Blood Bank Cold-Chain Excursion Records

After a storage-temperature excursion, create one incident file that connects the temperature evidence, affected units, equipment status, escalation, disposition and closure. An assessor should be able to start with either the equipment number or a unit identifier and reconstruct the whole event.

Apply the disposition criteria in your centre’s approved temperature-excursion SOP against the applicable storage requirements. A reading outside the normal range does not create one universal discard decision, but it does require a documented assessment for every unit within the event’s defined scope.¹²

Build the evidence in event order

Schedule F Part XIIB of the Drugs and Cosmetics Rules, 1945 provides the legal baseline for blood and component storage conditions and storage equipment.¹ Your current NABH standards and the National Standards for Blood Centres add quality-system expectations around equipment monitoring, nonconforming products, records, incidents and corrective action.³⁴

Handle the event in five recorded stages: detect and timestamp it, control the stock, define the unit-level scope, assess disposition under the approved SOP, and reconcile the units and equipment before closure. If the time window or logger data is incomplete, record the uncertainty and use the escalation route in your SOP instead of creating an unsupported estimate.²

Taken together, the event file should contain the following evidence:

Record the equipment by asset identifier, not merely as “blood refrigerator”. Where the assessment or return-to-service decision relies on alarm behaviour, operating limits or recovery instructions, retain the instructions for the exact equipment model or the manufacturer’s documented technical response.⁵

Identify every unit within the event scope

Use your approved SOP to define how the event’s start and end are established. Preserve the readings, alarm history or temperature chart used to derive that window, then identify every unit present in the equipment during the evaluated period.²

Capture the inventory before transfers and status changes erase the useful view. If a technician empties the refrigerator and prints the current stock report afterwards, an assessor sees an empty refrigerator, not the units that were exposed.

For each unit, record the unit identifier, component, location during the event, relevant entry or removal time, immediate control and final disposition. Units moved or issued before the excursion was discovered still belong in the reconstruction if their storage history places them within the evaluated window.

Opening and closing totals cannot provide this evidence. Unit identifiers connect the incident to your centre’s wider donor-to-recipient traceability, while a preserved event-time inventory avoids the historical gaps behind many inventory management failures.

When staff amend the affected-unit list, retain the original entry or system audit trail, the reason for the change, and the person and time responsible. A silently replaced spreadsheet leaves no way to tell whether a unit was genuinely outside the event or removed from the list later.

Record why each disposition was made

Schedule F and the National Standards for Blood Centres provide the applicable storage baseline. Your approved procedure should state how staff assess an excursion and who may authorise the resulting disposition.¹⁴ Your Drugs and Cosmetics Rules compliance controls should identify the exact requirement used in that assessment.

For each unit, or for a clearly defined group of units with the same relevant conditions, record:

• The unit identifiers covered by the decision.
• The temperature evidence and evaluated exposure window.
• The applicable component storage requirement.
• The SOP title, version and decision criterion used.
• Any validated study or equipment-manufacturer instruction relied upon.
• The authorised person, decision, reason, date and time.
• The release, transfer, continued quarantine or discard transaction that completed the decision.

If the approved SOP does not cover the observed condition, document the escalation and the additional evidence obtained. Manufacturer advice can form part of the assessment, but the authorised person named in your procedure must record the unit disposition.²⁵

A group decision still needs an attached unit list. “All stock accepted” cannot be reconciled against inventory unless the record identifies exactly which stock the words cover.

Close the equipment and stock separately

Resolving the affected units does not automatically return the equipment to service. Conversely, a repaired refrigerator does not resolve the disposition of stock removed from it. Keep both closure paths visible under the same incident number.

For the equipment, preserve the findings, maintenance or repair report, checks required by your SOP, and the person and time authorising return to service. Include calibration, alarm or monitoring verification when your procedure or the manufacturer’s instructions require it.³²⁵

For the stock, reconcile every identifier on the affected-unit list against a final status and transaction. The incident can then carry the investigation findings, notifications, corrective action where applicable, effectiveness review where required, closure approval and closure date. These records are central to the evidence reviewed during a NABH assessment.³

Retain one linked record that staff can retrieve

Rule 122G requires the records and registers specified under Schedule F Part XIIB to be maintained for five years, a period its licence conditions tie to the date of manufacture for testing records.⁶ Map the excursion form, temperature data, affected-unit list, maintenance documents and disposition evidence in your record-control schedule; how that period is counted is covered in the blood bank record retention guide.

A shared incident number is the simplest retrieval control. Put it on the temperature-chart annotation, inventory list, movement or quarantine records, service report, disposition approval and closure record.

Before filing the event, ask a technician who was not involved to retrieve it from a unit identifier. If they can find the excursion evidence, decision basis, final unit status and equipment closeout without relying on the incident lead’s memory, your centre can show what happened rather than merely state that the SOP was followed.
