What is an important safety measure to take when using extension cords during drying?

When using extension cords during drying, it is crucial to ensure that they contain a ground conductor and are UL certified. This safety measure is important because a ground conductor helps prevent electrical shock by providing a safe pathway for current to flow in case of a fault, thus protecting both the user and the equipment. UL certification indicates that the cord has passed rigorous safety tests and meets specific safety standards, reducing the risk of electrical hazards, such as overheating and short circuits, which can be exacerbated in wet or humid environments typical of drying processes.

While it is necessary for extension cords to be long enough to reach power outlets and to manage outlets effectively, these factors alone do not address the safety concerns associated with electrical equipment in moisture-laden environments. Similarly, keeping cords away from water sources is vital but does not replace the need for proper grounding and certification, which comprehensively contribute to electrical safety.
