Generators become hot while running and remain hot for long periods after they are stopped.
When spilled on hot engine parts, generator fuels (gasoline, kerosene, etc.) can ignite and cause an explosion. If your generator has a detachable fuel tank, remove it before refilling. If this is not possible, shut off the generator and let it cool before refilling.
Gasoline and other generator fuels should be stored and transported in approved containers (properly designed and marked for their contents), and vented.
Do not store generator fuels in your home. Store fuels away from living areas.
Keep fuel containers away from flame producing and heat generating devices such as the generator itself, water heaters, cigarettes, lighters, and matches. Do not smoke around fuel containers – escaping vapors or vapors from spilled materials can travel long distances to ignition sources.
