Title:	MK 12 Surface Supplied Diving System Helium-Oxygen Emergency Mode Study
Author:	Spaur, WH; Thalmann, ED; Maulbeck, RC
Abstract:	This experiment tested the duration that respirable gas would be available in the MK 12 helmet when gas supply from the umblical has been stopped. The emergency mode semi-closed recirculator operation was tested in 40 F (4.5 C) water in a wet chamber at depths of 390 and 80 FSW. The duration of reasonable life support was considered to be the time between shut-off of the umbilical supplied mixed-gas and the time when the helmet gas reached 3percent SEV. The results indicate that approximately 8 min of adequate life support are available in the emergency mode.
