Who sets the rules
In India, blood centres are licensed by the State Drugs Control (Licensing) Authority with approval from the Central Drugs Standard Control Organization, under the Drugs and Cosmetics Act and Rules. The National Blood Transfusion Council's National Standards for Blood Centres and Blood Transfusion Services — first published in 2007 and since revised — are the main technical guidance on how blood centres should operate, including storage.
Equipment purchases should start from those documents and your licence conditions, not from a supplier's brochure.
Storage conditions in the national standards
Platelets are the reminder that blood storage is not just about cold: they are kept near room temperature and agitated, and a refrigerator is the wrong place for them.
| Equipment | Inside temperature | Also expected |
|---|---|---|
| Blood centre refrigerator or walk-in cooler | 4 °C ± 2 °C | Continuous monitoring or recording at least every 4 hours; alarm; alternate power supply |
| Deep freezer for plasma and components | −30 °C or −80 °C | Temperature indicator or recorder; alarm; alternate power supply |
| Platelet incubator with agitator | 22 °C ± 2 °C | Continuous gentle agitation; recorder; alarm; alternate power supply |
How a blood bank refrigerator differs from a pharmacy fridge
- A narrower band — 4 °C ± 2 °C rather than +2 to +8 °C — so uniformity across the whole cabinet matters even more.
- Continuous temperature recording, often with a chart or electronic recorder built in; the standards advise two recording systems.
- Alarms that sound where someone is present round the clock, not just at the cabinet.
- Shelves or drawers designed for blood bags so air reaches every unit and bags aren't crushed.
- Dedicated use: blood, components and blood samples only. Reagents go in separate refrigerators.
Monitoring and calibration
The national standards call for blood storage refrigerators, freezers and platelet incubators to be monitored continuously, or at least every four hours where continuous monitoring isn't in place. Their calibration annex expects the temperature recorder to be compared against a calibrated thermometer daily, with periodic calibration of recorders and storage thermometers.
In practice that points to an independent, calibrated logger alongside the built-in recorder, with records reviewed daily and kept as your licence requires.
Power and contingency
The standards treat a regular 24-hour electricity supply as essential and require provision of a backup generator, plus an alternate power supply for each storage device. They also ask for adequate alternate storage and written instructions displayed in the storage area for what to do if power or equipment fails.
For equipment buyers, that means checking how each cabinet behaves on power loss and restart, choosing alarms with battery backup, and making sure the generator changeover is fast enough that cabinets stay in band.
Site conditions in Indian hospitals
Blood centres in district hospitals may sit in rooms that are not air-conditioned around the clock. Ask for the rated ambient at which a refrigerator holds 4 °C ± 2 °C evenly, leave the manufacturer's clearances and keep condensers clean — dust is a common cause of drifting temperatures. Protect compressors with suitable voltage stabilisation, and keep the generator's fuel, maintenance and test records in order.
Questions to ask before buying
- Does the unit's range, uniformity and recorder meet the current national standards and your licence conditions?
- What is the rated ambient, and what uniformity data exists at that temperature?
- How do alarms reach staff away from the cabinet, and do they work during a power cut?
- Is the shelving designed for blood bags and your daily throughput?
- Who services it locally, and how quickly?
Frequently asked questions
- Can a standard pharmacy refrigerator be used for blood?
- Blood storage has its own band (4 °C ± 2 °C), recording and alarm expectations under India's national standards and blood centre licensing. Use equipment that meets those requirements and confirm with your licensing authority.
- Can reagents be stored in the blood bank refrigerator?
- The national standards say refrigerators or freezers used for blood and components should hold only blood, components and blood samples, with reagents kept in separate refrigerators.
