Kirby Morgan 77
Some divers, keep the EGS gas cylinder
valve shut during the dive. Their rationale
being; in the event of an emergency, they
will simply open the EGS cylinder valve
thus eliminating any EGS air/gas unknow-
ingly being lost due to either a 1st stage
failure or EGS hose failure.
KMDSI strongly recommends never div-
ing with the EGS cylinder valve shut.
The reasoning behind this is twofold.
First, with the EGS cylinder valve open,
gas is immediately available in the event
of topside gas interruption via the EGS
valve on the side block simply by open-
ing it. Secondly, and most importantly,
if the EGS regulator (1st stage) is not
pressurized, during descent it is possible
that sea water will leak through the first
stage intermediate circuit and regulator,
causing failure of the EGS regulator if not
frequently serviced and resulting in pos-
sible injury or death.
WARNING
You can use a quick-disconnect whip to connect the
EGS valve to the bail-out bottle. This makes dressing
the diver much easier.
