This is one of the most commonly misunderstood RMP/PSM compliance issues for facilities that use rail cars as storage tanks and or use “tube trailers” as storage tanks.

A five-pound CO2 cylinder being stored in a compressed gas storage cage at a power plant failed catastrophically and became a missile. The cylinder destroyed the storage cage, then struck one of six stationary hydrogen storage cylinders used as emergency make-up for the hydrogen supply system. One of the hydrogen cylinders was broken away from its mounts and moved 10 feet from its original location....

Here is a list of questions investigators may ask to determine whether line management deficiencies affected the accident. These questions are based on the seven (7) guiding principles of an SMS.
