Why Self-Powered Exit Signs?

Self-Powered Exit Signs are the most reliable exit signs produced today. Self-Powered Exit Signs require no external power source, no electrical wiring or batteries to replace and are always ready to provide an effective, maintenance-free exit system. Self-Powered Exit Signs will provide a luminescent sign under any condition, even during an extended period of power outage.

www.self-poweredexitsigns.com offers Self-Powered Exit Signs with a ten and twenty year life-span at a fraction of the cost of most other brands. Compare our prices with any competitor!

What is Tritium?
From the EPA's (Environmental Protection Agency) website:

"Tritium (chemical symbol H-3) is a Self-Powered isotope of the element hydrogen (chemical symbol H). Tritium is produced naturally in the upper atmosphere when cosmic rays strike air molecules. Tritium is also produced as a byproduct in reactors producing electricity, and in special production reactors, where the isotope lithium-6 is bombarded to produce tritium. Tritium occurs naturally in the environment in very low concentrations. Most tritium in the environment is in the form of tritiated water, which easily disburses in the atmosphere, water bodies, soil, and rock. People are exposed to small amounts of tritium every day, since it is widely dispersed in the environment and in the food chain.

Tritium is produced commercially in reactors. It is used in various self-luminescent devices, such as exit signs in buildings, aircraft dials, gauges, luminous paints, and wristwatches. Tritium is also used in life science research, and in studies investigating the safety of potential new drugs.

Tritium is one of the least dangerous radionuclides because it emits very weak radiation and leaves the body relatively quickly."

Because Tritium is safe it has replaced radium (which has been banned for use in the United States as a hazardous substance) for a luminescent source in watches and gauges.
