Study Notes

Key Terms and Definitions

Presumed Asbestos Containing Material (PACM): Thermal system insulation and surfacing material identified in buildings constructed prior to 1980.
Construction Work: Encompasses construction, alteration, and repair activities, including painting and decorating, as defined by OSHA.
Asbestos Identification: Includes chrysotile, amosite, crocidolite, tremolite, anthophyllite, actinolite, and PACM.
Asbestos Containing Material (ACM): Any material containing more than 1% asbestos.
Aggressive Method: Removal techniques that break, grind, or disturb intact ACM, leading to its disintegration.

Work Classifications

Class I Asbestos Work: Involves removal of thermal system insulation (TSI) and surfacing ACM and PACM.
Class II Asbestos Work: Removal of ACM materials not classified as TSI or surfacing, including wallboard and floor tiles.
Class III Asbestos Work: Repair and maintenance where ACM may be disturbed.
Class IV Asbestos Work: Maintenance activities involving non-disturbance of ACM and clean-up of debris from other classes.

Regulatory Framework

OSHA 29 CFR 1926.1101: Regulates asbestos exposure in various construction scenarios, including demolition, maintenance, and emergency clean-up.
Permissible Exposure Limits (PELs):
- Time-weighted average limit: 0.1 fibers per cubic centimeter over 8 hours.
- Excursion limit: 1.0 fiber per cubic centimeter averaged over 30 minutes.

Safety Protocols

Competent Person: An individual who identifies asbestos hazards and implements control strategies, possessing the necessary training and authority.
Clean Room: An uncontaminated area for storing personal street clothing and uncontaminated materials.
Critical Barrier: Sealing barriers that prevent airborne asbestos from migrating from a regulated work area.

Decontamination and Waste Management

Decontamination Area: A controlled space for cleaning workers and equipment contaminated with asbestos.
Equipment Room: Contains items for disposing of contaminated clothing and materials.

Prohibitions and Working Methods

Prohibited Activities: No eating, drinking, or using cosmetics in regulated areas to prevent asbestos exposure.
Engineering Controls: Use of HEPA vacuums, wet methods, and other local exhaust systems designed to minimize airborne asbestos.

Exposure Management

Negative Initial Exposure Assessment: Employers must demonstrate that employee exposure will remain below PELs.
Disturbance Definition: Activities causing disruption to ACM/PACM that could generate visible debris or airborne fibers.

Clean-Up and Maintenance

Removal Definition: Operations involving the extraction of ACM from structures.
Renovation: Modifying an existing structure may involve ACM-related work.
Repair Definition: Overhauling or reconstructing materials, including maintenance of ACM.

Hazardous Materials Characteristics

Fiber Specifications: Defined as asbestos particulates longer than 5 micrometers with a 3:1 length to diameter ratio.
Homogeneous Area: An area of ACM that has a uniform appearance in color and texture.

These bullet points cover crucial aspects of OSHA’s 29 CFR 1926.1101 Asbestos Construction Industry Standard, providing concise insights into the regulations surrounding asbestos in construction work.
