A hand would certainly be handy.

We're sort of in luck - there's a dead soldier with two perfectly good hands in the laundry room.

We can use the hand on the hand scanner! Hooray!

Of course - just like the detention cell, this hand is too cold for the scanner.

We need to warm it up.

We don't have a microwave, but there might be another machine that makes lots of heat down here.

Something we've already interacted with.

Use the drilling machine's lever to switch it on, then warm up the hand with the steam it releases.

The warm hand can then be used to open the big door in the main hall.
