We put the questions to James Cornet, CEO and Founder of TradeFox, to learn more about the introduction of a brand new simulator that aims to improve understanding and application of safe isolation best practice.
Q. What’s your background and where did the idea for your new safe isolation training simulator come from?
Because my family ran a construction/development business, most of my earliest memories involve being on building sites, so I grew up around it all.
I started labouring at the age of 18 and was slowly introduced to the different trades, working my way up to a construction management role, but I always felt the need to keep training in hands-on disciplines. I was, and still am, obsessed with studying as many trades as possible.
Later, I started studying languages intensively and would frequently use Duolingo as a study aid. I was studying the electrical diplomas at the time and saw the similarity between the trades and languages; they have their own vocabulary and grammar, and I wished there was an education App where it would be possible to learn all the trades.
One of the big turning points in my life was the Grenfell Tower fire. Improving electrical safety has been a goal of mine ever since then. That tragic incident made me realise the deep structural problems within the construction industry, and immense impact it can have on the lives of others.
Another big wake-up call was when the Site Manager who gave me my first job nearly died from an electric shock, due to not practicing safe isolation; there was a secondary supply, and it wasn’t tested for. Similarly, another member of his team nearly died after failing to lock off the supply and the circuit was turned back on while he was working on it.
I’ve made these free simulations for my friends and colleagues who nearly died, for all those who work with electrical systems, who are suffering from electric shock or have been killed by electrocution. Hopefully these simulations can protect those without protection and act as a guide for those without the requisite training.
Q. How does the simulator work and what is it designed to do?
The simulations are designed to simplify complex construction techniques and make them accessible to all. Our platform is principally for IOS and Android, so there are practical limitations that we have had to work with in mimicking a realistic training environment.
The user flow is as follows:
The user has several objectives to be completed on a virtual checklist. To complete this objective, they must select the correct tools, use them in the right places and use them in the right way. On mobile, this means the user will be swiping, pinching and tapping on their screen to proceed. A voiceover will guide the user, and there will be UI UX aids and highlights to prompt the user should they get stuck.
We’ve also built in an undo/redo button so that the user can go back three steps in case a particular technique was missed. The simulations are designed to establish muscle memory for complex construction training techniques so that they can be performed without conscious effort.
Q. Why is it important for the electrical industry to have digital/virtual/simulator-based training concepts, particularly when it comes to a practice like safe isolation?
There is an inherent danger in studying electrical installations, and it’s possible for a student to electrocute themselves while studying in a centre. It is for this reason that there’s a limit on the number of times students can practice safe isolation.
This isn’t the fault of the course or training provider, but a natural limitation of teachers having to watch students conduct safe isolation one-by-one for health and safety reasons.
Simulation training gives the opportunity for students to practice these dangerous techniques virtually, in a safe environment, an unlimited number of times. This type of training allows the potential to explore the ‘what ifs?’ What if the GS 38 Compliant Voltage Indicator fails halfway during the testing for dangerous voltage? What if there is a secondary supply?
The aviation industry has led the way on simulation training. It’s dangerous for pilots to practice emergency procedures, and the safest way to first be introduced to an engine failure or an emergency landing is in a simulator.
Similarly, safe isolation is the most fundamental concept that all electricians must know, yet many apprentices aren’t trusted to work with a consumer unit or distribution board when they start their apprenticeships. The safe isolation simulations are a way of building confidence, and ultimately competence.
Having one standard that everyone can agree on and use is equally important, as different standards can lead to accidents. The work of Team Safe Isolate has led to an agreed standard, the 12 easy steps for safe isolation, and this has meant it’s now possible to create a simulated version of this standard.
Q. Are there different versions of the simulator available to suit experience levels?
We have three different modes to cater to the different learners at the varying stages of their journey.
1. Video
This introduces the techniques to people who might be completely unfamiliar with the subject.
2. With instruction simulation
This version is for apprentices, familiar with the subject but needing to practice. There will be UI/UX aids, and a voiceover.
3. Without instruction simulation
Better suited for the apprentice and experienced worker, this is meant to replicate the transition to ‘no hand holding’ on-site. It will not have UI/UX aids or voiceover.
Q. You’ve been able to seek advice from some experienced professionals working in the industry and in the Team Safe Isolate group. Has this helped with the development of the simulator and what changes have you incorporated, based on feedback?
In terms of technical advice and changes, there’s been lots. The amendments have actually been driving my Project Manager a little mad, so here’s a big shout out to him and my team for putting up with me. In the first build, we locked off at the main switch. This is the way I was taught during my training; however, it is live working instead of true safe isolation.
It was recommended by members of the group to use an external isolation switch, which we subsequently added to the build. I since became aware that teaching to lock off at the main switch is common practice among many colleges in the UK as it is part of the 2391-52 and, I believe, the AM2.
I’m mindful that not every electrical installation will have one of these isolation switches, however live working follows a distinctly different procedure under the Electricity at Work Regulations 1989.
Other big changes were integrating the 12-step method into the build, recently agreed upon by the likes of NAPIT and NICEIC. Their work was the catalyst to making these safety simulations happen, as they’d already laid down a lot of the theoretical groundwork. This meant moving a lot of the steps to different parts of the build.
We moved the user proving GS 38 Compliant Voltage Indicator is still working (Step 4) to before the circuit is locked off (Step 8 and 9). We also moved the placing of the Warning Sign on to the distribution board to immediately after fitting the appropriate lock off device and locks (Step 9), where it was previously after the rechecking the GS38 Compliant Voltage Indicator is still working (Step 11).
Smaller changes involved when to use a Hasp Lock/Multilock. I assumed the Hasp Lock should be used as a default in all circumstances, however there is a risk that in using some clamps, a padlock and hasp lock all at the same time, the combined weight will rip the metal pins on the clamp locking down the circuit breaker. This is an example of the level of detail that we’ve been considering.
For the first padlock we used, I visited a wholesaler and purchased a metal shackle padlock as part of a safe isolation kit. I didn’t consider that there were safer options. We’re now using a model with 6 mm insulated nylon shackle as this is better practice.
I’d like to personally thank every member of Team Safe Isolate for their continued support. It’s an honour to be part of this amazing group.
Q. What are your plans for the future?
Are we likely to see new training modules and concepts arriving? Simulations are an adaptive technology, and we can easily change these specifications as new regulations and best practice emerges.
This and next year, we’re focusing on a free safe isolation series of about 10 simulations to tackle more complex isolations, mainly for single circuit. (e.g. lighting circuits, power circuits, boiler etc).
We’re already working on a more extensive electrical course that will include installation and testing and inspection.
Our long-term goal is to expand into the other trades, and this is something I’m really excited about, though due to the dangerous nature of the training, quality is not something I’m prepared to sacrifice for the sake of speed, and safety must always come first.
Q. How can individuals or companies go about trialling or downloading the simulator?
Are there specific PC, phone or hardware requirements? We have a PC version available along with a mobile version which is available on the App and Android store under ‘Tradefox – Construction Training’.
