Respirator pack
From Halopedia, the Halo wiki
Respirator Packs are equipment used by the UNSC.[1] Respirators are worn by UNSC personnel when an atmosphere is not present, and provide an auxiliary supply of oxygen to the wearer. Every crewman on a Naval vessel is outfitted with a respirator pack.[1]
The crew of the UNSC Commonwealth were ordered to don respirator packs when Captain Wallace vented atmosphere in the ship to cut off a fire caused by plasma. This was suggested by Doctor Halsey to Captain Wallace, who readily agreed.[1]
