Blood Banks and Blood Safety

Key strategies for blood safety include ensuring consistent electricity and refrigeration to maintain blood supplies at blood banks.
In many developing countries, reliable power is rarely available. Access to grid power, especially for rural facilities, simply may not be available. This lack of power or lack of steady power jeopardizes the ability of blood banks to store safe blood and blood components. Whole blood or its component must be stored, without interruption at temperatures near or below zero degrees Celsius. Failure to maintain these conditions can result in the wholesale loss of blood.
Blood Products | Storage Temperature and Condition | Shelf Life |
---|---|---|
Whole Blood | 2-6°C | 28-35 days |
Red Cells in Additive | 2-6°C | 42 days |
Platelet Concentrate | 20-24°C under constant agitation | 5 days |
Frozen Plasma | Below -30°C | 365 days |
Cryoprecipitate | Below -30°C | 365 days |

How can continuous power be provided to a blood bank?
All of the technologies and challenges discussed throughout this website with regards to providing reliable power to health clinics also apply to blood banks. These may include battery banks and inverter systems to provide power in times of blackouts and back up generation from diesel generators, solar panels or some combination of these technologies. Many countries have stand alone blood banks with a medium size load, making them an attractive candidates for on site renewable energy systems in cases where the grid power is non-existent or particularly unreliable.
What are the energy requirements of blood banks?
The energy requirement of a sample blood bank load is shown below. This particular facility was in Haiti, but it provides one example of the loads of typical equipment found in a blood bank:

What are some special considerations for blood banks?
As can be seen by the example blood bank load chart, the majority of the blood bank electrical load comes from refrigeration and air conditioning. Care should be taken to ensure that energy efficient, and properly sized refrigerators are used for each facility (see Refrigeration). Gas/electric hybrid refrigerators should be considered for facilities with intermittent power supplies. Air conditioning should only be used if absolutely required, and should not be connected to any battery back-up systems.
