A safeguarding technique that provides a means of continually sensing or detecting an individual within an area adjacent to or associated with a hazard. In area guarding, the sensing field is horizontal (or less than 30°) to the floor. Instead of looking for a finger or hand, this application is meant to detect a foot, ankle, thigh, hip or waist, depending on the minimum object sensitivity of the safeguarding device and the mounting height. Choose safety light screens, area scanners, or safety mats. The edge of the sensing field of the area guarding device is the point of detection of an intrusion, and usually must be placed a large distance from the hazard because of the possibility of reach-over hazard. Often, the horizontal sensing field of an area guard is located behind other safeguards. These other safeguards are used as the primary safeguard, responsible for stopping or removing the hazard while the area guarding device is used to prevent start or restart.
