Frankly, half the stuff in there shouldn't be in there in the first place. It just breeds this sort of non-antag scavenger hunt for goodies. You get Officers who always look for knives and tact masks, janitors who always look for security vests, and random deaths via wormhole jaunter because people think it's a toy. Have other crap spawn in maintenance instead. Decent amounts of metal and glass sheeting, more hazard vests, standard gasmasks, and welding equipment. Full boxes of tools, maglights, ect. Stuff that you'd expect to be in there.
