(UL), OSHA, NSI, BOCA, ICBO, SBCCI and the FAA (Commercial airliners have tritium exit signs to protect their passengers). Other approvals/acceptances include: Underwriters Laboratories Inc.

Yes, self luminous tritium exit signs meet the requirements of the NFPA®, Life Safety Code 101® which is the bible for most fire codes. In fact, the brightness of tritium exit signs is more than twice the Underwriters Laboratories (UL) minimum requirement for emergency egress signage. You may not be able to see the light emitted by the tritium tubes during normal lighting conditions, but the UL required contrast ratio of the face colors makes the self luminous exit signs very visible when you really need it, when the power has gone out, the self luminous exit signs become very visible. Your self luminous exit sign is always on just take it into a dark room and turn off the lights to view the illumination.

You do not have to do anything to activate tritium exit signs.

End User Contact Name / Title / Email Address / Fax Number & Phone Number (who has overall responsibility for the sign).

End User Address of Installation (Street, State, Zip-code) (where the sign will be installed).

End User Company Name (for whom/where signs will be installed).

Before an order can be processed for shipment, the following End User (where the tritium exit signs will actually be installed) Information will need to be provided: Self-luminous tritium exit signs are required by law to be registered with the U.S. Why is additional address information required for purchasing tritium exit signs? The electron from the tritium gas has such low energy that it cannot even penetrate an ordinary sheet of paper, and so actually never escapes the sealed glass tube.

That is why self-luminous exit signs are not visible in daylight while TV pictures are. The electron from tritium however has only about 1/4 of the energy of the electron in a color TV picture tube. The process is very similar to that in your television set picture tube where an electron is used to illuminate the front screen of the tube. This illumination is internal, without the need for a source of electrical power, therefore these tritium exit signs are also known as ' self luminous exit signs'' or ' self luminous tritium exit signs.', Basically the electrons of the phosphor coating are excited into emitting electromagnetic radiation in the visible spectrum (i.e. Self luminous tritium exit signs are illuminated via the radioluminescence of the phosphor coating of a glass tube by electrons emitted from a tritium gas.
