Investigate the power cord of your air conditioning system immediately. Overlooked errors might lead to a house fire.
In response to a surge in electrical fires across South Korea, particularly during the current heat wave, authorities are urging citizens to exercise caution when using power strips and extension cords, especially with air conditioners.
Recent investigations have revealed that two separate apartment fires in Busan, on July 2 in Gijang County and June 23 in the Busanjin District, may have been caused by electrical issues related to power strips. The power strip used in the July 2 fire was connected to both a standing air conditioner and its outdoor unit, potentially overloading the circuit and leading to overheating.
The Korea Consumer Agency has advised against overloading power strips with multiple devices at once, and instead recommends using wall outlets for large appliances like air conditioners. The Agency also warns against daisy-chaining extension cords by plugging one strip into another, as this increases resistance and heat buildup, creating a fire hazard.
Busan's fire data shows that from 2020 to 2024, nearly 30 percent of residential fires in the city were caused by electrical issues. This trend has prompted the National Fire Agency to issue a national fire risk advisory last Friday, citing increased fire activity linked to surging electricity demand during the heat wave.
Fire safety experts believe these recent apartment fires in Busan were preventable. To prevent electrical fires caused by misused power strips or extension cords—especially when using air conditioners during heatwaves—follow these key safety practices:
1. **Avoid Overloading Circuits and Power Strips**: Air conditioners consume a significant amount of power. Plugging them into power strips or extension cords that are not rated for their high current draw can cause overheating and fires. Always plug air conditioners directly into a properly grounded wall outlet designed to handle their load.
2. **Use Extension Cords Properly and Temporarily**: If you must use an extension cord, ensure it is heavy-duty and rated for the air conditioner’s power requirements. Use cords only as a temporary solution, not as permanent wiring. Fully uncoil extension cords to prevent heat buildup, and never run them under rugs or carpets where heat can be trapped.
3. **Inspect Cords and Outlets Regularly**: Check for exposed wires, frayed cords, or damaged outlets. Faulty wiring or damaged insulation can lead to arcing faults, which generate heat and may ignite a fire.
4. **Install Safety Devices**: Install arc fault circuit interrupters (AFCIs) in your home’s electrical panel. AFCIs detect arcing faults and shut off power before a fire can start. Also, ensure smoke detectors are installed and functioning on every level of your home, as early detection of smoke is critical.
5. **Maintain Good Air Conditioner Usage Practices**: During heatwaves, avoid running multiple high-power devices on the same circuit as your air conditioner. Allow proper ventilation around the unit to prevent overheating, and schedule regular professional maintenance to ensure the air conditioner works efficiently without electrical faults.
By following these guidelines, you can significantly reduce the risk of electrical fires related to power strips, extension cords, and air conditioner use during periods of high heat. The Busan Fire Department will conduct a live fire safety test on Thursday to demonstrate the ease with which faulty or overloaded power strips can ignite. It is crucial to replace cords that are frayed, damaged, or overheating, and to never plug an air conditioner into a power strip.
The surge in electrical fires across South Korea, particularly during the current heat wave, highlights the importance of science and health-and-wellness in understanding and preventing such incidents. For instance, recent investigations into apartment fires in Busan reveal that overloading power strips and misusing extension cords can lead to electrical issues and fire hazards, particularly when using air conditioners.
