Electric kettles are another common example. Once the water has boiled, most modern kettles automatically switch off, but that feature does not make every electrical fault impossible. Place the kettle on a stable, dry surface, keep water away from the electrical base, and avoid using it if the cord, plug, or housing is damaged. Whether you unplug it after use depends on its design and the manufacturer's recommendations.
Coffee makers vary considerably. A basic machine may have a simple on-off switch, while another model may include a timer, warming plate, or programmable functions. A warming plate can remain hot after brewing, so it is important to follow the manufacturer's instructions and turn the machine off when appropriate. If the device has no need to remain connected, unplugging it after use may be a reasonable precaution.
Air fryers, electric grills, sandwich makers, and similar countertop cooking appliances also deserve attention. They can reach high temperatures and need adequate space for ventilation. Switch them off after cooking, allow them to cool as instructed, and keep them away from curtains, paper towels, packaging, and other combustible materials. Do not cover ventilation openings or operate an appliance on a surface that the manufacturer has not approved.
Rice cookers and multicookers require a little more judgment. Some models have a warming function that is intended to operate for a limited period after cooking. Others may have programmable features or specific instructions about how long food can safely remain warm. Do not automatically unplug a device in the middle of a cooking cycle or while it is performing a function that the manufacturer says must be completed. Instead, plan cooking so that the appliance is used as intended, then switch it off or disconnect it when appropriate.
Refrigerators and freezers are different. They need a continuous power supply to keep food at safe temperatures. Unplugging them every night would be counterproductive and could lead to food spoilage. Similarly, some built-in appliances, ventilation systems, and other equipment may be designed to remain connected. Always distinguish between a small appliance that is idle and a device that must operate continuously.
Phone chargers, battery chargers, and other small electrical accessories should also be checked for damage and excessive heat. Use products that are appropriate for the device, keep them away from flammable materials, and replace equipment with cracked housings or frayed cables. A charger that repeatedly becomes unusually hot, smells burnt, or makes abnormal sounds should be taken out of service.

A useful way to decide what to do is to ask three questions:
-
Has the appliance finished its task?
-
Does the manufacturer recommend switching it off or unplugging it after use?
-
Is the plug, cord, outlet, and appliance in good condition?
If the answer suggests that the device should be disconnected, switch it off first and unplug it safely by holding the plug rather than pulling the cord. Never touch a plug or socket with wet hands.
The goal is not to disconnect everything indiscriminately. It is to identify equipment that does not need to remain powered and ensure it is used safely. A clear understanding of each appliance's function makes a bedtime check more effective and less likely to interfere with essential household equipment.
Chapter 3: Warning Signs of a Dangerous Plug or Electrical Outlet
An appliance does not have to be visibly burning to present an electrical hazard. In some cases, the first warning is subtle: a plug feels hotter than expected, a socket becomes discolored, or a faint burning smell appears when a device is operating. Recognizing these signs early can help prevent a small problem from escalating.
One warning sign is unusual heat around a plug, socket, or power strip. Electrical equipment may become slightly warm during normal operation, depending on the device and the amount of power it uses. However, a plug or outlet that becomes excessively hot, especially when paired with discoloration, a smell, or intermittent power, should be treated as a potential fault.
