Every insulated hand tool is rated for exposure up to 1,000 VAC and dielectrically tested at 10,000 VAC. These electrical tools meet or exceed current ASTM F1505-07 and IEC 900 Standards for Insulated Hand Tools. These tools will help you to be compliant with OSHA 29 CFR 1910 Subpart S and NFPA 70E.
These electrician tools use insulating material used is impact resistant and flame retardant. The two-color insulation makes inspection easier which adds to the overall safety. If the yellow under laying is showing, the tool may no longer be insulated properly and should be considered for electrical retesting.
