Where should exit/emergency signs be located?

Fire safety and building codes, such as the NFPA 101 Life Safety Code, mandate the placement of illuminated signs at all designated emergency exits. To ensure occupants can find the exits from any location, especially in complex layouts, directional signs (e.g., with arrows) must be placed along the entire egress path. This creates an unambiguous route to safety during an emergency. These requirements are a matter of legal compliance and personnel safety, not optional data center policy.

A: Data center policies must conform to legally mandated fire and life safety codes; they cannot override them. C: Emergency egress routes and signage are required for the entire facility, including offices and plant rooms, not just the computer room. D: Signs are required only at designated emergency exits and along the path to them, not at every single door (e.g., closets, non-exit offices).
