CHECK SPG ON LEFT FIRST STAGE
If it decreases rapidly the leak is somewhere on the left sideIf it remains constant the leak is on the right side

RIGHT CYLINDER WILL EMPTY YOU’VE SAVED THE LEFT
WORSE STILL – YOU BREAK THE MIDDLE
Somebody carries the twinset by the manifoldYou bump the manifold inside a wreck

Doesn’t matter if isolator valve isOPEN or SHUT
YOU LOSE ALL GASES FROM BOTH CYLINDERS
RESULT ?
You bump the manifold inside a wreck
Somebody carries the twinset by the manifold
THEY DIE !!
YOU DIE !!!!
