When operating at voltages above 1000 V, which tool rules apply for contacting live parts?

• A. Use insulated tools and hot-sticking, following clearance rules; no bare-handed contact
• B. No special rules beyond standard PPE
• C. Tools must be non-insulated
• D. Use bare-handed contact with gloves

Answer: (A)

When working on equipment at voltages above 1000 V, you must keep contact with live parts through protective insulation and remote handling. Insulated tools are rated for the voltage in question and, together with a hot-stick or similar device, let you manipulate switches or insert or remove parts without your body or hands approaching the energized surface. Following clearance rules ensures you maintain safe distances and avoid arcing or unintended contact.

Relying on standard PPE alone isn’t enough because it doesn’t provide a continuous dielectric barrier at the point of contact, and gloves or clothing can’t guarantee safety against high-Voltage arcs or tracking. Bare-handed contact is not allowed at these levels, and non-insulated tools would become conducting paths, creating a serious shock and arc risk. Insulated tools plus hot-sticking, with the proper clearances, is the proper approach.
