What Is Asbestos Air Monitoring?

Asbestos air monitoring involves collecting air samples during or after asbestos-related work to determine whether airborne asbestos fibres are present and whether the work area meets applicable safety requirements.

Asbestos can become a health concern when materials containing it are disturbed during renovation, demolition, repair, or removal. Health Canada identifies exposure to airborne asbestos fibres as a cause of serious diseases including lung cancer, asbestosis, and mesothelioma.

Air monitoring provides an objective way to check conditions during asbestos work rather than relying only on visual inspection.

When Is Air Monitoring Needed?

The type and frequency of monitoring depend on the work being performed and the level of asbestos exposure risk.

For high-risk asbestos work, WorkSafeBC requires airborne asbestos monitoring in specified areas, including areas outside the containment and the clean room. Clearance air sampling is also required before containment is dismantled, once asbestos waste and contamination have been cleaned up or otherwise controlled.

Air monitoring may therefore be part of:

Asbestos removal and abatement projects
Renovation or demolition work involving asbestos-containing materials
High-risk asbestos work
Containment monitoring
Final clearance testing

How Does Asbestos Air Testing Work?

A qualified technician uses calibrated air-sampling equipment to collect samples from selected areas of the worksite. The samples are then submitted for laboratory analysis using an accepted analytical method.

A typical process includes:

Site Assessment
The testing professional reviews the work area and determines an appropriate sampling strategy.
Air Sampling
Air samples are collected from locations relevant to the asbestos work and containment setup.
Laboratory Analysis
Collected samples are analyzed to determine whether asbestos fibres are present and, where applicable, their concentration.
Results and Reporting
The laboratory results are reviewed and documented for the project.
Clearance, When Required
For applicable high-risk work, clearance air sampling is completed after cleanup and before containment is dismantled. WorkSafeBC specifies that airborne asbestos fibre levels must not exceed 0.02 f/mL for clearance in these circumstances.

Air Monitoring vs. Clearance Testing

These terms are sometimes used interchangeably, but they are not exactly the same.

Air Monitoring	Clearance Testing
May take place during asbestos work	Takes place after removal and cleanup
Helps monitor conditions and potential exposure	Determines whether the containment can be dismantled
Can involve different sampling locations depending on the project	Performed in previously contaminated areas
Frequency depends on the work and applicable requirements	Required before dismantling containment for applicable high-risk work

WorkSafeBC requires employers performing high-risk asbestos work to conduct monitoring in specified areas and requires clearance air sampling before dismantling the containment.

Asbestos and Renovation Work in Mission

If you are renovating or demolishing an older property in Mission, asbestos should be considered before work begins.

WorkSafeBC recommends having a hazardous materials survey conducted before renovation or demolition work that could disturb hazardous materials. Homes built before 1990 are particularly important to assess, although asbestos can also be present in buildings constructed later.

The City of Mission’s demolition submission checklist also requires a Hazardous Materials Assessment and, where hazardous materials are identified, a WorkSafe Notice of Permit as part of the demolition submission process.

Potential asbestos-containing materials can include:

Textured or popcorn ceilings
Drywall joint compound
Vinyl flooring and related materials
Pipe and mechanical insulation
Cement-based products
Certain insulation materials
Roofing and exterior building products

The presence of asbestos cannot be confirmed reliably just by looking at a material. Appropriate assessment and testing should be completed before materials are disturbed.

What Happens If Clearance Testing Does Not Pass?

If clearance results do not meet the applicable requirement, the containment should not simply be removed.

The affected area may need additional cleaning and corrective work before another clearance sample is collected. For high-risk work in B.C., WorkSafeBC requires the airborne asbestos fibre level to be no more than 0.02 f/mL before the containment can be dismantled.

How Much Does Asbestos Air Monitoring Cost in Mission?

The cost depends on the project rather than being a fixed amount. Factors can include:

Number of air samples required
Size and layout of the work area
Type of asbestos work
Number of sampling locations
Laboratory analysis
Whether clearance testing is required
Project timing and reporting requirements

For an accurate price, it is better to assess the specific project before quoting a testing cost.

Frequently Asked Questions

What is asbestos air monitoring?

It is the process of collecting and analyzing air samples to determine whether airborne asbestos fibres are present and to help assess conditions during asbestos-related work.

Is asbestos dangerous?

Yes. Inhaling asbestos fibres can cause serious diseases including lung cancer, asbestosis, and mesothelioma. Risk is associated with exposure to airborne fibres, particularly when asbestos-containing materials are disturbed.

Do older homes in Mission need asbestos testing before renovation?

If renovation or demolition could disturb asbestos-containing materials, a hazardous materials assessment should be completed before work begins. WorkSafeBC specifically advises testing homes before renovation or demolition, particularly homes built before 1990.

What is asbestos clearance testing?

Clearance testing is air sampling performed after asbestos removal and cleanup to determine whether the area meets the applicable clearance requirement before containment is dismantled.

What is the WorkSafeBC clearance limit?

For applicable high-risk asbestos work, WorkSafeBC requires airborne asbestos fibre levels to be no more than 0.02 f/mL before containment is dismantled.

Can I test asbestos air myself?

Professional asbestos air monitoring requires appropriate sampling equipment, procedures, and laboratory analysis. For renovation or demolition projects involving potential asbestos exposure, qualified professionals should be used.

Can I stay in my home during asbestos removal?

This depends on the project, the location of the work, the containment setup, and the controls being used. Follow the instructions of the asbestos abatement and safety professionals managing the project rather than assuming other parts of the home are safe to occupy.

What should I do before renovating an older home?

Before disturbing walls, ceilings, flooring, insulation, or other potentially hazardous materials, arrange for a qualified hazardous materials assessment. If asbestos is identified, the required controls, removal procedures, and monitoring should be established before renovation begins.
