Cleaning Your Dryer Vent
The National Fire Prevention Association recommends that you have your dryer vent cleaned once per year. The US Consumer Product Safety Commission says "The U.S. Consumer Product Safety Commission estimates that in 1998, clothes dryers were associated with 15,600 fires, which resulted in 20 deaths and 370 injuries.
Dryer Vent Fires
Fires can occur when lint builds up in the dryer or in the exhaust duct. Lint can block the flow of air, cause excessive heat build-up, and result in a fire in some dryers. Lint believe it or not is extremely flammable, and is carried by survivalists to start fires in even wet conditions.
If your dryer is not drying your clothes in one full cycle, this is a strong indicator that your dryer vent is clogged and you may have a potential fire hazard in your home.
