Fire & Flooding Affecting DP Systems

Topic: DP Emergencies · Sub-topic: Fire/Flooding  ·  Level: DPO / Senior DPO  ·  Read time: 9 min

1. What / Why / How

A fire or flooding event in a space housing DP-relevant equipment is a genuine dual emergency: a life-safety event in its own right, and a potential DP capability event, since firefighting actions themselves (space isolation, de-energising circuits) can remove DP-relevant equipment from service. The DPO's assessment has to track both dimensions together.

2. Recognition / Risk / But

DP capability may be actively changing as the emergency response unfolds — an isolation action taken for firefighting reasons can remove exactly the equipment DP capability depends on. But: don't assume DP capability is unaffected just because no DP alarm has activated yet — actively cross-check with the bridge team/emergency coordinator about which spaces and systems are affected.

3. Now / What next / Decision / Why

If a generator's switchboard room is being isolated as a precaution, before the generator itself trips, treat that as a strong leading indicator and proactively prepare the operational response — don't wait for the trip itself.

4. Consequence / Reassess / Escalate

During a genuine dual emergency, DP-relevant consequences can develop faster than in an isolated equipment fault. A DPO who waits for the DP system to reflect a consequence that firefighting information already predicted accepts an avoidable delay.

5. Recover / Verify / Human factor

The fire being declared out is not itself confirmation DP capability is restored. Verify the specific equipment that was isolated is functionally restored and validated — a space being safe to re-enter doesn't mean every piece of equipment in it survived undamaged. Trap: treating the firefighting all-clear as a DP all-clear.
