973 onward, but those restrictions applied to new installations — they did not require removal of asbestos already in place. As a result, a substantial portion of the commercial and industrial building stock in the Augusta area and across the CSRA still contains asbestos-containing materials in some form.
Construction workers encounter this legacy asbestos not primarily during formal abatement projects, but during routine renovation and repair work — replacing flooring, opening ceilings for HVAC access, repiping, electrical upgrades, and demolition. Workers who do not know they are working near asbestos, and who have not been trained or equipped for that exposure, are the population OSHA 1926.1101 was written to protect.
The written asbestos compliance program
Any construction employer whose workers may perform Class I or Class II asbestos work must have a written asbestos compliance program in place before that work begins. This is not optional — OSHA 1926.1101(g) requires it for regulated work. The program must be available at the worksite and must cover:
- A description of the work operations that will be performed and the class of work involved
- The engineering controls and work practices to be used
- The respiratory protection program, including respirator selection and fit-testing procedures
- The housekeeping procedures to be followed
- Medical surveillance enrollment procedures for qualifying employees
- The identity of the competent person and their responsibilities
- Training procedures and schedules for workers performing each class of work
- How the employer will conduct initial and periodic exposure assessments
For smaller contractors performing occasional Class III or Class IV work, a less formal written program covering the relevant work practices and training documentation is still expected. OSHA inspectors look for evidence that the employer has actually thought through asbestos management — not just a generic template downloaded from the internet.
The competent person: the most important role on an asbestos jobsite
OSHA requires a designated competent person for all asbestos construction work. This is not an administrative checkbox — the competent person is the individual responsible for worker safety on the ground, and their presence and judgment are the mechanism through which most other OSHA requirements get implemented.
The OSHA definition of a competent person for asbestos is specific: someone who is capable of identifying existing and predictable asbestos hazards in the work environment and who has the authority to take prompt corrective measures to eliminate them. For Class I and II work, the competent person must be present continuously on-site — not available by phone, not checking in periodically.
What the competent person must be able to do:
- Identify all materials in the work area that are or may be ACM or PACM
- Establish and clearly mark regulated areas before work begins
- Verify that containment is properly constructed and negative pressure is maintained
- Conduct daily visual inspections of all containment barriers and decontamination facilities
- Verify that all workers in regulated areas are wearing correct respiratory protection and PPE
- Oversee or conduct air monitoring and evaluate results against the action level and PEL
- Authorize or direct immediate corrective action — including stopping work — when a hazard is identified
- Ensure proper labeling and disposal of asbestos waste
Competent person qualifications: For Class I and II work, the competent person must hold current training equivalent to EPA/AHERA Inspector or Supervisor accreditation, which requires a 5-day initial course plus annual 1-day refresher. For Class III work, a 16-hour operations and maintenance course satisfies the requirement. For Class IV custodial work, a 2-hour awareness course is the minimum.
Worker training requirements by work class
OSHA specifies minimum training content and duration for each class of asbestos work. These are floors, not ceilings — additional training is always appropriate.
Class I and II work: Workers must have completed an EPA/AHERA Operations and Maintenance (O&M) course covering asbestos hazards, health effects, exposure controls, PPE, decontamination, and emergency procedures. Initial training is 16 hours; annual refresher is required to maintain currency. Workers performing Class I removal of thermal system insulation must hold Asbestos Worker accreditation from their state — in Georgia, this means EPA/AHERA accreditation recognized by Georgia EPD.
Class III work: Workers must complete a 16-hour O&M course. The course covers how to recognize ACM and PACM, personal protective equipment, safe work practices for maintenance operations, and emergency procedures. Annual refresher required.
Class IV custodial work: Workers must complete asbestos awareness training — minimum 2 hours — covering health effects of asbestos exposure, how to recognize ACM, and the importance of not disturbing asbestos materials. This training must be provided before workers enter areas where asbestos work has occurred.
All workers: Before working in areas containing ACM or PACM, workers must receive training covering the location of ACM and PACM in their work area, the health effects of asbestos, and the specific work practices and PPE required for their assigned tasks.
Training records must be maintained for the duration of employment. If an OSHA inspector asks to see training documentation for workers on an asbestos job, the employer must be able to produce it.
Respiratory protection and PPE by work class
OSHA’s respiratory protection requirements for asbestos work are tied to the class of work and the anticipated exposure level, not just the worker’s preference.
