Abstract:
A heat alert safety device for warning individuals that a surface of an object is hot, comprisinga light source that generates a light beam, a fiber optic cable formed of a plurality of fibers, said fiber optic cable connected at a first end of said fiber optic cable to the light source and oriented so that the plurality of fibers are directly in a path of the light beam, said fiber optic cable transmitting the light beam from the light source beginning from the first end to the second end of said fiber optic cable, the second end of said fiber optic cable shining the light beam out of the cable, a predetermined symbol adjacent the second end of the fiber optic cables, the symbol readily visible only when illuminated to an observer who can also readily see the surface, said symbol communicating that the surface is dangerously hot, a controller controlling the light source so that whenever a specified surface temperature is reached, the symbol is illuminated and remains illuminated as long as said specified surface temperature is maintained, and heat sensor adjacent the surface and connected to the controller for ascertaining a surface temperature and communicating the surface temperature to the controller.
