Photoluminescent (Glow in the Dark) Signs

Photoluminescent or self-luminous (radioluminescent) Signs are SABS Approved safety signs that emits light as the result of the absorption of radiation, and that continues for a noticeable length of time after excitation. These signs provide information for fire prevention, fire-fighting equipment, emergency escape routes and the location thereof.

These symbolic safety signs display a *white or red pictogram on a green or white square shaped sign, surrounded by a red border (in the case of a red pictogram). Some examples of such signs are those that indicate where fire hoses and hydrants are located.

*(radioluminescent green or radioluminescent red and photoluminescent white, respectively, shall be used instead of white.)

The height, width or diameter of the pictogram on these signs occupy between 75 % and 90 % of the corresponding dimensions of the backing sheet, either Chromadek Steel or ABS Plastic.

SABS approved sizes for safety signs are 150x150mm, 190x190mm, 290x290mm, 440x440mm and 880x880mm. It is however uneconomical to print 150x150mm so the industry by large has adopted printing 190x190mm and up.
