Kirby 77 User Manual

Kirby Morgan 77

Rapid ascent is dangerous. It can lead to

air embolism or decompression sickness.

Air/gas embolism can cause immediate

loss of consciousness and/or death.

Even on a no decompression dive, a

rapid ascent may cause decompression

sickness. A diver must only make a rapid

ascent when he is in immediate danger of

death by drowning or asphyxiation.

DANGER

Ditching the helmet underwater must be

avoided. If the diver ditches the helmet

underwater he will not be able to see.

In many instances, even if the air sup-

ply is interrupted, topside will be able to

get it back on line quickly. Do not ditch

the helmet underwater unless you are

completely out of breathing gas and it is

impossible to return to the surface due

to entanglement of your equipment or

similar circumstances.

DANGER

Never remove the diving helmet while

you are in the stage. If you fall out of the

stage with the helmet off but still attached

to your harness it may be very difficult to

swim. Drowning may result.

WARNING

3.11.4 Demand Regulator Free Flow

If the demand regulator free flows, turn the adjust-

ment knob in (clockwise) until it stops. If the free

flow cannot be stopped, the dive should be aborted.

Even if there is no serious problem to the diver, the

dive should be aborted and the problem with the

regulator corrected.

Sometimes it may be necessary to tilt your head so

the regulator is face up to help stop the regulator in a

free-flow situation.
