Abstract
- The proportion of submariners wearing eyeglasses has increased considerably in the last generation, raising the question as to how much leakage occurs when emergency breathing masks are worn over eyeglasses. The amount of leakage into the Oxygen Breathing Apparatus (OBA) was measured when it was worn over five different types of eyeglass frames as well as with no frames by shaven and bearded men. If the frame was small enough to fit under the mask, there was relatively little leakage compared with the other two masks carried on submarines. All the frames except the Standard Navy issues S-10 frame (which would not fit under the mask) were rated as reasonably comfortable, although the spectacle insert specifically designed to be used with the OBA was not rated as highly as the other frames. Originator supplied keywords include: Atmospheric contaminants, and Gas masks.
