Flammable Liquid & Oily Rag Safety

How Can Oily Rags Start a Fire?

The oils commonly used in oil-based paints and stains release heat as they dry.  If they’re thrown into a pile, oxygen is trapped underneath.  The combination of heat, oxygen and the cloth can lead to spontaneous combustion, which results in a fire that could destroy your home.

How Can Flammable Liquids Start a Fire?

Vapours from flammable and combustible liquids can ignite, causing a fire. There are many commonly used flammable liquids including gasoline, paints and laquers. Examples of combustible liquids include paint thinner, stains and kerosene.

How to Store & Dispose of Oily Rags:

• Never leave wet rags in a pile.  Used rags should be spread out in a safe area to dry and weighed down so they don’t blow away.
• Store the dry rags in ULC certified, non-combustible metal container with a self-closing lid.  Fill the container with a water and detergent solution which will break down the oils.
• Keep containers of oily rags in a cool place out of direct sunlight, and away from any heat sources.  Check with your city or municipality for disposal instructions.
• Follow the manufacturer’s recommendations. Since manufacturers use different oils in their products, it’s important to follow their warnings and disposal instructions.

Flammable & Sombustible Liquid Safety

• Flammable and combustible liquids should not be used near an open flame.  Do not smoke when working with these liquids.
• If you spill liquids on your clothing, remove the items and dry them outdoors.  Once dry, the clothing can be laundered.
• Keep liquids in their original containers with lids or caps tightly sealed.  Never store liquids in glass containers.
• Never use gasoline as a cleaner or to break down grease.
• Store gasoline only in a container that is designed for that purpose and keep the container tightly capped when not in use.
• Never store gasoline containers in an occupied building.  Gasoline should be stored in a detached garage, shed or outdoors, away from any heat sources.
