Triaging Hazard Information Under Uncertainty
A working procedure for deciding what to act on when reports conflict: establishing provenance, checking timestamps, and distinguishing an absence of information from an all-clear.

Learning objectives
- Trace a hazard claim back to its issuing authority or establish that it has none.
- Explain why a timestamp and an issuance channel matter more than the wording of a claim.
- Distinguish no information from an all-clear.
- Act proportionately on an unverified report without either dismissing or amplifying it.
In the field
Ordered, and meant to be workable under pressure. Numbered because the sequence matters.
- Before acting or resharing, find the original issuing authority for the claim.
- Check the timestamp and discard anything superseded by a later official bulletin.
- Treat screenshots as unverified until located on the issuer’s own channel.
- Take precautionary action that is cheap to reverse while verification is still pending.
- Say plainly that something is unconfirmed when you pass it on, rather than dropping the caveat.

The tag under each source states what was actually checked. “Authority named · URL not re-resolved” means the issuing body and document are named, but the link was not re-resolved for this lesson. It is not a claim of verification, and the authority’s own current bulletin always supersedes anything here.
