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

The requirement that remote shut-offs must be located between a minimum distance of 3 feet and a maximum distance of 100 feet from the point of liquid transfer is based on safety regulations designed to protect personnel and the environment. This distance ensures that in the event of an emergency, operators can quickly and safely shut down the flow of fuel without being in immediate danger from hazards such as spills or fires.

Maintaining a minimum distance helps mitigate risks while also allowing sufficient space for emergency responders to operate safely. The maximum distance permits flexibility in various installation scenarios, ensuring that the remote shut-off is readily accessible even in larger spaces. This balance of safety and accessibility is critical in fuel transfer operations, where quick response to potential issues can significantly reduce the risk of accidents and environmental impact.

Other distances provided in the options do not align with the current safety standards set by regulatory bodies, which necessitate the specified range of distances to ensure effectiveness in emergencies and compliance with safety regulations.
