Probably good thing Acetylene cylinders' have soft plugs in the bottoms or there may have been more and some even bigger explosions.
Can you imagine what kind of pressure some of those Oxygen cylinders must have reached?
Real scary!

The soft plugs on acetylene cylinders melt at a temperature near 300 degrees F. Having acetylene escaping into the atmosphere at its cylinder pressure of 250 psi creating auto ignition or spontaneous combustion. High pressure oxygen cylinders 2400 to 6000 psi with their bursting discs. Liquid oxygen. HOT FIRE!
It would be a great show for MYTH Busters to crack an unregulated, chained in place, acetylene cylinder and vent to atmosphere at 250 psi cylinder pressure. Also Set a cylinder on a heat source and increase temp to melt plug. Seeing would be believing.
Price of Acetylene on the way up??
