Appropriate measures are evaluated below.2. Removal of architectural features from the building and Lead Paint Removal Products controlled removal of lead paint off-site; followed by replacement of the treated features in their original locations. 3.

Young children and pregnant women must stay out of the Lead Paint Removal Products work area until cleanup has been completed. 

Warning signs should be posted outside all entrances and exits to the work area. For any project involving abatement of lead hazards in a residence, or involving removal of more than a very limited amount of lead paint, it is advised that all residents of that home, including pets, Lead Paint Removal Products find other housing. Residents are advised stay out of the building until cleanup has been completed. 

2. Select the safest methods for paint removal. Depending on the materials to be treated and Lead Paint Removal Products the specific circumstances of each building, paint removal procedures that will cause the least damage to the historic materials and yet keep lead residue under control should be chosen. Possible methods, with their advantages and disadvantages, are discussed in detail below.

3. Wear appropriate clothing. Disposable coveralls are recommended to minimize contamination of clothing by lead dust. Disposable shoe covers, to prevent tracking of lead dust outside of the work area, Lead Paint Removal Products are recommended. Neoprene or butyl gloves are indicated when working with methylene-chloride based chemicals.

4. Use required safety equipment. A respirator is recommended. If any lead dust or lead fumes will be produced, Lead Paint Removal Products a respirator with appropriate filters is necessary. 5. Do not smoke, eat, or drink in the work area. Lead dust can easily settle on food or cigarettes.

6. Contain lead dust and debris within the work area. While it may not be possible to control all lead dust, simple measures can greatly reduce the degree of contamination. Plastic sheeting (six-mil polyethylene) sealed at its edges with duct tape, for example, is effective in keeping most lead dust within the immediate work area, Lead Paint Removal Products where it can be picked up with HEPA vacuuming. 

Furniture, rugs, plants, and other items can be removed from the work area prior to beginning treatment. 7. Change clothes, wash hands and face. All persons involved in treatment procedures must take care not to carry dust-contaminated clothing into Lead Paint Removal Products cleaner environments.8. Clean up. Recommended measures for cleanup after lead abatement procedures should consist of High Efficiency Particulate Air (HEPA) vacuuming and washing with tri-sodiumphosphate (TSP) solution. 

Ordinary household vacuum cleaners will not pick up most lead dust. Recommended cleanup specifications are outlined below. A. Interior spaces must be cleaned from ceiling to floor by at least two passes of HEPA vacuuming and Lead Paint Removal Products wet sponge mopping with TSP solution. New batches of TSP must be mixed often to avoid redepositing lead particles. 

After inspection, abated surfaces should be recoated with appropriate finishes before the spaces are returned to use. If substantial amounts of lead dust were generated by the abatement procedures, Lead Paint Removal Products routine washing with TSP solution is indicated for several weeks after the abatement. B. Exterior abatement procedures should be preceded by masking ground surfaces with six mil polyethylene, carefully secured to the building. 

Thorough exterior cleanup should take place at the end of every work day. Lead dust from sanding, residue, and Lead Paint Removal Products paint chips should be collected by HEPA vacuuming. Building surfaces should be washed twice with TSP solution. The top layer of polyethylene masking should be removed at the end of each work day and disposed of properly.

C. Tools, equipment, supplies and materials should not be removed from the site once lead abatement has begun, Lead Paint Removal Products unless they have been decontaminated with HEPA vacuuming and TSP washing. Upon completion of a project, all equipment that cannot be cleaned should be wrapped and sealed in two layers of four mil polyethylene and disposed of properly, along with all sponges, rags, mop heads, and other abatement materials.
