Exit Signs: Useful Facts

This is a problem area for me (and likely, many designers) as it is typically done by a registered architect. However, designers should have a knowledge of exit sign symbols, locations, and regulations as it affects the safety and well-being of those occupying a given space. It also determines location of sprinklers, lighting, and other systems components. 

Note: while I would be capable of laying out a life-safety plan (even as a licensed designer), I would always have a registered architect review, approve, and alter (as fit) my layout. 

Some helpful facts

- All exit signs with a directional indicator must be placed in every location where the direction of travel to reach the nearest exit is not apparent. [NFPA 101, Section 7.10.2] 
- At each door providing access to the area of refuge
- At all exits providing an accessible mean of egress
- Where necessary to indicate clearly the direction to an area of refuge
- All doors opening to corridors, to an exit, to an exit passageway
- Within Exit Stairs, horizontal extensions in exit stairs

- There MUST be an audio/visual fire signal device located in each restroom, hallway, lobby, and general assembly area. Also, MUST be visible from any location in the room or space and MUST be mounted between 6’-8” to 7’-6" AFF. 
- The minimum number of fire extinguishers MUST be calculated based on one (1) fire extinguisher per 3000 SF
- Fire extinguishers MUST be located no more than 75’ from the furthest occupant. 
- Smoke and Heat Detector coverage MUST include all rooms, corridors and storage areas.
