Prevent Clothes Dryer Fires

Make sure the dryer vent is made of solid metallic material.
The dryer vent system should vent to the exterior and in no case should it vent to the attic or crawlspace.
If you want to save space, use a dryer box that allows the dryer to be safely installed against the wall.
Minimize the length of the exhaust duct (be compliant with the codes in your area) ,If this is not possible, you can install a dryer vent booster fan.
Use 4-inch diameter vent pipe and exterior exhaust hoods that have openings of sixteen square inches or more, which offer the least resistance to air flow.
Don’t use screws to put your vent pipe together – the screw shafts inside the piping collect lint and cause additional friction.
Keep Your Dryer as Lint-Free as Possible
By keeping your dryer clean, not only will you significantly reduce the fire hazard, you will also save money as your dryer will run more efficiently and last longer. To keep your dryer clean:
Use a lint brush or vacuum attachment to remove accumulated lint from under the lint trap and other accessible places on a periodic basis.
Every year, depending upon usage, have your dryer vent cleaned by a qualified service technician. This will reduce the fire hazard, increase the dryer’s efficiency and increase its lifespan. In addition, you are less likely to experience water damage.
