During an outage, it is useful to disconnect sensitive electronics and appliances that could restart unexpectedly when power returns. Refrigerators and freezers are normally left closed and connected so they resume operation, while televisions, computers, tools, and space heaters can be safely unplugged or switched off.
Unplug sensitive electronics when it is safe to do so
Computers, televisions, game systems, and audio equipment can be unplugged to reduce exposure to power fluctuations when service returns. Do so only at dry, accessible plugs without handling damaged wiring or panels.
Switch off heat-producing or motorized appliances
Space heaters, electric ranges, irons, tools, and equipment that could start automatically should be switched off. This prevents unsupervised operation if electricity returns while you are away.
Keep the refrigerator and freezer closed
Opening doors speeds warming. Leave them connected unless there is a local electrical hazard so they can resume cooling when service returns without relying on someone to remember to plug them back in.
Leave one light on as a power-restoration indicator
A simple lamp can indicate when power returns while other loads stay off. If there are sparks, burning odors, downed wires, or water near electrical equipment, do not restore appliances and contact the utility or emergency services.
