1 - What is Insulated security Footwear?

Insulating safety and security footwear, additionally called dielectric footwear, type part that the an individual Protective equipment (PPE) arsenal worn by a user come minimise the threat to life brought about from dangerous high voltage shocks and other perils within a workshop atmosphere such as slips and heavy objects falling on to the foot. Insulated safety and security footwear consists of an electrically insulated sole and other safety features such as protective toes caps. Their key purpose is come protect versus and protect against an electric current from gift grounded. High voltage electric present can protect against the love or develop fatal burns to an unprotected user. PPE is often the last line of defence for electric professionals or designers working on one of two people live or freshly switched turn off systems. Insulated footwear is commonly available in either boots or shoes styles, with different safety ratings dependant on particular product specification.

Vehicle Technicians working on electrical Vehicles (EV) or plug in Hybrid electric Vehicles (PHEV) are compelled to wear Insulated security Footwear as result of the voltages existing in the vehicles battery packs. Modern vehicles attribute a range of various battery packs, and also the voltages deserve to be anywhere in between 300V and also 900V. Course 0 insulated safety and security footwear is an ideal for trained technicians performing maintenance and also diagnostics ~ above EVs.


Insulating footwear is offered by many individuals across many industries. Whether it’s installation, maintenance or removed of electric systems, footwear is crucial an essential aspect of PPE that must be adhered to. The is necessary to mental dielectric footwear or insulating footwear have to not be used rather of other PPE, however as secondary protective item.

For functioning on EV and PHEV"s insulated footwear should be worn when:

First making the car battery fill safe;Conducting tests come ensure the generator/ battery is isolated;Working ~ above the battery pack or HV system;Reconnecting the battery pack to the vehicle;Conducting diagnostics of the HV system and also connections.

3 - Insulated security Footwear Ratings and also Safety Guide

Electrically insulating footwear is experiment at the proper leakage current test voltage for their class rating, (see table below), for 3 minutes throughout which the leakage existing must not exceed the maximum allowed value for the course rating. Because that initial certification that a product, the shoe/ boots is experiment to the withstand test voltage, but this is taken into consideration a damaging test.

As insulated safety footwear is likewise classed as safety footwear they will likewise meet the forced standards the EN ISO 20345:2011. These standardswill incorporate such things as on slide resistance, toe protection, resistance to chemistry etc.

Warwick Test offers recommends class 0 rated footwear because that PHEV and EV vehicle maintenance and diagnostics.

Obsolescence Period

Typically, the final obsolescence date of insulated footwear is 3 year from the day of marking presented on the shoe.

6 - EV Diagnostic Technician Footwear - Summary

Diagnostics and repair the EV and also PHEV vehicles will constantly be linked with an electric safety risk, together energised circuits pose danger to life from electrical shocks. Her footwear might be the last line of defence in between you and also a fatal electrical shock from the vehicles battery pack. Yet It"s vital to psychic insulated safety footwear is only part of the PPE list that should be worn as soon as conducting job-related on battery packs whilst keeping or repairing EV/PHEV vehicles.

Electrically insulated footwear is obtainable in a number "Classes" dependant ~ above the level of voltage they space designed to defend against. The ideal Class of insulated footwear for working on EV/PHEV is class 0.
