Wow. I knew acetylene was dangerous, but I didn't realize it was THAT
dangerous. It's amazing that miners used to (and some spelunkers still) wear
acetylene generators on their foreheads!

Btw, I'm curious about these two safety statements:

"If this reaction or ignition occurs within the torch base or supply hose it
can propagate back into the storage cylinder causing it to explode
violently."

"Flame arrestors and check valves should be installed at both the torch base
hose connections and at the regulator hose connections."

In light of the former statement, wouldn't you also want a flame arrestor
installed at, or within, the cylinder valve?
