Compliance Inspection Finds a Missing Regulated Area Boundary
During a site visit to an occupied office building, you observe a abatement crew removing 3,000 sq ft of vinyl asbestos floor tile in a corridor. The work area is marked with caution tape but there is no critical barrier at the corridor opening to the lobby, and the lobby is occupied by tenants. The negative air unit is running. The supervisor says the tile is non-friable and that a critical barrier is only required for friable work. The daily log shows the crew started this morning. The NOI on file lists floor tile removal and was accepted. No air monitoring results are posted.
1. Is the supervisor correct that no critical barrier is required because the tile is non-friable? Explain.
Read the worked answer
No. The requirement turns on whether the work area is a regulated area and whether the removal method can generate fibers, not solely on the original classification of the material. Floor tile removal by mechanical means (chipping, scraping) can create dust and debris; the work area must be contained and the regulated area boundary controlled.
Additionally:
- The lobby is occupied, which raises the stakes - occupants must be protected.
- A critical barrier at the opening prevents fiber migration and unauthorized entry.
Action: stop work in the affected zone until a critical barrier is installed and the boundary is verified. Document the deficiency and the corrective action. The supervisor's blanket statement is not a defensible basis to skip containment.
2. What else in this scenario do you cite, and what is your enforcement path?
Read the worked answer
Deficiencies:
- Missing critical barrier at the lobby opening.
- No posted air monitoring results (if required by the project/rule).
- Occupied space adjacent to regulated area without documented protection.
Path:
- Issue a written notice of deficiency on site; stop work in the affected zone.
- Require corrective action and re-inspection before resuming.
- Verify the NOI scope matches the work (it does).
- If repeated or willful, escalate per the program's enforcement ladder - but first confirm the facts and give the contractor a chance to cure.
Key point: separate the fixable deficiency from any willful violation; document both.
