Self-ignition of combustible material through chemical action (such as oxidation) of its constituents. Called also spontaneous ignition.
How does spontaneous combustion occur?
- All fires, including those ignited spontaneously, require three elements. (Source: https://www.thespruce.com/preventing-home-and-workshop-fires-1398180)
- Heat source (no flame causing the heat)
- Flammable finishes like linseed oil or tung oil combine with air and oxygen in a natural chemical reaction that creates heat. (Source: https://www.thespruce.com/preventing-home-and-workshop-fires-1398180)
- The most common type is caused by improperly disposing of oil-based paints, stains, tea, linseed oils, varnishes, polyurethane, and paint thinners. (Source: https://www.essexct.gov/fire-marshal/bulletins/rise-in-fires-due-to-improper-disposal-of-oily-rags)
What are examples of spontaneous combustion? (Source. https://www.nps.gov/articles/fire-prevention-52-spontaneous-combustion.htm)
- Rags and towels soaked with oils, including cooking oils.
- Hot laundry left in piles.
- Large piles of compost, mulch, manure, and leaf piles.
- Moist baled hay, in the right conditions.

How do you properly dispose of rags/towels to reduce spontaneous combustion? (Source: https://www.thespruce.com/preventing-home-and-workshop-fires-1398180)
- Hang oil-soaked rags/towels up to dry, preferably outdoors.
- Isolate each rag/towel individually.
- Don’t pile rags/towels on top of each other.
- If rags/towels are hung up indoors, keep them away from heat sources, such as water heaters or furnaces.
- Once rags are dry, throw them away in a trash receptacle that is outside and away from any structures.
