Saving Lives | Arc Flash Clothing & Protection
uploaded by Chris Dodds | Sales Marketing Manager at Thorne & Derrick
“If I wasn’t wearing my PPE, it probably would have been a different story.”
This Case Study focuses on the importance of wearing PPE clothing to protect against Arc Flash in the construction and utilities industries when working around buried services – it could save your life, like it did Eddie’s.
A few years ago, an operative was using a jackhammer when he struck a low voltage electrical cable, which led to an Arc Flash incident.
Fortunately, Eddie was wearing suitable arc flash clothing and PPE which ended up saving his life and protecting him from further and more significant injuries.
We were fortunate enough to meet with Eddie Smith, a Team Leader for construction firm, Clancy Docwra, and his colleagues to speak to them about the day, the incident itself and the importance of keeping people safe while at work.
Utilities | Avoiding Danger from Underground Services
Guidance is provided by the HSE HSG47 Document to utilities workers involved in commissioning, planning, managing and carrying out work on or near underground services – this includes all underground pipes, cables and equipment associated with electricity, gas, water (including piped sewage) and telecommunications.
The video that ProGARM created in partnership with Clancy Docwra is to be used as part of internal training for their operatives and to better educate those working around live electricity, of the realities of the risks involved.
We thought it was too important not to show you, so please watch Eddie’s story below and feel free to share.
Jim Eldred – Operation Manager at Clancy Docwra “I received a phone call mid to late morning from Eddie’s teammate. He informed me that Eddie had had an accident and that he had suffered injuries. I was informed that it was electric and that an ambulance was on route.
For me I was scared, I was pretty worried.”
Eddie’s Jackhammer had hit a live electrical cable.
Stephen Bainbridge – Field Performance Manager at Clancy Docwra “The first thing that runs through your mind is, is Eddie okay? And then you start thinking about his children – because he had a young family and a wife. having children myself, that was my concern for Eddie, is he going to come back from this, is he going to work again? As a team we took it quite badly..”
Eddie Smith “When the Arc Flash hit me – it went so fast. And then everything that happened after seemed to go in slow motion. There were these thoughts running through my head; the first one being obviously my little boy, but also my family and my job, and worry about the physical injuries.
“I had burns all the way up my hands, down my neck, inside my nose, mouth and around my face. But because I wear this PPE it didn’t touch my chest, legs or arms.”
“It’s one of those things you think is never going to happen to me, I know what I’m doing I’ve been doing it years – when it does its a massive shock to you and your family.”
Stephen Bainbridge – Field Performance Manager at Clancy Docwra “We need to get across that it’s not about money, it’s not about how many jobs you get done in a day – it’s about doing that job safely. Mostly. You have to wear this PPE. If you don’t wear it you could be dead with just one cable strike.
Eddie Smith “If I wasn’t wearing my PPE, it probably would have been a different story.”
On seeing the photos, Mark Lant, a Technical Expert at ProGARM said: “Obviously, we’d prefer it if Arc Flash incidents never occurred. However, the fact is they do, and we’re pleased to see our polo shirt performing as effectively in the field as it did in the lab. We wish the operative a speedy recovery from his other injuries.”
The PPE that saved Eddie’s life.
“It’s only when you see ProGARM’s Arc Flash garments in action like this that you realise how vital they are to saving lives in the field. We can perform every test available on our range of protective clothing, but to see real garments in real situations saving real lives is the ultimate proof of our success. When an Arc Flash incident occurs, we know that our protective garments are up to the job.”
Thankfully, Eddie made a full recovery in the end and is now back at work. Make sure that your team can do the same.
Remember, PPE is the last line of defence. Make sure you have safe working procedures in place before undertaking any work near live electricity.
Stay safe and don’t compromise.

STRUTSLAYR | Stocked by Thorne & Derrick
The NEW RIDGID STRUTSLAYR™ strut channel cutter is the latest accessory that makes the world’s most popular press tool even more valuable.
Strut channels are used in a wide variety of applications such as Plumbing, HVAC, Fire Protection, Electrical and Solar for structural support of pipes, ventilation/air-conditioning/sprinkler systems as well as cable trays and solar panels. Before they are installed, each strut channel needs to be cut and deburred; this activity can be a very time-consuming task when it is done with traditional cutting tools like an angle grinder, cold cutting and recip saw.
STRUTSLAYR Strut Shear Head attaches to, and is compatible with, RIDGID 32kN press tools – delivering excellent shop quality with a burr-free cut in less than 5 seconds.
The StrutSlayr offers a shearing operation, where the material gets displaced rather than directly cut. This means that there are no grinding or sawing sparks with this Strut Cutter – just a clear consistent SHEAR cut with a pull of a trigger.
The RIDGID® STRUTSLAYR™ delivers shop quality, burr-free strut channel cuts on the jobsite in 5 seconds or less. Compatible with RIDGID 32kN press tools, the STRUTSLAYR strut cutter offers a clean, consistent cut with a simple pull of a trigger.
*NOTE: Press tools are not included. Not compatible with RIDGID 320-E or CT-400.
 Choose from the RIDGID STRUTSLAYR™ kit 64053 or 64058 depending on die shear size. Available from stock for fast delivery. |
 Request a UK demo of the RIDGID STRUTSLAYR today. |
Portability – The StrutSlayr Head weighs only 5.4 kg and is supplied in a sturdy and compact blow-molded case for easy and safe transportation to any jobsite. Cut everywhere, anywhere!
Long-lasting– Approximately 140 cuts can be expected from a single full battery charge with StrutSlayr Head mounted.
Flexibility – StrutSlayr is highly versatile. It can be easily used on a workbench, on a RIDGID TRISTAND, on the ground or even on a platform.
Accuracy – A built-in measuring guide is displayed on the RIDGID StrutSlayr to accurately measure the size of the strut that needs to be cut. The integrated Strut Support prohibits deformation of the Strut channel and provides a straight cut every time. The strut channel cutter offers reduced risk of sparking when compared to grinders and chop saws and still manages to produce a clean, consistent cut.
Size & wall-thickness – StrutSlayr strut cutter features field-replaceable dies and it is supplied with either a 41×41 or 21×41 shearing die, covering the most important two strut channels sizes. StrutSlayr can be used for cutting Strut Channels with wall-thickness up to 2.5 mm. A minimum amount of 2000 cuts can be expected from each new die set. Efficiency never seen before!
Press Tool Compatibility – RIDGID® Standard Series 32kN Press Tools (such as the RIDGID RP 350-B Tool Kit)
*Not for use with RIDGID 320-E and CT-400 Press Tools

Are you suffering performance issues with your HV Cable Systems?
Our clients have been asking us to provide information on 66/69kV class cable systems.
So here is a view from our database of over 200,000 factory comparable (50/60Hz PD with 5pC sensitivity) tests on recently installed 66/69kV cable systems. The data is not pretty.
We have a ways to go to improve performance on these cable systems.
On the basis of a few projects including over 350 cable systems, 52% (from a 3 phase performance stand point) have at least one substandard component.
Terminations are the worst offenders at 15.5% substandard whereas Joints fair a little better at 3.8% substandard.
We have performed dissections on several occasions. The issues? Installation error.
