Lead-Positive Corridor in an Occupied Building
You are the lead painter on a four-person crew repainting the common corridor of a 1976 apartment building. The corridor has 180 m² of wall and ceiling, 12 suite doors, and one continuously running make-up air unit. The building is occupied, and one tenant on the floor has a six-month-old infant. A field test on a door casing turns the swab dark, indicating lead; laboratory confirmation is due in 48 hours. The property manager wants work to start Monday to meet a rental inspection and asks you to 'just sand the rough spots and paint over it.' Your company has specified a low-VOC latex. The corridor has no operable windows, only the make-up air unit, and the garbage room is two floors down. The crew includes one apprentice who has not been fit-tested for a respirator. The client has not provided a lead paint report or a pre-renovation notice.
1. What should you do before any sanding, scraping, or demolition begins, and what should you tell the property manager? Include the apprentice in your answer.

Treat the field-positive result as lead until laboratory confirmation. The hazard is not the intact paint film but the dust created when it is disturbed, and the infant is a high-risk occupant.
- Stop all sanding, scraping, heat-gun work, and demolition in the corridor. Do not let the helper reset or start equipment.
- Notify the property manager and building owner in writing: field test positive, lab pending, work paused, and why. Ask for the lead report and pre-renovation notice; if none exists, request a risk assessment by a qualified person.
- Isolate the work area with taped polyethylene and a HEPA air scrubber if available. Shut down or isolate the make-up air unit only after consulting the building engineer, because it can spread dust. Use HEPA vacuuming and wet methods, never dry sweeping.
- Keep the apprentice out of lead-disturbing work until fit-tested and trained; a respirator without fit testing is not protection.
- Discuss relocation or a sealed, dust-tight entry with the tenant. Do not promise the corridor will stay open during dust-generating work.
Tell the manager: 'I cannot sand or paint over this until the lead status and occupant protection are resolved. I can start non-disturbing work outside the corridor, or prepare a containment plan.' Do not accept a verbal instruction to proceed.
2. The manager refuses to relocate the tenant and insists the corridor must be open each evening. Propose a safe work method or schedule that could preserve part of the schedule, and state what you will refuse to do.

If the manager refuses relocation, I would offer phased work only if containment can protect the infant and other tenants.
- Build a sealed enclosure around one work zone at a time, with a zippered entry, negative pressure, HEPA scrubber, and daily visual checks. Keep the corridor route clean and HEPA-vacuum the exit path.
- Remove doors and casings to a controlled off-site area for stripping if they can be replaced the same day; use chemical stripping or wet sanding, not dry sanding or open-flame burning.
- Encapsulation is not a universal fix: it may be considered only on intact, non-friction surfaces and with a compatible product and client approval. Door edges, jambs, and sills are friction or impact surfaces and should not simply be painted over if dust will be generated.
- Schedule dust-generating tasks when the tenant can stay inside a sealed unit, or provide a temporary protected route.
I would refuse dry sanding, uncontrolled demolition, use of a heat gun or torch, running the make-up air during dusty work without engineering advice, and allowing an unfit apprentice into the containment. If containment and occupant protection cannot be achieved, I would stop work and escalate in writing. Safety is not a schedule trade-off.
3. Describe how you will handle waste and what records you will keep.

Waste: collect all paint chips, dust, plastic, and disposable PPE in 6-mil bags, double-bag, label as lead-containing waste, and store away from general refuse. Never use the garbage chute. Use a HEPA vacuum for cleanup and wet-wipe tools. Arrange transport and disposal through the company's licensed waste handler; keep the manifest.
Records: field test result and lab report; photos of containment before, during, and after; daily log of tasks, crew, PPE, fit-test dates, and training; containment inspection and air-scrubber run times; client communications and refusals; waste tracking documents. These records protect the crew, support the change order, and show due diligence.
