Hazardous Materials Surveys

Renovation or demolition projects in residential, commercial, or industrial settings can be risky if hazardous materials are present. Identifying these materials before beginning any work is crucial for the safety of building occupants and the protection of workers and the environment. Hazardous materials surveys ensure compliance with local and provincial safety regulations, minimize exposure to harmful substances, and create a clear, safe removal and management plan.

What is a Hazardous Materials Survey?

A hazardous materials survey is a comprehensive inspection and analysis designed to detect the presence of dangerous substances within a building or site. These surveys are required before any renovation or demolition project occurs. Hazardous materials include asbestos, lead, mould, mercury, polychlorinated biphenyls (PCBs), and other harmful substances commonly found in older buildings or specific construction materials. During the survey, certified professionals collect samples from materials suspected of containing asbestos and lead. These samples are then sent to hygiene laboratories for analysis, ensuring that any hazardous materials are accurately identified.

Why is it Important?

When hazardous materials are disturbed without proper precautions in place, workers can be exposed, creating significant health risks. For instance, asbestos fibres, when inhaled, can cause severe lung conditions, including asbestosis, mesothelioma, and lung cancer. Similarly, lead exposure can result in developmental issues, particularly in children, and prolonged exposure to other hazardous substances like mercury and PCBs can have lasting adverse effects on human health.

Conducting a hazardous materials survey before starting any work is critical for:

Health and Safety: Ensuring the well-being of workers, occupants, and the surrounding community by preventing exposure to dangerous substances.
Legal Compliance: Many jurisdictions have strict regulations mandating hazardous materials surveys before renovation or demolition work can proceed. Failure to comply can result in fines, legal liabilities, or work stoppages.
Environmental Protection: Properly identifying and managing hazardous materials helps prevent contamination of the environment, particularly through improper disposal.
Project Planning: Early identification of hazardous materials allows construction teams to plan for their safe removal and disposal, minimizing project delays and ensuring a smooth workflow.

Common Hazardous Materials

Here are some of the most commonly identified hazardous materials during surveys:

Asbestos: Widely used in construction materials until the late 20th century, asbestos can be found in insulation, roofing materials, drywall, vinyl flooring, and more. Disturbing asbestos-containing materials releases microscopic fibres that can be inhaled, leading to serious lung diseases.
Lead: Often found in old paint, plumbing systems, and pipes, lead exposure can cause neurological damage, particularly in children. Renovations that disturb lead-containing materials can create dust and debris that pose a significant health risk.
Mould: Mould can grow in damp areas of buildings and cause respiratory problems, especially for individuals with preexisting health conditions. Mould is often found during renovations in basements, attics, or areas affected by water damage.
Mercury: Frequently used in older lighting systems, thermostats, fluorescent light tubes and bulbs, electrical switches, and some medical devices, mercury exposure can cause severe health issues, including damage to the nervous system.
Polychlorinated Biphenyls (PCBs): Once used in electrical equipment, fluorescent light ballasts, sealants, and paint, PCBs are highly toxic and can have long-term effects on human health and the environment if not handled correctly.

When Should a Hazardous Materials Survey Be Conducted?

Hazardous materials surveys are essential for any renovation, demolition, or construction project, especially in older buildings. They are typically required:

Before Renovations or Demolition: Regulations mandate a hazardous materials survey be conducted before any major renovation or demolition project begins. This is particularly important for buildings constructed before 1990, as these are more likely to contain asbestos, lead, and other hazardous substances.
During Property Transactions: Property owners may require a hazardous materials survey to ensure compliance with environmental and safety regulations when buying or selling older buildings.
After Environmental Incidents: If water damage, fire, or another event may have disturbed hazardous materials in a building, a survey helps assess the level of risk and provides guidance on remediation.
