    The G1 E BA includes a centralised power module that powers the entire unit from a single battery compartment, and improved voice amplification communications. An additional safety feature of the MSA G1 E BA is the ability to attach, through a buddy breathing line, to other users. The darkness and smoke piercing buddy lights that are incorporated in the power unit provide all users with improved situational awareness.
