Dryer Fire Statistics

Dryer fires are a cause of house fires that is more common than many home owners realize. Proper cleaning and maintenance of clothes dryers is the best way of avoiding this not so rare tragedy.

Every year in the U.S., there are an average of 13,000 house fires caused by clothes dryers. There are also approximately 370 injuries, ten deaths and $97 million dollars in property damage. Most of this damage and destruction is preventable by having the dryer duct cleaned regularly and the dryer serviced when it is not running correctly.

Causes of Dryer Fires

dryer lint buildupTypical consumer drying machines can be electric or gas; both types are susceptible to fire due to the combustible nature of accumulated lint build-up (see right). A dryer works by removing water from all the fabric placed inside the appliance. This process creates lint, which becomes compressed overtime in the ducts of the appliance.

A dryer has a motor that rotates the drum and a flame, or electric heating element, that dries clothing, towels and fabric. Both generate substantial heat (in addition to consuming large amount of electricity).

Good ventilation of this heat is needed so that the dryer will operate efficiently, as well as for safety. And if lint is causing a blockage, ventilation becomes virtually nonexistent.

Inadequate Ventilation

Unfortunately, dryers are typically installed in a tight location, such as in a closet or pressed up against a wall, which restricts access and ventilation. Obstruction of the dryer duct is the biggest cause of these fires. This problem accounts for over one third of all dryer fires. Lint is the biggest culprit for obstructing a duct. This is most common with flexible tubing, especially ones that are long, or have bends in them. Most homeowners assume that by simply cleaning out the lint trap after every cycle, they’ve eliminated all lint caught up in their machine. This is not the case. Lint, dust and debris builds up in the ducts as well as in and around the lint trap and is not easily removed. At least, not without the proper tools.

Clogged Ducts

Flexible ducts are prone to sagging, leading to a pile up of lint which then prevents the hot air from getting out. A blocked duct can cause overheating of the motor, which can then ignite lint and lead to a fire. This is especially true for condominiums and multi-story apartment complexes.

Bird Nests

As with lint build up, nests will keep air from flowing properly and the motor can overheat igniting material that has accumulated underneath the dryer.

Damaged or missing lint screens can also result in lint being drawn into the interior of the dryer and be another route to fire. Thermostats and limit switches that are malfunctioning are another source of fires, along with flexible ducts that get crushed.

How to Prevent a Fire

Indications that a dryer is not working right in ways that could lead to a fire include:

  • The dryer taking longer and longer to dry clothes;
  • Clothing that is still damp or extra hot when removed from a normal drying cycle;
  • A duct flap that does not open when the dryer is operating;
  • A low amount of air exiting the duct when the dryer is running.

The best ways of preventing a dryer fire are cleaning the lint trap every time the dryer is used and having the duct that leads outside cleaned and inspected at least once a year. More frequent cleaning might be needed if the dryer is used a lot. Replacing flexible tubes with ridged metal ducts makes it harder for material to build up and will also make cleaning easier. If there is a fire, metal ducts are more likely to contain it.

  1. This is a very important topic that everyone should be aware of and I’m glad I saw this because it’s been a while since we’ve cleaned the vents. The thought of a dryer fire really scares me

    • Hi. I have 14 years experience in duct cleaning. I can tell you for sure, that a dirty dryer duct is a hazard and it can cause a fire, on top of that it will make your dryer not work properly. In this video looks like the duct just goes true the wall and if you can move the dryer and clean it your self is OK, but in many more cases the dryer duct runs 15 to 25 up to the roof or side of the house or even under the property and for those cases you will need a professional with the right equipment.
