What safety equipment is essential when working on electrical installations?

When working on electrical installations, safety equipment plays a crucial role in protecting workers from potential hazards. The inclusion of insulated tools, rubber gloves, and safety goggles in the correct answer signifies the importance of a comprehensive approach to safety.

Insulated tools are specifically designed to prevent electric shock by providing a protective barrier between the tool and any live electrical parts. This insulation is essential when handling wiring and connections that may be energized.

Rubber gloves are critical as they are designed to protect the user from electric shock, especially when working on or near live circuits. These gloves are specifically tested to withstand high voltages, providing an additional layer of safety to the user.

Safety goggles are also important as they protect the eyes from debris and sparks that can occur during electrical work. The risk of injury from flying particles is always present, and goggles help ensure that workers can see clearly while protecting their eyesight.

The combination of all these safety measures reinforces the principle that comprehensive protection is necessary when working with electricity, making the answer that includes all the equipment essential for ensuring a safer work environment.
