Which resource does NOT provide information on the capacity of facility tanks?

The AAR-600 markings provide relevant information about the tank’s design and safety features, but they do not specifically offer details on the capacity of facility tanks. The AAR-600 is focused more on railroad tank cars and their compliance with safety standards rather than the specific operational capacities of tanks used in facilities.

On the other hand, facility operational manuals provide comprehensive guidance on the equipment's use, safety protocols, and capacity details. Manufacturer’s specifications are crucial as they usually specify the maximum volume and operational capacities of the tanks as designed by the manufacturer. Similarly, tank calibration records are essential for determining the actual usable capacity of the tanks, as they provide data on measurements taken and adjustments made over time to ensure the tanks are functioning correctly.
