Current through Register Vol. 48, No. 28, July 12, 2024
The contractor shall construct or provide a worker
				  decontamination enclosure system in accordance with the following:
a) Worker decontamination enclosure systems
				shall be provided at all locations where workers will enter or exit the work
				area. These systems may consist of existing rooms outside of the work area, if
				the layout is appropriate, that can be enclosed in plastic sheeting and are
				accessible from the work area. When this situation does not exist, enclosure
				systems may be constructed out of metal, wood or plastic support as
				appropriate, or a portable unit may be utilized (see Appendix A, Illustration
				D).
b) Worker decontamination
				enclosure systems constructed at the worksite of plastic sheeting installed
				over a framework shall utilize six mil opaque polyethylene or equivalent
				strength sheeting.
c) The worker
				decontamination enclosure system shall consist of at least a clean room, a
				shower room, and an equipment room, separated from each other by
				airlocks.
d) Entry to and exit from
				all airlocks and decontamination enclosure system chambers shall be through
				curtained doorways.
e) Access
				between any two rooms in the decontamination enclosure system shall be through
				an airlock with at least three feet separating each curtained doorway. Pathways
				into (from clean to contaminated) and out from (contaminated to clean) the work
				area shall be clearly designated.
f) The clean room shall be sized to
				accommodate the clothes and equipment of the work crew. Benches shall be
				provided, as well as hooks for hanging up street clothes. Lockers may be
				provided for valuables; however, workers may be requested to secure valuables
				elsewhere. Shelves for storing respirators shall also be provided in this area.
				Clean work clothes (if required under disposables), clean disposable clothing,
				replacement filters for respirators, towels and other necessary items shall be
				provided in the clean room. A location for postings shall also be provided in
				this area. A lockable door shall be used to permit access into the clean room
				from outside the work area. This space shall not be used for storage of tools,
				equipment, or materials, or as office space.
g) The shower room shall contain one or more
				showers to accommodate workers. Each shower head shall be supplied with hot and
				cold water adjustable at the tap. The shower enclosure shall be constructed to
				ensure against leakage of any kind. Soap, shampoo and towels shall be supplied
				by the contractor and shall be available at all times. Shower water shall be
				drained, collected and filtered through a system with at least 5.0 micron
				particle size collection capability. A system containing a series of several
				filters with progressively smaller pore sizes shall be used to avoid rapid
				clogging of the filtration system by large particles. Filtered wastewater shall
				be discharged to a sanitary sewer.
h) The equipment room shall be used for
				storage of equipment and tools at the end of a shift after decontamination
				using a HEPA filtered vacuum and/or wet cleaning techniques. Replacement
				filters (in sealed containers until used) for HEPA vacuums and negative
				pressure ventilation equipment, extra tools, containers of surfactant and other
				materials and equipment that may be required during the abatement may also be
				stored here as needed. A labeled six mil polyethylene or equivalent bag for
				collection of disposable clothing shall be located in this room. Contaminated
				footwear (e.g., rubber boots and other reusable footwear) shall be stored in
				this area for reuse.
