DRYER SAFETY TIPS

Thousands of home fires and injuries occur each year as a result of excessive heat buildup in clothes dryers caused by blockage of the airflow through the dryer and the attached venting system. Most of these fires could easily be prevented with simple and regular maintenance.

Lint screens and enclosures should be checked and cleaned after each load. Lint should also be regularly removed from accessible points at the dryer vent hose connection and exterior vent cover. Even with the regular cleaning of a dryer lint trap, it is possible for a significant amount of lint to accumulate at one or more points in the duct.

Vent system blockage also causes the dryer motor to work harder and possibly overheat. This excessive heat can result in the ignition of trapped lint or other combustible materials in or close to the duct or can prevent proper drying of the clothes – often the first sign of a problem with a dryer venting system.

The entire venting system should be periodically checked for damage, leakage, or blockage from lint, bird nests, rodents, etc. Any substantial blockage, whether from lint build-up or other restrictions in the vent hose or ductwork, such as crimped sections, undersized fittings, etc., will obstruct the airflow through the dryer as well as the venting system.

Lightweight, flexible plastic or aluminum vent materials are especially susceptible to blockage, damage, or burn though. Screws should not be used to hold sections together, as even only one screw can be enough to catch some lint, allowing for the build-up of lint that can eventually obstruct air flow. While more difficult to work with, solid, metal ductwork is the best option for dryer venting systems.

At least annually, the vent duct should be disconnected and cleaned out along its entire length, including the exterior damper and cover and portions of the system within the dryer itself (with electric power off). The base of vertical sections will likely contain the most accumulated material.

Remember, these tips are only general guidelines. Since each situation is different, contact a professional if you have questions about a specific issue. More home safety and maintenance information is available online at www.housemaster.com.
