Asbestos is a hazardous material that was widely used in construction throughout the 20th century. While undisturbed asbestos poses minimal risk, it becomes dangerous when disturbed, releasing microscopic fibres into the air. And, there is often a high risk of asbestos becoming disturbed due to the age of most contaminated building materials. When its fibres enter the air,  inhalation can lead to severe health conditions, including asbestosis, mesothelioma, and lung cancer. Because of these risks, it is critical that asbestos removal is handled with the utmost care, from air quality testing to asbestos removal in Toronto. At Inch By Inch Inspections, we offer safe, comprehensive asbestos removal services, including air quality testing in Toronto.

Here are some of the reasons air quality testing matters when planning asbestos removal. 

Why Air Quality Testing Matters

Without proper monitoring, there’s no definitive way to determine how many fibres are present or whether abatement efforts have entirely removed the contamination. Air quality testing in Toronto with Inch By Inch Inspections can help you measure the concentration of fibres, empowering technicians to determine whether the property is safe to occupy or the approach required for safe asbestos removal. This not only protects the health of occupants but can also shield property owners and contractors from liability.

Benefits of Air Quality Testing During Asbestos Removal

When the potential for asbestos on your property comes up, air quality testing can help you streamline the process. Working with Inch By Inch Inspections, you can count on our team for designated substance survey reports, air quality testing, and asbestos removal to support efficient, compliant, and safe abatement. 

  • Risk Assessment: Before asbestos removal begins, air quality testing helps establish a baseline. This determines if airborne fibres are already present and informs the safety protocols needed for abatement.
  • Containment Validation: During removal, testing ensures that containment measures (such as sealed work areas and HEPA filtration systems) are functioning correctly and fibres are not escaping into other parts of the building.
  • Post-Removal Clearance: After the abatement is completed, final air tests verify that asbestos fibres are no longer present at hazardous levels. Only once these results meet regulatory standards can a space be deemed safe for reentry.
  • Regulatory Compliance: Air testing helps meet provincial and federal safety regulations. In Ontario, for instance, asbestos abatement must follow strict Ministry of Labour guidelines, including clearance air testing for certain classes of work.
  • Peace of Mind: For homeowners, tenants, and business owners, testing offers peace of mind, knowing that their environment is truly safe after asbestos removal.

What Happens During Air Quality Testing?

Air quality testing is carried out by licensed professionals using specialized equipment. During the process, air samples are collected and then sent to labs for analysis, where they can determine the fibre count per cubic centimetre of air. After, a report is generated to explain asbestos levels compared to acceptable thresholds.
