Asbestos hazards are addressed in specific standards for the construction industry.


This section highlights OSHA standards, Federal Register notices (rules, proposed rules), directives (instruction to OSHA staff), letters of interpretation (official letters of interpretation of the standards), and national consensus standards related to asbestos.


State Standards

There are twenty-eight OSHA-approved State Plans, operating state-wide occupational safety and health programs. State Plans are required to have standards and enforcement programs that are at least as effective as OSHA's and may have different or more stringent requirements.

Construction Industry (29 CFR 1926)

  • 1926 Subpart Z, Toxic and hazardous substances
    • 1926.1101, Asbestos
      • Appendix A, OSHA reference method - Mandatory
      • Appendix B, Sampling and analysis - Non-mandatory
      • Appendix C, Qualitative and quantitative fit testing procedures - Mandatory
      • Appendix D, Medical questionnaires; Mandatory
      • Appendix E, Interpretation and classification of chest roentgenograms - Mandatory
      • Appendix F, Work practices and engineering controls for class I asbestos operations - Non-mandatory
      • Appendix G, [Reserved]
      • Appendix H, Substance technical information for asbestos - Non-mandatory
      • Appendix I, Medical surveillance guidelines for asbestos, non-mandatory
      • Appendix J, Smoking cessation program information for asbestos, Non-mandatory
      • Appendix K, Polarized light microscopy of asbestos - Non-mandatory
  • For additional information on specific state plans or other general standards, see the general industry Asbestos page.

Federal Register Notices

  • Assigned Protection Factors; Final Rule. Final Rules 71:50121-50192, (August 24, 2006). Revises the existing Respiratory Protection Standard to add definitions and requirements for Assigned Protection Factors (APFs) and Maximum Use Concentrations (MUCs). The revisions also supersede the respirator selection provisions of existing substance-specific standards, including the Asbestos Standards, with these new APFs.
  • Technical Amendments. Final Rules 71:16669-16675, (April 3, 2006).
  • Search all available federal register notices.

National Consensus

Note: These are NOT OSHA regulations. However, they do provide guidance from their originating organizations related to worker protection.

American National Standards Institute (ANSI)/American Society for Testing and Materials (ASTM)

  • ASTM E1368-14 (2014), Standard Practice for Visual Inspection of Asbestos Abatement Projects. Establishes accepted practices for evaluating asbestos abatement projects.
  • ASTM E2356-14 (2014), Standard Practice for Comprehensive Building Asbestos Surveys. This practice describes procedures for conducting comprehensive surveys of buildings and facilities for the purpose of locating, identifying, quantifying, and assessing asbestos-containing materials.
  • ASTM E2394-11 (2011), Standard Practice for Maintenance, Renovation and Repair of Installed Asbestos Cement Products. This practice describes work practices for asbestos-cement products when maintenance, renovation, and repair are required. This includes common tasks such as drilling and cutting holes in roofing, siding, pipes, etc. that can result in exposure to asbestos fibers if not done carefully.
Evaluating and Controlling Exposure
  • The Asbestos Advisor. OSHA Expert Systems. Provides interactive compliance assistance. Once installed on your PC, it can interview you about buildings and worksites, and the kinds of tasks workers perform there. It will produce guidance on how the Asbestos Standard may apply to those buildings.

Medical surveillance

Medical surveillance guidance is provided in the following appendix to the OSHA Standards:

Exposure monitoring

Exposure monitoring samples must be analyzed by Phase Contrast Microscopy (PCM) for OSHA purposes. PCM methods accurately assess fiber exposure levels, but PCM can not differentiate between asbestos and non-asbestos fibers. Transmission Electron Microscopy (TEM) methods may be used to identify fibers, but may not be used to quantify air concentrations for occupational exposure.

Bulk sample analysis

Bulk sample analysis should be done by Polarized Light Microscopy (PLM). Bulk analysis results will likely apply to both OSHA and EPA regulations.
