Definition
Procedures to control the release of asbestos fibers from asbestos-containing materials, including removal, encapsulation, enclosure, or repair. Abatement must be performed by licensed contractors following strict safety protocols including containment, negative air pressure, worker protection, and proper disposal. The goal is to eliminate or minimize asbestos exposure risk to building occupants and workers.

Asbestos
A group of naturally occurring fibrous minerals composed of thin, needle-like fibers. Asbestos was widely used in construction and manufacturing due to its heat resistance, strength, and insulating properties. When disturbed, asbestos releases microscopic fibers that can be inhaled, causing serious health problems including lung cancer, mesothelioma, and asbestosis. All types of asbestos are now recognized as carcinogenic.
Containment
An enclosed work area constructed with polyethylene sheeting and sealed to prevent the escape of asbestos fibers during removal work. Containment includes critical barriers, airlocks, decontamination units, and negative air pressure systems. The integrity of containment must be maintained throughout the project and verified through air monitoring and visual inspections.
