What is the maximum distance that emergency controls for an attended self-service motor fuel dispensing facility shall be located from the dispensers?

The correct answer identifies that the maximum distance emergency controls for an attended self-service motor fuel dispensing facility must be located from the dispensers is 100 feet. This regulation is established to ensure the safety of both the customers and the facility staff. By having emergency controls within this specified distance, it allows for quick and effective response actions in case of an emergency, such as a fire or fuel spill. This distance ensures that emergency responders or personnel can access controls swiftly while being close enough to monitor activities at the dispensers, without putting themselves in potentially hazardous situations.

Setting the maximum distance at 100 feet strikes a balance between accessibility for immediate response and minimizing exposure to risks associated with motor fuel dispensing operations. A greater distance could delay emergency response times, which is critical in high-risk environments like fueling stations.
