What is the safe practice for refueling a chainsaw?

• A. Refuel indoors in a closed space with the engine running
• B. Refuel outdoors in a well-ventilated area with the engine running
• C. Refuel outdoors with the engine hot and no spill cleanup
• D. Refuel outdoors or in a well-ventilated area with the engine off and cool, and clean up spills promptly

Answer: (D)

Fueling a chainsaw safely hinges on controlling ignition sources and fuel vapors. The best practice is to refuel outdoors or in a well-ventilated area with the engine off and cool, and to clean up spills promptly. When the engine is off and cool, hot exhaust or nearby hot surfaces can’t ignite vapors, and you don’t risk starting a fire from a spark. Outdoor or well-ventilated areas disperse fuel vapors, reducing the chance they accumulate to dangerous concentrations. If a spill happens, wiping it up right away prevents fuel from spreading, soaking into surfaces, or contacting ignition sources, and helps protect the environment.
