Such a device should be for personal use only and not used as a buddy OOG source. Safe Diving refers directly to this in the following way: Alternate (gas) sources (Air and nitrox diving) BSAC strongly recommends that all divers carry an Alternate (gas) Source (AS) in the event that they may need to share gas underwater.
