An apparatus configured for use with a first power cord, a second power cord and safety glasses including a first wireless communication device. The apparatus includes at least one line conductor, an electrical isolation device configured to prevent current flow in the at least one line conductor, a second wireless communication device configured to wirelessly couple to the first wireless communication device and a body housing the electrical isolation device and the second wireless communication device. The body includes a collar configured to move in a direction parallel to the longitudinal axis while coupled to the body. The collar includes an interior wall that defines a hollow region sized and configured to receive at least a portion of the body therein, the collar configured to secure to one of the female electrical socket and the male electrical plug with the respective one of first power cord and the second power cord electrically coupled to the distal end of the body and the collar at least partially extended from the body in a direction of the distal end. The electrical isolation device is configured to allow current flow in the at least one line conductor when the information provided by the wireless signal indicates that the safety glasses are being worn by the user.
