HazSight
See the danger. Know what to do. No signal required.
HazSight identifies hazardous-materials placards from a single camera photo and returns plain-language, action-oriented safety guidance from the 2024 Emergency Response Guidebook — running Google's Gemma 4 multimodal model entirely on-device, with zero network calls on the path from photo to guidance.
Debug build — installs outside the Play Store; you may need to allow installs from unknown sources. Requires a physical Android device (6 GB+ RAM) for on-device Gemma 4 inference.
DOT placards, NFPA 704 diamonds, GHS labels, and UN markings. Full ERG guidance resolves from the UN number.
Guidance is delivered in English (the verified primary language). Other languages can be requested and are generated on-device by Gemma 4 — best-effort, not individually verified for safety-critical text.
The model and the full ERG database are on the device. Hazmat incidents rarely happen near reliable coverage.
Every interaction opens with a reminder not to approach hazards and to call 9-1-1. Emergency Mode auto-escalates on detected hazards.
