Emergency shut offs must be located how far from the point of liquid transfer?

Emergency shut offs are critical safety features in facilities where liquid fuel is transferred. The regulations regarding their placement are designed to minimize risks in the event of a leak or spill during the transfer process. The correct choice indicates that emergency shut offs must be positioned a minimum of 25 feet and a maximum of 100 feet from the point of liquid transfer.

This range allows for a safe distance that ensures personnel can quickly and effectively shut off the fuel source in an emergency without being placed too far away, where immediate access might be hindered. Additionally, it provides adequate space to reduce the risk of ignition or accidents resulting from an emergency situation.

In comparison, options that suggest a distance either too short or too far do not align with standard safety practices that dictate how to manage hazardous materials safely. This particular choice balances accessibility with safety.
