OSHA says one of these professional lighting instrument AC power plugs is potentially hazardous. Which one?

Question

Quizplus · Accepted Answer

A three-prong plug and a grounded plug are essentially the same, both including a ground connection. However, the question implies a distinction, suggesting a potential misunderstanding in the options provided. Typically, both three-prong (grounded) plugs and twist-lock plugs are considered safer options compared to two-prong, ungrounded plugs. Twist-lock plugs offer an additional safety feature by locking the connection to prevent accidental disconnection, which is particularly useful in professional settings where vibrations or movements might otherwise disconnect the plug. Given the options and the usual safety standards, none of the listed plug types are inherently hazardous; all are designed to enhance safety. The question might be based on a misunderstanding or a specific context not provided.
