Types of Insulated Hand Tools

Insulated hand tools are used for operations performed under live voltage and are available in many product types, such as Hex Keys, Nut Drivers, Pliers, Ratchets & Accessories, Screwdrivers, Sockets, Tool Sets and Wrenches.


Application fields include, but are not limited to, Electrical Installation, Power Plants, Electrical Stations & Substations, High Voltage Networks, Low Voltage Networks, Telecommunications, Chemical Industry, Fire-Fighters and Lighting Installation and Repair.


All insulated hand tools are required to meet International Electrotechnical Commission (IEC) 60900 1000 volt rating system and American Society for Testing and Materials (ASTM International) i.e., F1505-01 standards. For tracking purposes, approval markings such as, manufacturer name, part number and date, and voltage, are included on every tool. Manufacturers are responsible for testing and certifying each tool individually to ensure that they are suitable for specific working conditions. Generally, the maximum rated voltage for insulated tools is 1000 volts AC and 1500 volts DC. Operators must have current certification from an official organization and use insulated accessories such as gloves, mats and safety glasses.

Since operations performed under live voltage are becoming more common, so too are industry requirements and on-the job safety precautions. In an effort to reduce the number of fatalities and injuries, new regulations have been published by OSHA (29 CFR 1910.335(a) (2) (i)) requiring the use of insulated tools when working near energized circuits.

Safety Tips

  • Wear insulated gloves, eye protection and other personal protective equipment if necessary
  • Keep tools clean and dry
  • Check insulation is sound before using a tool
  • Never use a tool with insulation that is cracked, cut, perforated or damaged
  • Don't modify insulation
  • Don't let others use your insulated tools
  • Always use the correct tool
  • Check standards and approval markings
  • Have a qualified person inspect and re-certify tools annually for safe use

This list is not all inclusive. Reference and read manufacturer's safety recommendations and keep the instructions.
