How to forbid barrow to all citizens and military?

I want to create barrow for trap corridor, and dont want to any dwarf go into it even to recharge traps.

Solution 1:

You can't easily use a burrow to specifically forbid travel through a certain area, but what you can do is create a burrow that encompasses your entire fort and then assign all of your dwarves to that burrow - by doing this none of your dwarves will leave unless they're starving or dying of thirst.

However, a much easier way to do this would be to simply forbid the traps in question - forbidden objects will not be handled by your dwarves in any way, so the traps won't be reloaded. You can forbid an entire group of objects using the d,b,f keys, which would let you forbid all of the traps in your trap corridor with one action.
