Key Safety Tips to Prevent Dryer Fires:

[ReginaldCannon]

Clean the lint trap: Remove lint after every single load of laundry.
Clean the vent pipe: Have your dryer vent pipe inspected and cleaned by a professional at least once a year.
Use proper venting: Use rigid or semi-rigid metal venting material, not plastic or foil, as these can crush and trap lint.
Do not overload: Overloading restricts airflow, forcing the dryer to overheat.
Don't leave running unattended: Avoid running the dryer while you are out of the house or asleep.
Check items: Be careful drying materials with foam, rubber, or plastic, and never dry items soiled with volatile chemicals like oil, gasoline, or cleaning agents.

I was surprised to learn that can a dryer catch on fire. It turns out that the main cause of such fires is lint accumulation in the ventilation system. This makes sense, as lint is very flammable. Now I understand why many experts recommend cleaning the ventilation system regularly. After reading the article, I checked my duct for the first time and found that it was indeed quite clogged.
