I've been with the federal prison system for 10 yrs. and agree with what everyone else has said. These comments pertain to where I work, and may or may not help you. Each person you have going inside the fence with you, will have to have a N.C.I.C. background check done beforehand. Anyone with a past record will not be going in. Make sure you all have your picture ID with you. Evey tool will be itemized on a tool inventory sheet. If you have tools and tool boxes, they are inventoried and enter/leave through the rear drive in gate. This gate is only open during the dayshift, 7:30 to 3:30. The inmates are not allowed to converse with you, or you with them. If an inmate approaches your work area, the officer should tell the inmate to leave. Our fixtures open with different size torx bits, and some with a #2 security phillips bit with a hole in the center, and some with the security allen with the hole in the center. And as said already, you'll have some that will strip out. I always keep extra screws and cage nuts on hand. We have many different styles of fixtures here. Some are better than others. If you're lucky, you'll have an escort that will have access to the mechanical rooms and breaker panels. Not everyone has access to these areas.
