We all rely on signs to help us navigate in unfamiliar surroundings. Anyone disembarking from an airplane outside of their home base needs the guidance of signage to find the baggage claim and ground transportation. Imagine trying to take a hike in the woods without a properly blazed trail. The well-known song might opine that signs are everywhere and are blocking out the scenery, but signs are undeniably useful given the right set of circumstances. This is especially true when one considers firestopping.
