While it displaces moisture and provides temporary lubrication, its primary function is not long-term lubrication. This vaporization creates a combustible mixture in the air that can ignite, resulting in a flash fire.
Understanding WD-40's Ignition Temperature and Fire Risk
Therefore, the direct answer to the simple question is no, WD-40 in its container is not considered a flammable liquid. Consequently, using WD-40 on a hot engine is strongly discouraged and creates a significant fire risk, making it appear flammable in that specific scenario.
Ensure the surface you are treating has cooled down significantly before application. When WD-40 is applied to a hot surface, such as a recently run engine, an overheated motor, or an active welding spark, the extreme heat can cause the volatile components within the lubricant to vaporize rapidly.
Understanding WD-40's Ignition Temperature and Fire Risk
However, when it comes to safety, a critical question arises regarding its fundamental properties: is WD-40 flammable? Understanding the answer requires a closer look at its chemical composition, its intended purpose, and the specific conditions that define a flammable substance. Keep the can away from heat sources and store it at temperatures below 120°F (49°C).
