The key to avoiding electric shock in a barbering setting is ensuring that all tools are properly grounded and dry. Proper grounding of electrical equipment helps to prevent any electrical faults from causing shocks to the user or clients. When tools are grounded, any excess electricity can safely flow directly to the ground, minimizing the risk of a shock.

Additionally, maintaining tools in a dry state is crucial because moisture can significantly increase the risk of electric shock. Wet conditions enhance conductivity, making it easier for electric current to pass through a person's body if there is a fault in the appliance being used. Therefore, barbers must regularly check their tools to ensure they are dry and well-maintained to uphold safety standards while providing services.

The other options do not primarily address both aspects of electric safety: grounding and moisture control. For instance, while using cords with multiple prongs may seem safer, it does not ensure grounding if the tools themselves are not properly maintained. Insulated tools also contribute to safety but are not a substitute for ensuring that all equipment is dry and grounded appropriately. Keeping tools plugged in at all times is unsafe and poses a higher risk of electric shock.
