A. AGGRESSIVE AIR SAMPLES – Air samples collected after floors, ceiling, and walls of the work area have been swept with the exhaust of a one (1) horsepower leaf blower. Area air shall be agitated each hour while such samples are being collected.

B. AMENDED WATER – Amended water contains a surfactant or wetting agent, creating a solution with which asbestos fibers bond easily.

C. ASBESTOS – The term asbestos includes chrysotile, amosite, crocidolite, tremolite, anthophyllite, and actinolite.

D. ASBESTOS FIBERS – This expression refers to asbestos fibers having an aspect ratio of 3:1 and longer than 5 micrometers.

E. ASBESTOS-SAFE – Asbestos present in a building that has been rendered non-hazardous by means of encapsulation or enclosure or has been determined to be non-friable.

F. AUTHORIZED VISITORS – Any visitor authorized by Owner or any representative of a regulatory agency or other agency having jurisdiction over the project.

G. CONTAINMENT AREA – A portion of the regulated area that has been sealed and placed under negative air pressure using negative air machines with HEPA filters.

H. DECONTAMINATION FACILITIES – A series of connected rooms, with airlocks of curtained doorways between any two adjacent rooms, for the decontamination of workers or of materials and equipment. Decontamination systems shall be contiguous and adjacent to the enclosed asbestos control area.
