What is the recommended procedure for refueling emergency vehicles?

The recommended procedure for refueling emergency vehicles is to engage safety protocols and turn off the vehicle. This approach ensures the safety of both the personnel involved in the refueling process and the vehicle itself.

Turning off the vehicle minimizes the risk of accidental ignition sources, such as electrical sparks or engine heat, which could ignite fuel vapors. Engaging safety protocols may include following specific guidelines to avoid spills, maintaining proper distance from sources of ignition, and using appropriate personal protective equipment to shield against exposure to fuels.

In contrast, continuing to run the vehicle while refueling could significantly increase the potential for dangerous incidents, as the engine's operation can create sparks or heat. Refueling without protective gear also poses a health risk to those handling fuel. Additionally, refueling only at night is impractical and does not address safety concerns related to the refueling process itself.