Class I thermal system insulation removal: Supplied-air respirator (SAR) in pressure-demand mode, or full-face air-purifying respirator with P100 (HEPA) filters. For most Class I work in full containment, a half-mask respirator is not sufficient. When a negative-pressure enclosure is used and exposure monitoring demonstrates fiber levels do not exceed 1 f/cc, a half-face respirator with P100 filters is permitted, but the employer must have the monitoring data to support that decision.
Class II removal: At minimum, a half-face air-purifying respirator with P100 filters. Full-face respirator or SAR required if monitoring indicates exposures above 1 f/cc.
Class III repair and maintenance: Half-face air-purifying respirator with P100 filters as a baseline; upgrade based on exposure assessment results.
Class IV custodial: Half-face respirator with P100 filters when cleaning up asbestos debris or using HEPA vacuums in areas where asbestos work has occurred.
Beyond respiratory protection, workers in regulated areas must wear disposable full-body coveralls (Tyvek or equivalent), gloves, and boot covers. All protective clothing must be removed before leaving the regulated area and placed in sealed bags for disposal as asbestos waste — not shaken out or worn outside the work zone.
Air monitoring: who does it, when, and what triggers action
Air monitoring on asbestos construction projects serves two purposes: initial exposure assessment to determine which controls are required, and ongoing monitoring to verify that controls are working.
Initial exposure assessment: Before Class I, II, or III work begins, the employer must conduct an initial exposure assessment. This can be based on objective data — documented measurements from prior identical operations — or on initial air monitoring collected at the start of work. The assessment determines whether workers may be exposed above the action level (0.1 f/cc) and guides respirator selection and engineering control decisions.
During work: For Class I work, air monitoring inside the containment and in the area immediately outside must be conducted periodically. For Class II and III work, periodic monitoring is required when the employer does not have objective data demonstrating that the work will not exceed the action level.
Clearance sampling: After abatement work is complete and visible debris has been removed, clearance air sampling must confirm that fiber concentrations in the work area are within acceptable limits before the containment is broken down and other workers re-enter. Clearance sampling is conducted using aggressive sampling protocols — fans agitate the air during sampling to simulate realistic conditions.
Air monitoring must be conducted by a qualified person. For clearance sampling following Class I abatement, many projects require an independent third-party industrial hygienist. Document all monitoring results — date, location, sampling method, results, and name of the person who collected samples — and retain records for 30 years per OSHA requirements.
Pre-task planning: what to do before work begins
The best time to identify asbestos hazards is before workers are on the tools, not after. Pre-task planning for any project in a pre-1980 building should include:
- Review the building’s asbestos survey. Before mobilizing, obtain the current asbestos survey from the building owner. OSHA requires building owners to provide survey results to contractors before work begins. If no survey exists, the contractor should require one before bidding — or factor the cost of pre-task sampling into the scope.
- Identify PACM in the work area. Any pre-1981 thermal system insulation and surfacing material must be treated as asbestos-containing unless the survey proves otherwise. Walk the work area with the survey report in hand before any tools are deployed.
- Brief all workers on ACM and PACM locations. Every worker entering the work area must know where suspect materials are, what they look like, and what to do if they encounter something unexpected.
- Establish regulated areas before starting work. For Class I and II work, regulated areas must be established, marked with warning signs, and access restricted to trained workers wearing appropriate PPE before any disturbance begins.
- Verify the competent person is on-site. For Class I and II work, the competent person must be present before work starts, not called in after the fact.
When workers unexpectedly encounter suspected ACM
Despite pre-task planning, construction workers sometimes encounter suspected asbestos-containing material that was not identified in the survey or was not expected in a particular location. The correct response is straightforward:
- Stop work in the affected area immediately
- Do not disturb the material further — set tools down, do not attempt to clean up debris
- Notify the competent person and the building owner or general contractor
- Restrict access to the area until the material has been assessed by an accredited inspector
- Document the discovery — location, what was found, what work was in progress
- Do not resume work in the area until testing confirms the material is asbestos-free or until appropriate abatement has been completed
Continuing to work after encountering suspected ACM — without stopping to assess — is one of the most common sources of OSHA citations on construction projects. It is also the scenario most likely to generate worker exposure claims years down the road.
