The Emergency Exit Sign – Applications and Considerations

Signs that feature the word “EXIT” on them are known as emergency exit signs and are used to guide the occupants out of an airplane, boat, or building to safety during a fire or some type of natural disaster.  Where commercial, industrial, and office buildings are concerned, government building and fire codes require that these types of signs be mounted in such a way that individuals will see them and find their way out of the structure.

The technology of these types of signs has evolved during their history in order to extend the lifespan of these products while improving their efficiency at the same time.  There are numerous types of emergency exit signs available on the market today which oftentimes makes the decision of which type to purchase and install quite a challenge.  In order to make the proper decision on the type of sign that is right for you, the accessibility to the power source, application environment, and product cost must be taken into consideration.



The most cost-effective types of emergency exit signs are the LED (Light Emitting Diode) types where the power source is available for an indoor application.  These normally use from two to four watts of electricity and have an 8 to 10-year lifespan.  Where durability is concerned, cast aluminum construction is preferred and can be purchased in black, brushed aluminum, or white housings.  For a more high-end type of indoor application, the edge lit type is preferred by architects, building managers, and lighting designers.

Edge lit emergency exit signs are typically manufactured in both the recessed and the surface-mounted and contains an internal, energy-efficient LED light strip.  This light strip creates a powerful illumination source to a high-grade, screen-printed acrylic panel containing the word “EXIT” on it.  Multiple housing colors are available and can easily be customized with that language and wording that they require.

When you are dealing with an application where there is not an electrical power source available, you can purchase and install a non-electrical type of emergency exit sign such as a photoluminescent model.  These employ a more eco-friendly and glow-in-the-dark, type of industrial-grade pigment to provide a reliable form of illumination to the exit face.  The self-luminous type of emergency exit signs is the most universally applicable type available on the market today and can be used for indoor and outdoor requirements.
