description: This is a must-see video if you have questions about the APRU alarms, why blood banks require the APRU to have alarms, and how to silence them in stealth operations. Blood refrigerators typically have alarms to ensure the blood's safety and quality. The alarms are designed to alert staff when there is an issue with the fridge, such as a temperature deviation or power outage, which could potentially compromise the integrity of the blood.
