Current through June 17, 2024
019.01
FLOORING, SIDING,
				ROOFING.
Asbestos projects, other than Asbestos Related Demolition
				Projects regulated under 178 NAC 22-017, that involve only asbestos containing
				material floor tile, sheet flooring, shingles, or siding, may be performed
				using the work practice requirements set out in 178 NAC 22-019. Projects
				involving asbestos containing material floor tile, sheet flooring, shingles, or
				siding, require notification in accordance with 178 NAC 22-007 whether
				performed in a friable or non-friable manner.
019.01(A)
PROJECTS PERFORMED IN A
				NON-FRIABLE MANNER.
For a project to not be regulated other than
				notification to the Department under 178 NAC 22-007, it must be performed in a
				manner to ensure the material does not become friable. Any process that cuts,
				crushes, grinds, abrades, pulverizes, or burns, including dropping from a
				height, will make non-friable asbestos material friable and regulated, if an
				amount of non-friable asbestos containing material that equals three square
				feet becomes friable, discontinue removal activity immediately until all
				surfaces in the work area that possibly have become contaminated with asbestos
				containing material have been cleaned thoroughly with a high efficiency
				particulate air filter-equipped vacuuming device or by wet cleaning methods. An
				amendment to any notification previously submitted to the Department must be
				made, any applicable fee paid, and the project must be performed in accordance
				with this chapter.
019.01(B)
PROJECTS PERFORMED IN A FRIABLE MANNER.
If a project
				will be performed in a friable manner, only the following requirements will
				apply to the licensed or waivered business entity or licensed individual:
(i) For indoor projects:
(1)
Security:
Establish general security and management work practices in accordance with 178
				NAC 22-010;
(2)
Containment:
(a)
				Seal airtight each window, door and other direct opening between the work area
				from which asbestos containing material is to be removed and other areas of the
				structure which are not to be impacted;
(b) Use and securely fasten plastic sheeting
				not less than 6 mil thick extending up the wall no less than four feet around
				the perimeter of the work area as a splash guard; and
(c) Install and operate high efficiency
				particulate air filter-equipped ventilation fans so that air will be discharged
				continually from all locations within the work area for all projects equal to
				or greater than 260 linear feet or any combination which is equal to or greater
				than 160 square feet and linear feet;
(3)
Decontamination:
(a) For worker protection use a double suit
				and air-lock decontamination method; and
(b) Tools are not required to be kept in the
				work area but must be cleaned and free of all visible residue or sealed in 6
				mil plastic before removal from the work area;
(4)
Removal:
Remove
				and maintain asbestos containing material in an adequately wet condition to
				prevent the release of any fibers;
(5)
Disposal:
After
				removal of the asbestos containing material, and clearance if required under
				178 NAC 22-019.01(B)(6), is complete, disassemble the containment area and
				ensure that the surfaces of all structures, furnishings, equipment and fixtures
				are free of all visible residue, including any which existed prior to the start
				of the project; except mastic which is to remain and be covered with material.
				Treat all removed plastic sheeting, all filters, waste and debris as asbestos
				containing material and dispose of in accordance with 178 NAC 22-020;
				and
(6)
Clearance:
For projects which are equal to or greater
				than 260 linear feet or any combination which is equal to or greater than 160
				square feet and linear feet, have a third party, in accord with 178 NAC 22-022,
				perform final clearance air sampling after the work area is dry. Retain the
				airtight seals for the containment area in place and operate the associated
				high efficiency particulate air filter-equipped ventilation fans until the
				results of clearance air sampling under Phase Contrast Microscopy show that the
				airborne contamination level within the work area is not greater than 0.01
				fibers per cubic centimeter as determined by the NIOSH 7400 method or not
				greater than 70 structures per square millimeter as determined by the
				Environmental Protection Agency Transmission Electron Microscopy method;
				and
(ii) For outdoor
				projects:
(1)
Security:
Establish general security and management
				work practices in accordance with 178 NAC 22-010;
(2)
Containment:
To
				preclude spread of contamination to nearby indoor areas, securely cover each
				door, window, ventilation duct or other opening into such areas within 25 feet
				of the work area with plastic sheeting not less than six mil thick;
(3)
Decontamination:
(a) For worker protection use a disposable
				coveralls and half-face respirator; and
(b) Tools must be cleaned and free of all
				visible residue or sealed in 6 mil plastic before removal from the work
				area;
(4)
Removal:
Remove and maintain asbestos containing
				material in an adequately wet condition to prevent the release of any fibers;
				and
(5)
Disposal:
After removal of the asbestos containing
				material is complete, ensure that the surfaces of all structures, furnishings,
				equipment and fixtures are free of all visible residue, including any which
				existed prior to the start of the project. Treat all removed plastic sheeting,
				all filters, waste and debris as asbestos containing material and dispose of in
				accordance with 178 NAC 22-020.
