Popcorn Ceiling in an Occupied Apartment
A contractor has a Delaware business license but no asbestos abatement contractor certification. The crew is removing 900 sq ft of popcorn ceiling in an occupied 1970 apartment building. The supervisor has no asbestos supervisor training; two workers have never had a fit test or medical clearance. They hang one layer of 6-mil poly around the room, use a box fan to pull air out a window, and wear half-face elastomeric respirators with P100 filters. They eat lunch inside the containment, bag debris in single 6-mil bags, and write 'trash' on the bags. No air monitoring, no decontamination shower, no HEPA vacuum; they use a shop vac to clean up. The property manager wants the apartment ready in three days.
1. Can the job lawfully proceed? Identify the most serious deficiencies and explain why they matter.
Read the worked answer
No. The job should be stopped until a properly certified contractor and trained crew are in place. The most serious deficiencies are:
- No asbestos abatement contractor certification. A general business license is not an asbestos abatement credential. Delaware requires abatement contractors to hold the appropriate state certification, and supervisors and workers must be trained.
- No supervisor training. The person in charge cannot recognize deficiencies or enforce work practices.
- No fit testing or medical clearance for respirator use. A respirator that does not fit provides no reliable protection, and medical clearance is required before required respirator use.
- No HEPA vacuum and no decontamination. A shop vac can redistribute asbestos dust, and workers can carry contamination out on clothing.
- Box fan instead of HEPA negative air. It may spread fibers rather than control them.
- Eating in the containment violates the regulated-area concept and increases ingestion exposure.
- Single bags labeled 'trash' are inadequate for asbestos waste.
The property manager's three-day deadline does not change these requirements.
2. Describe a minimally compliant containment and work-practice setup for this occupied apartment.
Read the worked answer
A compliant setup should include:
- Critical barriers at openings and a controlled entry; the containment should be constructed to prevent dust migration.
- HEPA negative-air units sized for the space, with the exhaust arranged so air flows from clean to dirty areas.
- A decontamination system appropriate to the job, including a clean room, shower or equivalent, and equipment room, or a justified small-scale alternative.
- Wet methods for ceiling removal, with amended water and no dry scraping.
- HEPA vacuuming for cleanup, not a shop vac.
- Respirator program with fit testing, medical clearance, training, and appropriate cartridges.
- No eating, drinking, or smoking in the regulated area.
- Waste handling: wet, double-bag, label with the required warnings, and seal.
- Notification and air monitoring/clearance as required before occupants return.
The containment should be inspected before work begins and the occupant should be relocated if the work cannot be isolated safely.
3. How should the contractor respond to the property manager's three-day deadline?
Read the worked answer
The contractor should not let the deadline drive unsafe or unlawful work. The correct response is to explain that the job cannot be completed in three days as currently staffed and equipped, and to offer options:
- Stop work immediately if removal has begun.
- Relocate the occupant or delay reoccupancy until containment, removal, cleanup, and clearance are complete.
- Bring in a certified abatement contractor with trained workers and proper equipment.
- Revise the schedule based on notification lead time, containment setup, removal, and clearance. Three days may be unrealistic even for a compliant job once notification and setup are included.
If the property manager pressures the crew to continue, the contractor should document the refusal and the reason. Safety and licensing requirements are not negotiable schedule variables.
