Recall is the fraction of real positives the model actually catches: TP / (TP + FN). For safety-critical workflows like PPE detection, recall trumps precision — a missed unhelmeted worker is a much bigger liability than a false positive an HSE supervisor dismisses. FI Tech tunes operating thresholds to keep recall above 0.95 on hard-hat and harness classes, accepting a few extra false alarms. The cost of a missed violation in oil-and-gas hot work or confined-space entry can run into millions of riyals plus regulatory exposure under Saudi MEWA labor regulations.
