ABSTRACT:
Heat alert safety device for warning individuals that a surface is hot wherein a fiber optic cable runs from an electric light source to a heat warning symbol. The cable has a plurality of fibers connected at a first end thereof to the light source and transmits light from the light source beginning from the first end to the second end of the cable and shines light out of the second end of the cable to a predetermined symbol adjacent the second end of the cable. The symbol is readily visible when illuminated to an observer who can also readily see the surface and the symbol communicates that the surface of the stove, in particular, the heating element, is dangerously hot. A controller controls the light source Whenever a specified surface temperature is reached, the symbol is lit and remains lit as long as said specified surface temperature is maintained.
