Self-luminous EXIT signs containing the radioactive gas tritium are widely used in a variety of facilities across the United States, such as public and private office buildings, theaters, stores, schools and churches – anywhere the public needs a rapid exit path. Those who possess tritium EXIT signs are general licensees of the Nuclear Regulatory Commission or an Agreement State, and are subject to certain reporting and handling requirements, including proper disposal of unwanted or unused signs. Tritium EXIT signs pose little or no threat to public health and safety and do not constitute a security risk.” — United States Nuclear Regulatory Commission, Fact Sheet on Tritium EXIT signs

Are Tritium Exit Signs bright enough?

While tritium lamps are not visible when normal lighting is on in a building, the UL 924 required contrast ration of the face color makes the exit sign very visible when the normal lighting is off. In fact, the brightness of a Tritium Exit sign is over double the minimum requirement set by UL 924.

Are Tritium Exit Signs UL 924 approved?

Yes, all tritium exit signs sold by The Exit Light Company have a UL 924 listing for exit signs.

Which types of installations are ideal for Tritium Exit Signs?

Tritium is a perfect choice when: there is not enough ambient light to charge a photoluminescent sign; there is no electrical power supply to the location; environments where electricity could ignite particles in the environment; where zero power consumption and no maintenance cost is desired.
