What is asbestos? Why is it dangerous?
Asbestos is a naturally occurring silicate found in certain rock formations. It is mined, milled and ground into a powder like product. In that form, it is actually a microscopic fibre. It is flexible and virtually indestructible. It becomes dangerous to humans when inhaled as the body cannot break the fibres down. They embed in the lung tissue and can lead to a number of health problems.
If asbestos is so dangerous to humans, why is it so common in houses and other buildings?
Asbestos doesn't burn, doesn't react with acids, doesn't corrode and is an excellent insulator. As such, it was a tremendous additive to virtually any building material. In the mid 70', it was also discovered to cause human health problems and was banned in Canada.
Are they still using asbestos in building/construction products?
There is an operating asbestos mine in Quebec that exports their product to countries where asbestos is not banned. Their contention is that, properly handled, asbestos is not a health risk. In Canada and the US, asbestos has not been used since the mid 1970's. However, there remains an incredible volume of the material currently installed in thousands of buildings in dozens of different forms.
Where is asbestos typically found?
Some typical applications where asbestos may be found:
Residential:
Commercial
How do I know if I have asbestos in my house?
The first step is to have a qualified contractor or consultant visually inspect the areas of concern. In many cases, a visual inspection can provide sufficient basis for action. If there is doubt, the consultant can sample the suspected material and have it evaluated by a lab for asbestos content.
What is the procedure for removing asbestos? How much does it cost?
Asbestos removal is governed by the Ontario Ministry of Labour Regulation 278/05. This legislation specifies in great detail what procedures are required for a wide variety of asbestos removals. Essentially, the spirit of the legislation is to eliminate risk of fibre escape during and post-removal. As such, the standard of care for contractors is very high. Cost will vary on the nature, volume and location of the asbestos containing material.
If I'm careful, could I remove the asbestos myself?
Homeowners are not subjected to Regulation 278/05 and are legally free to do what they like within their own living space. Contractor workers receive significant training prior to working on removal projects. They are protected by adequate masks, suits and other equipment. Contractors are also trained and licensed to transport and dispose of asbestos.
Do-It-Yourself Asbestos removal is not recommended.
