Once highly valued in the building industry for its acoustic insulation, thermal properties, and fire resistance, asbestos is now recognized as a serious health hazard. When renovating an older home, it’s essential to take proper precautions to minimize exposure to this carcinogenic material.
This guide offers practical steps to safely manage asbestos risks in Canada. It covers health dangers associated with asbestos, effective removal techniques, Canadian laws and regulations, and the importance of hiring certified professionals for safe handling.
What is asbestos?
Asbestos is a naturally occurring mineral composed of fine, durable fibers with a fibrous or flaky texture. It comes in various colors, including white, gray, blue, and brown. These fibers are microscopic and typically invisible to the naked eye, making asbestos difficult to identify without specialized equipment.
Due to its inconspicuous nature and tendency to blend with other materials, professional asbestos testing is highly recommended to confirm its presence in a building.
The Dangers of Asbestos
Inhaling asbestos fibers poses serious health risks due to their sharp, needle-like structure and durability. Once inhaled, these fibers settle in the lungs, causing inflammation, scarring, and irreversible damage over time. Long-term exposure to asbestos is linked to several debilitating respiratory diseases, including:
- Asbestosis: Chronic scarring of lung tissue, leading to shortness of breath and reduced lung function.
- Lung Cancer: Often fatal, this cancer develops over time from prolonged asbestos exposure.
- Mesothelioma: A rare and aggressive cancer affecting the lining of the lungs or abdomen.
- Pleural Thickening: Thickening and hardening of the lung’s lining, restricting normal breathing.
What makes asbestos particularly dangerous is its long latency period. Symptoms of asbestos-related diseases often take decades to manifest after initial exposure, complicating early diagnosis and treatment.
This dual-layered risk underscores the importance of stringent precautions during renovations involving asbestos.
Best Practices for Asbestos Removal
Effective asbestos removal practices focus on minimizing the release of airborne fibers to ensure safety. Two widely used methods are wet removal and controlled dismantling.
Wet Removal
This method involves saturating asbestos-containing materials with water or a wetting agent before and during removal. The moisture prevents fibers from becoming airborne, significantly reducing the risk of exposure. Wet removal is especially effective for friable materials like asbestos insulation or spray-applied coatings.
Controlled Dismantling
Controlled dismantling involves carefully separating asbestos-containing structures piece by piece to limit fiber release. Unlike demolition methods that generate excessive debris, this approach uses hand tools instead of heavy machinery to minimize disturbance.
Both techniques prioritize safety and compliance, requiring specialized skills and equipment to ensure proper handling and disposal of asbestos materials.
Factors to Consider When Hiring Asbestos Removal Contractors
Given the serious health risks associated with asbestos, it’s crucial to hire qualified and experienced asbestos removal contractors. Here are key factors to consider:
- Licenses and Insurance: Contractors must hold relevant licenses for asbestos removal and carry comprehensive insurance coverage to protect against potential liabilities.
- Expertise and Experience: Ensure the contractor has a proven track record in asbestos removal and is well-versed in regulations and best practices for handling and disposal.
- References and Client Feedback: Request references from previous clients to assess their satisfaction with the contractor’s performance, adherence to safety protocols, and quality of work.
- Worker Training and Certifications: While it is not legally required for all workers to hold asbestos removal certificates, certifications demonstrate that the team has undergone proper training.
By verifying these qualifications, you can ensure that asbestos removal is handled safely and in compliance with legal requirements, minimizing risks for your household and the surrounding environment.
The Canadian Asbestos Laws and Regulations
Canada has implemented comprehensive federal and provincial regulations to manage the use, removal, and disposal of asbestos, prioritizing public health and safety.
Federal Regulations
The Government of Canada has taken significant steps to ban asbestos and asbestos-containing products. These measures include strict controls and enforcement by federal agencies to eliminate asbestos risks nationwide.
Provincial Regulations
Each province enforces its own asbestos-related laws tailored to specific industries or use cases. For instance, provinces like British Columbia, Ontario, and Newfoundland have detailed guidelines addressing asbestos management, removal practices, and worker safety standards.
By adhering to these regulations, property owners and contractors ensure compliance while reducing health risks associated with asbestos exposure.
Ban on Asbestos and Asbestos Products
Canada has taken decisive steps to ban the use of asbestos and asbestos-containing products. Strict restrictions are in place, with only a few exceptions for specific industries.
The country maintains a comprehensive list of prohibited asbestos products, ensuring their elimination from most applications. Any permitted uses are tightly regulated and monitored to minimize risks and protect public health.
Asbestos Removal Process
Professional asbestos removal in Canada follows a structured protocol to ensure safety and compliance with regulations. Here are the key steps involved in the safe removal and disposal of asbestos:
Site Assessment and Sampling
A qualified surveyor inspects the property, collecting samples for laboratory testing to confirm the presence and type of asbestos.
Risk Assessment and Management Plan
Based on the survey results, a detailed risk assessment is conducted, and an asbestos management plan is developed.
Notification to Authorities
Relevant authorities are notified before any licensed asbestos removal work begins.
Site Preparation
The work area is sealed with polythene sheeting and equipped with negative air pressure units to prevent asbestos fibers from escaping.
Personal Protective Equipment (PPE)
Workers wear appropriate PPE, including respiratory protection and disposable coveralls, to safeguard against exposure.
Asbestos Removal
Licensed contractors remove asbestos-containing materials carefully using specialized tools and wet techniques to limit fiber release.
Waste Packaging
The removed asbestos is securely sealed in labeled, heavy-duty polythene bags for safe transport.
Decontamination
Workers and equipment are thoroughly decontaminated in designated areas to prevent fiber spread.
Air Monitoring
Air samples are collected during the removal process to ensure fiber levels remain below the safety limit of 0.1 fibers per cubic centimeter.
Clearance Inspection
Upon completion, an independent analyst performs a visual inspection and air testing to confirm the area is safe for reoccupation.
Waste Transport and Disposal
Licensed carriers transport asbestos waste to authorized landfill sites equipped to handle hazardous materials.
Documentation
Detailed records, including waste consignment notes, are maintained for regulatory compliance and future reference.
How do I know if my house has asbestos?
It’s difficult to detect asbestos visually since its fibers are microscopic and blend seamlessly with other materials. For accurate identification, samples of suspected materials must be tested in a certified laboratory. Professional asbestos testing services are highly recommended to ensure safety and compliance with regulations.
Can I remove asbestos myself in Canada?
Attempting to remove asbestos without proper training and certification is hazardous and illegal in many cases. Handling asbestos-containing materials releases harmful fibers into the air, posing severe health risks.
For these reasons, hiring licensed and experienced asbestos removal professionals is essential for ensuring safety and compliance with Canadian laws.
How much does professional asbestos removal cost?
The cost of asbestos removal varies depending on factors like the size of the area, the type of materials, and the complexity of the process.
