List which loads are essential for the crop and which can wait during a power interruption. Have an engineer check the electrical supply, starting loads, protection and backup arrangement for the actual equipment. Room volume alone does not determine cooling capacity: outside conditions, building heat gain, fresh air, crop heat and operating schedule also matter.
Practise the reporting and recovery procedure with trained staff. Identify who receives an alarm, who checks the crop and who may work on equipment. After a failure, preserve the event history and inspect the affected crop locations. Restarting the machine does not prove the crop has already recovered.
