A warehouse reduces false alarms from collision avoidance technology by shaping detection to real traffic and reviewing alert data during a calibration period. Draw zones that follow aisles and travel direction instead of a single circle around the truck, so a person walking safely beside the lane does not trigger an alert. Use tiered distances, a caution level and then a stop-level warning, rather than one alarm radius. Prefer detection that tells people apart from objects. Exclude areas such as charging bays where close proximity is expected, and log every alert so operators can flag the ones they judge invalid.
The full guide is forklift alarm fatigue. Alarms that fire constantly train operators and pedestrians to ignore them, which can leave a site with more risk than before installation. Plan a calibration period of several weeks after go-live, review alerts by zone and shift, and adjust zone shapes, speeds and sensitivity together. Involve operators in the review, since they know which alerts are noise. Record every change so tuning does not quietly remove coverage where it is needed. Zone-based proximity warning systems explains how zones are drawn.
