Results of a National Fire Protection Association (NFPA) study* estimate 16,800 home fires are caused annually by washers and dryers in the United States. Household dryers were directly responsible for 92% of the reported fires. The leading cause reported as “a failure to clean”. These fires come with serious consequences including 51 deaths, 380 civilian injuries and $236 million dollars in direct property damage.

These hazards can be greatly reduced utilizing approved installation practices, proper dryer maintenance, installing electronic monitoring, and performing regular dryer vent cleaning. All fires require three things to be present, oxygen (air), heat/ignition source (dryer heat whether gas or electric), and fuel (clothes/dryer lint). Remove any one of these three items and a fire will simply not burn.

Hundreds if not thousands of tiny clothing fibers are released each and every time you use your dryer. These fibers are designed to be collected and disposed of through regular cleaning of the dryers lint trap/filter. Some of these fibers however make it through the lint trap/filter and begin to collect on the moist walls of the dryer vent duct work. Over time these fibers accumulate and restrict the airflow needed to exhaust the dryer. This results in temperatures high enough to ignite these clothing fibers and start a fire in your home.
