What must the automatic dispensing system incorporate for safety?

A pull-away device
A remote sensor
An audio alarm
A manual shutoff switch

The correct answer is: A pull-away device

An automatic dispensing system must incorporate a pull-away device for safety to help mitigate risks during the refueling process. A pull-away device ensures that the fuel hose detaches automatically if a vehicle accidentally drives away while still connected to the dispenser. This mechanism is crucial because it prevents potential spills, fires, and other accidents that could arise from an improper disconnection. In the context of safety features, a pull-away device acts as a safeguard against human error, ensuring a rapid response to prevent hazardous situations. While other options, such as remote sensors, audio alarms, and manual shutoff switches, contribute to the overall safety and functionality of the system, the specific function of preventing dangerous scenarios resulting from a connected vehicle driving off is fundamentally addressed by the pull-away device.
