The air around us is filled with various irritants, pollutants and toxins that can have a detrimental effect on your health. If you experience health issues that can’t be easily explained, such as an ongoing cough, nosebleed or respiratory problems, testing the indoor air quality can help identify potential sources of contamination in and around your home. This includes testing for mould, asbestos fibres, and other microscopic particles invisible to the human eye.

Mould and disturbed asbestos fibers are two common pollutants that affect indoor air quality, and they can go overlooked for years before anyone notices.
Due to its cheap and fire-resistant properties, asbestos has been used in construction and manufacturing for a long time. However, once the negative health effects of asbestos were discovered, most countries banned it. Asbestos has been banned from use in Canada since the early 1980s, but its legacy continues to haunt us today.
Disturbed or damaged asbestos fibres easily become airborne and can cause significant health issues if inhaled. Damage to the lungs caused by asbestos fibres can result in physical symptoms such as breathlessness and throat irritation. Prolonged exposure to asbestos can cause respiratory diseases and health issues such as asbestosis, mesothelioma – and lung cancer.
Mould, on the other hand, is a natural part of the environment but can also be very dangerous when growing inside a home or business. Since it needs moisture to survive, mould is often associated with damp buildings or decaying wood. When present indoors, mould can impact indoor air quality by releasing allergens and irritants. Contact with mould can cause respiratory problems like coughing, sneezing, runny nose, sinus congestion, and skin irritation.
It is important to note that mould spores and asbestos fibres are invisible, meaning that you can be exposed to them without even realizing it. With the right air quality testing equipment, it’s possible to detect these harmful particles and make sure that they aren’t present in your home or business.
Call Fisher Engineering Limited if you have any additional questions about our air quality testing services in Toronto, and our team will be happy to assist you.
When it comes to air quality testing services, most home and commercial property owners tend to neglect this. However, is important to be vigilant when carrying out any type of work in an environment that could contain asbestos or mould, whether as a homeowner or a tradesman. Determining the presence of these pollutants and other hazardous materials early through air quality testing can help prevent numerous health issues down the line. For that reason, air quality testing is a necessary step in making sure that the air you breathe isn’t harmful to your health or the environment.

Hazardous Materials (Hazmat)
Chronic exposure to hazardous or toxic substances, such as PCBs, is harmful to human health. In some cases, acute exposure to hazardous and toxic substances can be fatal. Their proper management and disposal are covered in both Federal and Provincial legislations under several Acts and Regulations.
Fisher has the expertise to work with these hazardous materials and provides a full range of services for assessment, sampling, laboratory analysis, and management.
Man-made mineral fibers, ozone-depleting substances (ODS), polychlorinated biphenyls (PCBs), and urea-formaldehyde foam insulation (UFFI). See the list of building materials.
How to deal with Designated Substances
O. Reg. 490/09 provides a consistent approach to dealing with existing requirements and provisions and outlines steps required to control worker exposure to these substances, including inhalation, ingestion, skin absorption, or skin contact.
Each designated substance has an allowable level of exposure based on a time-weighted average (TWA) limit and may also have a short-term exposure limit (STEL) and/or ceiling limit (C) assigned to it.
Designation is reserved for eleven substances that are particularly hazardous, covered under Ontario Regulation 490/09 – Designated Substances, implemented on July 1, 2010.
Formerly, regulations for these substances were passed separately, and each outlined exposure limits where workers were likely to inhale, ingest. and/or absorb the substance.

Asbestos - A Special Case
The Construction Industry
The control of asbestos exposures in the construction industry has evolved into Ontario Regulation 278/05 – Asbestos on Construction Projects and in Buildings and Repair Operations. It is a supplementary regulation.
The regulation includes a definition of asbestos-containing materials (ACM), requirements for additional training, clearance air testing, procedures for determining materials that meet the definition of ACM and for the use of glove bags, and provisions for varying from the measure and procedures set out in the regulation.
In addition to the OHSA and regulations regarding designated substances, the following regulations, guidelines, and standards are also taken into account and referenced:

Designated Substance Survey (DSS)
Based on the regulatory requirements, a survey and report of all Designated Substances, including asbestos, is required:
The survey identifies designated substances present, their locations and concentrations. Activities associated with a designated substances building audit include:
Fisher Engineering Limited has extensive experience conducting building audits for designated substances and other hazardous materials for large municipalities right down to individual homeowners.
