Across the country, an average of 900 home fires per year are started when oil rags catch fire or are ignited through the process of spontaneous combustion or chemical reaction according to the National Fire Protection Association. The Bloomington Fire Department would like to provide the following safety information regarding oily rags. Oil-based paints, stains, and varnishes are often used for home improvement projects. It is common to use rags to wipe up spills or clean brushes. But wet rags can ignite on their own. They can start a fire if not handled carefully.
Be safe
The oils commonly used in oil-based paints and stains release heat as they dry. If the heat is not released in the air, it builds up. That is why a pile of oily rags can be dangerous. As the rags dry, the heat is trapped. The heat builds up and finally causes a fire. Be aware that this does not happen with water-based finishes.
Follow these simple fire safety tips:
Never leave cleaning rags in a pile. At the end of the day, take the rags outside to dry.
Hang the rags outside or spread them on the ground. Weigh them down. Do this so they do not blow away. Make sure they are not in a pile. Keep them away from buildings.
Put dried rags in a metal container. Make sure the cover is tight. Fill the container with a water and detergent solution. This will break down the oils.
Keep containers of oily rags in a cool place. Keep them out of direct sunlight. Keep them away from other heat sources.
