The main cause of home clothes dryer and washer fires is failure to clean them properly.
Have your dryer maintained and installed by a professional technician.
Do not use the dryer without a properly working lint filter.
Make sure you clean the lint filter before or after each load of laundry. Remove the excess lint that has collected around the drum.
Sturdy flexible metal venting material needs to be used to ensure proper air flow and drying time.
Make sure the air exhaust vent pipe is not clogged and the outdoor vent flap will open when the dryer is running. As time goes on you may notice that it is taking longer than normal for your clothes to dry; you need to clean lint out of the vent pipe or have a professional dryer lint removal service do it.
Keep dryers in good working order. Gas dryers need to be thoroughly inspected by a professional to ensure that the gas line and connection are intact and free of all gas leaks.
Make sure the correct plug and proper outlet are used and that the machine is properly connected.
Follow all the manufacturer’s operating instructions and DO NOT overload your dryer with too many clothing items.
Never run your dryer if you are leaving home or when you go to bed.
