Episode 06: What Does an E-Stop (Emergency Stop) Push Button Do?
In this episode, we discuss everything you need to know about E-Stops. Also known as an E-Button or E-Switch, this is an emergency shutoff located at the front of the building either 20 or 100 feet away from the closest dispenser required by the NEC and NFPA.
Pushing an E-Stop will instantaneously turn off all power to dispensers into the fueling system. This is important because if there is a fire or spark , the fuel will be shut off and will stop the flow.
Listen in and learn how to find and identify an E-Stop, what must be done if an E-Stop is switched, and more.

- An E-Stop forces you to be in a remote location to reset. You have to physically go look and see why something went wrong.
