Marking and Indicating Means for Emergency Personnel

Story Behind the Invention

Inventor John David Schumacher of Sergeant Bluff, IA has created a self-illuminating plastic safety pen, which is to be used for marking structures during search and rescue operations.

One of the most critical tasks that firemen perform during a structure fire is that of checking the structure for occupants. However, mistakes may occur due to the unfamiliar environment and the stress of the situation. Often during a routine check, rooms may be omitted or even checked twice. Usually, each room is marked using a marker or spray paint, but these types of indicators are difficult to see in low light conditions. Inventor Schumacher has developed a means by which emergency personnel can easily mark objects and materials so that they remain visible in low or no light conditions.

This clever new invention is used by bending and shaking the cylindrical container, which creates a chemical reaction that produces a self-illuminating ink. The container is then squeezed to release the ink onto the wide-tip applicator. The ink will glow up to twelve hours once released. The invention is ideal for firefighters, who would use the indicator to mark checked areas after a structure fire. The use of the Marking and Indicating Means for Emergency Personnel provides the ability to mark any surface and have it be seen by others in inferior light situations.
