Asbestos Project Monitor
This domain tests independent oversight: verifying that the contractor follows the specifications, documenting conditions, conducting or overseeing air monitoring, performing visual inspections, and recommending clearance only when criteria are met.
Core rules
- The monitor observes work practices, containment, decontamination, waste handling, and worker protection against the project design and regulations.
- Conduct area and personal air monitoring as specified; calibrate pumps before and after sampling and document chain of custody.
- Perform a thorough visual inspection before clearance sampling. No dust, debris, or visible residue should remain.
- Use aggressive clearance sampling where required; for AHERA school projects, clearance is commonly 0.01 f/cc by PCM, with TEM follow-up if needed.
- Issue a final report with daily logs, noncompliance notices, corrective actions, sampling results, and clearance status. Maintain independence from the abatement contractor.
Worked example
After final cleaning, the monitor performs a visual inspection and finds no debris. Aggressive PCM clearance samples return 0.008 f/cc, below the 0.01 f/cc criterion, and the laboratory reports are complete. The monitor recommends clearance but notes that if the result had been 0.01 f/cc or higher, the area would not pass and re-cleaning and resampling would be required. The reasoning separates visual inspection from numerical clearance.
Traps
Do not clear an area before visual inspection. Do not accept sampling without pump calibration and chain-of-custody records. Do not let the contractor direct the monitor's clearance decision. Do not confuse clearance criteria with the OSHA PEL.
Key points
- Monitor independently against specifications
- Calibrate pumps and document chain of custody
- Visual inspection precedes clearance sampling
- AHERA school clearance commonly 0.01 f/cc by PCM
- Final report documents noncompliance, corrective actions, and clearance
