- GENERAL WARNINGS: General warnings on mobile equipment are not very effective in most work environments. It is well understood and documented that if warnings are given often, even when workers are not in danger, they will soon begin to ignore the warnings.
- MULTIPLE WARNINGS: Whenever multiple vehicle/machines are operating within a work area, general warnings are even less effective. If each of them is issuing audible warnings as they move about, workers must either spend much of their time evaluating the warnings or ignore them. Policies, rules, training and other management approaches have not been able to significantly improve this condition.
Nuisance Alarms and/or false alarms will make a safety system unusable. Most non-magnetic technologies, such as RFID, have not been very effective partly due to frequently sounding alarms when there is no real danger. Multiple machines and multiple systems cause conflicts and confusion in some types of systems.
- BACKING UP: The most common Hit-By accidents occur when vehicles/machines are being driven in reverse. The operator does not have full use of his vision some of the time, especially if managing a load in the front of the truck.
- SOLUTION: HIT-NOT® warns each individual only when that individual is dangerously close to a vehicle/mobile machine. HIT-NOT® also warns individual operators only when a pedestrian with a PAD is close enough to his/her vehicle/ mobile machine to be in danger. Precise safety zones are provided all around the trucks, being longer in the front and rear than on the sides. The pedestrian and the operator will respond to warnings given to them individually when they, individually, are in jeopardy or when they are jeopardizing the safety of a pedestrian.
- A COLLISION AVOIDANCE MODULE (CAM) can be added to HIT-NOT® to enable vehicle to vehicle proximity detection and collision avoidance.
