Home renovations trend raising risk of toxic asbestos exposure

A new WorkSafeBC campaign is cautioning homeowners undertaking renovations and demolitions that could release deadly asbestos in homes built before 1990.

While television, internet tutorials and a robust do-it-yourself culture make home renovation more appealing than ever, a new WorkSafeBC campaign is telling homeowners to hit pause before proceeding.

That's because houses built before 1990 may have been built with a wide range of materials containing deadly asbestos and renovations can release the toxic fibre into the air.

Al Johnson, the vice-president of prevention services at WorkSafeBC, told CBC's The Early Edition asbestos was used in many different ways in older homes — in pipe insulation, vinyl tile, linoleum, textured ceilings, wiring and spray insulation.

"That asbestos, in those materials when left alone, is okay. It's not going to harm you and it's not going to come out of that material," he explained.

"But if you disturb the material and if you break it into smaller pieces — like what you do in a demolition or renovation — that's when those fibres can be released into the air."

Breathing in asbestos fibres can cause lung scarring and in extreme cases a deadly form of lung cancer called mesothelioma.

Tracy Ford, the co-founder of the Asbestos Related Research, Education and Advocacy Fund, described how her father — an electrician who worked in pulp and paper mill — succumbed to the disease.

"There are no cures. They tried to prolong his life through chemotherapy and he actually had surgery to remove the lining of his lungs. They gave him about a year to live and he lived about 16 months. It was a difficult 16 months for everyone and there wasn't quality of life."

Johnson said it is important for homeowners to exercise caution before proceeding and have a qualified professional test their house for asbestos. If asbestos is found, he said, have a qualified team remove it safely.

"If you know what's there you can protect yourself," Ford said. "You can have it properly removed or you can change your renovation plans and actually not remove it."
