What is the primary advantage of using insulated tools?

The primary advantage of using insulated tools is that they provide protection against electrical shocks. Insulated tools are designed with materials that prevent electrical current from passing through the tool and into the user. This is especially important for outside linemen who often work with high-voltage equipment and overhead power lines. The insulation serves as a barrier, reducing the risk of severe injuries or fatalities from accidental contact with live electrical components.

Using insulated tools is a critical safety measure in preventing electrical incidents, making them essential in the toolshed of any lineman. While other factors like weight or cost might be of interest, the fundamental purpose of insulation is to enhance user safety in hazardous electrical environments.
