What type of tape measure is prohibited on or near energized equipment or lines?

A metal tape measure is prohibited on or near energized equipment or lines primarily due to the conductive properties of metal. When working in proximity to energized lines, using a metal tape measure poses significant risks, including the potential for electrical shock or short circuits, as metal can conduct electricity. This makes it particularly hazardous when there is a possibility of contact with live electrical components.

In contrast, other types of tape measures, such as plastic, wooden, and cloth, do not possess the same level of conductivity and are generally considered safer alternatives when working around electricity. They minimize the risk of accidents that can arise from unintentional contact with energized parts. Therefore, understanding the properties of different materials is crucial for ensuring safety in environments where electricity is present.
