Madison,
In looking at your drawing, I do not see how the stored pressure can be vented immediately by opening the manually operated valve. Should there be a failure in either of the regulators, opening the valve leaves high pressure air still in the tanks. While that may have passed inspection at your events in 2012, I do not think it was legal in 2012 or now.

Please ask the question of the Q&A.
Al -- Unfortunately, pneumatics isn't my area of expertise, so I can't provide a definitive answer for your concern. I do know, however, that we were able to vent all the pressure from the system with the single release valve. I'll ask the folks who were responsible for this to provide some clarification. It may be that the system was changed after this schematic was created.
