What tool is often used to ensure the safety of electrical systems during maintenance?

The Lock Out / Tag Out (LOTO) procedure is a critical safety practice used to ensure that electrical systems are properly shut down and unable to be accidentally restarted during maintenance or servicing. This method includes physically locking and tagging equipment to prevent the inadvertent energization of the system while work is being carried out.

Using LOTO helps protect technicians from electrical hazards by ensuring that they are aware of the potential dangers and that other individuals cannot inadvertently turn on the power while maintenance is ongoing. It is a standard safety measure in many industries, especially when dealing with high-voltage systems or complex machinery.

While other tools like insulation testers, voltage meters, and multimeters serve important roles in testing and diagnosing electrical circuits, they do not provide the direct safety measures that LOTO does. These tools are essential for measuring electrical parameters and checking the integrity of electrical components, but they do not prevent electrical hazards during maintenance work. In contrast, Lock Out / Tag Out directly addresses safety protocols to mitigate risks associated with maintenance tasks.
