Do fire extinguisher signs need to be photoluminescent, or “glow-in-the-dark”?
Again, there are no common rules here that mandate this treatment. On the other hand, fires often cause blackouts. A photoluminescent or reflective sign only increases the chances that vital fire protection equipment, shut-off’s, etc. will be found quickly. Photoluminescent signs glow in the dark after the lights are off. Reflective signs take the light from a flashlight or backup light and return the light in a way that makes the sign evident. Give your emergency crews and other fire fighting teams all the help that they deserve.
