New York Codes, Rules and Regulations › Title 12 - DEPARTMENT OF LABOR › Chapter I - Industrial Board Of Appeals › Subchapter A - The Industrial Code › Part 56 - Asbestos › Subpart 56-7 - Phase Ii A: Work Area Preparation › Section 56-7.5 - Personal and waste decontamination system enclosures

Current through Register Vol. 46, No. 28, July 10, 2024
(a) Installation. Personal decontamination
					 system enclosures shall be constructed and functional prior to commencing the
					 remainder of the Phase II A regulated abatement work area preparation
					 activities. Waste decontamination system enclosures shall be constructed and
					 functional at the completion of Phase II A preparation activities. After
					 installation of the personal decontamination system enclosure, all access to
					 the regulated abatement work area shall be via the installed personal
					 decontamination system enclosure.
(b) Personal decontamination system
					 enclosure--large project.
(1)
					 Enclosure--general. A personal decontamination system enclosure shall be
					 provided outside the regulated abatement work area and attached to all
					 locations where personnel shall enter or exit the regulated abatement work
					 area. One personal decontamination enclosure system for each regulated
					 abatement work area shall be required. This system may utilize adequate
					 existing lighting sources separate from the decontamination system enclosure,
					 or shall be supplied with a GFCI protected temporary lighting system. The
					 personal decontamination system enclosure shall be sized to accommodate the
					 number of workers and equipment required for the intended purpose. Such system
					 may consist of existing attached rooms outside of the regulated abatement work
					 area, if the layout is appropriate, that can be plasticized and are accessible
					 from the regulated abatement work area. When this situation does not exist,
					 personal decontamination enclosure systems may be constructed of metal, wood or
					 plastic supports covered with fire- retardant plastic sheeting. A minimum of
					 one layer of six mil fire-retardant plastic sheeting shall be installed on the
					 ceiling, and walls of the enclosure system. At least two layers of six mil
					 fire-retardant reinforced plastic sheeting shall be used for flooring
					 protection of this area. This system must be kept clean, sanitary and climate
					 controlled at all times in conformance with all Federal, State and local
					 government requirements. This system shall remain on-site, operational and be
					 used until completion of Phase II C of the asbestos project.
(2) Rooms and configuration. The personal
					 decontamination system enclosure shall consist of a clean room, a shower room
					 and an equipment room connected in series but separated from each other by
					 airlocks. There shall be a curtained doorway separation between the equipment
					 room and the regulated abatement work area, and there shall be a lockable door
					 to the outside. (See Figure 1 within this section.) Minimum dimensions for each
					 airlock, shower room and equipment room shall be three feet wide by six feet in
					 height, to allow for adequate access to and from the regulated abatement work
					 area.
(3) Curtained doorway. An
					 assembly which consists of at least three overlapping sheets of six mil
					 fire-retardant plastic over an existing or temporarily framed doorway. One
					 sheet shall be secured at the top and left side, the second sheet at the top
					 and right side, and the third sheet at the top and left side. All sheets shall
					 have weights attached to the bottom to insure that the sheets hang straight and
					 maintain a seal over the doorway when not in use.
(4) Framing. Enclosure systems accessible to
					 the public shall be fully framed, hard-wall sheathed and utilize a lockable
					 door for safety and security.
(5)
					 Sheathing. A plywood or oriented strand board (OSB) sheathing material of at
					 least 3/8 -inch thickness.
(6)
					 Plastic sheeting. Enclosure systems constructed at the work site shall use at
					 least one layer of six mil fire-retardant plastic sheeting on walls and
					 ceiling. At least two layers of six mil fire-retardant reinforced plastic
					 sheeting shall be used for floor protection of this area.
(7) Prefabricated or trailer units. A
					 completely watertight fiberglass or marine painted prefabricated unit does not
					 require plasticizing. Rooms shall be configured as per paragraph (2) of this
					 subdivision. All prefabricated or trailer decontamination units shall be kept
					 in good condition, and shall be completely decontaminated after final cleaning
					 and immediately prior to clearance air sampling. Upon receiving satisfactory
					 clearance air results, the prefabricated units shall be sealed then separated
					 from the regulated abatement work area and removed from the site.
(8) Clean room. The clean room shall be sized
					 to accommodate a full workshift of asbestos abatement contractor personnel, as
					 well as the air sampling technician and the project monitor. The clean room
					 shall be a minimum of six feet in height. A minimum of 32 square feet of floor
					 space shall be provided for every six full shift abatement workers, calculated
					 on the basis of the largest work shift. If the largest work shift consists of
					 three or less full shift abatement workers, the minimum clean room size
					 requirement is reduced to 24 square feet of floor space. Benches, lockers and
					 hooks shall be provided for street clothes. Shelves for storing respirators
					 shall be provided. Clean clothing, replacement filters for respirators, towels
					 and other necessary items shall be provided. The clean room shall not be used
					 for storage of tools, equipment or materials. It shall not be used for office
					 space. A lockable door shall be provided to permit access to the clean room
					 from outside the regulated abatement work area or enclosure and shall be used
					 to secure the regulated abatement work area and decontamination enclosure
					 during non-work hours.
(9) Shower
					 room. The shower room shall contain one shower per every six full shift
					 abatement workers, calculated on the basis of the largest work shift. Multiple
					 showers shall be simultaneously accessible (installed in parallel) to certified
					 personnel. Each showerhead 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. Uncontaminated soap, shampoo and towels 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. Submersible pumps
					 shall be installed, maintained and utilized in accordance with pertinent OSHA
					 regulations and manufacturer's recommendations. A multi-stage filtering system
					 containing a series of several filters with progressively smaller pore sizes
					 shall be used to avoid rapid clogging of the filtering system by larger
					 particles. Filtered wastewater shall be discharged in accordance with
					 applicable codes. Contaminated filters shall be disposed of as
					 asbestos-contaminated waste.
(10)
					 Equipment room. The equipment room shall be used for the storage of
					 decontaminated equipment and tools. A one-day supply of replacement filters for
					 HEPA-vacuums and negative pressure ventilation equipment in sealed containers,
					 extra tools, containers of surfactant and other materials and equipment that
					 may be required during the abatement project may also be stored here. A
					 container lined with a labeled, at least six mil plastic bag for collection of
					 clothing shall be located in this room. Contaminated footwear and work clothes
					 shall be stored in this area.
(11)
					 Airlocks. Airlock construction shall consist of two curtained doorways with
					 three alternating six mil fire-retardant polyethylene curtains per doorway,
					 separated by a distance of at least three feet, such that one passes through
					 one doorway into the airlock, allowing the doorway sheeting to overlap and
					 close off the opening before proceeding through the next doorway. Minimum
					 airlock size shall be three feet wide, by three feet long, by six feet in
					 height.
