Insulated tools are specially designed hand tools that have protective coatings to prevent electrical shock. These tools are essential for electricians and other professionals who work with or near live electrical circuits. The insulation helps to safeguard users from accidental contact with high voltage. Typically made from materials like rubber or plastic, insulated tools are tested to meet specific safety standards. Common types include screwdrivers, pliers, and wrenches. Using insulated tools reduces the risk of injury and enhances safety in environments where electricity is present, making them a crucial part of any electrician's toolkit.
