So all preventive maintenance programs are made of six parts. And so, first and foremost, one of the things that you have to use is constitute what defines a responsible and qualified personnel. Now, the codes various...the various codes out there generally agree that what makes a person qualified is that they have the necessary knowledge, skills, the applicable safety training and, of course, with electrical safety, what was recently added in 2018 70E, was that they know how to do a risk assessment.

And in many cases, keep in mind, that by doing the risk assessment, it doesn't mean that is sit down and have a full blown meeting, you know, do all the math and the predictive algorithms that sometimes can really, the risk assessment just says, him and one other...him or her and one other technician gets together, they say, "Yes, so yes. This right here is this a 480-volt panel, we have to secure from this disconnect over here, we're going to hang a lockout tagout device and I'm going to check it here to make sure this de-energized. Hey, I need to make sure that the blades are on the disconnector..." It's a conversation, that's my point.

That's how you do a risk assessment, with the idea of bringing to the front, everyone who is involved to say, "Hey, these are the hazards that are associated with it. And this is what we're going to do to assess and mitigate the risks that are associated." And so, next is, of course, you can see your survey and analysis electrical equipment. Basically, what that means is like you're the labeling like your arc flash analysis, how often the maintenance is going should be done, taking into account specifically the condition of maintenance. In other words, it provides a baseline when you're conducting your inspections. So what your technicians know what to look for.

And then, of course, program routine inspections, how often to do them? What can we do that we can...What kind of test that we can do this both safe and effective? And the last one is pretty is important, because if you do too many tests over and over and over again, then that can lead to complacency. If you don't do enough tests, of course, then you don't know if something's going to happen. So like I said before, that is a balance of between too much and not enough. At the same time, you don't want to waste the time of your technicians on doing a lot of frivolous work when there's other things that can be...where attention can be directed to. And so, that's kind of the point of a bullet point number three here.

Next, of course, is accurate analysis with inspection and test reports so that whatever those corrective measures are that you that you decide, what those corrective measures can be. Now, how you do this, would be based off experience. And so, this is where your emergency planning comes in the event the case was a catastrophic failure of some kind or you have an unexpected shutdown due to like your power outage or something.

That's kind of what this is referring to here is that you have a place...a program in place for your technicians to address it. Now, yes, not all corrective measures, because that's what's corrective means is that it breaks. And not all the time can you predict a breaking or it could have been something that there's some accident that had happened someplace that no one foresaw.

Clearly, there's not a way....always a way to be able to address that on paper, but at least provide a template and have a plan in place, to address those situations. And, of course, as I kind of alluded to earlier, the performance necessary work, whether it'd be, make sure it's not too broad at the same time not being too specific. And of course, very important is keeping concise and complete records. And the purpose of this is, is so that you can see the trending of your maintenance. And if you keep good records, what that allows you to do is to once again be able to predict or to see what root causes are, because in many cases, whenever you do a corrective maintenance, especially if it's a type of corrective maintenance on something that's new, or that's been rarely if ever done before that it's sometimes very difficult from a troubleshooting point of view to figure out what exactly caused the issue to begin with.

And so, by maintaining records, this allows you to see "Okay, under these conditions, I can see if these regular intervals or whenever something occurs that this is when I get the problem." And so this is where the importance of maintaining good maintenance records comes into play.
