Cold Chain SOPs for Pharma: The 10 SOPs You Need (with Sample Templates)

Purpose

To ensure cold chain products are received within their required temperature range and moved into correct storage without delay.

Scope

All incoming temperature-sensitive products at [site name].

Responsibilities

Stores personnel receive and inspect; QA reviews temperature data and decides on any excursion.

Procedure

1. 1Prioritise cold chain consignments over all other receipts.
2. 2Check the vehicle or shipper on arrival: seal intact, no visible damage, refrigeration unit running (for reefers).
3. 3Verify the delivery documents against the purchase order: product, batch, quantity, expiry and storage condition.
4. 4Retrieve the shipment's temperature data logger. Stop it and download or view the record.
5. 5Check the record for any reading outside the labelled range during transit.
6. 6If no excursion: move goods into the designated cold storage within [15] minutes of opening the shipper.
7. 7If an excursion is found, or the logger is missing or damaged: place goods in a quarantine area within the correct cold storage, label "Quarantine – do not use", and inform QA immediately (follow SOP 4).
8. 8Check vaccine vial monitors (VVMs) or temperature indicators where present.
9. 9Record the receipt in Form CC-01 and attach the logger report.

Records: Form CC-01 Cold chain receipt record; logger report; GRN.

Purpose

To store cold chain products under conditions that keep them within their labelled range.

Scope

All cold rooms, pharmaceutical refrigerators and freezers at [site name].

Responsibilities

Stores personnel; area in-charge for daily checks.

Procedure

1. 1Store products only in qualified, mapped equipment with a calibrated monitoring sensor.
2. 2Use only pharmaceutical-grade refrigerators. Domestic refrigerators are not permitted.
3. 3Do not store products in door shelves, against the back wall, near the evaporator, or on the floor.
4. 4Leave space between stacks and walls for air circulation, as defined in the mapping report.
5. 5Store products by FEFO (first expiry, first out). Keep labels visible.
6. 6Segregate quarantined, rejected and returned stock in clearly labelled areas.
7. 7Do not store food, drinks or non-pharmaceutical items in cold chain equipment.
8. 8Keep door openings short and infrequent. Plan picking to avoid repeated openings.
9. 9Keep freeze-sensitive products away from cold spots identified in mapping.

Records: Stock register; mapping report reference for each unit.

Purpose

To continuously monitor storage temperatures and respond to alarms before products are affected.

Scope

All monitored cold chain storage at [site name].

Responsibilities

Area in-charge for daily review; designated alarm responders (including after hours); QA for review and trending.

Procedure

1. 1Each storage unit has a calibrated, continuously recording sensor placed at the location defined by mapping.
2. 2Set alarm limits: [high and low alarm limits, e.g. 3°C and 7°C for a 2°C to 8°C unit] with a delay of [10–15] minutes to avoid false alarms from door openings.
3. 3Configure alerts by SMS, email and app to at least two responders, with escalation to [QA head / site head] if not acknowledged within [15] minutes.
4. 4Daily: review the monitoring dashboard or display at [time], and record current, minimum and maximum readings in Form CC-02 (or confirm in the system).
5. 5On an alarm: the responder acknowledges it, checks the unit within [15] minutes, and identifies the cause (door open, power, compressor, sensor).
6. 6Take immediate corrective action: close the door, restore power, or move products to backup storage (SOP 9).
7. 7If the reading went outside the product's labelled range, start SOP 4.
8. 8Record every alarm, cause and action in Form CC-03.
9. 9Test alarms [quarterly] by simulating a high and low condition. Record results in Form CC-04.
10. 10QA reviews monitoring data and alarm logs [monthly] for trends.

Records: Form CC-02 Daily temperature review; Form CC-03 Alarm log; Form CC-04 Alarm test record; system audit trail.

Purpose

To assess and decide on products exposed to temperatures outside their labelled range.

Scope

Excursions in storage, receipt or transport at [site name].

Responsibilities

Person who detects the excursion reports it; QA investigates and decides product disposition.

Procedure

1. 1Immediately protect the product: move it to correct storage and quarantine it. Do not discard anything yet.
2. 2Report the excursion to QA within [1] hour using Form CC-05.
3. 3Record: unit, products and batches affected, start and end time, minimum or maximum temperature, and total duration outside range.
4. 4Download and attach the full temperature record.
5. 5QA assesses the impact using the manufacturer's stability data or excursion guidance. Contact the manufacturer where needed.
6. 6Check freeze-sensitive products for freezing, including a shake test where applicable and validated.
7. 7QA decides disposition: release, release with restrictions, or reject.
8. 8Raise a deviation and investigate root cause.
9. 9Raise CAPA to prevent recurrence and set an effectiveness check.
10. 10Notify customers or the marketing authorisation holder where product already dispatched may be affected.

