Lead Safety in Demolition and Renovation
Disturbing lead paint or coatings during demolition or renovation triggers exposure assessment, dust controls, worker hygiene and waste handling sized to the task.
Four lead thresholds to recognize
Quick-reference overview. The actual project scope, site conditions, qualified evaluations and applicable requirements control.
Tap a number
Poly on the floor and walls, sized to the work, keeps lead dust inside. Surfaces are misted before anything is disturbed.
A sealed doorway with flaps. People, tools and debris leave only through it.
HEPA vacuums and wet wiping only. No dry sweeping and no compressed air.
Work clothes come off and hands and face get washed before anyone leaves. No food, drink or tobacco in the work area.
Debris is bagged, sealed and labeled, then tested and manifested for disposal.

Fun facts
Three details worth remembering
- The limits dropped sharply in 2025
The Cal/OSHA action level fell from 30 to 2 µg/m³ and the permissible exposure limit from 50 to 10, so tasks below the old limits may need controls now.
- Trigger tasks set the starting protection
Until monitoring shows otherwise, listed tasks carry presumed exposure levels and the protection that goes with them.
- Painted steel counts
Torch-cutting coated steel during demolition is one of the highest lead-exposure tasks on a job, not just paint scraping.

Test before you disturb
Get a lead inspection, XRF readings or paint chip results before pricing and planning, and treat older coatings as lead-containing until tested. Work in residential and public buildings is performed by CDPH-certified personnel, and pre-1978 housing and child-occupied facilities follow EPA lead-safe renovation practices.
Assess exposure and protect workers
Make an initial exposure assessment and provide interim protection based on the trigger task until air monitoring results are in. Above the action level, monitoring, training and medical surveillance apply; above the permissible exposure limit, a written compliance program, respirators and hygiene facilities are added.
Control the dust
Set up containment sized to the work, mist surfaces before disturbance and collect debris with HEPA vacuums, with no dry sweeping or compressed air. Provide wash facilities and a change area, and keep food, drink and tobacco out of the work area.
Clean, clear and dispose
HEPA-vacuum and wet-wipe before containment comes down, and run clearance testing where the owner or regulations require it. Characterize the waste stream, then package, label and manifest it for disposal.
