Temperature Excursions: A Medical Courier Response Guide

1. Pause and protect the shipment

Check the shipment's written handling and escalation instructions. Maintain custody and follow those instructions for the package and its monitoring device. Do not improvise a temperature adjustment or open packaging unless the instructions or designated contact direct it. Do not discard the shipment or decide on your own that it is acceptable to release. If directions are missing or conflict, contact the designated customer or shipper contact through the listed escalation path.

2. Record readings and both event times

Make each entry understandable on its own. Record the shipment or run identifier; the reading's exact value and unit; when the reading was taken; when you discovered the excursion; and the date, local time, and time zone for each. If your system records Celsius or Fahrenheit, label the unit and preserve the original device value rather than silently converting it.

• Identify the logger or probe, the measurement point, and whether the value came from a live display, alert, or downloaded record.
• Add the minimum, maximum, duration, or start time only when the device or reliable shipment record provides it. Mark estimates as estimates; do not fill gaps by guessing.
• Preserve the original logger data or export and note the package condition and shipment location when the issue was discovered.

3. Notify the designated customer or shipper contact

Use the contact and escalation sequence in the shipment instructions or customer procedure. Report the shipment identifier, observed readings and times, current location, and custody status using an approved channel. If the first contact does not respond, follow the listed backup or dispatch escalation; do not substitute an unverified contact.

In the log, record whom you contacted and their role or team, the channel used, when you first attempted contact, when it was acknowledged, what direction was given, and when any promised follow-up occurred. If you are still waiting, record that status and the next follow-up time.

4. Document actions and handoffs as they happen

Add a time-stamped note for each action: who took it, what changed, where the shipment was, and which instruction or contact directed the action. Include any change in custody, package or seal observation, route pause, transfer, or condition-monitoring step that applies to the shipment. Record notifications and replies in the same timeline so the order is clear.

Keep the initial readings and event notes intact. If a correction is needed, follow the record system's amendment process so the original entry, correction, author, and correction time remain traceable.

5. Record the disposition; do not make the release decision

Follow the applicable shipment instructions while awaiting direction. Record the disposition supplied by the designated customer or shipper authority, including who provided it, their organization or role, when and how it was received, and the action they directed. Do not infer that a shipment is released, usable, or safe from a single reading. If no disposition has been recorded, mark follow-up as pending and continue the stated escalation path.

At handoff or closeout, record who received custody, when it transferred, and where the logger data and event record were stored or sent under the customer's process.

6. Keep every response shipment-specific

There is no single temperature limit or allowable excursion duration for every medical shipment. Check the package labeling, shipping documents, customer standard operating procedure, and the designated contact's instructions for that cargo. For product-specific questions, the customer or shipper should use the applicable manufacturer and program guidance. This field guide is operational information; it is not a regulatory compliance certification or a substitute for shipment instructions.
