    buffer = bumper
    some "caps" are more like valve bumper rings - you can install your nipple or regulator right through the opening.
    like these

    If you never have to remove the protective bumper ring then you don't have an unprotected valve, at least for the kinds of impacts the ring protects against. Caps can probably withstand dropping on the end better - at the expense of having to remove them to use and refill the tank.

    Hmmm.... here is my new mental image of how that might have happened. I was having trouble visualizing how the top of the cylinder could be pointed towards my midsection while moving it. But this says they were lowering/unloading the cylinders.
    Possible that they were being lowered to the ground from the back tailgate of a truck. Lever the lower end of a horizontal tank off the gate, use the valve as a handle/grip, and walk it forward as it tilts off the end towards an upright position. Could easily point the top of the tank towards yourself as you do so.

    Might not be the same incident, but the new article says one fatality and three injuries, even though the headline says two. And the violent, immediate release of pressure described in the first link fits within a definition of an explosion. Ignition is frequently part of an explosion, but is not a defining characteristic.

    The incident in India was September 29, the CTS report on October 7. The big difference is the narrative, CTS they describe the victim as moving a full bottle for transport, the incident in India describes a bottle exploding while a truck was being unloaded, no mention that it was even touched by the victim. Although I don't put anything past writers, I wouldn't expect a trade training bulletin to be that different when reporting in their own field.

    You got me on explosion, I guess I was looking for a bigger bang.

    Disagree again. In India “the driver-operator was killed... when driver-operators were unloading cylinders...”

    Two drivers in the space of a few days may not be an epidemic but I am sure it is more than would be expected or we would see this more frequently.
