Which statement accurately describes the range for the location of the emergency shutoff switch from the dispenser?

• A. Not less than 20 ft and not more than 100 ft
• B. Not less than 5 ft and not more than 15 ft
• C. Not less than 50 ft and not more than 200 ft
• D. Not less than 100 ft and not more than 200 ft

Answer: (A)

The main idea is to place the emergency shutoff switch at a distance that allows a quick, reliable shutoff without exposing the switch to the most dangerous area. A range of not less than 20 feet and not more than 100 feet from the dispenser achieves that balance: it keeps the switch within easy reach for the operator in an emergency, while not so close that it could be damaged or rendered unsafe by leaks, heat, or activity at the dispenser. If the switch were placed closer than 20 feet, it could be in the immediate hazard zone; if it were farther than 100 feet, reaching it quickly could be difficult and delay stopping the gas flow, increasing the risk.
