    Study Notes

    Intermodal Containers

    • Intermodal containers are transported on various vehicles (chassis or non-chassis)
    • Securing procedures differ depending if the container is loaded, empty, or on a chassis or non-chassis vehicle
    • Loaded containers on chassis vehicles require securing using at least two latches on the chassis engage anchor points, on the front and rear of the container.
    • Loaded containers on non-chassis vehicles should be secured by chains, wire ropes, or integral locking devices to all lower or upper corners of the vehicle.
    • Containers must be secured to prevent:
      • Movement more than 1.27 cm (1/2 inch) forward or backward
      • Movement more than 1.27 cm (1/2 inch) to the left or right
      • Movement more than 2.54 cm vertically (1 inch)
    • Securing devices should be independently attached, and cannot come loose unintentionally.
    • If a latch breaks or goes missing use alternative securing methods (e.g. chain, wire rope)
    • When securing cargo inside an intermodal container, follow general cargo requirements or specific cargo guidelines.
    • Empty containers on non-chassis carriers must meet four requirements:
      • Balanced and stable positioning.
      • Cannot hang over front/rear more than 1.5 meters (5 feet).
      • Cannot interfere with vehicle maneuverability.
      • Securing to prevent unintended movement.

    Overview of Loading/Unloading Procedures

    • Prioritize safety when loading/unloading containers.
    • Park on a level surface and use parking brakes.
    • Check the container and loading area thoroughly (damage, hazards, debris).
    • Communicate with dock workers.
    • Ensure proper lighting and use appropriate protective gear.
    • Secure cargo properly using appropriate tie-down methods.
    • Distribute weight evenly within the container.
    • Check for shifting cargo before closing the container doors.
    • Be aware of pedestrians and other vehicles in the area. Avoid pinch points when opening the doors.
    • Never leave the vehicle unattended during loading/unloading.
