Chemical-Specific Standards
(OSHA 29 CFR 1926.1101-1153 & 1910.1001-1053: Asbestos and Silica)
Why This Matters
OSHA uses chemical-specific standards because some substances can cause serious long-term health effects, even at low exposure levels. These requirements call for controls, monitoring, PPE, and training to help prevent chronic illness, cancer, and fatal lung disease.
Key Chemical-Specific Standards in Construction
1. Asbestos – 29 CFR 1926.1101 / 1910.1001
Major Hazards
- Lung cancer, mesothelioma, and asbestosis
- Fibers released when old insulation, flooring, mastics, or roofing materials are cut, ground, demolished, or otherwise disturbed
Core Requirements
- Conduct exposure assessments and establish regulated areas
- Provide oversight by a competent person
- Use HEPA-filtered ventilation and wet methods
- Prohibit dry sweeping and compressed air
- Provide medical surveillance for exposed workers
- Require respiratory protection and protective clothing
- Dispose of waste in sealed, labeled containers
2. Respirable Crystalline Silica – 29 CFR 1926.1153
Major Hazards
- Silicosis (incurable), lung cancer, COPD, and kidney disease
- Dust generated when cutting, drilling, grinding, jackhammering, or sweeping concrete, masonry, stone, or tile
Core Requirements
- Use Table 1 controls or perform exposure monitoring
- Use water delivery systems or shrouded tools with HEPA vacuums
- Maintain a written exposure control plan
- Assigning a competent person
- Restrict access to high-dust areas
- Use respiratory protection when controls cannot keep exposure below the PEL
Training Requirements
Workers must be trained before exposure and annually when required by the standard. Training must cover:
- Health effects of the chemical
- Tasks that create exposure
- Engineering controls and safe work practices
- Correct respirator use, fit testing, and limitations
- Decontamination and hygiene procedures
- Emergency procedures and spill response
- Labeling, SDS access, and regulated area requirements
Engineering & Work Practice Controls
- Use wet methods to reduce dust
- Clean with HEPA-filtered vacuums
- Do not dry sweep or use compressed air
- Use local exhaust ventilation on tools
- Enclose or isolate high-exposure tasks
- Follow Table 1 for silica work
- Maintain negative-pressure enclosures for asbestos work
- Handle and label waste properly
Signs of Overexposure
Workers should report the following symptoms immediately:
- Persistent cough or shortness of breath
- Chest tightness or wheezing
- Skin irritation or rashes
- Eye or throat irritation
- Unusual fatigue
- Metallic taste (lead or chromium)
- Nosebleeds or sinus irritation (silica or chromium)
Decontamination & Housekeeping
- Do not track dust into clean areas
- Use designated changing areas for asbestos or silica work
- Dispose of contaminated PPE properly
- Wash hands and face before eating, drinking, or smoking
- Use only HEPA vacuums or wet-cleaning methods
Key Takeaways for the Crew
- These standards exist because the health effects can be permanent and often fatal.
- Only certified Asbestos Abatement companies may disturb or work with Asbestos Containing Material (ACM)
- Most exposures can be prevented with controls, PPE, and safe work practices.
- If you see dust, debris, or suspect materials, stop and notify the competent person.
- Do not disturb suspect materials, including asbestos, lead, or silica-containing products, without proper controls.
