Asbestos Air Monitoring and Clearance
Independent AHERA-compliant project monitoring during abatement, and same-day PCM clearance reports, for schools, government and commercial properties in DC, Maryland and Virginia.
The abatement contractor removes it. We prove the air is clean.
Owners, schools and agencies need someone other than the contractor to watch the work and test the air before the space reopens. That is all we do: monitor during abatement, run clearance, and put the results in writing the same day.
- Personal and area sampling during the work, so the crew and the people outside containment are both covered.
- Same-day phase contrast microscopy (PCM) clearance reports, so the space reopens on schedule.
- TEM analysis when the regulation or the project calls for it.
From pre-assessment to final clearance.
Pre-assessment
Asbestos-containing materials identified and risks assessed before work starts, usually from an asbestos inspection survey.
Air monitoring
Static area samples and personal samples on the crew while abatement is under way.
Sample collection
Bulk material and air filter samples collected under chain of custody for the laboratory.
Lab analysis
PCM for fiber counts, TEM where required, by certified analysts.
Clearance sampling
Post-abatement air testing to confirm the area meets EPA, OSHA and local criteria for re-occupancy.
Same-day report
Results, compliance status and final clearance in writing, the day the samples are run.
Federal, state and local, on one report.
Every project is documented against the rules that apply to the building and the jurisdiction.
- EPA AHERA for schools and the clearance criteria many owners adopt.
- OSHA 29 CFR 1926.1101 for worker exposure during construction.
- NESHAP for demolition and renovation.
- Virginia, Maryland and Washington, DC state and local requirements.
Sensitive buildings, tight schedules.
Schools
AHERA projects timed around breaks and the school calendar.
Government
Federal, state and local facilities with their own documentation rules.
Commercial
Offices, retail and mechanical rooms, often while the rest of the building stays open.
Residential
Homes and multifamily buildings where occupants need a clear answer before moving back in.
