Are there requirements for the periodic re-testing of insulated hand tools?
A. There are not specific requirements for re-testing insulated hand tools, but in compliance with 29 CFR 1910.355(a)(1)(ii), “protective equipment shall be maintained in a safe, reliable condition and shall be periodically inspected or tested as required by 1910.137”. Most manufacturers recommend inspecting the insulation before each use and having a qualified person perform an inspection and certification annually. To assist the inspection process, some manufacturers provide two-layer insulation that changes color when the insulation has been worn. Q. Can insulated tools be used on energized circuits? A. Always follow the manufacturer’s guidelines for use. Although insulated tools may be tested and certified to 1000 volts AC, the testing agencies do not recommend using them directly on energized circuits. Most insulating tools are only intended for protection from accidental contact with energized circuits. Sources for More Information 29 CFR 1910.335 29 CFR 1910.