General contractor responsibilities for subcontractors
On multi-trade projects, the general contractor has obligations that extend beyond their own workers. When a GC has the ability to correct violations and the authority to direct subcontractors on safety matters, OSHA can hold the GC responsible for subcontractor asbestos violations under the multi-employer worksite doctrine.
Practical steps for general contractors managing asbestos-related subcontractors:
- Require subcontractors to provide proof of current state accreditation (Georgia EPD or South Carolina DHEC) before mobilization
- Require subcontractors to provide their written asbestos compliance program and competent person designation in writing before work begins
- Verify that regulated areas are properly established and marked before other trades work near asbestos abatement
- Include asbestos compliance requirements in subcontract agreements — not just a general safety clause
- Coordinate sequencing so other trades do not enter abatement areas until clearance is received
What an OSHA construction site inspection looks like
OSHA inspections of asbestos construction projects are most commonly triggered by worker complaints, which can be filed anonymously through OSHA’s online portal. They also result from referrals from other agencies, including Georgia EPD and South Carolina DHEC, and from OSHA’s own programmed inspection initiatives targeting high-hazard industries.
During an inspection, the OSHA compliance officer will typically:
- Review the building’s asbestos survey and the employer’s written compliance program
- Walk the work area to verify regulated areas are established and properly marked
- Check that workers in regulated areas are wearing required respiratory protection and PPE
- Verify the competent person is on-site and can demonstrate knowledge of their responsibilities
- Review training records for workers performing Class I–IV work
- Check air monitoring records and evaluate whether monitoring frequency meets the standard
- Inspect waste containerization, labeling, and staging for disposal
Citations issued during an inspection are classified as other-than-serious, serious, willful, or repeat. Willful citations — where the employer knew of the hazard and failed to act — carry the highest penalties and become part of the company’s public OSHA inspection history, accessible to clients and project owners reviewing contractor safety records.
FAQ
Can a general contractor use a subcontractor’s competent person, or does the GC need their own?
The competent person obligation runs to the employer whose workers are performing the asbestos work. A subcontractor performing Class I abatement must provide their own competent person for their workers. The GC may rely on the subcontractor’s competent person for asbestos-specific matters in the abatement zone, but the GC retains independent responsibility for the overall safety of their workers on the site.
Our workers only do occasional Class III work — small repairs and maintenance. Do we still need a full compliance program?
Yes. OSHA 1926.1101 applies to Class III work. While the requirements are lighter than for Class I and II, you still need a designated competent person with 16-hour O&M training, workers trained to the Class III level, appropriate PPE, and an initial exposure assessment before work begins. A written program documenting your procedures for this work is expected.
How often does respiratory protection need to be fit-tested?
Under OSHA’s Respiratory Protection Standard (29 CFR 1910.134), workers must be fit-tested before using a tight-fitting respirator for the first time and annually thereafter. Fit-testing must also be repeated whenever the worker changes respirator model, style, or size, or when changes in the worker’s physical condition — significant weight change, dental work, facial scarring — could affect the respirator fit.
What records do we need to keep and for how long?
OSHA requires exposure monitoring records for 30 years from the date of measurement. Medical surveillance records must be retained for the duration of employment plus 30 years. Training records must be available during the period of employment. Written compliance programs and objective data relied upon for exposure assessments should also be retained for the duration of their applicability plus a reasonable period after project completion.
A worker on our crew thinks they were exposed to asbestos last week on a job. What are our obligations?
First, assess whether the exposure actually occurred by reviewing what materials were present and what work was performed. If exposure above the action level is possible, conduct air monitoring or consult with an industrial hygienist to evaluate the situation. If the worker has not already been enrolled in medical surveillance, evaluate whether they now qualify. Document the potential exposure event. Workers have the right to request medical examination from their employer following a potential asbestos exposure, and retaliating against a worker who raises a safety concern is a separate OSHA violation.
Does our asbestos compliance program need to be project-specific or can we use one company-wide program?
A company-wide program can establish your baseline policies and procedures, but OSHA expects it to be supplemented with project-specific information for each job: the specific materials present (from the building survey), the specific class of work to be performed, the designated competent person for that project, and the specific engineering controls and PPE to be used. A generic program with no project-specific content will not satisfy an OSHA inspector’s expectation that the program is actually implemented.
