The Fire Exit Sign - A Tool For Easier Exit Location

Fire exit sign is a tool in an unlimited capacity that shows where the fire exit is. This type of sign with the word "EXIT" is usually in red or green color. An elegant symbol of fire exit is simply observed if visibility is reduced. Currently, emergency lighting is placed on the panel.

Most exit signs around the world are shaped representation, using, or without adding text. Its function is to direct people to the nearest exit when there is fire or other disaster related. Exit is an English word that comes straight from the Latin word meaning "out". As visibility can be reduced in a fire due to smoke or breakdown of electric lighting, the sign is illuminated and often lasting, mostly by self-luminous material, where a phosphor coating inside a glass tube fire due to beta decay. Some are photoluminescent, where light is absorbed from the surroundings and gradually re-produced while others function as the electric light, thanks to a rechargeable power source limited.

In the early days, exit signs are usually made of metal and illuminated by an incandescent bulb. The fabric was little and not shiny, which makes them difficult to see where a fire burning in general decreases visibility. As before, the improved signs were developed to resemble the output current sign today, in which the bulb is placed inside the box and backlits the word "EXIT" on both sides. And hence the upgrade edition of the Output panel responded to the problem of visibility. However, the main power must remain on so that the sign can be useful.

The majority of fire exit signs, excluding countries like the United States, Australia and Singapore are of pictogram style. Some countries including the U.S., especially in New York has approved new policies relating to tall buildings to get the glow in the dark signs with a pictogram. Recently, exit signs in commercial buildings, hospitals and department stores that meet fire code requirements can be noticed, each way for an exit. There are some situations that owns the building further away can not be responsible for several of these codes. On the other hand, the owner of the structure usually meets the terms for exit signs.

Battery backup systems are the typical method to comply with modern building codes require that exit signs should be permanently lit. Today, exit signs use less energy. Different manufacturers have re capacitor banks. Because what makes the invention environmentally friendly as it holds only electronic products conservative. This reduces the regular changing of the battery life since the capacitor is equal to the duration LED.

Exit signs of self-luminous does not need external power source because they only use a device similar to fluorescent lighting. As a substitute of an electric current supplied tritium they use, which are classified in the end up to 2 decades.

Mostly areas such as Japan, Korea, China and Australia use exit signs green as they provide the way forward in an emergency. In Virginia, output signals must be red, while in Maryland they must be green. This difference in the color designation is due to country-code construction that identify approving the color scheme of sign.
