Fact Check: Can Oily Rags Really Cause a House Fire?
That bucket of dirty rags in your garage could be a liability.
Anyone who's ever stained wood or worked with paint thinner knows that the process can be messy. If you're like most DIYers, you probably have a pile of stained rags from various projects dedicated solely to these types of tasks. While you're careful not to light matches around an open can of varnish, you may not know that those oily rags can spontaneously catch fire.
Why Oily Rags Catch Fire So Easily
Oily rags are any type of cloth that has been used to apply a flammable substance like paint thinner, oil-based stains, linseed oil, or varnish. The danger lies in the fact that when these used rags are bunched up or left in a pile, the vapors can't dissipate properly. This can cause the rags to heat up and spontaneously combust.
Yes —seriously.
According to the NFPA, about 900 homes catch fire every year because of oily rags igniting.
How to Safely Store and Dispose of Oily Rags
The best way to avoid a problem is by taking proper preventative measures.
Don't:
- Toss the rags directly in the trash.
- Heap damp rags together in a pile or a container.
- Store used rags in a hot area or direct sunlight.
Do:
- Lay the rags out flat to dry in a well-ventilated area.
- Store used rags in a metal, airtight container filled with water and detergent. This will prevent oxidation/ignition.
- Follow the manufacturer's instructions for proper disposal.
- Contact your city's garbage disposal company when you're ready to dispose of any oily rags. The city may have special instructions for disposing of hazardous materials.
What to Do if a Fire Does Occur
If a fire does start, it's important to have a plan in place. These oil-based products are extremely flammable and flames can spread fast.
If the fire is outside, drench the flames with water or cover them with sand/dirt.
If the fire happens inside, get everyone out of the house and call the fire department. Use a fire extinguisher if the fire is still small. Otherwise, evacuate and wait for the fire department to arrive. Remember - things can be replaced, but people can’t!
