Why do blood fridges require separate alarm and control systems?
Blood fridges require a higher level of monitoring because they are used to store blood and blood products that may later be transfused into patients. If the fridge temperature moves outside the required range and the issue is not detected quickly, the stored blood products may no longer be safe or suitable for use. A compliant blood fridge should have an alarm system that is separate from the temperature control system. The control system manages the fridge temperature, while the alarm system independently monitors for temperature faults or other issues. This separation is important because a fault in the control system should not also disable the alarm function. If the fridge fails to maintain the correct temperature, staff need a reliable warning so they can respond before blood product safety is compromised. This is one of the key differences between a blood fridge and a standard medical or vaccine fridge.Do blood fridges need TGA approval or ARTG inclusion?
Blood fridges used for the storage of blood and blood products must be included in the Australian Register of Therapeutic Goods (ARTG) before they can be supplied in Australia. The ARTG is administered by the Therapeutic Goods Administration (TGA), and blood refrigerators appear in the ARTG as Class IIa medical devices.ARTG inclusion is separate from AS 3864 compliance. AS 3864 deals with blood storage performance, equipment requirements, temperature recording, alarms, testing and ongoing verification. ARTG inclusion relates to whether the medical device can be lawfully supplied in Australia.
When choosing a blood fridge, check that the model has the correct ARTG status, complies with AS 3864.1-2012, and can be installed, verified, calibrated and maintained in line with AS 3864.2-2012.
ENLAKE blood fridges are included in the ARTG and are supplied with the documentation needed to support compliant installation and use.What is the difference between a blood fridge and a vaccine fridge?
A blood fridge is built for storing blood and blood products. A vaccine fridge is built for vaccines and temperature-sensitive medicines. They are not the same product category, and the compliance requirements are different.| Requirement | Blood fridge | Vaccine fridge |
|---|---|---|
| Main use | Blood and blood products that may be transfused into patients | Vaccines and temperature-sensitive medicines |
| Storage range | 2°C to 6°C | Typically 2°C to 8°C |
| Australian Standard | AS 3864, Medical refrigeration equipment – For the storage of blood and blood products | Vaccine cold chain requirements |
| Alarm system | Separate from the temperature control system | Not usually equivalent to AS 3864 blood storage requirements |
| Temperature records | Reliable temperature recording and audit trail capability | Temperature records required, but to a different standard |
| ARTG / TGA | Must be included in the Australian Register of Therapeutic Goods (ARTG), unless a specific exemption, approval or authority applies | ARTG inclusion is generally not required for standard vaccine refrigeration equipment |
What needs to happen before a blood fridge is used?
Before a blood fridge is used to store blood or blood products, the facility needs to confirm that the fridge is suitable for blood storage, installed correctly, operating within the required temperature range, recording temperatures properly, and alarming correctly. AS 3864.1-2012 covers the manufacture and performance of the fridge itself, while AS 3864.2-2012 covers what happens after installation, including care, maintenance, performance verification, calibration and ongoing monitoring.
In practical terms, commissioning includes checking the installation location, allowing the fridge temperature to stabilise, arranging NATA-accredited spatial temperature mapping, verifying temperature monitoring accuracy, testing high/low temperature alarms, testing power failure alarms, checking remote alarm notifications (if the site is not staffed 24 hours a day), and keeping the required documentation for compliance and audit purposes. AS 3864.2 also states that equipment used for blood and blood products needs appropriate monitoring, alarms, maintenance, servicing, performance verification and calibration, and that testing/calibration should be repeated when equipment is moved or has significant maintenance or repairs.
ENLAKE can assist by helping select a compliant blood fridge, checking practical site requirements, supplying the required product documentation, and arranging calibration, verification, spatial mapping and service support through our suitable partners. This gives the client one coordinated pathway from quote to a fridge that is ready to be assessed for blood storage use.
What features should a compliant blood fridge include?
A blood fridge should be built specifically for blood and blood products, not general medical stock.
Important features include stable temperature control, forced air circulation, continuous temperature recording, high and low temperature alarms, a power failure alarm, suitable internal storage, and rated blood pack capacity.
The alarm and monitoring system matters as much as the fridge itself. Temperatures need to be recorded securely, sensors need to reflect the temperature of the stored blood packs, and alarms need to be available where staff can respond if the fridge moves outside range.
The fridge should also be supplied with operating instructions, installation requirements, cleaning and maintenance instructions, and details of the ambient temperature range it is designed to operate in.
ENLAKE can help specify a blood fridge with the right capacity, monitoring, documentation and service support for your facility.How do I choose the right blood fridge for my facility?
The right blood fridge depends on what you need to store, how much capacity you need, where the unit will be installed, and how the fridge will be monitored.
For a hospital blood bank, that may mean a larger upright unit with higher storage capacity and remote alarm connection. For a theatre, clinic, laboratory or satellite site, a smaller under-bench model may be more practical, provided it still meets the same blood storage requirements.
Things to check include blood bag capacity, available space, ambient temperature, alarm requirements, temperature recording, calibration, verification, documentation, and access to service support.
ENLAKE can help assess your site requirements and recommend a compliant blood fridge that suits your storage volume, monitoring needs and installation conditions.What temperature range is required for blood storage?
Blood and blood products that require refrigerated storage must be held between 2°C and 6°C. Frozen plasma and plasma products must be stored at -25°C or lower.
In Australia, blood storage refrigeration equipment is covered by Australian Standard AS 3864, Medical refrigeration equipment — For the storage of blood and blood products. AS 3864.1-2012 covers the manufacture and performance requirements for the equipment, while AS 3864.2-2012 covers the ongoing care, maintenance, performance verification and calibration needed after installation.
For this reason, blood should only be stored in purpose-built medical refrigeration equipment designed for blood storage — not in a domestic, pharmacy, vaccine or general-purpose laboratory fridge. A compliant blood fridge must maintain the required temperature range, provide temperature monitoring and alarms, and generate the records needed to support safe storage and compliance.
