Timbo,

This suggests a major protocol violation to me. It was my impression that emergency doors were supposed to be opened each day along with the main door (and closed at end of day) to preclude exactly this sort of problem. Or am I being a bit too idealistic/misinformed?

I found a very nice image of an emergency door at 23 Wall Street, NYC. This was constructed by J.P. Morgan. Because of copyright concerns I'll just post the link:

Apparently the hinges were adjusted a tiny bit "high" because of wear marks at the top of the door and receptacle.

The very impressive main door is shown here:

Any thoughts on who manufactured them?
