This is a good point but it has a simple solution. NEVER hook up both inflators on a dual bladder wing.
Or get one of those cheap in-line shut-off valves and keep it normally set on closed.

Xdeep Stealth 2.0So what wing are you using?
LeftWhat cylinder is feeding your power inflator?
The exhaust valve is on the bottom, so runaway inflator you kick down while dumping with one hand (right), disconnect the inflator hose with the left.And what was the specific protocol taught in your deco class for a runaway inflator?
Instructor flips underneath you, blasts your LPI. But I confess this was not under stress. That is one of the strengths of the DIR programs: demonstrating proficiency under stress built into the program. Like I have said in other posts: when it comes to tech training in Seattle, the best instruction is at 8.And how was this protocol proofed in the real world? - ie how did you demonstrate proficiency under stress.
How do your disconnect with one hand? The DSS hose hat? Is the inflator clipped off that tight?
I can tell you everyone I have ever known to have taken UTD or GUE T1 level classes (10+ years worth of students) has corked before being able to successfully disconnect a runaway power inflator (this is a shallow water, 30ft deep, exercise but they also usually go for it with 2 hands). There is a long history of not trying to disconnect as it never seems to actually work this way in practice. 1) Kick down, 2) shut down the right post 3) while dumping from the left butt dump, 4) switch to backup reg once you have breathed down the right post.
Deep Sea Supply used to make this little plastic dohicky that went over the BC hose flange
You can still find them even though Tobin retired

XScuba calls them "easy grippers"

Oh I soooo want someone to show up with one of these at the next GUE-F class

Its another thing to leakWhat’s the problem with the valve? Worst thing it does is fail closed. Then you have to remove it and replace the hose or manually inflate.
There are no serious failure modes to thatt piece of gear and it would prevent a run-away inflator. I am failing to see the downsides.
