What should be checked prior to using insulated tools near live parts?

• A. The color of the insulation
• B. For any damage or wear to insulation
• C. Whether the tool is new
• D. The brand

Answer: (B)

Insulation integrity is what protects you when working near live parts. Before using insulated tools, you must inspect the tool’s insulation for any damage or wear because even small nicks, cuts, cracks, gouges, burns, or moisture can reduce its dielectric strength and create a path for current if you come into contact with a live conductor. If you find any damage, remove the tool from service and replace or re-certify it as required.

Color, whether the tool is new, or the brand do not guarantee protection. Color can be unrelated to actual insulation condition, newness doesn’t guarantee it’s free of manufacturing flaws, and brand does not affect the tool’s electrical safety. The crucial check is the physical condition of the insulation.
