PART 2 EXECUTION

2.1 NOT USED

2.2 WORK PROCEDURES

Procedures and equipment required to limit occupational and environmental exposures to lead during LBP removal shall be in accordance with 29 CFR 1926 Section .62, and as specified herein. Paint chips and associated waste shall be disposed of in compliance with Federal, state, and local regulations.

2.2.1 Personnel Protection Procedures

Personnel shall wear and use protective clothing and equipment as specified. Eating, smoking, drinking, chewing tobacco and chewing gum, and applying makeup shall not be permitted in the LBP control area. Personnel of trades not engaged in the abatement and disposal of LBP shall not be exposed at any time to airborne concentrations of lead equal to or in excess of 30 micrograms per cubic meter of air. Electrical service shall be disconnected when wet removal is performed, and temporary electrical service protected by a ground fault circuit interrupter shall be provided.

2.2.2 Safety and Health Procedures

The Project Manager and QAE shall be present on the work site throughout the abatement project to supervise, monitor, and document the project's health and safety provisions. A daily log shall be maintained showing the results of sampling tests throughout the project area. LBP abatement work being conducted within a LBP Control area where an airtight barrier is required shall be stopped if dust wipe concentration levels collected outside the containment area during abatement, equal or exceed the preabatement level or 200 micrograms per square foot, whichever is greater.

The contractor shall provide a copy of the written opinion to the QAE two days prior to each employee's commencement of work.

2.2.5 Engineering Controls and Containment Structures

NOTE: Full containment enclosures with negative air systems should only be used in situations where extreme environmental control is warranted, such as in child‑care centers or other areas where dust exposure to children is a serious concern.

Containment, by their nature, increase the exposure hazards to the workers who work in them. Inhalation and ingestion are the primary routes of exposure to workers. Primary emphasis should be placed on controlling these routes of exposure through good personal hygiene, good housekeeping practices, and sound engineering controls.

2.2.5.1 LBP Control Area

The LBP control area is where LBP abatement work occurs and as such shall be considered contaminated, and shall be isolated to prevent LBP containing dust or debris from passing into adjacent building or open areas. The control area shall be decontaminated at the completion of the LBP abatement and disposal work.

2.2.5.2 Boundary Requirements

Physical boundaries shall be provided around exterior LBP control areas by roping off the area so that concentrations of lead dust outside the LBP control area will not equal or exceed the pre-abatement level or 200 micrograms per square foot, whichever is greater.

The LBP control area shall be separated from other portions of the building and the outside with control barriers. The polyethylene sheeting will have all openings masked and sealed, and shall be erected according to the Department of Housing and Urban Development’s Guidelines for the Evaluation and Control of Lead-Based Paint Hazards, June 1995 edition. Copies of the Guidelines are available from HUD by calling 1-800-245-2691. Polyethylene sheeting shall be mechanically supported, independent of duct tape or spray adhesive.

2.2.5.5 Masking and Sealing

a. Interior LBP control area requirements: Openings shall be sealed where the release of airborne LBP dust is expected. A control area shall be established with the use of curtains, portable partitions, or other systems in order to prevent the escape of dust from the contaminated control area. The control area shall be provided with protective covering of two layers of polyethylene sheeting over floors. Penetrations of the floor, walls, and ceiling shall be sealed with polyethylene sheeting and duct tape. Polyethylene sheeting shall be firmly attached to the structure. Joints shall be sealed with spray adhesive and duct tape. Openings shall be provided for the supply and exhaust of air for the negative air pressure system. Personal monitoring during the work shift shall be in accordance with 29 CFR 1926 Section .62.

b.
