At a motor fuel dispensing station, hose length may NOT exceed what without AHJ approval?

At a motor fuel dispensing station, the maximum allowable hose length without the approval of the Authority Having Jurisdiction (AHJ) is specifically set to ensure safety and manageability. A hose length of 18 feet is established as a standard limit because longer hoses can introduce additional risks such as increased potential for leaks, higher chances of physical damage, and difficulties in handling.

Longer hoses can create complications in maintaining proper connections and can make it harder for users to control the dispensing process, potentially leading to spills or accidents. Having a standardized maximum hose length helps to ensure that dispensing is done safely and efficiently while also facilitating compliance with regulatory standards and best practices within the industry. This is why the limit is set at 18 feet without requiring additional approval from the AHJ, whose role includes overseeing such safety standards.
