If a worker does not utilize insulation rated for the present voltage, what risk does this pose?

Choosing insulation rated for the present voltage is crucial for ensuring safety in electrical work. If a worker uses insulation that does not meet the necessary voltage rating, it can lead to increased shock hazards. This is because inadequate insulation may not effectively isolate the worker from live electrical components, increasing the likelihood of electrical shock. The risk is particularly significant in high-voltage environments where the potential for severe injury or fatality from electric shock is heightened. Proper insulation is designed to withstand specific voltage levels; if the rating is insufficient, the material could break down, ultimately allowing electrical currents to escape the intended path and potentially harm the worker. Therefore, using the correct insulation plays a vital role in maintaining a safe working environment and minimizing electrical hazards.
