Reparación intrafetal

A. Notification: Notify the Owner 10 days prior to the start of any paint removal work. B. Lead Control Area Requirements.

1. Establish a lead control area by completely enclosing with temporary plastic ceilings, walls, floors (as applicable) the area or structure where lead-containing paint removal operations will be performed.

2. Contain removal operations by the use of a negative pressure full containment system with at least one change room and with HEPA filtered exhaust.

C. Protection of Existing Work to Remain: Perform paint removal work without damage or

contamination of adjacent areas. Where existing work is damaged or contaminated, restore work to its original condition.

D. Boundary Requirements: Provide physical boundaries around the lead control area by roping off the area [designated on the drawings] or providing curtains, portable partitions or other enclosures to ensure that airborne concentrations of lead will not reach 30 micrograms per cubic meter of air outside of the lead control area.

E. Heating, Ventilating and Air Conditioning (HVAC) Systems: Shut down, lock out, and isolate HVAC systems that supply, exhaust, or pass through the lead control areas. Seal intake and exhaust vents in the lead control area with 6-mil plastic sheet and tape. Seal seams in HVAC components that pass through the lead control area.

F. Mechanical Ventilation System:

1. Use adequate ventilation to control personnel exposure to lead in accordance with 29 CFR 1926.57.

BID SET – 15-33 LEAD-BASED PAINT REMOVAL AND DISPOSAL 2. To the extent feasible, use fixed local exhaust ventilation connected to HEPA filters or other

collection systems, approved by the industrial hygienist. Local exhaust ventilation systems shall be designed, constructed, installed, and maintained in accordance with ANSI Z9.2. 3. If air from exhaust ventilation is recirculated into the work place, the system shall have a high

efficiency filter with reliable back-up filter and controls to monitor the concentration of lead in the return air and to bypass the recirculation system automatically if it fails. Air may be recirculated only where exhaust to the outside is not feasible.

G. Personnel Protection: Personnel shall wear and use protective clothing and equipment as

specified herein. Eating, smoking, or drinking is not permitted in the lead control area. No one will be permitted in the lead control area unless they have been given appropriate training and protective equipment.

H. Warning Signs: Provide warning signs at approaches to lead control areas. Locate signs at such a distance that personnel may read the sign and take the necessary precautions before entering the area. Signs shall comply with the requirements of 29 CFR 1926.62.

3.2 GENERAL WORK PROCEDURES

A. It should be assumed that all painted surfaces contain concentrations of lead in the paint coating. All on-site Contractor personnel involved in work tasks that may disturb LBP shall have received training. See survey reports for exceptions.

B. Perform removal of lead-containing paint in accordance with approved lead-containing paint removal plan. Use procedures and equipment required to limit occupational and environmental exposure to lead when lead- containing paint is removed in accordance with 29 CFR 1926.62, except as specified herein. Dispose of removed paint chips and associated waste in compliance with Environmental Protection Agency (EPA), federal, state, and local requirements.

B. Monitoring: Monitoring of airborne concentrations of lead shall be in accordance with 29 CFR 1910.1025.

C. Clearance testing of the worksite shall be performed at the conclusion of repair, demolition or interim controls.

3.3 LEAD-CONTAINING PAINT REMOVAL

A. Indoor Lead Paint Removal: Select paint removal processes to minimize contamination of work areas with lead-contaminated dust or other lead-contaminated debris/waste. This paint removal process should be described in the lead-containing paint removal plan. Perform manual sanding and scraping to the maximum extent feasible.

B. Mechanical Paint Removal and Blast Cleaning: Perform mechanical paint removal and blast cleaning in lead control areas using negative pressure full containments with HEPA filtered exhaust. Collect paint residue and spent grit (used abrasive) from blasting operations for disposal in accordance with EPA, state and local requirements.

C. Outside Lead Paint Removal: Select removal processes to minimize contamination of work areas with lead-contaminated dust or other lead-contaminated debris/waste. This paint removal process

BID SET – 15-33 LEAD-BASED PAINT REMOVAL AND DISPOSAL should be described in the lead-containing paint removal plan. Perform manual sanding and scraping to the maximum extent feasible.

3.4 SURFACE PREPARATIONS

A. Provide surface preparations for painting in accordance with Section 0999000, Painting and Coating.

B. All work shall be conducted by a certified renovators and firms.

3.5 WALL DEMOLITIONS

A. There is a high potential for exposure to lead and lead dust during demolition work. The Contractor is responsible for monitoring work activities and determining when work involves hazardous materials and conditions that require conformance with specified regulatory

requirements. The health and safety plan required is to address the pertinent health and safety issues associated with potential exposure to lead. A site specific health and safety plan for lead is required for each work assigned under this contract involving handling, exposure to or demolition and dismantling of LBP materials.

B. All work shall be conducted by a certified firms, certified lead abatement workers and supervisors or HAZWOPER trained personnel.

3.6 CLEANUP AND DISPOSAL

A. Cleanup: Maintain surfaces of the lead control area free of accumulations of paint chips and dust. Restrict the spread of dust and debris; keep waste from being distributed over the work area. Do not dry sweep or use compressed air to clean up the area. At the end of each shift and when the paint removal operation has been completed, clean the area of visible lead paint contamination by vacuuming with a HEPA filtered vacuum cleaner and wet mopping the area.

B. Disposal:

1. All lead-coated removed debris shall be handled, stored and disposed of as to meet applicable Federal, State and Local requirements.

2. Collect lead-contaminated waste, scrap, debris, bags, containers, equipment, and lead- contaminated clothing, which may produce airborne concentrations of lead particles. Dispose of lead-contaminated waste material at an EPA or state approved hazardous waste treatment, storage, or disposal facility.

3. It is assumed that all painted debris is classified as Hazardous Waste under the Washington State Department of Ecology Regulations. If the Contractor chooses to disprove the

assumption that the demolition debris is a Hazardous Waste, the Contractor shall collect representative samples of debris for TCLP analysis. The Contractor shall test debris in accordance with WAC 173-303 to determine whether the waste designates as “Hazardous Waste” or a “Dangerous Waste”.
