Factory or Warehouse Flooding: How to Keep Business Moving

Updated 28 September 2026 | Guidance for factories, warehouses, importers and exporters

Short answer: When flooding affects a factory or warehouse, prioritize people’s safety, damage containment, evidence collection and shipment deadlines. While water remains high, isolate electrical risks, move high-value goods, document damage and notify customers or suppliers in writing. As the water recedes, wait for the insurance survey, segregate wet stock, check container free time and review every Letter of Credit deadline before restarting operations.

What should a business do first after factory or warehouse flooding?

Create one incident list covering people, inventory, machinery, shipments and documents, then work from the highest-risk and earliest-deadline items. Do not clean or dispose of damaged goods before recording evidence and contacting the insurer, because doing so may affect the claim assessment.

Assign one incident coordinator and classify tasks into three levels:

• Immediate: people, electricity, chemicals, machinery and high-value inventory
• Within 24 hours: insurance evidence, customers, suppliers, forwarders, carriers and urgent orders
• Within 48–72 hours: site recovery, alternative transport and the restart schedule

PHASE 1: Water is still high — contain the damage

1. Put employee safety first

Have the responsible person isolate electricity in exposed zones. Keep employees out of areas where the water is deep or the floor cannot be seen. Secure access around electrical panels, machinery, chemicals and slip hazards. If electrical or structural safety is uncertain, wait for a qualified specialist before re-entry.

2. Move high-value and time-critical goods

Prioritize electronics, moisture-sensitive materials, critical records, small machinery and orders with the nearest delivery date. Use pallets or racking to raise stock above the waterline and record every new location so the inventory can be reconciled later.

3. Create complete photo and video evidence

Capture wide views and close-ups showing the water level, affected areas, pallets, packaging, product labels, model numbers and serial numbers. When possible, record the date, time, location and photographer, then prepare an item count and an estimated value. Keep at least two backups of the evidence.

4. Notify customers and suppliers in writing

If delivery may be late, issue an early written notice stating the affected order or shipment, the cause, the expected impact and the date of the next update. If the contract includes a force majeure clause, follow its notice format and deadline and attach relevant evidence, such as photographs or an official disaster-area announcement. Force majeure relief is not automatic; it depends on the contract and the facts of the case.

PHASE 2: Water is receding — recover and resume

1. Do not discard or clean damaged goods too early

Photograph the goods before moving them, notify the insurer and request a surveyor. If stock must be moved for safety, record the reason, quantity, condition and new location. Where practical, wait for the insurer’s instructions before disposal, repair or cleaning.

2. Segregate wet stock immediately

Create a clearly labelled quarantine area for wet or potentially contaminated goods. Separate them by lot or pallet number to reduce the risk of mould, odour, moisture migration and accidental mixing with saleable stock. Do not return goods to available inventory until they pass the company’s quality-control process.

3. Check port containers and free time

Free time is the period allowed by a carrier or service provider before specified container-use charges begin. Demurrage commonly applies when a container remains at the terminal or another designated facility beyond free time, while detention commonly applies when equipment is kept outside the terminal beyond the permitted period. List every container number, terminal, last free day and owner, then contact the forwarder or carrier immediately to discuss options or an extension. Approval depends on the provider’s terms.

4. Review the L/C latest shipment and expiry dates

For shipments paid under a Letter of Credit, check the Latest Shipment Date, Expiry Date, Presentation Period and required documents. If a deadline may be missed, coordinate with the buyer, bank and other parties to request an amendment before expiry. Do not wait until the shipment date or L/C has already lapsed.

First 24-hour checklist for operations teams

1. Account for employees and restrict access to hazardous zones.
2. Have the responsible person isolate unsafe electrical systems.
3. Move high-value stock and orders with the earliest delivery dates.
4. Photograph water levels, pallets, labels and serial numbers before moving goods.
5. Open one incident list for stock, machinery, orders and shipments.
6. Notify the insurer, customers, suppliers, forwarder and relevant carriers.
7. Check last free day, cut-off, ETD/ETA and all L/C deadlines.
8. Set the next update time and assign an owner to each action.

What information should you give your freight forwarder?

Send a complete information set so alternatives can be assessed quickly: booking or B/L number, container number, origin and destination, cargo status, cut-off, ETD/ETA, last free day, L/C requirements, urgency and the date the site expects to resume receiving or dispatching cargo. If the original route is no longer viable, request a comparison of alternative routes, ports, carriers or transport modes, including estimated cost and transit time.

Transpo Tip: Use one shared table with “item–value–damage status–shipment number–deadline–owner” and sort it by the nearest deadline. Warehouse, finance, sales and logistics teams can then work from the same source of truth.

Frequently asked questions about factory and warehouse flooding

Should a warehouse discard wet goods immediately?

No. Photograph and list the goods first, notify the insurer and wait for the surveyor where practical. If an item must be moved for safety, record its condition, quantity and new location.

What is the difference between demurrage and detention?

Demurrage commonly relates to containers remaining in a terminal or designated facility beyond free time. Detention commonly relates to containers held outside the terminal beyond the permitted period. Definitions and tariffs vary by carrier and trade lane, so check the booking’s quotation or tariff directly.

Does an official disaster declaration always remove late-delivery penalties?

No. Relief depends on the contract wording, the evidence, the causal link to the delay and whether notice was issued on time. Notify the counterparty early and ask legal counsel to review the relevant terms.

What should you do if the L/C latest shipment date is approaching?

Contact the buyer and bank immediately to assess an amendment covering the latest shipment date, expiry date and document presentation period. Request the change before the deadline and confirm that all relevant parties have received the amendment.

When can a factory restart after floodwater recedes?

Restart only after the site, electrical systems, machinery, structure and inventory quality have passed the company’s required safety checks. A lower water level alone is not sufficient clearance.
