WPD’s Safety Footwear Solution

Electrical Safety Equipment LV MV HV 

Western Power Distribution are the electricity distribution network operator for the Midlands, South West and Wales. They deliver electricity to over 7.8 million customers over a 55,500 square kilometres service area. A network which consists of 220,000 km of overhead lines and underground cables, and 185,000 substations resulting in the employment of over 6,500 staff.

Rock Fall design and develop electrical hazard linesmens boots and shoes to impede the flow of LV MV HV electricity through the shoe and to the ground reducing the likelihood of electrocution, in accordance with ASTM F2413-11.

Below is a case study of how Rock Fall and Western Power Distribution have achieved an electrical safety footwear solution meeting all the necessary standards.

The problem

WPD felt they had a few problems with their electrical safety footwear solution. These included:

  1. Missing specification
  2. High costs
  3. Requirement for bespoke design choices

The story

Western Power Distribution approached Rock Fall to develop a range of styles to protect them from the electrical risks that they face. WPD were fully aware that these styles are designed as secondary protective equipment for use in addition to other electrical hazard protection equipment i.e. insulating gloves. Key features of these electrical safety products are:

  1. Certified to 18kV protection in accordance with ASTM F2413-11
  2. Waterproof tested for 100 hours
  3. New design features including yellow collar and lacing and new outsole mould compatible with climbing irons

Rock Fall supplied wearer trials to several operatives across a variety of business units.

The trialled products were:

Rock Fall RF800 & RF900 certified to ASTM F2413-11 as well as EN ISO 20345:2011

Rock Fall RF800 & RF900 certified to ASTM F2413-11 as well as EN ISO 20345:2011

Rock Fall RF800 PowerMax Linesmen Boots

  • EN ISO 20345:2011 SB P CI E FO WRU WR SRC.
  • ASTM F 2413-11 I/75 C/75 EH PR.
  • AS/NZS 2210.3:2009 SB P CI E FO WRU HRO WR SRC.

Rock Fall RF900 Power Linesmen Boots

  • EN ISO 20345:2011 SB P CI E FO WRU WR SRC.
  • ASTM F 2413-11 I/75 C/75 EH PR.
  • AS/NZS 2210.3:2009 SB P CI E FO WRU HRO WR SRC.

This gave them 2 highly durable products that are designed for both Linesmen and Jointers.

Rock Fall brought together a range of advanced components used in their existing market leading products. Including:

  • FORCE10® Scuff Cap and Brand New Outsole – tested to extraordinary performance levels
  • R-TEN™ Abrasion Resistant Thread – Chemically inert and highly abrasion resistant
  • Ortholite® Climate breathable footbed – reduces foot swelling and provides anti-fatigue and moisture wicking properties
  • IMPACT SHIELD™ Internal Digging Plate – reduces impact into the under-foot and increases stability

Finally, Rock Fall have added a yellow collar, meaning that wearers can be identified to be wearing the correct EH Footwear from a distance by Health and Safety and Site Managers.

Linesmens Boots

Linesmens Boots


Following a diligent trial and development process the RF800 PowerMax and RF900 Power were specified on the Western Power Distribution safety footwear tender that took place during Q4 of 2017.

The linesmen boots are on the ground and wearer feedback is continually being monitored.

Matthew Noon, Director at Rock Fall and Lucine Evans, Safety Advisor at Western Power Distribution worked together on the project.

Matthew said “We are thrilled to have had the opportunity to work with Western Power Distribution on such an important project for both them, and the industry. Rock Fall has positioned itself as the go to manufacturer for end-users when they need something brand new. Working with WPD has been a pleasure from start to finish and we are proud of the results.”

Lucine said “As a business we had been waiting for an electrical hazard boot which was CE marked to come on to the market, so we were more than happy to work with Rock Fall on the development of these work boots. Throughout the process Rock Fall have listened to our feedback and the result is two styles of work boot that are fit for purpose, comfortable, robust and meet WPD’s minimum standards for footwear.”

Rock Fall are eager for ongoing user feedback so their electrical hazard footwear and dielectric boots can be reviewed to ensure the continual performance and value for money is achieved.
