Where should non-essential passengers stand during a boat fueling process?

During a boat fueling process, non-essential passengers should remain on land or at a safe distance from the fueling area, typically at least 15 feet away. This precaution minimizes the risk of accidents, such as spills or fires, and ensures safety for everyone involved. Passengers should also avoid using any electronic devices or open flames while fueling is in progress. Always follow the crew's instructions and safety guidelines during this time.
