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 a multimodal model entirely on-device, with zero network calls on the path from photo to guidance.

What HazSight does
What it detects
DOT placards, NFPA 704 diamonds, GHS labels, and UN markings. Full ERG guidance resolves from the UN number.
Language
Guidance is delivered in English (the verified primary language). Other languages can be requested and are generated on-device (best-effort, not individually verified for safety-critical text).
Offline by design
The model and the full ERG database live on the device. Hazmat incidents rarely happen near reliable coverage.
Safety-first
Every interaction opens with a reminder not to approach hazards and to call emergency services. Emergency Mode auto-escalates on detected hazards.
