Electricity & EquipmentQuestion 409 of 484
When unplugging a hair dryer from the wall, the correct method is to:
a.Grasp the molded plug body and pull straight out, never the cord
b.Leave it plugged and switch off the dryer's own power button
c.Twist the plug 90 degrees and then pull
d.Yank the cord sharply with one quick motion
Explanation
Pulling on the cord rather than the plug stresses the wire-to-prong solder joints inside the plug, eventually loosening them. Loose internal connections create arcing, overheating, and the kind of brittle, cracked plug that ignites lint. The correct technique is to grasp the molded plug body and pull straight out, perpendicular to the wall. California licensees are required to keep equipment in safe condition under CCR Title 16 §979.2, and cord care is part of that duty. Option A guarantees cord damage. Option C wrenches the prongs and damages the outlet. Option D leaves the device energized at the cord and plug, which is unsafe storage.
