An identified and accessible ______ shall be installed at a location not less than 20 feet or more than 100 feet from the dispensing device to shut off the power in the event of a fire, accident, or other emergency.

An identified and accessible ______ shall be installed at a location not less than 20 feet or more than 100 feet from the dispensing device to shut off the power in the event of a fire, accident, or other emergency.

• A. Fire Alarm
• B. Emergency Shut Off
• C. Power Disconnect
• D. Emergency Stop

Answer: (B)

The main idea is having a clearly marked control that can quickly cut electrical power to the dispensing system in an emergency. This shut-off device must be identified and accessible so responders or on-site personnel can reach it without delay and from a safe distance. Placing it not less than 20 feet and not more than 100 feet from the dispensing device gives a balance: it’s close enough to reach quickly during a fire or accident, but far enough to reduce exposure to the immediate danger at the dispenser. The option that fits this purpose is an Emergency Shut Off—the designated control used to disconnect power rapidly in an emergency to stop electrical power to the dispensing equipment. A Fire Alarm is for alerting people and does not shut off power. An Emergency Stop is intended for halting machinery or a process that can be safely stopped at a control panel, not for isolating the entire dispensing system’s power. A Power Disconnect could accomplish the same hardware function, but the terminology and typical safety practice call for an Emergency Shut Off as the installed safety device for rapid power isolation.
