I just had a director ask about the necessity for every room having signage in a small existing hotel we have property. It's a 2 story/38 room hotel with every room's door opening directly to the outside path to egress. You have a choice of going right or left....common sense would dictate which way to go based on where the fire is.
I let them know, common sense or not, we are required to provide the exit/evacuation signs in every room. I am in the state of Florida and included the following from the current Florida Fire Prevention Code (NFPA 1 and NFPA 101 with FL specific additions to the base code):
A floor diagram reflecting the actual floor arrangement, exit locations, and room identification shall be posted in a location and manner acceptable to the authority having jurisdiction on, or immediately adjacent to, every guest room door in hotels and in every resident room in dormitories.
I like to throw these things out here to see if it could help others, or if I was way off!
