Why not just edit the FLHA when conditions change?

Editing a signed form silently invalidates every signature on it. A revision copies the form into a new numbered version, preserves the original, and re-collects sign-offs so the record matches what the crew agreed to.

What happens to links pointing at the old version?

Superseded forms become read-only and show a banner pointing at the current revision, so QR, email, and task links always land on the version that counts.

Do workers have to sign the revision?

Yes. A revision starts with no signatures and fresh sign-in tasks go out to the crew; signing completes them exactly like a first-time sign-in.

Conditions changed.
Re-issue, re-sign.

When scope changes mid-shift, issue a new revision of the day's FLHA instead of editing a form people already signed. The original stays intact, the crew is asked to review and sign again.

What it does

Editing a signed FLHA silently invalidates every signature on it. Revisions copy the current form — crew, tasks, hazards, controls, permits — into a numbered new version, mark the old one superseded and read-only, and re-collect sign-offs so the record matches what the crew actually agreed to.

Key capabilities

Everything included.

Full revision chain

Every version stays in one chain with its number, status, timestamps, and reason — each openable for the record.

Superseded is read-only

Old links from a QR, email, or task show a banner and point at the version that counts.

Fresh signatures

A revision starts with no signatures. QR sign-in, in-app sign-in, and the daily task all resolve to the active revision.

Reason on the record

The optional revision reason is the field auditors read first — weather turned, new trade arrived, task added.

Flows into the record

PDF email and the audit package use the active revision, with earlier revisions retained.

WorkSkedge integration

How it connects to your operations platform.

Creating a revision dispatches fresh sign-in tasks to the crew's WorkSkedge inbox.
Signing the revision completes those tasks exactly like a first-time sign-in.
