Warehouses with heavy pedestrian traffic need a system that detects people whether or not they wear a tag, reduces truck speed by zone on compatible forklifts, and controls the intersections where foot and truck routes cross. A warning light on the truck alone is not enough in dense traffic, because pedestrians and drivers stop noticing it. Most high-traffic sites combine on-truck detection with fixed signals at crossings and physical separation such as barriers and marked walkways. OSHA 1910.178 does not require detection systems; it requires safe operation, so the technology sits on top of layout, rules and training.
The full guide is Warehouse pedestrian safety, which starts with separation, because a walkway that keeps people out of truck aisles removes exposure no sensor can fully manage. Then match technology to traffic. Camera detection that recognises people covers visitors and temporary staff without tags; tag-based ranging works around corners and through racking where cameras cannot see; fixed sensors at blind intersections warn people on foot before a truck appears. Suppliers of each type are listed in the vendor comparison and the directory. Ask any supplier for a pilot in your busiest zone and measure false alerts as well as detections.
