We hand the regulator second stage that we were breathing from (right hand takes the second stage from your mouth) to the "OOG" diver - this ensures that the OOG diver receives the appropriate gas from a working regulator. We don't use air.

Hahahaha! Very good sir!!

Yes, we donate what we're breathing, which is either EAN32, or trimix, or deco gas, never EAN21. As such using the expression "donate gas" is much more appropriate than "donate air," even though many people use that expression as a catch-all for all donations. Likewise, even though "OOA" is by far the most dominant expression describing someone who does not have access to whatever gas they are breathing, "OOG" is a more accurate description for someone known to be breathing something other than plain air.

In the sub-optimal case that a DIR team is in the vicinity of non-DIR divers, there is always the possibility of donating gas to an actual OO-Air diver, however absolutely no harm is done by using the expression "OOG" to describe a recipient of our kindness who happens to be diving 21/0.

This once again shows the deficiencies of lesser approaches. I recall taking a "NAUI Nitrox Diver" course, and the subject of donating enriched air to another diver came up. Naturally, they remind their students that it is safe to donate gas to another diver on 21/0. But they did not take the simple step of teaching us to use the expression "donate gas" for this procedure, nor did they teach us that our partners diving enriched air were likewise "OOG" instead of"OOA." Very sloppy. ;-)

Is he the one swimming at a 30-degree angle?

 

[LiteHedded]

he normally is
the gaiters are a dead giveaway too

Well, I'd like to think that "OOG" is a much more inclusive expression as it embraces whatever mix is used, even good old EAN21. "OOA" seems so discriminatory to mixed gas divers.
