The OPS supplies the EMU with oxygen purge flow and pressure control for certain failure modes of the PLSS or PGA during EVA.
In the event of a PLSS failure, the OPS flow is regulated to 3.7 +/- 0.3 psid for 30 minutes to provide breathing oxygen to the crewman, to prevent excessive carbon dioxide buildup, and to provide limited cooling.
In the lunar EVA configuration, the OPS is mounted on top of the PLSS. During contingency EV transfer from the lunar module, however, the OPS is attached by straps to the lower front torso of the PGA.
