True or False: A properly functioning valve is sufficient protection against leaks of flammable materials in a tank loading line.

A properly functioning valve, while important, does not provide sufficient protection against leaks of flammable materials in a tank loading line on its own. Valves can fail due to various reasons, such as mechanical wear, corrosion, or improper installation. In addition, leaks can occur around the valve itself, at the connections, or elsewhere in the piping system.

To effectively manage the risk of leaks, comprehensive safety measures must be implemented beyond just relying on valves. This includes regular inspections, maintaining secondary containment systems, using proper materials that are compatible with the flammable substances being handled, and ensuring adherence to strict operational procedures.

Moreover, systems should incorporate additional safety features such as leak detection systems and emergency shutoff valves to enhance overall safety. Thus, while valves are an important component of leak prevention, they cannot be considered sufficient by themselves without a holistic approach to safety management.
