Every experienced spacer has this emergency device somewhere close by at all times. The vacuum mask is a soft, clear plastic shield that fits over the ears, eyes, nose, and mouth. It can be donned is a move action to protect the user from decompression. A small control unit worn on the belt, sleeve, or chest contain an oxygen candle that refreshes the user’s air supply for up to 8 hours. The mask and control unit stow easily into a packet about the size of a paperback book.

Combined with a spacer’s jumpsuit, the vacuum mask offers complete protection in P0, P1, P2, and P4 conditions for as long as the oxygen holds out.
