1 - What is Insulated safety Footwear?

Insulating safety footwear, also called dielectric footwear, form part that the an individual Protective devices (PPE) armoury worn through a user come minimise the danger to life resulted in from dangerous high voltage shocks and other hazards within a workshop atmosphere such together slips and also heavy objects falling on come the foot. Insulated safety footwear consists of an electrically insulated sole and other safety features such together protective toes caps. Their key purpose is come protect against and prevent an electric present from gift grounded. High voltage electric current can stop the heart or produce fatal burns come an unprotected user. PPE is frequently the last heat of defence for electrical professionals or engineers working on either live or freshly switched turn off systems. Insulated footwear is commonly available in either boot or shoe styles, with different safety ratings dependant on details product specification.

Vehicle Technicians functioning on electric Vehicles (EV) or plugin Hybrid electric Vehicles (PHEV) are forced to undertake Insulated security Footwear because of the voltages existing in the vehicles battery packs. Modern-day vehicles feature a range of various battery packs, and the voltages have the right to be anywhere between 300V and also 900V. Class 0 insulated safety and security footwear is an ideal for trained technicians performing maintenance and also diagnostics on EVs.


Insulating footwear is provided by plenty of individuals throughout many industries. Even if it is it’s installation, maintain or removed of electrical systems, footwear is crucial an essential element of PPE that have to be adhered to. That is crucial to mental dielectric footwear or insulating footwear should not be used instead of various other PPE, however as secondary protective item.

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

First making the auto battery pack safe;Conducting tests to ensure the generator/ battery is isolated;Working on the battery fill or HV system;Reconnecting the battery pack to the vehicle;Conducting diagnostics the the HV system and also connections.

3 - Insulated safety and security Footwear Ratings and Safety Guide

Electrically insulating footwear is experiment at the proper leakage current test voltage because that their class rating, (see table below), for 3 minutes during which the leakage current must no exceed the maximum allowed value because that the class rating. Because that initial certification that a product, the shoe/ boot is experiment to the withstand test voltage, yet this is taken into consideration a terrible test.

As insulated safety and security footwear is additionally classed as safety and security footwear they will likewise meet the required standards that EN ISO 20345:2011. This standardswill include such points as on slide resistance, toe protection, resistance to chemistry etc.

Warwick Test gives recommends course 0 rated footwear for PHEV and also EV automobile maintenance and diagnostics.

Periodic Inspection

Periodic Inspection is composed of the user visually assessing the footwear for any kind of deterioration or defects. The is a good idea to record and log this inspections.


Insulated Shoes/ Boots must also be electrically tested every 12 months following their very first use. This deserve to be done by a electrical testing laboratory who will worry a check certificate or it may be beneficial and/or expense effective to replace the footwear every 12 months.

Obsolescence Period

Typically, the last obsolescence date of insulated footwear is 3 years from the day of marking shown on the shoe.

6 - EV Diagnostic Technician Footwear - Summary

Diagnostics and repair that EV and also PHEV vehicles will always be connected with an electric safety risk, together energised circuits pose danger to life from electrical shocks. Your footwear could be the last line of defence in between you and also a fatal electrical shock native the vehicles battery pack. Yet It"s vital to mental insulated safety and security footwear is only component of the PPE perform that must be worn when conducting occupational on battery packs whilst keeping or repairing EV/PHEV vehicles.

Electrically insulated footwear is accessible in a number "Classes" dependant ~ above the level the voltage they space designed to protect against. The proper Class of insulated footwear for functioning on EV/PHEV is class 0.

Buyers advice

- buy Certified 1000V class 0 Insulated Footwear indigenous a reputable brand;

- examine the sole and also shoe before every use;

- course 0 Insulated safety and security Footwear has actually a 12 month working life from date of very first use prior to requiring an electrical test or it is in replaced.
