Abstract
A detection apparatus for monitoring specified safety eyewear being worn by persons who are either passing into or are located in the designated area which requires that a person in the area be wearing the specified safety eyewear. The detection apparatus includes an infrared reflector which is located on the specified eyewear, an infrared transmitter for transmitting a beam of infrared radiation towards the person, an infrared receiver which receives reflected radiation from the infrared reflector on the safety eyewear being worn by the person and an alarm which is normally inactive and which remains inactive as long as infrared radiation from the transmitter is reflected back to the infrared receiver from the reflector. The alarm is activated when infrared radiation is transmitted to the person and not reflected to the receiver due to the absence of specified safety eyewear which contains the appropriate infrared reflector.
