I would like to propose a way to fight fires, rescue people and make repairs aboard a starship. I call this system the rescue chute system (RCS). The RCS consists of pipes made from duranium or other extremely hard material, each about 5 meters in length. The ends would be made, so they could fit together, to form even longer pipes or chutes, if needed. Fittings like T-junctions and elbows could also be constructed. Tight fittings would prevent gases and/or fire from getting inside them. Each pipe and fitting could be a meter or so in diameter, to allow people to crawl through them. People could use these chutes to reach people trapped in dangerous areas, to put out fires from up close or to retrieve important documents or objects, without exposing people to the hazardous conditions there. These chutes and fittings could be stored aboard ships and transported to the damaged section of the ship on antigrav sleds. What do you think?
