Which item should be used to help with electrical safety in a workspace?

Three-pronged plugs are essential for ensuring electrical safety in a workspace because they provide a grounded connection. The grounding pin of the plug connects to the ground wire in the electrical system, which helps to prevent electrical shock and reduce the risk of electrical fires. This grounding feature helps in safely redirecting any stray current, thus protecting both equipment and individuals from potential hazards.

Using three-pronged plugs ensures that electrical appliances are correctly and safely connected to the power source, enhancing overall safety in the environment. This is particularly important in a workspace where there may be multiple devices in use, and maintaining safe electrical practices is crucial to preventing injuries or accidents related to electricity.

In contrast, two-pronged outlets do not provide the same level of safety as they lack the grounding feature. Extension cords can be useful, but if not used properly, they can be a source of electrical hazards, especially when overloaded. Circuit breakers are essential safety devices that can help protect against electrical overloads by shutting off power, but they do not directly assist in the safe connection of devices to the electrical supply as effectively as three-pronged plugs do.
