| Navy Rescue Breathing Apparatus, Patrol Model 1 |
| |
|
The patrol type breathing apparatus was in service
through the mid 1950s, when it was phased out and
discontinued. It allowed 45 minutes of breathing air.
The rubber face piece had head straps, a set of plastic
eyepieces, a speaking diaphragm, a rubber mouth piece
and a timer. It created a closed, self-sustaining system
once the canister was inserted and activated. The air
bag had to be inflated prior to activating the canister;
when expended, the new canister had to be changed in
fresh air. The apparatus was mounted on a central
casting and attached to the body with shoulder straps,
and a jacket-styled air bag covered the front and went
across the back of the wearer. It had no safety-line
ring or harness. |

The Model I of the Navy Oxygen Breathing Apparatus
Patrol Type was a self-contained oxygen generating
breathing apparatus designed to protect the wearer in
any atmosphere that is irrespirable due to presence of
harmful gases, vapors, dusts and smokes or a deficiency
of oxygen. It is entirely self-contained and its
operation is independent of any outside air; the wearer
breathes in a closed system which forms a circuit within
the apparatus. The exhaled air which contains carbon
dioxide is purified of this -ga.s and replenished with
oxy.gen by passing through a chemical and is then
rebreathed. |
