The vacc suit ready rack between the airlock iris valve and the module lower deck cargo door holds four Asiranedii Vactech VSD Heavy-Duty Vacc Suits. The GTL12 vacc suits are a one size fits most design which uses mechanical counterpressure extremities with subpressure supported torso construction.
Each vacc suit consists of a one piece suit which is made up of an inner suit which provides counterpressure support and temperature regulation to the user. The outer skin is made of a tough protective fabric which provides radiation protection and abrasion protection. This fabric includes an outer cameo layer which can be used for camouflage, but is most often used to tag individuals for identification by making the suit a unique brightly visible color. The inner and outer suits are laminated together and may be treated as a single unit. It takes about one minute for an experienced spacer to put on a vacc suit.
A waste relief system allows for extended wear. The suit is self sealing against most small punctures. Patches, normally carried in one of the pockets can be used for larger punctures.
The VSD Vacc Suit has been modified to work with the GP Multipurpose Rigid Helmet. The helmet is provided with a heads up display (HUD). A water reservoir holding one quart of liquid and a concentrated food system is included. The helmet contains a 15 minute reserve tank and a rebreather unit, which extends the tank to 150 minutes. A C cell powers the helmet systems when no Life Support Pack (LSP) is being used. The helmet also contains a short range communicator (10 miles) and a computer. A sensor visor with video pickup allows for recording or transmitting. The helmet also contains an integrated multi-spectrum flashlight. The helmet can also be used with a hazardous atmosphere HILO rebreather/filter assembly unit in atmospheres which do not require a pressure suit and with a standard skin suit.
The Life Support Pack provides heat, cooling and energy for long term suit use and extends the vacc suits ability to function in extreme environments. The LSP contains a 10 lbs air tank with a rebreather which extends the useful life to 20 hours. It also contains a reactionless thruster to allow flight, though it is typically used in space. The LSP is powered by a pair of C cells. The LSP harness contains two lifeline hook D-rings.
The suit gloves are counterpressure designs intended to maximize user dexterity. Each boot contains a grav plate to allow the user to walk along the outer hull of a vessel in microgravity. Each plate is powered by an A cell or the LSP if installed. They are not designed to operate in a gravity field.
