The reefer reading is on a slip. The exception form is separate. You set the crumpled reefer unit printout next to the signed exception note you jotted when you pulled the load’s rear door, fingers still cold from the 34-degree air that billowed out when the latch popped. You cross-reference both documents before you log anything in your system, because mismatched temp notes create weeks of back-and-forth if you miss the gap now. A small smudge of berry juice stains the corner of the exception form, leftover from the single crushed clamshell you spotted on the top pallet when you first peeked inside, and you make a mental note to include that detail in your remarks if the temperature lines do not align.

Name Both Recorded Temperature Lines

Both lines carry weight for different reasons, so you label each clearly on the top of the exception form to avoid mix-ups later. The first line comes directly from the reefer unit’s on-board computer, which logs a temperature reading every 15 minutes for the entire duration the unit is running. This sensor is mounted near the unit’s air output, so it measures the temperature of the air being pumped through the trailer, not the actual temperature of the product inside sealed boxes or stacked pallets. The second line is the manual reading you took with your dock’s hand-held probe, inserted 6 inches into the center of the top pallet’s middle box, 30 seconds after you opened the rear doors, before any warm dock air could alter the product’s surface temperature. This reading measures the actual temperature of the product at the point of delivery, rather than the air circulating through the trailer. Illustrative example: The reefer unit log line shows an average in-transit temperature of 32 degrees for the 12-hour haul from central California to your Portland dock, while your manual probe line shows a load temp of 41 degrees at the time of unload. The table below outlines key details for both lines to make cross-referencing simpler:

Line Source Data Collection Timeframe Recorded Temperature Last Sensor Calibration Date
Reefer Unit Log Line Full 12-hour in-transit haul 32°F average 10/12/2024
Manual Exception Form Line Moment of door opening, pre-unload 41°F spot reading 11/02/2024
Combined Reference Line Full shipment lifecycle 32°F in-transit / 41°F at delivery N/A

You can cross-reference these line details against any load records stored in Dock Tally if you need to pull historical calibration data for either sensor, or confirm the shipment’s scheduled arrival window matches the timestamps listed on both documents. You double-check that both lines are transcribed correctly on the exception form, with no typos or transposed digits, because even a 2-degree error can lead to unnecessary confusion later.

Mark Which Recorded Line Controls Dispute Resolutions

Once you have both lines clearly labeled and verified, you mark which recorded line controls dispute resolutions by circling it in blue ink on both the reefer slip and the exception form, then initialing next to the circle so any team member reviewing the documents later knows you verified the selection. You only use blue ink for this mark, per your team’s standard operating procedure, so the mark stands out clearly against the black printed text and any black ink notes you wrote on the exception form earlier. The reefer unit log line controls if the load shows no signs of temperature-related damage, such as thawed produce, melted frozen goods, or condensation on product packaging, because it represents the full temperature environment the load was exposed to during transit. The manual exception form line controls if you spot visible temperature-related damage when you first open the doors, because it confirms the load’s actual state at the point of transfer, regardless of the unit’s logged data.

For the illustrative example listed earlier, if you notice 12 pallets of raspberries are thawed and leaking juice when you open the door, you circle the manual 41°F line as the controlling line, and write “thawed berry pallets noted at unload, damage observed” in the blank space at the bottom of the exception form. If no damage is observed, even with the 9-degree gap between the two lines, you circle the reefer unit’s 32°F average line as the controlling line, and note “no product damage observed at unload” below. This clear, documented selection eliminates ambiguity later when teams review the shipment paperwork to address any questions about temperature conditions during transit. This step reduces unnecessary follow-up questions from both your operations team and the carrier’s admin team when discrepancies are flagged, and ensures everyone reviewing the documents has the same context you had at the time of delivery.

File This Page With Associated Shipment Paperwork

Next, you file this page with associated shipment paperwork to ensure it is easily accessible for future reference. You first attach the reefer slip to the back of the exception form, making sure both circled controlling lines are visible when you flip through the shipment packet, so no one has to separate the documents to see the marked line. You align the top edges of both documents and staple them once in the upper left corner, so they do not separate from the rest of the delivery paperwork, which includes the signed bill of lading, the delivery receipt, any photos you took of the load upon opening, and the driver’s signed proof of delivery. You check that all pages are ordered with the bill of lading first, then the delivery receipt, then the exception form with the attached reefer slip, then the printed photos, so the paperwork follows the standard order your team uses for all reefer shipments.

You place the combined documents in the “completed delivery” filing slot for your shift, rather than tucking them into a personal folder or leaving them on the dock edge where they can be lost, damaged, or mixed up with paperwork from other loads that arrived the same day. If your team uses digital filing for shipment documents, you scan both the front and back of the exception form and the attached reefer slip, and upload the file to the shipment’s digital folder within 10 minutes of completing the unload, so remote team members can access the documents immediately if needed. You double-check the scan to make sure the circled controlling line and your initials are clearly visible, and that the file is labeled with the shipment’s pro number so it can be easily searched later.

Next Time You Open This Page For Reference

Next time you open this page for reference, whether it’s two days or six months from now, you first confirm that both temperature lines are still legible and that your initials next to the controlling line are visible. You cross-check the controlling line against any notes or photos attached to the shipment packet to confirm the selection you made at the time of delivery aligns with any later observations of the load’s condition during unload. If you are sharing this page with a member of the carrier’s operations team, you point to both lines first, then the written reason for your controlling line selection, so they have full context for the discrepancy between the two readings without needing to ask you for additional details.

You do not alter any marks on the page once it is filed, even if you later remember a detail you forgot to write down, because altering official shipment documents after the fact erodes trust between your team, the carrier, and the shipper who sent the load. If you need to add additional context later, you write the note on a separate, clearly labeled slip of paper, date it, sign it, and attach it to the back of the existing paperwork so the original temperature notes remain unmodified. If you are reviewing the page to answer a question from the shipper about the load’s condition upon delivery, you reference both lines first, then explain the reason for the controlling line selection, and share any attached photos of the load at the time of unload to support your selection. This structured approach to reviewing the page ensures all parties have the full context of the delivery’s temperature status, and reduces the amount of back-and-forth required to resolve any questions or concerns about the shipment. You always return the page to its proper place in the shipment packet once you are done reviewing it, so other team members can access it easily if they need to reference it later.
