Consider hooking up a remote temperature monitoring system that can alert you to temperature excursions for any reason, like a refrigerator door being left open or an equipment malfunction. Monitoring systems can be setup through certain office alarm systems or purchased independently. Two companies who specialize in this area (Temperature Guard and Sensaphone) make systems that can monitor multiple storage units and call or text several phone numbers until there is a response. The ability to monitor your vaccine storage equipment while you are away from the office is not only an investment in protecting your vaccines, it is also an investment in your peace of mind!
