To safely handle electrical tools, they should always be?

To safely handle electrical tools, grounding and insulation are crucial features. Grounding provides a path for stray electricity to safely dissipate into the ground, reducing the risk of electric shock. Insulation, on the other hand, prevents accidental contact with live wires or components, protecting the user from electrical hazards.

When tools are grounded and insulated, they help ensure that the user remains safe while operating the equipment. This is particularly important in environments where moisture or conductive materials are present, as such conditions can elevate the risk of electrical shock. Proper grounding and insulation work together to create a barrier between the user and the electric current, significantly enhancing safety during use.
