Web alarm clock for 5:04 p.m.
As you hand over the refrigerator check after a power surge, set the 5:04 pm alarm so the next person knows exactly when to inspect it. That keeps the responsibility clear during a shift change and leaves time to note anything unusual before 6:00 pm. Tell the person taking over what to examine, especially whether the interior light, cooling sound, and stored food seem normal.
Your refrigerator check can be missed if the alarm sound has quietly switched to connected headphones. Before leaving the task with someone else, confirm where the audio will play and choose a volume they can hear from the kitchen or stockroom. Keep this browser page active and the phone or computer awake: if either is shut down, the refrigerator reminder will not sound, so the handover could be overlooked.
By 5:04 pm, traffic, customers, children arriving home, or preparations for the evening meal can make the surroundings noticeably louder. Put the phone near the person responsible, away from running fans or appliances, and use vibration as an extra cue if available. If the area usually becomes quieter toward 6:00 pm, agree that any alarm heard then means the refrigerator still needs a recorded check.
