I would still carry a small (ARC-AAA/Photon) flashlight and a whistle on my person. They are unobtrusive and come in handy, especially the flashlight. If the lights go out for any reason, at least you have something immediately available or can use it to search the copier for that elusive sheet of jammed paper. The whistle in addition to alert someone you need assistance, can sometimes also chase away those who might mean you harm. Pete
