Maybe you can fill us in one the last time an explosion occurred, and then you 
could go down to Trigas, where I get mine, show them your weenie card, and tell 
them you would like to inspect the fifty bottles they are jamming at a time
with 
2600 psi of pure O2. Get serious - the bullshit on this subject really has to 
stop. If you don't know what the fuck you are talking about, don't say
anything.
