And so, the practice for electrical equipment maintenance like I said, course NFPA 70B and the part of this is also maintain the components of your electrical maintenance. Now, one of the most prominent components of this is, of course, your policy regarding worker energized equipment. Now, I do understand that sometimes it may be necessary, but my personal opinion and what I recommend to every single one of my classes is that, never work on energized equipment. And the reason for that is because electricity behaves in mysterious ways as it goes, and as a result, you're increasing the probability for a mishap to happen.
Electricity is something to always respect and take it and take into consideration when dealing with any equipment that works on electricity, which for most of us, it's almost all of our equipment. And so, one of the most important components, I think of an electrical preventative and maintenance program is the policy which many companies already have is to not work on energized equipment. And if you were to take my class, I'd be happy to tell you any situation that you give me, you say, "Well, we have to work on what's energized." Obviously, I'll give you a better, a safer way to do it. And so, and I tried to even go...even though...the even the law states that when it's infeasible or if it will introduce additional hazards, there are ways still to establish an electrical safe work condition with those in mind.
And so, that's pretty much the whole big point I'm making a lot of my classes. All right, so last is trouble...last part of this is troubleshooting. And so I built a lot of the programs associated with the troubleshooting with a lot of examples with the intent of the examples to one, discuss the operation that equipment based on limited knowledge. Because a lot of us as technicians, we have the expectation that if it's broke, go fix it. And whether we know anything about it or not is that generally a good excuse, because sometimes things happen and, you know, that technicians the only guy that's available, but the cool thing about it is though, is like especially for taking my classes, I go into trying to equip those guys with you can fix anything, because a lot of this stuff has a very same principles across the board on each piece of equipment, and the same principles can be applied across the board.
Same principle applies and all this with how to troubleshoot. And so as you can see up here, know your system and equipment. So, from a management point of view. One thing to take into consideration, especially if the technician is inexperienced with that specific equipment is to give them the time to do the necessary research. I mean, speaking for myself, I've been a technician for over 20 years now. And when I've been...and teaching this stuff, if I know nothing about the equipment. Generally, if I think I can fix it in 20 minutes, I won't tell you, "Give me three hours." Because I'll run across something that didn't know before, but the advantage of that though is, is next time I come back to it in the future, I'm going to know a lot more about the equipment, because I took the time on the onset to get to know my equipment.
And of course, knowing the test equipment portion of it is understanding what test equipment you have available to you that will help you, but not just your multimedia, but things like an oscilloscope or, you know, if you have micrometers, excuse me. Whether to use a mega. One of the tools you have available, and the various ways you can use that. So one of the portions of the course that I teach is exactly that. What test equipment like a mega, how the limitations of multimeter, I have the ability. Someone wants to know how an oscilloscope works, I can teach on that. I also talk about micrometers, precision levels, those kind of things.
And then, of course, going into following safe work practices. And really what I go to in this is to squash the idea that just because you're troubleshooting does not mean you have a get out of jail free card in reference to working on energized equipment. You still need to follow safe work practices. Even though troubleshooting is one of those types that says, Yeah, I can work on energized equipment if I'm troubleshooting. No, that's not your ultimate get out of jail free card, the hazard is still there. And so that...and that's what this means by following safe work practices.
