The most common accidents in warehouses and other industrial workplaces occur when powered vehicles are involved. Particularly, pedestrian safety when working around forklifts often has room for improvement. The HIT-NOT® Proximity Alert Sensor addresses these problems by providing an advanced solution in collision avoidance. When warnings in the workplace occur too frequently, or there are false alarms due to technology limitations, an alert system becomes unusable and ineffective. HIT-NOT® combats this problem by warning everyone only when that individual is dangerously close to a powered vehicle.
