Quick answer
Prepare an emergency plan that tells staff when to stop work, hold food, seek help and restart safely. Cover utilities and controls the food process depends on, including safe water, refrigeration, cooking, cleaning and staff availability. Keep current contacts, verified alternative arrangements and decision records. An emergency does not suspend food-safety limits, and restored power alone does not prove the affected food or process is safe.
A useful plan supports decisions during disruption
A failure may remove several controls at once. Loss of power can affect refrigeration, lighting, cooking, monitoring and safe access; loss of water affects more than ingredients.
Food-safety management guidance supports identifying hazards and corrective action. Include the failure scenarios in the actual HACCP method and staff instruction.
Write decisions for realistic failures
| Failure | Plan before it happens |
|---|---|
| Unsafe/no water | Stop affected work, supplier/authority contacts and essential facility assessment. |
| Refrigeration/power | Protect stock, credible history/checks, suitable alternative capacity and disposition. |
| Cooking/process equipment | Stop release, identify affected batches and use supported deviation decisions. |
| Drainage/contamination | Stop affected work, segregate food and obtain competent help. |
| Staff/supplier disruption | Limit/change operation only within safe trained capacity. |
| Fire/flood | People first, affected areas/stock out of use and competent recovery. |
| Restart | Required checks, authority conditions and recorded release. |
Check contacts and proposed alternatives
Name the manager/deputy and relevant supplier, engineer, local authority, water/waste and national incident contacts. Keep the information available when the usual computer or phone network is unavailable.
Assess backup storage, equipment, power or water arrangements before relying on them. Capacity, safe installation, transport, hygiene and operating instructions still matter; an improvised alternative is not automatically compliant.
Record the event and protect food
Record discovery time, known/uncertain conditions, products/batches, measurements and actions. SFBB cold-storage guidance includes breakdown decisions; avoid a universal “safe for four hours after any power cut” assumption.
If the facts indicate unsafe supplied food, use FSA business reporting in EWNI or Scottish arrangements. Do not wait for a complete final investigation before necessary protective action.
Worked example: an overnight power interruption
Hypothetical example: staff find a fridge cold after power has returned, but cannot establish the overnight temperature history.
The manager holds affected stock and uses the documented evidence/advice-based decision. The current reading does not reconstruct earlier food conditions or justify an invented safe outage period.
Test the plan and control restart
Run a proportionate scenario exercise: who notices, who decides, which food is held, how contacts/records are accessed and what evidence allows restart?
Check required cleaning/recommissioning, actual equipment/facility performance and any authority restrictions. Review the plan after an incident or changes in menu, capacity, supplier, equipment or premises.
Next steps
Test a water and refrigeration failure with staff and update missing contacts/decisions. Connect readiness checks and chilled-food checks with the emergency plan.
