What does an emergency shut-off valve do?

• A. It will shut off the flow of product in the event of a fire or if a car hits a dispenser.
• B. It increases flow during peak demand.
• C. It monitors fuel quality.
• D. It alerts emergency services.

Answer: (A)

An emergency shut-off valve is a safety device that quickly stops the flow of fuel when there’s a fire or a vehicle impact at a fueling site. It closes to cut off the supply from the tanks to the dispensers, helping prevent further fuel release and fire spread. It doesn’t increase flow, monitor fuel quality, or alert emergency services—those functions are handled by other parts of the safety system.
