ABSTRACT:
A box designed for holding safety apparatus, such as face and eye protecting shields used in conjunction with grinders and the like, is electrically wired to such grinder or similar shop equipment. When the face and eye protector is stored within the box, the electrical circuit to the grinder remains open so that it cannot be used. A user of the grinder must first remove the face and eye protector from the box, presumably to use the protector in the prescribed manner, and a spring actuated switch then closes the electrical circuit so that the grinder may be operated.
