(a) Requirements for employees performing Class I asbestos jobs involving over twenty-five linear or ten square feet of TSI or surfacing ACM and PACM.

(i) Decontamination areas: The employer must establish a decontamination area that is adjacent and connected to the regulated area for the decontamination of such employees. The decontamination area must consist of an equipment room, shower area, and clean room in series. The employer must ensure that employees enter and exit the regulated area through the decontamination area.

(A) Equipment room. The equipment room must be supplied with impermeable, labeled bags and containers for the containment and disposal of contaminated protective equipment.

(B) Shower area. Shower facilities must be provided which comply with WAC 296-800-230, unless the employer can demonstrate that they are not feasible. The showers must be adjacent both to the equipment room and the clean room, unless the employer can demonstrate that this location is not feasible. Where the employer can demonstrate that it is not feasible to locate the shower between the equipment room and the clean room, or where the work is performed outdoors, the employers must ensure that employees:

(I) Remove asbestos contamination from their worksuits in the equipment room using a HEPA vacuum before proceeding to a shower that is not adjacent to the work area; or

(II) Remove their contaminated worksuits in the equipment room, then don clean worksuits, and proceed to a shower that is not adjacent to the work area.

(C) Clean change room. The clean room must be equipped with a locker or appropriate storage container for each employee's use.

(ii) Decontamination area entry procedures. The employer must ensure that employees:

(A) Enter the decontamination area through the clean room;

(B) Remove and deposit street clothing within a locker provided for their use; and

(E) After showering, employees must enter the clean room before changing into street clothes.

(b) Requirements for Class I work involving less than twenty-five linear or ten square feet of TSI or surfacing ACM and PACM, and for Class II and Class III asbestos work operations where exposures exceed a PEL or where there is no negative exposure assessment produced before the operation.

(i) The employer must establish an equipment room or area that is adjacent to the regulated area for the decontamination of employees and their equipment which is contaminated with asbestos which must consist of an area covered by a impermeable drop cloth on the floor or horizontal working surface.

(ii) The area must be of sufficient size as to accommodate cleaning of equipment and removing personal protective equipment without spreading contamination beyond the area (as determined by visible accumulations).

(iii) Work clothing must be cleaned with a HEPA vacuum before it is removed.

(iv) All equipment and surfaces of containers filled with ACM must be cleaned prior to removing them from the equipment room or area.

(v) The employer must ensure that employees enter and exit the regulated area through the equipment room or area.

(c) Requirements for Class IV work. Employers must ensure that employees performing Class IV work within a regulated area comply with hygiene practice required of employees performing work which has a higher classification within that regulated area.

(e) Waste load-out procedure. The waste load-out area as required by WAC 296-62-07723 must be used as an area for final preparation and external decontamination of waste containers, as a short term storage area for bagged waste, and as a port for transporting waste. The employer must ensure waste containers be free of all gross contaminated material before removal from the negative-pressure enclosure. Gross contamination must be wiped, scraped off, or washed off containers before they are placed into a two chamber air lock which is adjacent to the negative-pressure enclosure. In the first chamber, the exterior of the waste container must be decontaminated or placed within a second waste container, and then it must be moved into the second chamber of the air lock for temporary storage or transferred outside of the regulated area. The second waste container must not be reused unless thoroughly decontaminated.
