SafeSite AI

THE PROBLEM Every 3 minutes a construction worker is injured in the U.S. and every 8 hours one dies. Human supervisors cannot watch every corner of a 5‑acre site; it’s a biological limit, not negligence. Meanwhile traditional AI solutions hallucinate bounding boxes and cause alarm fatigue. OUR SOLUTION SafeSite AI is a dual‑layer safety pipeline purpose‑built for construction sites. The “eyes” of the system are YOLOv8, a fast, local object detector that spots missing hardhats, vests, and harnesses in 1.6 ms per frame with pixel‑perfect bounding boxes and zero hallucination risk. The “brain” is Google Gemini 2.5, which wakes only when YOLO finds a potential violation. A Vision Agent confirms the threat; a Regulation Agent pulls the verbatim OSHA standard from an 800‑page PDF loaded in context; and an Alert Agent drafts a structured, legally‑grounded supervisor notification. Crucially, no alarm sounds until Gemini has verified the danger—giving the supervisor a yellow “checking” card first, then a red verified alert with the exact OSHA code and penalty, while the worker receives an instant polite audio reminder. TECHNICAL HIGHLIGHTS • YOLOv8 + Roboflow PPE model – 1.6 ms per frame, 30+ FPS, local inference • Gemini 2.5 Flash (vision confirmation), Pro (OSHA grounding), Flash‑Lite (alert formatting) • Python FastAPI async backend with WebSocket push to a React dashboard • SQLite audit log records every detection, verification, and human acknowledgment • Human‑in‑the‑loop approval – the supervisor always has the final say BUSINESS VALUE SafeSite AI reduces preventable injuries and OSHA fines. Every avoided fall saves an estimated $145 000 in penalties and litigation, while letting supervisors focus on high‑value tasks instead of monitoring screens.
