A recommended safety precaution when working with electricity is always turning off the power source before handling electrical components. This practice helps prevent electric shock and other accidents by ensuring that circuits are de-energized before any work is performed. Additionally, using insulated tools and equipment further reduces the risk of electric shock.

Regular inspection of electrical appliances is essential to identify and replace damaged cords, plugs, or switches promptly. By conducting routine inspections, individuals can prevent potential hazards such as electric shock or fire caused by faulty components. This proactive approach to maintenance ensures that appliances remain safe and functional for use.

The primary purpose of using insulated tools and equipment when working with electricity is to avoid electric shock. Insulated tools have handles or coatings that prevent the conduction of electricity, reducing the risk of injury to the user. By using insulated tools and equipment, individuals can safely handle electrical tasks without the danger of electric shock.

The primary reason for using ground fault circuit interrupters (GFCIs) is to prevent electrical hazards in areas where water is present. GFCIs detect imbalances in electrical currents and quickly shut off power to prevent electric shock. This feature is especially crucial in bathrooms, kitchens, and outdoor areas where the risk of water-related accidents is higher.

A recommended practice for handling electrical cords is to keep them away from heat sources and water. Heat can damage the insulation of the cords, increasing the risk of electric shock or fire. Similarly, water can cause short circuits or electric shock if it comes into contact with exposed wires. Keeping cords safely away from these hazards ensures their longevity and safety.
