Winter storms in the Midwest can cause sudden power outages that put food safety at risk. Restaurants, cafés, grocery stores, bakeries, and cafeterias must be ready long before the lights go out. Whether your business is in Detroit, Grand Rapids, Ann Arbor, Lansing, Flint, Toledo, Columbus, Cleveland, Cincinnati, Fort Wayne, South Bend, or Indianapolis, having a clear plan and reliable backup cold storage is essential.

This guide explains the most important steps to take before and during a power outage and highlights why Emergency Refrigeration, Emergency Freezer Solutions, and Temporary Cold Storage can protect your inventory and operations

Know Local Rules Before a Power Outage

Local health departments have different requirements during a power failure. Some will require you to close immediately. Others may allow you to remain open if you only sell prepackaged non-TCS foods.
If you use generators or other backup power sources, confirm that they meet local regulations before an emergency happens.

Build an Emergency Refrigeration Plan

Without power, cold foods can become unsafe quickly. Having a plan for Temporary Cold Storage and Emergency Refrigeration solutions can prevent losses and keep operations stable. Many food businesses use:

• Emergency Refrigeration or Cold Storage units

• Mobile Emergency Freezer Solutions

• Temporary Emergency Freezer Units for overflow

• On-demand portable refrigeration trailers

These solutions can protect meats, dairy, seafood, sauces, produce, baked goods, and frozen inventory through long outages.

This is especially important during winter storms in Michigan, Ohio, and Indiana, where outages may last several hours or multiple days.

What To Do When the Power Goes Out

1. Keep Employees and Customers Safe

Safety must come first. If the dining room is dark, help customers exit with flashlights. Assign each employee a clear responsibility from your emergency action plan.

2. Halt All Unsafe Food Preparation

If you lose hot water, water pressure drops, lighting is too dim, or you cannot keep foods below 41°F or above 135°F, stop preparing food immediately. Continuing to cook in unsafe conditions can result in contamination and violations.

3. Protect Refrigerated and Frozen Food

To slow temperature rise and maintain safety:

• Keep refrigerator and freezer doors closed

• Place ice bags or frozen water containers inside units

• Record the exact time power is lost

• Track temperatures if you have internal thermometers

Important temperature guidance:

• Refrigerators remain safe for up to 4 hours

• A full freezer stays cold for 48 hours

• A half-full freezer stays cold for 24 hours

Discard any food that stays above 41°F for more than 2 hours.
Discard any food that was being cooked but did not reach its safe internal temperature.

4. Document Everything

Note the power-outage timeline, temperature readings, and any product you discard. This helps with insurance reviews and health inspections.
