The evaluation was made to ascertain the operability of a deep sea helmet modified to permit direct return of the exhaust to the surface. If all exhaust gas could be piped back to the surface the acoustical noise emanating from the diver could be materially reduced. The unit as received from the manufacturer was found to be unsatisfactory in that there was insufficient exhaust capacity to permit the diver to descent and the helment relief valve was so constructed that it could not reliably be assembled.

The report discusses a simple, easily manipulated system for supplying the deep sea diver with an emergency, alternate air supply. The use of the commercial quick connect coupling fitted at the end of a standard lightweight oxygen/air hose and mating onto a modified spit-cock on the helmet provides an easy, safe method of furnishing an alternate air supply to a distressed deep sea diver. The modification proposed is within the capacity of forces afloat to accomplish, subject to the provision of a parts kit. It is recommended that the spit cock emergency supply system be made standard on all U.S.N. deep sea helmets. It is recommended that a conversion kit be furnished all diving activities to modify all existing helmets.
