Why is it important to avoid using metal tools when working on electrical systems?

Using metal tools when working on electrical systems poses a significant risk due to their ability to conduct electricity. If a metal tool makes contact with an electrical component or circuit while the system is energized, it can create a path for electrical current to flow where it shouldn't, potentially resulting in short circuits, equipment damage, or even severe electric shock to the technician. This is particularly crucial when dealing with high-voltage systems or sensitive electronic components, where the risk of unintended contact is heightened.

In contrast, tools designed specifically for working on electrical systems often have insulating features or are made from materials that do not conduct electricity. This insulation helps to safeguard the technician from accidental shocks and enhances overall safety while performing electrical repairs or diagnostics. Being aware of the potential hazards associated with conducting materials emphasizes the need for careful tool selection in automotive electrical work.
