A newly appointed immunisation officer at a district hospital in Uttar Pradesh is reviewing the cold chain infrastructure. The vaccine storage room currently uses a standard domestic refrigerator (2–8°C) for storing vaccines. During a power outage lasting 4 hours on a hot summer day, the temperature inside the refrigerator rose to 18°C. The officer discovers that there is no backup power supply, no ice-lined refrigerator, and no vaccine vial monitors on any of the stored vaccines. The hospital is located in a region with frequent power cuts. What is the most appropriate immediate action?
