Transport and routing33 / 35

Compare like-for-like service conditions, then document logger data, excursion notification and subcontractor responsibilities.

Three limits set trip frequency: shelf life left at delivery, the store's cold storage volume and its rate of sale. A small calculation shows how many trips a week each store needs.

Compare pallets and crates by store access, handling steps, delivery time, and empty returns.

A bag is the container for short routes measured in hours. Choose by closure, lining, pack divider and logger position, then test it loaded on your own route.

Do not simply add the first batch to an existing route. Verify product needs, packaging, receipt and temperature records in a limited pilot.

Assess manufacturer nesting data for the Rocotec model separately from measured containers and vehicle capacity on empty returns.

A refrigerated trailer's internal size is smaller than its outside; at 13.4 m internal length the count comes to 33 pallets. The stacking plan is built on net internal size, air clearance and axle distribution.

Assess a strip curtain with the doorway, strip overlap, loading visibility, cleaning and airflow; decide from matched route records.

Most cut flowers travel at 0-1 °C and high humidity, chilling-sensitive tropicals above 10 °C. Ethylene, condensation and box layout shape vase life as much as temperature does.

There is no single valid opening count. What wears a container down is the total time the lid stays open over the round; as openings add up, the cold source cannot take the heat back.

Check each veterinary product's authorised storage conditions, route log, and decision owner. Do not assume human-medicine rules apply.

The log gives the minutes and a comparison of two methods on the same route gives the litres. Warm air leaking in at door openings can reach about a third of the refrigeration load of a delivery truck.

Shows where the time window starts, how to separate the laboratory's acceptance limit from actual arrival records, and how a route is checked against a 4-hour serum benchmark in a worked example.

Preloading product measurement, door-event duration and thermal records are read together; none alone decides safety or release.

Link depot exit, dock, vehicle and handover in one shipment record. Make waiting and monitoring gaps visible.

Unopened insulin stays in the fridge at 2-8 °C and is never frozen. The period and temperature for a pen in use come from the product information.
