4. Airlock: system for permitting entrance and exit while restricting air movement between a contaminated area and an uncontaminated area. It consists of two curtained doorways separated by a distance of at least three feet such that one passes through one (1) doorway into the airlock, allowing the doorway sheeting to overlap and close off the opening before proceeding through the second doorway, thereby preventing flow-through contamination.

5. Air Sampling: Process of measuring the fiber content of a known volume of air collected during a specific period. The procedure utilized for asbestos follows the NIOSH Standard Analytical Method 7400, or the provisional transmission electron microscopy methods developed by the US EPA, which are utilized for lower detection levels and specific fiber identification.

16. Asbestos Inspection Report: A report on the condition of a building or structure in relation to the presence and condition of asbestos therein.

17. Asbestos Project: Any form of work performed in connection with the alteration, innovation, modification, or demolition of a building or structure which will disturb (e.g. remove, enclose, encapsulate) more than three linear feet or more than three square feet of friable ACM.

19. Barrier: Polyethylene sheeting that completely seals off the work area to prevent contamination of the surrounding area.

20. Building Owner: Person in whom legal title to the premises is vested unless the premises are held in land trust, in which instance Building Owner means the person in whom beneficial title is vested.

21. Clean Room: An uncontaminated area or room that is part of worker decontamination enclosure system with provisions for storage of workers’ street clothes and protective equipment.

May 29, 2019 028213 - 10

22. Clearance Air Monitoring: Employment of aggressive sampling techniques with a volume of air collected to determine the airborne concentration of residual fibers and shall be performed as the final abatement activity.

23. Construction Permit for Asbestos Abatement: A required permit provided by the jurisdictional Buildings Department for the approval to commence any asbestos hazard abatement.

24. Contractor: The hazardous material removal contractor licensed to remove Asbestos.

25. Critical Barrier: Two (2) layers of 6–mil polyethylene sheeting that completely seals off the work area to prevent the distribution of fibers to the surrounding area, such as the opening between the top of non-movable lights, HVAC systems, windows, doors, ducts, grills, electrical outlets, floor drains, sinks, etc.

26. Curtained Doorway: Device that consists of at least three overlapping sheets of polyethylene over an existing or temporarily framed doorway. One (1) sheet shall be secured at the top and left side, the second sheet at the top and right side, and the third sheet at the top and left side. All sheets shall have weights attached to the bottom to ensure that the sheets hang straight and maintain a seal over the doorway when not in use.

27. Decontamination Enclosure System: Series of connected rooms, separated from the Work Area and from each other by air locks, for the decontamination of workers, materials, waste containers, and equipment.