Decision flow

Records: Form CC-05 Excursion report; deviation; CAPA; disposition decision.

Purpose

To pack cold chain products so they stay within range for the full journey.

Scope

Procedure

1. 1Use only qualified shipper and packing configurations, matched to route duration and season.
2. 2Condition gel or ice packs as specified in the packing instruction, for example [2°C to 8°C conditioned packs for 2°C to 8°C products]. Never place frozen packs directly against freeze-sensitive products.
3. 3Pre-condition the shipper if the packing instruction requires it.
4. 4Pack products, coolants and a started temperature logger exactly as shown in the packing diagram.
5. 5Place the logger with the product, not against a coolant pack or the box wall.
6. 6Seal the shipper and label it with storage condition, "Keep refrigerated" or equivalent, and orientation arrows.
7. 7Record packing time, shipper type, number of coolant packs and logger serial number in Form CC-06.
8. 8Hand over to the transporter only when the vehicle and dispatch timing are confirmed.

Responsibilities

Logistics in-charge; transporters under a quality agreement.

Procedure

1. 1Use only qualified vehicles or transporters approved by QA under a quality agreement.
2. 2Pre-cool the reefer to the set point before loading, and record the temperature.
3. 3Load quickly, without blocking airflow from the refrigeration unit.
4. 4Monitor temperature throughout the journey with a calibrated logger. Use real-time GPS loggers for high-value or long routes.
5. 5Drivers must not switch off refrigeration during stops and must keep doors closed except for loading and unloading.
6. 6If an alert is received in transit, the driver and logistics in-charge follow the contingency plan: check the unit, divert to a backup cold store, or transfer to another vehicle.
7. 7Record any delay, breakdown or alert in Form CC-07.
8. 8On delivery, the receiver checks the logger data (SOP 1).
9. 9Qualify routes by profiling summer and winter conditions for long or high-risk lanes.

Scope

Cold rooms, refrigerators, freezers and controlled storage areas.

Responsibilities

Engineering and QA; validation team or approved contractor.

Procedure

1. 1Prepare a mapping protocol defining the area, logger number and positions (a 3D grid covering corners, centre, top, bottom, doors and near cooling units), logging interval, duration and acceptance criteria.
2. 2Use calibrated loggers with valid certificates.
3. 3Map empty and loaded states, and summer and winter conditions where ambient affects performance.
4. 4Run the study for a duration that captures normal operation, defrost cycles and door openings, typically several days.
5. 5Include tests such as door opening and power-off recovery where relevant.
6. 6Analyse results: identify hot and cold spots, check all points stayed within limits, and calculate recovery time after door openings.
7. 7Write a mapping report with conclusions and approved monitoring sensor locations.
8. 8Re-map after major changes (equipment, layout, racking) and at a defined frequency, for example every [2–3] years or as risk assessment requires.

Records: Mapping protocol; mapping report; logger calibration certificates.

Purpose

To ensure temperature sensors and loggers read accurately.

Scope

All sensors, loggers and thermometers used for cold chain monitoring and mapping.

Responsibilities

Engineering or metrology; QA for review.

Procedure

1. 1Maintain a list of all monitoring devices with serial numbers, locations and calibration due dates.
2. 2Calibrate each device at least [annually], or more often for critical uses or devices with a history of drift.
3. 3Use a calibration laboratory accredited to ISO/IEC 17025 (NABL in India), or traceable to national standards as defined by QA.
4. 4Calibrate at points that bracket the use range. For 2°C to 8°C, use points around 0°C, 5°C and 10°C.
5. 5Review each certificate on receipt: serial number match, points, as-found and as-left readings, uncertainty, and pass or fail against your acceptance limit.
6. 6If a device is found out of tolerance (as-found), assess the impact on all data recorded since the last calibration and raise a deviation.
7. 7Replace devices sent for calibration with calibrated spares so no location goes unmonitored.
8. 8Label each device with its calibration status and due date.

Records: Calibration schedule; certificates; out-of-tolerance impact assessments.

Purpose

To protect products when power fails or cold chain equipment breaks down.
