Re: Do turbolifts have any sense?
The tri-ladder could just be surrounded by a simple revolving mechanism (similar to the revolving wall closet in the cabins). In case of compartment decompression the corresponding deck segment tube just rotates to seal off the area, so you could use the tri-ladder as long as there are compartments unaffected by decompression.
