The fire started at 7 PM.
The hot work finished at 3 PM.
What can you prove?

Without DutyProof

Your welder finished at 3 PM. Fire watch says he stayed. Nobody verified. Now the fire marshal wants documentation.

You hand them a paper log — handwritten times, no GPS, no proof anyone was there. Claim disputed. Litigation begins.

We asked the trades one question.

“How does fire watch actually work on your jobs?”

A hundred conversations. Same answer. Every time.

One guy with a fire extinguisher paying absolutely no attention to the person doing work. That's fire watch on most of my jobs.

Commercial Construction

We're supposed to stay an hour after hot work but they didn't want to pay us — so we'd leave right after welding.

Documentation says everything was fine. The field reality tells a completely different story. That gap is where people get hurt.

CM
Compliance Manager
Excavation & Utilities

The watch gets treated like a formality. The after-watch window gets shortened because 'it looks fine.' Then something catches three hours later.

CM
Construction Manager
General Contracting

Fire watch is often the same mechanic who needed the welding done — they stick around because they have to finish the job. It's a conflict of interest from the start.

FAQ

Answers before you ask

Contractor plan is $199/month — 10 watches per month, unlimited job sites. Professional is $499/month for unlimited watches. Enterprise pricing available for large operations. No per-user fees, no setup costs. 30-day money-back guarantee.

DutyProof generates GPS-verified, server-timestamped, carrier-confirmed records for every check-in — exactly the kind of documentation OSHA inspectors, fire marshals, and insurance adjusters need when auditing hot work fire watch compliance. Every entry is immutable and write-once. Note: DutyProof supports fire watch documentation workflows; each contractor remains responsible for compliance with OSHA 29 CFR 1910.252, NFPA 51B, and local AHJ requirements.

OSHA 29 CFR 1910.252 and NFPA 51B require a fire watch to be maintained during and for at least 30 minutes after hot work operations. Most contractors run check-ins every 15–30 minutes during that post-work watch period. DutyProof supports any interval you configure — 15, 30, or custom.

Open DutyProof, go to Watch History, find the watch in question, and click Download Report. In under 60 seconds you have a print-ready PDF with every check-in, GPS coordinate, missed check-in alert, and timestamp — more verifiable documentation than any paper log can provide.

Yes. You can run multiple concurrent watches — one per work area, floor, or welding bay — each with its own assigned watcher, check-in interval, and audit trail. All active watches appear on your dashboard sorted by urgency. One subscription covers all active watches at that job site.

Any smartphone with a web browser — no app to download, no login required. Each watch gets one persistent check-in link. The watcher opens it once and the page handles the entire schedule — countdown timer, check-in button, GPS logging. It works fully offline too. Links can be shared via email, optional SMS, QR code, or copied from the dashboard.

DutyProof works offline. If the watcher opened the check-in link before losing signal (basements, parking garages, steel-framed buildings), they can still tap CHECK IN NOW. The check-in is saved to their phone with the device timestamp and GPS coordinates, then syncs automatically to the server the moment connectivity returns. No false misses, no panicked calls to the office. The compliance report shows both the device time and the sync time for a complete audit trail.

DutyProof automatically marks the check-in as missed and alerts your supervisor within 60 seconds — with a tap-to-acknowledge link. Alerts can be delivered via dashboard notification or optional SMS. The supervisor taps the link to confirm they saw the alert, and their acknowledgment is GPS-logged and timestamped. The miss and the response are both permanently recorded in the audit trail. OSHA inspectors see not just that a gap was detected, but that management responded.

Plans start at $199/month. Your records are retained for the life of your account, and compliance reports remain downloadable for 12 months after cancellation.
