Per the code commentary, the intent of section 703.7 is to let tradesmen working in the building after initial construction know that a particular wall is fire rated construction, so that any penetrations they make in the fire rated assembly are protected accordingly. But why does this only come into play in concealed spaces? If you have a room with no ceilings and fire rated walls going to deck above, why shouldn’t those walls also be identified as being fire rated?
703.7 Marking and identification.
Where there is an accessible concealed floor, floor-ceiling or attic space, fire walls, fire barriers, fire partitions, smoke barriers and smoke partitions or any other wall required to have protected openings or penetrations shall be effectively and permanently identified with signs or stenciling in the concealed space. Such identification shall:
1. Be located within 15 feet (4572 mm) of the end of each wall and at intervals not exceeding 30 feet (9144 mm) measured horizontally along the wall or partition.
2. Include lettering not less than 3 inches (76 mm) in height with a minimum 3/8-inch (9.5 mm) stroke in a contrasting color incorporating the suggested wording, “FIRE AND/OR SMOKE BARRIER—PROTECT ALL OPENINGS,” or other wording.
