Grrr... you just reminded me of the horrors of working at the jail...
inventory every tool
run your id on arrival (make sure your tickets are paid before showing up to work, or you'll stay longer than you expected to)
every door locked
10-15 min ordeal to go get a tool you forgot to bring in the first trip because of all the doors
every fastener tamper-proof
no power outlets
no access to anything except in undersize pipe chases
spent an hour with a hammer arrestor up my butt (at least it kept me from falling) wedged in the upper half of a two story chase there a while ago. I'm quitting the cigs (again) and have put on about 10lb. 15 and I'd have never got in, or never got back out.
