What to do if You Suspect Asbestos in your Workplace

Asbestos may no longer be used in new construction, but that doesn’t mean it’s disappeared. Many older buildings and industrial sites across Canada still contain asbestos-containing materials (ACMs). If you suspect asbestos in your workplace, it’s important to take immediate, informed action — not just for compliance, but for the health and safety of everyone on site.

As a consultancy specializing in industrial hygiene and hazardous materials, we help businesses safely assess, manage, and respond to potential asbestos exposure risks. Here’s what you should do if you think asbestos may be present in your facility…

1. Don’t Disturb It

The most important first step: do not disturb the suspected material. Asbestos is most dangerous when it’s airborne. Cutting, drilling, removing, or even touching it can release microscopic fibres into the air. These fibres, when inhaled, can lead to serious health issues such as mesothelioma, asbestosis, and lung cancer.

If you’re unsure, leave it alone until a proper assessment can be done.

2. Restrict Access to the Area

If you can isolate the area where the material is located, do so. Restrict foot traffic and clearly mark the space to prevent accidental disturbance. This is especially important in busy construction zones or maintenance areas.

3. Notify the Right People

Immediately inform your safety manager, project supervisor, or building owner. This sets the process in motion for proper assessment and hazard control. In many provinces, this is also a legal requirement under OHS regulations.

4. Contact a Consultant

As certified professionals, we conduct asbestos testing, material sampling, and risk assessments. A licensed consultant can:

  • Visually inspect the material
  • Collect samples for lab testing
  • Advise on appropriate next steps (management, enclosure, or removal)

Hiring a qualified consultancy ensures you stay compliant with federal and provincial asbestos regulations under the Canadian Environmental Protection Act and local OHS codes.

5. Do Not Attempt DIY Testing or Removal

Handling asbestos without the proper training, equipment, and containment procedures puts workers at risk and violates Canadian asbestos handling regulations. Only licensed professionals should test or remove ACMs.

6. Plan for Abatement or Ongoing Management

If asbestos is confirmed, your options typically include:

  • Removal (Abatement): Safely removing the material with appropriate controls.
  • Encapsulation: Sealing the asbestos in place to prevent fibre release.
  • Enclosure: Isolating the material within a protective barrier.
  • Management Plan: If materials are in good condition and unlikely to be disturbed, a management plan can ensure ongoing monitoring.

Your consultant will help you choose the safest and most cost-effective option based on the material’s condition, location, and risk level.

7. Train Workers and Communicate Clearly

If your facility contains asbestos, workers need to be informed. It may be appropriate for them to do Asbestos Awareness Training that covers things like:

  • Recognizing asbestos-containing materials
  • Safe work practices around asbestos
  • Emergency procedures in case of accidental disturbance

Clear signage and communication are key to preventing exposure.

8. Stay Compliant with Regulations

Canadian law requires specific procedures when working around asbestos, including:

  • Pre-renovation or demolition asbestos surveys
  • Hazard reporting and risk assessment
  • Air monitoring during abatement
  • Proper waste handling and disposal

Working with an industrial hygiene consultancy helps you stay on top of these requirements — and protects your business from potential fines or shutdowns.

Final Thoughts: When in Doubt, Get It Checked Out

Suspecting asbestos in the workplace isn’t cause for panic — but it is cause for action. With the right approach and expert support, you can manage the risk responsibly and protect your team.
