New NFPA 70E Requirements for Insulated Hand Tools

Insulated hand tools are used for safety. NFPA 70E is the "Standard for Electrical Safety in the Workplace". This was revised effective January 2009 for insulated hand tools in section 130.7(D)(1)(a)(3).

The overall requirements for where to use insulated tools didn't change. If there is any chance that a tool could make accidental contact when working close to energized parts, insulated tools are required. In addition, insulated hand tools are required where specified in Table 130.7(C)(9).


The new requirement is for the electrician to inspect his insulated tool prior to each use. This required inspection looks for damage in the outer protective coating, which covers the inner insulation. The different layers have contrasting colors to easily spot any damage. Also the user should be checking whether the insulated tool meets the OSHA safety standards.

This new requirement emphasizes that electricians should be taking the responsibility to check their own tools. What's the difference between a hardware store orange screwdriver marked "Insulated" and an insulated screwdriver complying with OSHA and NFPA 70E - besides the price? The answer is safety and OSHA compliance.

UL has an insulated tool standard that includes all the OSHA and NPFA 70E requirements. If the insulated tool is UL listed for the voltage, it's safe to use.
