Why Reefer Handoffs Matter

Reefer handoffs are the moments when refrigerated freight moves between a trailer and a warehouse. The goods leave one controlled space and enter another, often with a dock and a door in between. Most temperature problems in the cold chain show up at these points.

Careful handoffs keep that exposure short and documented.

Before the Doors Open

Check the reefer unit display. Record the set point and the current reading. Then compare them with the shipper’s instructions on the bill of lading or load sheet.

If the setting does not match, note it before unloading. A mismatch can explain later product problems and may affect who is responsible.

Reefer Handoffs at the Dock

Cold docks or sealed dock doors limit warm air. Staff should unload quickly and move pallets straight to the cold room. Pallets left on a warm dock lose temperature fast.

• Record the time the doors open and close
• Take product temperatures if the procedure calls for them
• Note any frost, condensation or leaks
• Photograph the load before unloading

Reefer Handoffs and Federal Rules

Food that needs temperature control for safety falls under the FDA’s sanitary transportation rule. It sets duties for shippers, loaders, carriers and receivers. The FDA sanitary transportation page summarizes them.

For specific obligations, ask a qualified compliance professional. The rule depends on the product and each party’s role.

Loading Outbound

Outbound reefer handoffs reverse the process. The trailer should be pre-cooled to the right setting before loading. Then staff load quickly, close the doors and record the setting and reading.

Air flow matters inside the trailer. Pallets packed tight against walls or the ceiling can block circulation. Loading patterns that leave space for air help hold temperature.

Records That Protect Both Sides

Every handoff record should show the trailer number, unit setting, reading, time and names. Add photos when possible.

These records support claims when a load arrives out of range. The guide on cold chain records explains how they fit together.

A Simple Example

Suppose a hypothetical dairy distributor receives a trailer with the unit set warmer than the shipper’s instructions. The receiving clerk records the setting, photographs the display and calls the shipper before unloading. That record helps the parties decide whether to accept the load and supports any later claim. The article on temperature excursion events covers what happens next.

Training the Dock Team

Good handoffs depend on habits. Staff should know the set points for common products, how to read the reefer display and when to stop and call a supervisor. A one page checklist at each cold dock door keeps the steps in front of them during busy shifts.
