Bangkok: MEA advises on the correct use of extension cords, emphasizing the importance of checking for the Thai Industrial Standards Institute (TIS) mark to prevent short circuits and reduce the risk of fire. The Metropolitan Electricity Authority (MEA) has issued detailed guidelines aimed at enhancing safety in the use of extension cords and power strips, highlighting the potential dangers if not used correctly.
According to Thai News Agency, MEA underscores the necessity of selecting equipment that complies with safety standards, specifically TIS 2432-2555. The authority stresses that extension cords must bear the TIS mark, feature an overcurrent protection system, and be constructed from flame-retardant materials to mitigate risks associated with electrical fires.
The MEA further advises that all electrical outlets and plugs should be three-pronged, incorporating a grounding connection to prevent electrical leakage. It is recommended that the outer casing of extension cords be made from high-quality, heat-resistant, and non-flammable materials such as standard ABS or PC plastic.
The authority cautions against plugging multiple high-power appliances into a single power strip, as this can lead to electrical overload and potentially cause overheating. Additionally, connecting extension cords in a series, known as "daisy-chaining," is discouraged due to the risk of electrical overload and subsequent overheating.
Using extension cords in damp areas, near water sources, or in confined spaces where heat cannot dissipate effectively should be avoided. The MEA advises that appliances should be switched off and unplugged from the main outlet when not in use to minimize risk.
Regular checks of power cords and sockets are recommended to ensure their condition is safe for continued use. Warning signs such as damaged wires, cracked insulation, loose plugs, hot surfaces, or burning smells should prompt immediate discontinuation of use and disconnection from the power supply to prevent accidents and potential fires.
