To prevent oil spills, where must outside tanks and piping be installed?

To prevent oil spills, the requirement for installing outside tanks and piping with a protective cover over tank valves and other essential components is significant because it mitigates the risk of spills caused by environmental factors or accidental damage. A protective cover acts as a safeguard against precipitation, debris, and other potential hazards that could compromise the integrity of the tank and its fittings.

This approach ensures that crucial components are shielded, which can help maintain proper function and reduce the likelihood of leaks. Effective protection of the valves and connections minimizes exposure to elements that might cause corrosion or malfunction over time, further enhancing safety measures.

Options suggesting other locations or arrangements for the tanks may not provide the same level of protection against spills and environmental impact. For instance, being in open areas might expose the tanks directly to weather conditions that could lead to damage, while placing tanks under a solid roof does not inherently provide the proactive defense that a protected valve offers. Elevated platforms, while providing some level of drainage and accessing, do not ensure safeguarding against spills from mechanical failure or environmental factors at the valve connections.
