The short answer

This page is the shipper inspecting the carrier's empty trailer before loading. It is different from freight inspection, where the carrier inspects the shipper's freight after pickup.

Do these first

Inspect before the first pallet goes in.

  • Check the floor — OSHA requires checking trailer flooring for breaks and weakness before powered industrial trucks enter.
  • Look at walls and roof — note visible damage, openings or moisture concerns.
  • Check doors — verify they operate and visible damage is documented.
  • Photograph questionable conditions — do it before freight hides the area.

Floor condition comes first

OSHA requires trailer flooring to be checked for breaks and weakness before powered industrial trucks are driven onto it.

That is the first safety check because a forklift places concentrated load on the trailer floor.

Do not send a forklift into a trailer with a visibly unsafe floor.

Walls, roof and visible openings

Look for visible conditions that could affect the load, such as:

  • Holes
  • Torn interior panels
  • Exposed sharp surfaces
  • Visible moisture
  • Water staining
  • Debris

This is a condition check, not a structural engineering inspection.

If something looks wrong, stop and resolve it before loading.

Odor, debris and contamination concerns

Some commodities are sensitive to:

  • Strong odors
  • Dirt
  • Residue
  • Moisture
  • Previous-cargo contamination concerns

The shipper's commodity requirements determine whether the trailer is acceptable.

Do not use this page to invent food-sanitation standards.

For food and temperature-controlled freight, use reefer airflow and loading and the shipper's own sanitary instructions.

Doors and seals

Before loading, inspect visible door condition and make sure the doors can close properly.

If the shipment requires a numbered seal, confirm the seal procedure after loading.

Record the seal number in the shipment paperwork where required.

Reefer-specific condition

For a reefer, also check:

  • Air chute condition
  • Floor airflow channels
  • Visible interior cleanliness
  • Refrigeration-unit condition as required by the shipper/carrier process
  • Required temperature preparation

Do not duplicate the airflow guide here.

Photograph before loading

Photos are most useful before freight blocks the trailer surfaces.

Consider documenting:

  • Empty trailer interior
  • Floor
  • Walls
  • Ceiling
  • Doors
  • Any existing damage
  • Moisture or residue concerns

That can help separate pre-existing trailer condition from freight damage discovered later.

Tell me if the trailer is not acceptable before loading

Document the condition and call before the freight goes in so the equipment issue can be solved while the trailer is still empty.
