We perform a visual inspection and clearance air testing (e.g., PCM/TEM as applicable) against regulatory criteria. A written clearance report is provided for your records and for contractors/insurers.

Industrial hygiene focuses on identifying, measuring, and controlling workplace exposures (e.g., silica, solvents, welding fumes, noise, heat stress). We provide exposure monitoring, risk assessments, ventilation reviews, and practical control plans and training.

Baseline monitoring is recommended for new processes, chemicals, or tasks, with periodic re-evaluation or when conditions change. Frequency depends on risk, but annual or task-triggered checks help maintain compliance and verify controls.

We conduct a site walkthrough, review HVAC conditions, and collect data such as CO2, CO, temperature, RH, particulates, VOCs, and, if indicated, microbial indicators. Results are compared to recognized guidelines (e.g., ASHRAE/Health Canada) with a clear action plan.

It’s a pre-renovation/demolition survey to identify and locate hazardous building materials like asbestos, lead, PCBs, mercury, ozone-depleting substances, and crystalline silica. Most jurisdictions require this before any work that could disturb these materials.

We identify moisture sources, conduct targeted sampling when warranted, and develop a remediation protocol aligned with IICRC S520. Post-remediation verification confirms dryness, cleanliness, and air quality before re-occupancy.

Many assessments can be done while occupied with minimal disruption. For abatement or remediation, we design containment, negative air, and scheduling strategies (including off-hours) to maintain safety and continuity whenever feasible.
