178 Neb. Admin. Code, ch. 22, § 019

Current through May 7, 2024

Section 178-22-019 - WORK PRACTICES TO BE FOLLOWED FOR PROJECTS INVOLVING ASBESTOS CONTAINING MATERIAL FLOOR TILE, SHEET FLOORING, SHINGLES, OR SIDING

019.01FLOORING, 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.
