What is a necessary precaution when working near electrical installations in elevators?

1. Using rubber gloves

2. Keeping the work area dry

3. Using insulated tools

4. Turning off all lights

The correct answer is: Using insulated tools

Using insulated tools is essential when working near electrical installations in elevators because these tools are specifically designed to prevent electrical shock. They are made from materials that provide a barrier to electrical currents, which significantly reduces the risk of accidental contact with live components. In environments like elevators, where there are potentially exposed wires and electrical connections, utilizing insulated tools ensures that a technician can perform their work safely. While using rubber gloves and keeping the work area dry are also important safety measures, they serve as supplementary precautions rather than primary protections against electrical hazards associated directly with tools. Turning off all lights, though a good practice for visibility and safety, does not specifically address the risk of electric shock that can occur during maintenance or repair tasks. Therefore, the use of insulated tools stands out as a necessary precaution that directly contributes to the safety of personnel working with electrical components.
