Asbestos Clearance Testing

Asbestos Clearance Sampling
Certified Testing. In-House Analysis. Fast, Compliant Results.

PCM air sampling pump in use inside containment Final Clearance You Can Trust—Start to Finish Clearance sampling is a legally required step after asbestos abatement to confirm the area is safe for re-entry. At Safe Home Environmental, we handle the entire process—from certified sample collection to accredited lab analysis—in one streamlined service.

We are proud to be a Montana DEQ-licensed Asbestos Contractor/Supervisor and a certified asbestos lab for Phase Contrast Microscopy (PCM) using the NIOSH 7400 Method. This means we don’t just collect your samples—we analyze them in our own lab, giving you faster results and tighter quality control.

When Clearance Sampling Is Required, Asbestos clearance testing is essential after:

Asbestos abatement or removal.
Fire, flood, or disaster restoration involving suspect materials
Pre-demolition clearance (especially commercial/regulated buildings)
Remodeling or repair in homes built before 1985
Complying with DEQ, OSHA, or EPA regulations

Our Clearance Testing & Lab Process Setup & Calibration

We begin by performing a visual inspection to ensure the abatement was thorough. Then, we deploy calibrated PCM air pumps (typically at 10–15 LPM) and sample using 25mm 0.8µm MCE filters per NIOSH guidelines.

Air Collection

We collect a minimum of 1,200 liters of air per sample. Five samples are collected in the containment area. A Control blank is also collected to verify lab accuracy.

In-House PCM Analysis

Samples are analyzed in our on-site certified asbestos lab, using Phase Contrast Microscopy (PCM) following the NIOSH 7400 Method, Option A. This ensures compliance with OSHA and EPA re-occupancy criteria.

Clearance Report

You’ll receive a comprehensive report documenting fiber concentrations. A result of < 0.01 f/cc is required for re-occupancy. Reports include sample logs, chain-of-custody, calibration data, and lab analysis sheets.

Why It Matters:

Unlike third-party labs that introduce delays or risk miscommunication, we do it all in-house, meaning:
