Limiting the Lead Dust Generated in the Lead Contaminated Worksite

Limiting the amount of dust generated on a daily basis is critical to maintaining a healthy worksite as well as facilitating a fast clean-up when the project finalizes. These quick tips performed on a daily basis add only a few minutes to each workday, but save hours of clean-up on the backend.

When working on surfaces containing lead, mist them with water prior to sanding, scraping, cutting or drilling. This simple trick will cut down lead dust dramtically.

Prior to pulling apart components, score the joint with a utility knife and pry apart rather than pounding or breaking. This will minimize the amount of lead paint chips generated at the site.

When dealing with windows sills and other nonporous surfaces, you can use chemical strippers without methylene chloride to remove the contaminated paint without generating dust.

Wipe down the work space regularly with wet wipes and disposable swiffer wetjet pads to reduce the dust buildup. Place all debris in a heavy duty trash bag daily. Trash bags should be sealed with duct tape and removed to a secure dumpster or storage facility.

HEPA vacuum the area on a daily basis, and clean all tools before removing them from the worksite.

Equipment You will Need

•Water Spray Bottle
•Utility Knife
•Dry/wet Sandpaper
•Chemical strippers without Methylene Chloride
•Power tools with dust muzzle attachments for HEPA vacuum cleaners
•HEPA vacuum cleaner
•Low-temperature heat gun
•Dry Wipes, Wet Wipes and Swiffer Wipes
•Heavy-duty plastic bags
•Duct Tape to seal the trash bags

Caution: Certain procedures are prohibited by the RRP Rules in a lead safe work space. Use of power tools to sand, scrape, grind, plane or drill without a HEPA vacuum shroud attachment is strictly prohibited. Compressed air or sand blasters may not be used to remove lead from any of the surfaces. As with all renovation activities common sense should prevail - if inhaling lead dust is highly dangerous to your health, heating it to a vapor will be extremely hazardous to your health. Therefore, you may use a low-temperature heat gun, but heat guns used in excess of 1100 degrees are prohibited, as are open-flame burning torches.
