Capture a Defensible First Record
What you will learn
Create a time-linked first record that separates observed facts, reported information, immediate controls, notifications and unresolved questions.
A useful incident record is a trace of what was known and done at each time, not a polished story written after everyone has agreed on an explanation.
Start only after urgent rescue, medical, pollution-control and vessel-safety actions are under way. Record the vessel or operation, date and time with the time standard, position or location and its source, people and roles, conditions, the sequence observed, injury or damage, immediate controls, communications and the current operational state. Identify the author and the time each entry was made. A later reader should be able to distinguish the event time from the note time.
Separate four evidence states. An observation is what the recorder directly saw, heard or measured. A report is attributed to the person who supplied it. An inference is a provisional interpretation. An unknown is left visibly unresolved. Write ‘deckhand reported a snap at 14:07’ rather than converting that report into ‘the shackle failed at 14:07’. Exactness about source and uncertainty is stronger than false precision.
MGN 564 Amendment 2 lists core notification data such as vessel identity, event time and position, people killed or seriously injured, a brief event account, damage, environmental harm and route details where relevant. Its statutory list does not make every internal report identical, and this lesson cannot determine what a live operator, authority, insurer, harbour or legal process requires. Use the current controlled forms and preserve the fuller evidence trail.
Incident-evidence and reporting drill
Build a trace another professional can use
Select a constructed case and follow immediate control, factual record, preservation, classification, parallel routes and owned follow-up. The board teaches questions and boundaries; it does not classify or investigate a real event.
Passenger fall
A passenger falls beside the cockpit. A wet patch is visible, another passenger reports a loose bag strap and the injured person's condition is still developing.
- 1Control now
- 2Record facts
- 3Preserve evidence
- 4Classify carefully
- 5Route in parallel
- 6Own and verify
- Control now
- Protect the person, stabilise the vessel and remove immediate exposure without waiting for the form
- Record facts
- Fix event and note times, location, vessel state, direct observations, attributed reports, casualty state and actions
- Preserve evidence
- Control the deck area, bag, photographs, CCTV or electronic records and record every unavoidable change
- Classify carefully
- Keep operational connection, injury severity and reportability open; do not turn the wet patch or witness report into final cause
- Route in parallel
- Check current MAIB, emergency, operator, employer, harbour, insurer and other routes separately as applicable
- Own and verify
- Track the casualty, evidence, corrections, acknowledgements, controls and any later classification change by named owner
Supported next state
The first record remains usable even if injury severity or the eventual explanation changes.
Authority boundary
This case cannot diagnose the injury, determine operational connection, classify the event or select a real reporting route.
Constructed revision cases only; the board cannot classify a real event, determine a legal duty or deadline, investigate an occurrence or authorise an operational decision.
Worked example
At 14:05 a passenger falls beside the cockpit. The vessel is rolling, a wet patch is visible and another passenger says the person caught a loose bag strap. The injured person is assessed while the skipper alters course for a steadier platform.
- 114:05 event time: record the fall location, vessel state and direct observations without choosing a cause.
- 214:06 control: record the course change, first-aid response, person leading it and present condition.
- 314:07 attributed report: name the witness and preserve their words separately from the wet-patch observation.
- 414:10 evidence state: identify photographs, CCTV or instrument data, the bag and deck area, with custody and access controlled.
- 5Keep severity, operational connection and reporting-route decisions open until the competent current process resolves them.
Sense check: The record can remain accurate even if the eventual explanation changes, because observation, report and inference were never merged.
| Record field | Useful evidence | Weak substitute |
|---|---|---|
| Time | Event time, note time and time standard | ‘Earlier’ |
| Position | Method, source, datum or named location | Unsupported exact coordinate |
| Source | Observed by, reported by or measured by | Anonymous certainty |
| Action | What, when, by whom and current result | ‘Dealt with’ |
| Unknown | Named gap and owner for resolution | A guess inserted as fact |
Build the first ten-minute trace
A line parts during berthing and a crew member reports wrist pain. The vessel is controlled, but several people offer different explanations.
1. Protect
Make people and vessel safe and record the immediate controls without delaying them for paperwork.
2. Anchor
Fix event time, location, people, conditions and the present vessel and casualty state.
3. Separate
Keep direct observations, attributed reports, inferences and unknowns visibly distinct.
4. Own
Name evidence, notification and follow-up owners rather than writing ‘to be reviewed’.
Sense check: A shorter source-labelled record is more defensible than a detailed account that silently converts recollection into fact.
Common mistake or limitation
- Writing one blame-led narrative after the event instead of preserving what was known at each time.
- Using an exact time or position without recording its source or time standard.
- Treating a witness report, instrument output or photograph as self-explanatory rather than identifying source and status.
- Letting the form delay rescue, hazard control or urgent notification.
Recap
- Record event time, note time, location source, people, conditions, sequence, effects, controls and notifications.
- Label observations, attributed reports, inferences and unknowns.
- Keep the current vessel, casualty and evidence state visible.
- Use the real controlled form and reporting route; this lesson does not decide a live duty.
