For your safety trip you should know the signs that you may encounter in many places, like airports, hotels and other places. Through this post I want to share information about a very important sign; Exit Sign.
The exit sign is a device in a public service; airports, building, ship, and many more, which appears in the emergency exit. Most of the exit signs from around the world are pictograms with or without additional text. There was a trend towards the adoption of the exit sign in the last ten years. A small minority of countries have exit signs that the word “EXIT” (or the equivalent in another language are joined). His goal is to bring people to the nearest exit in case of fire or other emergency. Most codes require an emergency exit signs are permanently lit.
The exit sign of the first generally made of metal and illuminated by a light bulb or in the vicinity of a glass cover, which respond directly to a single light bulb. The errors inherent in these designs, which have been in a fire, power light not often. In addition, the parties are small and weak, which is difficult to see in a fire, where smoke often reduces visibility. Better signs are from the modern production today as the most developed, with a light bulb in a rectangular box, that the word “EXIT” lights on both sides. Larger than their predecessors in order to solve this version of the exit signal to some problems of visibility.
3 TYPES EXIT SIGNS
Since visibility can be reduced by smoke during a fire or failure of electric lighting, the sign is often permanently illuminated, usually one of the following;
Radioluminescent , self-luminous, where a phosphor layer shines in a glass tube through the beta decay of radioactive tritium into the tube.
Phosphorescence -Glow in the Dark -, afterglow, where the emitted light is absorbed slowly through the area and again.
Current power source with a local battery. Produce electricity, with the lighting circuits to the building emergency power supply from UPS and / or a generator.
