O2 Dummy Light

I am wondering why the aforementioned diver did not catch the ppo2 fall???

Thanks Dad

Non-existent problem? Somebody better tell the admins that the Meg Pool incident is Fiction!

And I'm not sure how the chest falls within the central 30* of visual field with head stationary [Source: DOD, 1999 - Location of critical displays], also, any monitors or controls should not exceed a distance of 25 in. from the "reach and vision" of the user [Source: DOD, 1999; Ministry of Defence, 2000].

Just food for thought - Sure, someone can always figure out a way to kill themselves, but then again, how many arrestor cables are there on a flight deck?

And Downtime, I like the HH setup, but not all of us have it I was trying to think of a simple, fault-tolerant way of adding this type of alarm to any existing rebreather.[/quote]

I do have to admit there is a certain "ingenious" simplicity to your idea. You've obviously thought about the User Interface (UI) issues. (i.e. It has to be ON to dive, as opposed to it blinks red in a failure. Gets over the dead battery issue)

Dave is right. The ultimate responsibility is on the diver and no lights or bells will save an inattentive Rebreather diver.

On a Meg if your O2 is off you will evenually get multiple red lights on your HUD. So, at depth you would need to ignore your handsets and ignore your HUD, all of which is contrary to your training.

If you want to dive a Rebreather and survive you need to take full responsibility for yourself, never trust the machine for anything, validate mentally everything you see on your handsets and *always* assume the machine was built for the express purpose of killing you and the second you trust it, take it for granted or blindly depend on it it will do so.

I seriously vote for making this the #2 rule of CCR diving, right after "Know your pO2"

(although the marketing types may not like it )

CIS Mk-5P also features what was the worlds first multifunction HUD (and likely still one of the best), as well as a rear-mounted buddy-light (the first) AND an audible alarm (!) and with all of these the diver failed to receive sufficient indication.... draw your own conclusions.

No helping people who don't get it, and for those who *do* get it, very little indication is needed.
