Andrasik, Maria. Tumbler Fires. International Fabricare Institute Bulletin.

Abstract: Fires can start in dryers for a number of reasons. Lint build-up is one major cause because it blocks airflow and allows the temperature inside the unit to rise. The overheating results in the fabrics melting and possibly igniting. Lint can also accumulate in the safety thermostat causing it to give false readings, which could lead to overheating.

Fires can also start in hampers or carts after the fabrics are removed from the dryer. If no time is allowed for cooling the hot fabrics their temperature can increase in the hamper because there is no air circulation. Smoldering occurs with no signs of smoke until it reaches the top of the hamper or cart. Once it reaches the top, the exposure to oxygen causes the fabrics to ignite. The flames will re-burn the smoldered fabrics giving the fire strength to spread.

To prevent these fires make sure the lint strainer is cleaned regularly and keep the thermostat free of lint. Also, run hot loads through a cool down cycle before removing them from the dryer.
