What is the minimum acceptable condition for an ASME propane container before filling?

The minimum acceptable condition for an ASME propane container before filling is that it should be visually inspected. This visual inspection is crucial because it helps to identify any visible signs of damage, corrosion, or leaks that could pose a safety hazard during the filling process and subsequent use of the propane. Inspecting the container ensures that there are no apparent issues that could affect its integrity and performance, which is a key safety measure in handling propane.

Although having a current data plate, detailed documentation, and a recent testing history are all important aspects of maintaining ASME propane containers and ensuring compliance with regulations, they are not the minimum condition necessary for the immediate filling of the container. The visual inspection acts as the first line of defense in ensuring the container can safely hold propane before it is filled.
