The designated switch or circuit breaker to shut off power at a propane motor fuel dispenser must be located within what distance range from the dispenser?

• A. Not less than 20 ft and not more than 100 ft
• B. Not less than 10 ft and not more than 50 ft
• C. Not less than 30 ft and not more than 80 ft
• D. Not less than 5 ft and not more than 20 ft

Answer: (A)

Having a readily accessible emergency shut-off for a propane dispenser is a safety must. The required distance—between 20 feet and 100 feet from the dispenser—strikes a balance: it keeps the disconnect close enough to be reached quickly in an emergency, but far enough away to avoid damage or exposure from a fueling area incident and to stay clear of any spills or fires near the nozzle. This placement also helps ensure the shut-off remains reachable even if the dispenser area is obstructed by vehicles or equipment, so emergency responders and attendants can cut power without having to enter hazardous zones. Distances outside this range undermine safety: too close can expose the shut-off to damage or easy interference during a turn-off, while too far can delay stopping the electrical supply when a problem occurs.
