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.
