# Electrical safety warnings for household appliances > Live situation record from CLSTR: https://clstr.news/situations/electrical-safety-warnings-for-household-appliances > Updated: 2026-10-15T13:50:51.000Z. Sources: 20. Developments: 6. Electrical experts and electricians continue to issue warnings regarding the risks of using power strips and extension cords for high-consumption household appliances. The primary concerns include overheating, electrical damage, blown fuses, and potential fires. Specific high-risk categories include refrigerators and freezers, kitchen appliances like microwave ovens, toasters, and coffee makers, heating and cooling units, and personal care items like hair dryers. Recent guidance has expanded to include technical requirements for specific environments. For outdoor use, such as powering lawnmowers or pressure washers, extension cords must be designed to withstand moisture, dirt, and temperature fluctuations. Experts emphasize matching equipment to environmental conditions, noting that factors like cable length, cross-section to prevent voltage drops, and appropriate IP ratings (such as IP44) are essential for protection against water splashes. To prevent fire hazards, experts reiterate that high-power devices—including electric heaters, kettles, washing machines, microwave ovens, electric ovens, portable heating plates, and irons—should be plugged directly into wall sockets. Warning signs of imminent danger include overheating plugs, discoloration of plastic, burning smells, or crackling sounds. In the event of smoke or sparking, users are advised to turn off the circuit breaker at the distribution board rather than touching damaged components. Energy expert Gordon Wallis from Your NRG has also warned against “daisy-chaining,” the practice of plugging one extension cord into another, which can lead to overheating, sparking, and electrical failure. ## Claims - Extension cords are designed for temporary use with low energy consumption. (corroborated by 2 sources) - Daisy-chaining extension cords increases the risk of overload and failure. (corroborated by 2 sources) - Air fryers can consume up to 2000 W. (corroborated by 2 sources) - Toasters consume between 1200 and 1400 W. (corroborated by 2 sources) - Refrigerators consume between 300 and 800 W. (corroborated by 2 sources) - Microwave ovens can cause sudden power surges that extension cords may not handle. (corroborated by 2 sources) - Electric ovens and stoves require a dedicated electrical circuit. (corroborated by 2 sources) - Extension cords are designed for temporary use with low energy consumption, not as permanent solutions for high-power consumers. (corroborated by 2 sources) - Daisy-chaining extension cords by plugging one into another significantly increases the risk of overloading, sparking, and fire. (corroborated by 2 sources) - Air fryers can consume up to 2000 W and should be plugged directly into wall outlets. (corroborated by 2 sources) - Toasters consume between 1200 and 1400 W, which can cause overheating on extension cords. (corroborated by 2 sources) - Refrigerators consume between 300 and 800 W and are not intended for the continuous load of extension cords.
