eCFR live fallback
When local search returns nothing, tap once to open the live eCFR.gov source — always current.
The step-by-step classification wizard follows 29 CFR 1904.7 general recording criteria to guide you from initial observation to the correct OSHA classification:
Contributing factors are mapped to specific regulation citations so your documentation is immediately actionable. Every assessment is stored in history — no cloud, no sync.
NOAA Rothfusz equation computes heat index from temperature and relative humidity. OSHA threshold indicators: 80°F initial caution (hydration/monitoring) and 90°F high-heat protocol. Instant risk tier output — no internet needed.
Capture incident notes and site observations by voice — no typing required. Speech recognition runs entirely on-device using Apple's on-device framework. Audio never leaves the phone. Works in noisy environments with PPE on.
Attach photos directly to incident assessments. Use PencilKit to circle hazards, add arrows, draw measurements, or write annotations. All markup and photos are stored locally with the assessment record.
When local database search returns nothing, a single tap opens eCFR.gov directly. The live fallback keeps you connected to the authoritative source when regulations are updated between app versions.
The full regulation database ships with the app. No Wi-Fi, no cell signal, no account — OSHA Reference works the same in a basement, tunnel, rural site, or anywhere else you don't have connectivity.
Zero sign-up, zero analytics, zero data collection. Your incident records and search history stay on your device. OSHA Reference never phones home, never sends data to a server.
