How Do You Identify Tritium Exit Signs?
Exit signs provide direction and illumination to help lead people to safety in the event of emergencies. Some exit signs use batteries or photovoltaic cells to power their lights in the event of the loss of power to a building. Some signs use a mix of tritium and a variety of light-producing chemicals to produce illumination. Tritium is a radioactive material, which, as it decays, feeds the chemical reaction that powers the light. Tritium exit signs can be very dangerous to handle–a broken one will release harmful levels of radiation. Learn how to identify a tritium exit sign so you can keep yourself safe when renovating or performing maintenance. Step 1 Locate and open the fuse box for the building.
