Hazard detection app: the scanner is the phone already in your pocket

A hazard detection app turns a phone camera into a safety scanner: photograph a work area and AI identifies the visible hazards — a ladder set on bad footing, a damaged cord, a blocked path — each referenced to the OSHA standard it may relate to, with a suggested fix, a confidence level, and a 0-100 area score. OSHA Scan runs entirely in the phone's browser: nothing to install, no app store, no IT ticket — open the page, take or upload a photo, get findings in seconds. Free to try with no account. A person verifies findings on site before they become the record.

The app-store model fits tools you use daily and configure deeply. Field safety scanning is the opposite pattern: intermittent, urgent, and spread across people who never installed anything — the sub's foreman, the new hire, the client rep who spotted something. A browser-based scanner meets that pattern: anyone with the link can scan in the next sixty seconds. There is no version drift between team members, no 'it needs to update first,' no storage-full failure at the worst moment. iOS and Android both hand the camera to the browser natively, so 'take photo' works exactly as it would in a native app.

The trade-offs are honest ones: a browser app needs connectivity to run its analysis — there is no offline scanning — and it does not live on the home screen unless you add it there (both platforms allow it in two taps). For a tool whose job is 'photograph, analyze, assign the fix,' those trade-offs buy the thing that matters more: zero-friction access for every person who might ever need to scan.

Modern phone cameras produce more than enough detail for hazard analysis: cord damage, ladder angles, missing guards, and PPE presence all read clearly from a normal working distance. What matters more than megapixels is framing — the analysis reads relationships, so the useful photo contains both the hazard and its context: the ladder AND its footing, the cord AND the walkway it crosses, the worker AND the edge behind them. One photo per work area, taken from where a person would actually stand, out-performs a dozen zoomed close-ups.

The camera's limits are the analysis's limits. A photo cannot convey noise, atmosphere, energy state, weight, or what is behind the wall — and OSHA Scan does not pretend otherwise: findings are phrased as 'possibly related to' a standard, carry confidence levels, and the report structure assumes a person walks the floor to verify. The app's job is to make the visible half of hazard detection nearly instant, so the human half gets the time it deserves.

The compounding value of an app-based scanner arrives when it stops being one person's tool. Because every scan saves to the same organization — with locations, roles, and per-area history — the superintendent's Monday scan, the foreman's delivery-day scan, and the safety manager's audit scan all feed one record. Corrective actions get owners across the team, scores build per-location trend lines, and the PDF export for the GC or the insurer draws from everything, not just what one phone captured. The rollout playbook is short: send the link, set a cadence (each area, weekly, plus every changed condition), and route findings to owners the same day. The phones were already on site; the program was the missing piece.

• Put the link where the team already looks
• Add it to the home screen
• Frame the hazard with its context
• Scan one area per photo
