Why Asbestos Removal Is Needed For Demolition
Asbestos was a popular building material in the years before 1990. This is because it has very good properties including resistance to corrosion, poor heat conductivity, and high tensile strength. However, health experts discovered that asbestos was linked to several ailments among them lung cancer. This is because asbestos releases fibers whose harm accumulates in the long-term in the people living in close proximity. This health hazard is also why asbestos removal is needed for demolition.
Where can asbestos be found?
Asbestos was popularly used as a roofing material. It can also be found in:
- Exterior stucco and siding
- Furnace/boiler duct tape

What are the harmful effects of asbestos?
Asbestos gets into the human body when asbestos fibers in the air are breathed in. these fibers accumulate in the lungs since asbestos is non-biodegradable. In the long-term, these asbestos deposits in the lungs cause scarring and inflammation. Some of the ailments that have been linked to exposure to asbestos include:
- Lung cancer
- Larynx cancer
- Ovary cancer
- Pleural disease
How does asbestos exposure happen?
- During hand demolition of building materials containing asbestos
- Demolition using asbestos-containing buildings using methods that raise dust like crane and ball

Can asbestos exposure be controlled?
It is a legal requirement for asbestos to be handled safely during a demolition. In Calgary, any demolition must acquire a permit. One of the documents to be attached when applying for this permit is the Asbestos abatement form. This is where the applicant explains the measures put in place to ensure there is no exposure to asbestos.
The asbestos-containing building materials must be removed before the demolition begins. Asbestos removal should be done by a trained and competent professional.

The Provincial Dangerous Goods Transportation and Handling Act and the Dangerous Goods Transportation and Handling Regulation describe the manner in which asbestos and asbestos-containing debris and waste should be handled.
