Conductive material such as steel tape measure, wire, wet or non-rated rope, or linen tape-line containing metallic reinforcement can be used around energized wire, apparatus, equipment, or third rail. True or False?

• A. True
• B. Sometimes
• C. Not applicable
• D. False

Answer: (D)

When working around energized wires or third rails, anything that can conduct electricity can create a hazard. The materials listed—steel tape measures, wires, wet or non-rated rope, and linen tape-line with metallic reinforcement—can form a conductive path to you or to ground. Wet rope conducts even more readily, and any metallic content can bridge to live parts. Because of that, using these around energized equipment risks shock, short circuits, or arc flash.

The safe practice is to use nonconductive or properly rated insulated tools and equipment, and to ensure the circuit is de-energized or appropriately safeguarded before you work. In short: these materials should not be used around energized lines, so the statement is false.
