Lead-Containing Materials Guidelines

15 Lead-Containing Materials equipment. • At break periods or when finished, workers must immediately proceed to assigned cleanup areas to decontaminate. The decontamination areas must be within the barricaded areas and must have polyethylene drop cloths or plastic tarpaulins as a floor. Upon completion of cleanup, discarded PPE will be gathered into 4-6 mil plastic bags or into drums for proper disposal. Waste PPE should be kept separate from paint chips, dusts and debris to allow appropriate disposal. Specific waste characterization and disposal information is outlined in Section VI - Waste Disposal. • When activities are complete, clean up any debris using HEPA vacuums. Working surfaces and the immediate work area should then be wet wiped using disposable towels and a detergent solution. Gather and containerize paint chips, dust, and debris as lead-containing waste. Remove surface polyethylene and final clean the area again using wet methods and HEPA vacuuming. All used towels must be gathered and disposed of as contaminated waste. Surface polyethylene can then be wet wiped, rolled inwards and disposed of as general (non-hazardous) waste. • Waste generated in preparation activities (paint chips, glazing, etc.) should be collected and deposited in an appropriate specific waste container. Characterization and disposal information is outlined in section “Waste Disposal.” • Air monitoring (both area and personal) by EH&S will be necessary until exposure levels can be determined. Exterior Work When performing exterior work follow these guidelines. • Notify the building supervisor and occupants where work involving lead will take place. • Building occupants should be notified to close windows and doors within 25 feet of the work area. • Pre-clean paint chips, dust, and debris from existing surfaces (using HEPA vacuums and wet cleaning methods) before the job begins. Place plastic catch sheeting or tarpaulins to collect debris on the ground, floor or platform directly below the work area, and at least 6 feet out in all directions from the working surfaces. When working on elevated surfaces, an additional 6 feet of catch sheeting is required per floor above the first to a maximum of 25 feet. Individual catch sheets or tarpaulins should be overlapped a minimum of 18 inches and secured to each other. Prepping should not take place on windy days. Catch
