Scramble mode! Who has a straight or safety pin at the station? As it turns out, no one!
I ran to the shop where Dave, one of our maintenance techs, was working on a piece of equipment. With a pair of diagonal cutters and a paperclip we fashioned as temporary fastener. It’s good to work with people who are handy.
Hopefully the clip will last through the night. Gratefully I don’t have to go through any metal detectors this evening.
