When I was a Civil engineer with a bridge project that was over a railway, it was required that I take a safety class from BNSF about how to be near the rails, and what not to do. The first thing in the class was that they noted the e,regency exit from the room. (Iirc, the room had one door, to the outside, that we had just walked through to get in the room).
