The article discusses the safety of household appliances when left plugged in, particularly focusing on the risks associated with certain devices. According to Jerry Poon, an electrical engineer, it’s important to unplug devices that generate heat, draw significant power, or have faulty cords.
Here are the key appliances to unplug when not in use:
- Space Heaters: High fire risk if mishandled. Avoid using them on rugs or with extension cords.
- Air Fryers: Should be treated like space heaters. They can draw power even when turned off, posing safety risks.
- Portable AC Units: Classified as high-power devices, necessitating they be unplugged.
- Hair Tools: Hair dryers and curling wands can fail, creating hazards if left plugged in.
- Old Coffee Makers: Older models lack automatic shut-off features and should always be unplugged after use.
- Lamps and Old Cords: Old cords are potential fire hazards and should be replaced.
- Toasters: Though the fire risk is lower, they should still be unplugged to avoid possible short circuits.
In contrast, low-power devices like phone chargers and alarm clocks are generally safe to leave plugged in as long as cords and outlets are in good condition. The article emphasizes general safety practices for household appliances.
