Dryer fires happen when lint, which is the small fibers that come off clothing during the drying process, builds up inside the machine or in the venting system. Lint is highly combustible and can easily catch fire if it comes into contact with heat or an ignition source.
One of the most common causes of dryer fires is a clogged lint filter. If the filter is not cleaned before and after each load of laundry, lint can accumulate and block the flow of air through the machine. This can cause the dryer to overheat and potentially catch fire.
Another major cause of dryer fires is a clogged dryer vent or exhaust duct. Lint can accumulate in these areas over time, particularly if they are not cleaned regularly. Dryer ventilation should be professionally cleaned and serviced at a minimum of once a year to avoid buildup. When ignored this can cause a dangerous buildup of heat and can lead to a fire.
It's also possible for dryer fires to happen due to mechanical issues such as a malfunctioning heating element, a damaged thermostat or a malfunctioning sensor. These types of issues can cause the dryer to overheat and potentially catch fire.
It's important to note that dryer fires can also happen due to user's error such as overloading the dryer, using the wrong type of venting material, or leaving the dryer running when you are not home.
Here are a few steps you can take to prevent dryer fires:
- Clean the lint filter before and after each load of laundry.
- Have your dryer vent and exhaust duct cleaned regularly to remove any lint buildup.
- Make sure the outdoor vent hood flap opens when the dryer is in use.
- Don't overload the dryer and allow enough space for air to circulate around the machine.
- Have your dryer itself inspected and cleaned by a professional every year.
- Use only the type of venting material recommended by the manufacturer.
- Keep the area around the dryer clean and free of clutter.
- Don't dry items that have been cleaned with flammable liquids.
- Do not leave the dryer running when you are not home.
- If you notice any unusual noises or smells coming from the dryer, stop using it and have it inspected by a professional.
