Current through Register Vol. 24-14, July 15, 2024
(1) Standards for renovation activities.
							Renovations must be performed by certified firms using certified renovators as
							directed under WAC
							365-230-370. The responsibilities
							of certified firms are set forth under WAC
							365-230-360 and the
							responsibilities of certified renovators are set forth under WAC
							365-230-380.
(a) Occupant protection. Firms must post
							signs clearly defining the work area and warning occupants and other persons
							not involved in renovation activities to remain outside of the work area. To
							the extent practicable, these signs must be in the primary language of the
							occupants. These signs must be posted before beginning the renovation and must
							remain in place and readable until the renovation and the postrenova-tion
							cleaning verification have been completed. If warning signs have been posted in
							accordance with 24 C.F.R.
							35.1345(b)(2) or
							29 C.F.R.
							1926.62(m), additional signs
							are not required by this section.
(b) Containing the work area. Before
							beginning the renovation, the firm must isolate the work area so that no dust
							or debris leaves the work area while the renovation is being performed. In
							addition, the firm must maintain the integrity of the containment by ensuring
							that any plastic or other impermeable materials are not torn or displaced, and
							taking any other steps necessary to ensure that no dust or debris leaves the
							work area while the renovation is being performed. The firm must also ensure
							that containment is installed in such a manner that it does not interfere with
							occupant and worker egress in an emergency.
(i) Interior renovations. The firm must:
(A) Remove all objects from the work area,
							including furniture, rugs, and window coverings, or cover them with plastic
							sheeting or other impermeable material with all seams and edges taped or
							otherwise sealed.
(B) Close and
							cover all ducts opening in the work area with taped-down plastic sheeting or
							other impermeable material.
(C)
							Close windows and doors in the work area. Doors must be covered with plastic
							sheeting or other impermeable material. Doors used as an entrance to the work
							area must be covered with plastic sheeting or other impermeable material in a
							manner that allows workers to pass through while confining dust and debris to
							the work area.
(D) Cover the floor
							surface, including installed carpet, with taped-down plastic sheeting or other
							impermeable material in the work area six feet beyond the perimeter of surfaces
							undergoing renovation or a sufficient distance to contain the dust, whichever
							is greater. Floor containment measures may stop at the edge of the vertical
							barrier when using a vertical containment system consisting of impermeable
							barriers that extend from the floor to the ceiling and are tightly sealed at
							joints with the floor, ceiling, and walls.
(E) Use precautions to ensure that all
							personnel, tools, and other items, including the exteriors of containers of
							waste, are free of dust and debris before leaving the work area.
(ii) Exterior renovations. The
							firm must:
(A) Close all doors and windows
							within twenty feet of the renovation. On multistory buildings, close all doors
							and windows within twenty feet of the renovation on the same floor as the
							renovation, and close all doors and windows on all floors below that are the
							same horizontal distance from the renovation.
(B) Ensure that doors within the work area
							that will be used while the job is being performed are covered with plastic
							sheeting or other impermeable material in a manner that allows workers to pass
							through while confining dust and debris to the work area.
(C) Cover the ground with plastic sheeting or
							other disposable impermeable material extending ten feet beyond the perimeter
							of surfaces undergoing renovation or a sufficient distance to collect falling
							paint debris, whichever is greater, unless the property line prevents ten feet
							of such ground covering. Ground containment measures may stop at the edge of
							the vertical barrier when using a vertical containment system.
(D) If the renovation will affect surfaces
							within ten feet of the property line, the renovation firm must erect vertical
							containment or equivalent extra precautions in containing the work area to
							ensure that dust and debris from the renovation does not contaminate adjacent
							buildings or migrate to adjacent properties. Vertical containment or equivalent
							extra precautions in containing the work area may also be necessary in other
							situations in order to prevent contamination of other buildings, other areas of
							the property, or adjacent buildings or properties.
(c) Prohibited and restricted
							practices. The work practices listed below are prohibited or restricted during
							a renovation as follows:
(i) Open-flame
							burning or torching of painted surfaces is prohibited.
(ii) The use of machines designed to remove
							paint or other surface coatings through high speed operation such as sanding,
							grinding, power planing, needle gun, abrasive blasting, or sandblasting, is
							prohibited unless such machines have shrouds or containment systems and are
							equipped with a HEPA vacuum attachment to collect dust and debris at the point
							of generation. Machines must be operated so that no visible dust or release of
							air occurs outside the shroud or containment system.
(iii) Operating a heat gun on painted
							surfaces is permitted only at temperatures below 1,100 degrees
							Fahrenheit.
(d) Waste
							from renovations.
(i) Waste from renovation
							activities must be contained to prevent releases of dust and debris before the
							waste is removed from the work area for storage or disposal. If a chute is used
							to remove waste from the work area, it must be covered.
(ii) At the conclusion of each work day and
							at the conclusion of the renovation, waste that has been collected from
							renovation activities must be stored under containment, in an enclosure, or
							behind a barrier that prevents release of dust and debris out of the work area
							and prevents access to dust and debris.
(iii) When the firm transports waste from
							renovation activities, the firm must contain the waste to prevent release of
							dust and debris.
(e)
							Cleaning the work area. After the renovation has been completed, the firm must
							clean the work area until no dust, debris or residue remains.
(i) Interior and exterior renovations. The
							firm must:
(A) Collect all paint chips and
							debris and, without dispersing any of it, seal this material in a heavy-duty
							bag.
(B) Remove the protective
							sheeting. Mist the sheeting before folding it, fold the dirty side inward, and
							either tape shut to seal or seal in heavy-duty bags. Sheeting used to isolate
							contaminated rooms from noncontaminated rooms must remain in place until after
							the cleaning and removal of other sheeting. Dispose of the sheeting as
							waste.
(ii) Additional
							cleaning for interior renovations. The firm must clean all objects and surfaces
							in the work area and within two feet of the work area in the following manner,
							cleaning from higher to lower:
(A) Walls.
							Clean walls starting at the ceiling and working down to the floor by either
							vacuuming with a HEPA vacuum or wiping with a damp cloth.
(B) Remaining surfaces. Thoroughly vacuum all
							remaining surfaces and objects in the work area, including furniture and
							fixtures, with a HEPA vacuum. The HEPA vacuum must be equipped with a beater
							bar when vacuuming carpets and rugs.
(C) Wipe all remaining surfaces and objects
							in the work area, except for carpeted or upholstered surfaces, with a damp
							cloth. Mop uncarpeted floors thoroughly, using a mopping method that keeps the
							wash water separate from the rinse water, such as the two-bucket mopping
							method, or using a wet mopping system.
