Alabama Administrative Code › Title 420 - ALABAMA STATE BOARD OF HEALTH › Chapter 420-3-29 - RENOVATION CONTRACTOR CERTIFICATION › Section 420-3-29-.10 - Work Practice Standards For Conducting Renovation

Current through Register Vol. 42, No. 9, June 28, 2024
(1)
Standards for renovation
			 activities
. Renovations must be performed by certified firms using
			 accredited renovators as directed in Rule
			 420-3-29-.05. The
			 responsibilities of certified firms are set forth in Rule
			 420-3-29-.05 and the
			 responsibilities of accredited renovators are set forth in Rule
			 420-3-29-.11.
(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 remain readable until the renovation and the
			 post-renovation cleaning verification has been completed. If warning signs have
			 been posted in accordance with
			 24 CFR §
										35.1345(b)(2) or
			 29 CFR
			 §
										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.
1.
Interior renovations
. The firm must:
(i) 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.
(ii) Close and
			 cover all openings, including duct openings, in the work area with taped-down
			 plastic sheeting or other impermeable material.
(iii) 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.
(iv) Cover the floor surface, including
			 installed carpet, with taped-down plastic sheeting or other impermeable
			 material in the work area 6 feet beyond the perimeter of surfaces undergoing
			 renovation or a sufficient distance to contain the dust, whichever is
			 greater.
(v) 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.
2.
Exterior renovations
. The firm must:
(i) Close all doors and windows within 20
			 feet of the renovation. On multi-story buildings, close all doors and windows
			 within 20 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.
(ii) 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.
(iii) Cover the
			 ground with plastic sheeting or other disposable impermeable material extending
			 10 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 10 feet of such ground covering.
(iv) In certain situations, the renovation
			 firm must take extra precautions in containing the work area to ensure that
			 dust and debris from the renovation does not contaminate other buildings or
			 other areas of the property or migrate to adjacent properties.
(c) Prohibited and
			 restricted practices
.
The work practices listed below shall be
			 prohibited or restricted during a renovation:
1. Open-flame burning or torching of
			 lead-based paint.
2. The use of
			 machines that remove lead-based paint through high speed operation such as
			 sanding, grinding, power planning, needle gun, abrasive blasting, or
			 sandblasting, unless such machines are used with HEPA exhaust
			 control.
3. Operating a heat gun on
			 lead-based paint, unless temperatures remain below 1100 degrees
			 Fahrenheit.
(d) Waste
			 from renovations must be handled as follows:
1. Waste from renovation activities must be
			 contained to prevent release 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.
2. 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.
3. 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.
1.
Interior and exterior
			 renovations
. The firm must:
(i)
			 Collect all paint chips and debris and, without dispersing any of it, seal this
			 material in a heavy-duty bag.
(ii)
			 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 non-contaminated rooms must
			 remain in place until after the cleaning and removal of other sheeting. Dispose
			 of the sheeting as waste.
2.
Additional cleaning for
			 interior renovations
.
The firm must clean all objects and surfaces in the work area
				and within 2 feet of the work area in the following manner, cleaning from
				higher to lower:
(i) 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.
(ii) 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.
(iii) 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 2-bucket mopping method, or using a wet mopping system.
