If an ASME tank's data plate is missing or illegible, what must be done?

When the data plate on an ASME tank is missing or illegible, it is crucial to refuse to fill the tank. The data plate provides vital information about the tank's specifications, including its design, capacity, and safety features. Without this information, there is no way to verify that the tank meets safety and regulatory standards. Refilling a tank that lacks clear identification and safety data poses significant risks, including potential overfilling or use beyond its designed parameters, which can lead to dangerous situations such as leaks or explosions. Prioritizing safety and compliance with regulations is vital in such circumstances, making it essential to refrain from filling the tank until its status can be properly assessed.
