Our center manager set up a safety demonstration for us as we came to work this morning. He parked an empty package car directly in front of the employee entrance, drivers side toward the building. He put cones on both sides of the walkway between the PC door and the employee door (less than 5'). He then put a hand printed sign above the passenger door that read "Enter Here" and a 2nd hand printed sign above the driver door in the cab which read "Use Hand Rail As 3rd Point of Contact". He wanted every employee to go through the PC on their way in to the bldg. I can see the point that he was trying to get across but this was not the way to do it. It was a very unsafe demonstration as the PC was blocking a means of egress during an emergency. Our assistant BA happened to be there and he took pictures of the setup. I don't think a single driver went through the PC, including me. Our safety person was quick to point out that she had nothing to do with the demonstration.
