WebFlammable fuels have a flashpoint below 38°C. and combustible fuels have a flashpoint above 38°C. As an example, diesel fuel flashpoints range from about 50°C. to around 100°C making it relatively safe to transport and handle. Gasoline, by comparison, has a flashpoint of minus 43°C. Sparks and static electricity can easily ignite gasoline fumes.
