Manned Evaluation of the EX 15 Mod 1 UBA (Underwater Breathing Apparatus) Carbon Dioxide Absorbent Canister.

Abstract

Manned canister duration studies using the EX 15 Mod 1 UBA were conducted at 3 different exercise levels; rest, 50 watts intermittent work and 100 watts intermittent work. Studies were conducted at a depth of 566 FSW using a breathing mixture of 0.7 ATA in nitrogen. Conclusions from this study were 1) The recommended EX 15 Mod 1 canister duration for most diving operations is 280 minutes independent of water temperature; 2) The recommended EX 15 Mod 1 canister duration for divers in a resting scenario, such as riding in an SDV, is 480 minutes independent of water temperature; (2) Canister duration was observed to have an inverse relationship to diver oxygen consumption, with the decrease in canister duration proportional to the increase in oxygen consumption.
