Lead Paint – Sunnyvale – Remodeling – Containment – Interior
The containment procedures for the EPA Lead handling practices are a pretty big deal.
Their purpose is to ensure lead dust does not travel outside the work area to other areas of the home.
Since lead is very heavy and lead dust falls to the ground quickly, the containment requirements are less stringent than is needed for asbestos.
Lead dust does not stay airborne, but falls to the ground quickly.
There are different requirements for interior vs exterior, this article describes containment procedures for interior work.
- Everything than can reasonably be moved out of the work area should be.
- Things that can not be reasonably moved must be fully covered, to the point of the plastic sheeting being taped to the floor.
- The plastic sheeting used must be at least 6 mil poly.
- Plastic sheeting must be laid adjacent to the work area extending out a distance of six feet.
- Plastic sheeting must be laid in all high traffic areas (from the building entrance to the work area entrance).
- Disposable tack pads (stick pads that remove dust from the bottom of shoes) should be used immediately outside the containment area.
- Booties should be worn when walking between the containment area and the outside.
- Warning signs must be posted that clearly state “Lead Contaminants”, the OSHA sign is recommended.
- Barrier tape must be installed around the entrance to the containment area.
- The entrance to the containment area must be sealed with two layers of plastic sheeting, one which has an I shaped slit in it to allow people to pass through, and the other which covers the first slit.
- When working in the containment area, workers should wear disposable coveralls.
- When leaving the containment area, workers must “peel off” the disposable coveralls, which are then not re-used.
- Prior to work starting:
- All windows and doors in the containment area must be closed and sealed.
- All HVAC vents and registers must be sealed closed.
- The building HVAC must be turned off.
