How it works
You never open the app to log a call. OHPAH does it from the moment the tones drop — and turns a career of calls into one record that belongs to you.
The loop
Dispatch drops the tones. OHPAH reads the incident from the dispatch feed — talkgroup, timestamps, and the MPDS severity code, Alpha through Echo — and auto-logs the call. No form. No typing. It happens whether or not you ever open the app.
The clock starts when you arrive at a fire incident and stops when you clear. That on-scene time accumulates into your Fire Exposure Score — the cumulative measure tied to firefighter carcinogen-exposure research.
With your permission, OHPAH reads the biometrics your Apple Watch already records around each call and merges them onto the same timeline. One record — not a call log in one app and a health app somewhere else.
FES, WII, and SDI recompute after every incident — per call, per shift, and across a career. The math runs server-side, so the numbers are consistent no matter which device you open.
Each morning, a single Pass Down briefing summarizes the shift: calls run, on-scene exposure added, sleep lost inside the 2200–0600 window. The record you never had to sit down and write.
What the loop produces
FES
Cumulative on-scene time at fire incidents. Tied to carcinogen exposure research. The number your department has never tracked. Now yours to own.
WII
Physical and operational load per call. Derived from MPDS dispatch severity codes ranging from Alpha through Echo.
SDI
Sleep time lost during the 2200 to 0600 window. Calculated from every dispatch timestamp. Shift by shift. Across a career.
The paperwork you never do is the record you always have.
