Before the protective sheeting is taken up, what must be done with paint chips and debris?

  1. Sweep them into a corner for later
  2. Collect them and seal them in a heavy-duty bag
  3. Blow them outside the house with compressed air
  4. Leave them for the final vacuuming

B. Collect them and seal them in a heavy-duty bag

The first cleaning step is to collect all paint chips and debris and seal them in a heavy-duty bag without spreading them. Compressed air and dry sweeping scatter lead dust.

Reference: 40 CFR 745.85(a)(5)

How are walls in the work area cleaned after an interior renovation?

  1. Dusted with a dry brush, from the floor up
  2. Rinsed with a garden hose
  3. HEPA vacuumed or wiped with a damp cloth, from the ceiling down
  4. Left alone unless paint was removed from them
Show the answer

C. HEPA vacuumed or wiped with a damp cloth, from the ceiling down

Walls are cleaned starting at the ceiling and working down to the floor, by HEPA vacuuming or wiping with a damp cloth. Dry brushing just moves the dust into the air.
