So our procedures do take account for lost buddies but it doesn't really happen. However we do calculate and carry the gas supply needed to safely take 1 diver to their next gas source.
What do the other agencies recommend about gas for your dive buddy if he were to suffer a catastrophic gas loss?

What I got taught sounds not dissimilar to the above only with some faffing time added in on the bottom as well to sort stuff out. That was IANTD circa 1994 and the instructor I was using was one of the founding members of IANTD UK who had been trained under Billy Deans (as to why that was relevant, a lot of Capt Billy's standard procedures found their way into the WKPP & prehistoric DIR). What's in the manual I don't know because they were never well known for being exhaustive but that's more or less what we had to plan our dives for (and IIRC we did quite a few dives where the deco bottle was "failed"). We weren't taught the sharing deco gas procedure GUE uses but we were taught not to leave a buddy on an extended stop if a deco bottle fails. If one of you is on an extended schedule then both of you is. When I first read about the GUE procedure I thought it made a hell of a lot more sense and started using that. Thankfully, outside of training I've only once had a complete, unsalveageable deco gas reg failure and once lost a bottle completely
