Honestly, this backpack scares me from a safety perspective. What happens to the unlucky person wearing it if a tank should explode? As an LRI, I would insist it be removed from the venue, and I bet the UL Safety advisors would agree.
The solution to that safety issue is to put an OPV at every stage of the system, including one at each end of the tank, and set to 65% of the tank's pressure rating. This way, you have a redundant safety mechanism with about a 50% safety margin. With four tanks, you do this to each tank. In the case that a tank does fail, the frame of the pack should be designed to at least somewhat protect the user.
