Section He-P 1608.07 - Preparation of Interior Work Areas

(a) Prior to beginning any lead hazard control activity on the interior of any dwelling, dwelling unit, or child care facility, all interior lead hazard reduction work areas shall be prepared in accordance with Table 8.1 of the HUD "Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing", (2012 Edition) available as noted in Appendix A, to ensure that the work area is isolated and no dust or debris leaves the work area while the work is being performed, in addition to the following requirements:

(1) All sheeting used in containment and barrier systems and sealant materials shall:

a. Be polyethylene sheeting at least 6-mils thick or an equivalent material intended to contain leaded dust and debris;

b. Be secured in place with waterproof tape;

c. Be maintained to prevent the release of lead or lead-contaminated materials from the work areas;

d. Remain in place and intact until clean-up for the preliminary inspection when at least one layer shall remain in place;

e. Be removed before the final clearance inspection;

f. Be stored, managed, and disposed of in accordance with He-P 1608.11;

g. Follow the details outlined in the occupant protection plan written for the lead hazard reduction project in accordance with He-P 1608.05; and

h. Follow the worker protection requirements of He-P 1608.09;

(2) All furniture and related movable and non-movable objects such as refrigerators, stoves, rugs, furniture, window coverings, and food preparation counters in the work area shall be removed from the work area or covered with sheeting used in containment and barrier systems and taped securely at all seams and at all junctures to the floor with waterproof tape;

(3) When heating, ventilation, or air conditioning (HVAC) intake or exhaust vents are located in a lead hazard reduction work area, the HVAC system shall be shut down in the work area and vents sealed with sheeting, used in barrier and containment systems, and waterproof tape;

(4) If a break or tear occurs in any sheeting used in barrier and containment systems to seal the HVAC system:

a. The HVAC system at the site of the break shall be visually inspected by the person conducting the lead hazard reduction work; and

b. Any visible lead contamination shall be cleaned by a cycle of vacuuming with a HEPA vacuum, wet washing with a general all-purpose or lead-specific cleaner, and a repeat HEPA vacuuming;

(5) Floor sheeting shall comply with the following:

a. Sheeting shall be sized to minimize seams;

b. A minimum of 2 layers of 6-mil polyethylene sheeting, or an equivalent material intended to contain leaded dust and debris, and sealant materials shall be maintained to prevent the contamination of flooring with lead or lead-contaminated materials;

c. If a break or tear occurs in the bottom sheet of any sheeting used in a barrier and containment system that is covering carpeting, the carpet shall be cleaned prior to the clearance inspection by:

1. A thorough vacuuming with a HEPA vacuum;

2. Shampoo or steam cleaning using a general all-purpose or lead-specific cleaner; and

3. A second vacuuming with a HEPA vacuum when the carpet is dry; and

d. If abatement is needed on the flooring, work shall be conducted in phases and sheeting shall meet the requirements above and be utilized in such a manner to prevent lead dust contamination from other abatement work on the existing flooring, underlayment, and new flooring;

(6) A mini-containment area may be built by surrounding the work area with temporary walls to allow small areas to be addressed or windows to be replaced;

(7) The area in (6) above shall comply with:

a. The requirements of (1) through (5) above; and

b. The following:

1. The mini-containment area shall be constructed of wood or other rigid framing and 6-mil polyethylene sheeting or an equivalent material in order to define the area with sides, a ceiling and a floor;

2. An air-flap shall be constructed at the entryway to the mini-containment;

3. The mini-containment shall be affixed securely to the wall such that there are no gaps between the mini-containment and the wall;

4. The mini-containment area shall be subject to daily and final cleaning, as well as clearance sampling requirements;

5. Passageways used by workers going to and from the mini-containment area and other areas used for storage of tools or debris shall be covered with 2 layers of 6-mil polyethylene sheeting or an equivalent material;

6. The mini-containment area shall remain in place until final clean up; and

7. Access to the room where any mini-containment area has been constructed shall be restricted in accordance with the HUD "Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing" (2012 Edition), available as noted in Appendix A, until clearances have been achieved.

(b) Prior to removing lead-based substances or beginning any other lead hazard reduction work, warning signs shall be posted in accordance with the following:

(1) Signs shall be posted at all entrances and exits of the dwelling, dwelling unit, or child care facility clearly defining the work area and warning occupants and other persons not involved in the abatement activities to remain outside the work area;

(2) All signs shall be at least 8.5 inches by 11 inches, and include the phrase "Lead Hazard, Keep Out," or similar wording in bold lettering at least 3/4 inches high;

(3) In common areas that are to be abated in dwellings occupied by 2 or more households or a child care facility, the signs shall be posted at all entrances and exits of the dwelling or child care facility and include the phrase, "Caution Lead Hazard, Do Not Remain in Work Area Unless Authorized," or similar wording, in bold lettering at least 3/4 inches high;

(4) Signs shall remain in place and be readable until abatement is completed and clearance achieved; and

(5) Signs shall include a 24 hour contact phone number and name of person responsible for the work area.

(c) In addition to all of the requirements under (a) and (b) above, when dust generating activities are utilized on the work site during the lead exposure hazard reduction project, a worker changing area shall be:

(1) Set up adjacent to the abatement work area; and

(2) Constructed in accordance with Chapter 9 of the HUD "Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing", (2012 Edition), available as noted in Appendix A.
