Lead-Containing Materials Guidelines

13 Lead-Containing Materials D. Operations and Maintenance (O&M) Activities for Lead Painted Surfaces In many instances, routine painting and repair jobs will disturb materials that contain lead. Lead-containing paint and window glazing are just two types of materials that may be encountered. Based on historical personal air monitoring results, significant lead exposures may occur when preparing lead-containing surfaces for repaint or repairing lead-painted window glazing. The procedures in this section should be used to conduct a repair or maintenance activity, not to remove lead-containing materials, but to conduct a repair or maintenance activity. As an example, these guidelines would be used when scraping loose paint in preparation for a repainting job, but would not be appropriate where all paint from a surface (loose and intact) would be removed. Employees conducting O&M activities must have completed Lead Awareness Training, and be enrolled in the ISU Respiratory Protection Program . A small amount of care can significantly decrease the potential for exposure to lead during maintenance activities. Work Methods Acceptable The work methods listed below are acceptable for O&M or limited abatement activities by personnel that have had proper training, medical surveillance, and have completed the appropriate work area set-up. • Operations and Maintenance Work Methods ¤ ¤ Manual scrapers and wire brushes ¤ ¤ Limited manual sanding (preferably wet sanding) with accompanied ventilation (e.g. HEPA vacuum) • Abatement Removal Methods ¤ ¤ Chemical formulations that are approved by EH&S (e.g. methylene chloride-free solutions) ¤ ¤ Heat guns not exceeding 700 degrees Fahrenheit ¤ ¤ Manual scraping with the aid of approved chemical solvents (e.g. methylene chloride-free solutions). ¤ ¤ Paste formulations containing potassium or sodium hydroxide
