John: Good morning. Welcome to this morning's webinar on Electrical Safety in the Workplace, the 2018 edition of 70E. First things first, I know you all probably have a lot of questions. So if you notice, on the right-hand side of your toolbar there, there's a little drop-down for questions. Simply type your questions into that message bar, and we will answer all questions at the end of the presentation.
One of the most popular questions we get is, "Do I get a copy of the presentation?" and the answer to that is absolutely. At the end of the webinar, you'll get a thank you email from us. Please just respond to that email, requesting a copy of the presentation, and I will get that out to you in the form of a PDF. Also, if you have to miss some of the webinar or if somebody in your organization misses some of the webinar, we will have this up on our YouTube channel, hopefully, by the end of today, certainly, by the beginning of next week. So it will live there for you to view at your leisure, anytime you need to.
With that, though, I'd like to introduce our speaker today. Bob Clukey is a TPC Trainco electrical instructor. He's also an electrician, and he has decades of experience in electrical safety and is one of our top electrical instructors here at TPC Trainco. So, without further ado, I'd like to welcome Bob Clukey.
Bob: Thank you, John, and welcome, everybody, on this call. So today we're going to go through the upcoming changes that the 2018 edition of 70E is going to give us. I want to let you know that this presentation has been based on the 2nd revision and plus the NFPA conference that was held in June. The 70E will be available for us to purchase on September 25th, so just a few more days and we'll be able to actually have the PDF in our hand. First, I'll give you a little bit of idea about TPC Trainco, who we are. So we like to say that we are a full-service training company, and we have a product, TPC Online, where we do live online training in your facility in an online format. We also will do consulting to see if we could help you with really anything in your facility from mapping out your machines with our iSchematic format or having actual live instructors come through TPC Trainco. So we have online courses. We have consulting services. We have opportunity to map out your machines, your hydraulic systems, your electrical systems, pneumatic, and also live instruction. Okay, and John already mentioned about me, but you get to see a picture there, so that is fine. And we'll get right into the meat of the program.
So the first change that comes up is in the scope of NFPA 70E, and this aligns with the National Electrical Code, what they did with the 2017 code that now the removal of conductors equipment is now covered under 70E. So if we are removing equipment, then all of the safe work procedures in 70E should be in place. Notice, if you do see something underlined, then that is the change. So when we look at the 2nd revision on the NFPA website, this is exactly what we would see, this was copied and pasted right from there. So in Definitions, arc flash hazard, they now put in a source of possible injury or damage to health. So want to understand that the arc flash is tremendous amount of heat and gave us this definition to help clarify that.
Electrically safe work condition in Definitions has also been changed just a little bit. And in a minute, we're going to see that there are even more steps now to achieve that electrically safe work condition. In the 2015 version and prior editions, there were six steps, now there are eight steps. But in this Definition, now you can see that they have put in the word, "Verify the absence of voltage," and, "if necessary, temporarily grounded for personnel protection." Of course, usually that happens a lot of times with higher voltages that we have to put those ground straps on, but they wanted to get that in the definition.
So I did mention that there are now eight steps to establish an electrically safe work condition. This is one of the steps that we have always had. We had to identify all possible sources of power coming to the equipment. And this step also was one that we had to properly interrupt the load current and then open up the disconnecting means, and the visual verification was always in there, also. This is brand-new. So now we have to release stored energy, and this could be capacitors, you name it, whatever it might be, but we've got to make sure that all stored energy is now no longer at the machine. And brand-new, step number five, we have to block that stored mechanical energy. So whatever it might be, gravity, whatever it could be, now we've got to, not just have a good understanding of the electrical functioning, but we also have to understand the mechanical ability of that machine. So we have to be able to block all stored energy, and that is going to be very nice for technicians to keep themselves much safer.
