Dryer Vent Fire Prevention

Dryer vent fires are now more likely than chimney fires in Canadian homes. And in the US each year, firefighters respond to nearly 15,000 home fires caused by clothes dryers, according to the National Fire Protection Association. These dryer fires account for nine deaths, 420 civilian injuries, and more than \$222 million in property damage.

The news isn’t all bleak, though. Prevention is key. With some simple tips and regular maintenance, you can substantially reduce the likelihood of a dryer vent fire and keep your family safe.

What Causes Dryer Fires and How to Prevent Them

The biggest potential fire hazard in a laundry room is lint. Lint builds up over time inside the dryer, lint trap, and especially the dryer vent system. When combined with restricted airflow, hot air, and static, lint build up becomes extremely combustible.

It’s not just the lint filter or lint trap that matters—the vent pipe, duct, and exhaust air system are critical. Exhaust ducts connected with sheet metal screws or flexible ducting can easily trap debris, dust, and lint. Blockage in these areas causes hot air and moisture to back up, reducing airflow and efficiency while raising the risk of a fire.

Other risks include improperly installed vent connections, unsealed joints, a damaged gas line, or a poorly designed exhaust vent. A dryer that isn’t operating in accordance with labeled instructions, industry compliance standards, or Consumer Product Safety Commission recommendations can expose your home to unnecessary risk.

Simple Tips for Prevention

• Clean the lint trap before or after every load of laundry. Waiting until “next time” or wondering when you last time cleaned it could be too late.

• Never leave the dryer running when you go to bed or leave the house.

• Ensure the lint filter is always in place when operating the machine.

• Don’t overload the dryer—too many clothes restrict airflow and generate excess heat.

• Have the dryer and ducting installed by experienced professionals to ensure security, safe connections, and proper exhaust air flow.

• Keep the area around the dryer free of flammable cleaning products or clutter.

• Make sure the outside vent is clear of snow, debris, or anything that restricts escaping exhaust air.

• Be extra vigilant in fall and winter, when dry air and static electricity make fires more likely.

These steps reduce operating risks and ensure your appliances work efficiently while keeping your family safe

Dryer Vent Cleaning Helps Prevent Fires

Even if you regularly clean the lint trap, lint and dust still accumulate inside the vent pipe and ducting. Blockage in the system prevents air from flowing as designed and creates dangerous hot spots. Signs you may need your dryer vent cleaned include:

• Clothes taking longer than usual to dry

• Condensation or moisture on walls in the laundry room

• Hot air escaping from connections

• A burning smell or excessive heat during a cycle

• Restricted airflow or reduced efficiency

If you notice any of these, it’s time for professional help. Dryer vent cleaning not only reduces fire risk but also prevents carbon monoxide leaks from gas dryers and improves energy efficiency.
