What action should be taken if a tank has been out of use for an extended period?

When a tank has been out of use for an extended period, it is crucial to inspect, clean, and possibly decommission the tank to ensure safety and compliance with regulations. Over time, tanks can develop issues such as corrosion, leaks, and contamination. An inspection helps to assess the condition of the tank and identify any potential hazards. Cleaning is also necessary to remove any residual fuels, sediments, or contaminants that could pose risks if the tank were to be put back into service.

Decommissioning may be required if the tank is found to be unsafe for use or if it no longer serves a purpose. This process involves taking the necessary steps to properly close down the tank to prevent environmental impacts. Overall, this approach prioritizes safety and regulatory compliance, ensuring that the tank does not pose a risk to people or the environment.

In contrast, ignoring the tank or using it without inspection can lead to dangerous situations, while refilling it immediately without proper evaluation could result in spills or other serious incidents. Cleaning and inspection are essential steps to determine the tank's viability before any further actions are considered.
