Could your hot air furnace contain an asbestos heat shield?
Asbestos Heat Shield in Furnace
Health Canada banned asbestos heat shields in hot air furnaces in the early 1980s. The big problem following this ban, is that the average life of a furnace is 50 years or more. Many of these furnaces are still in use, and when the gasket breaks down it can circulate deadly asbestos fibers throughout your ductwork and home.
Some of these older heat shield gaskets are made up of 30% chrysotile asbestos. If your gasket is showing signs of breaking down or deteriorating it must be replaced by a professional. The heat shield gasket is suspended between the metal face plate and the furnace box. These gaskets are connected to a blower in the furnace and if deteriorated it could release microscopic asbestos fibers into the air that can travel through your home and into your lungs. This can lead to mesothelioma or asbestosis, which impairs lung function, and is incurable or can cause a number of lung cancers.
As long as the heat shield gasket is in good condition, it is safe and is not a health risk or a risk factor to the homeowner or to the people working on the system. The gasket becomes an issue when it’s disturbed or is breaking down. Especially if you’re in a damp climate or the furnace has not been used for long periods of time, which can accelerate deterioration.
If your hot air furnace was produced before the 1980s, contact the manufacturer or call Stutters and have the gasket inspected for asbestos.
