Detecting PPE and hazard gaps on construction sites

Supervisors cannot watch every zone; missing PPE and unsafe proximity events go unreported until incidents.

Problem

Large sites have blind spots; safety walks sample only a fraction of work fronts.

Safety officers patrol, log observations, and hold toolbox talks after near misses.

Injuries, stop-work orders, and project delays.

Camera analytics can alert supervisors to missing PPE or exclusion-zone breaches for human verification.

Occlusion, privacy of workers, and lighting at night.

Surveillance overreach; biased enforcement; alert fatigue.

More officers and mandatory checklists.

Labor intensive; checklists do not catch real-time behaviors.
