And one of my goals as the instructor is to break down those barriers and try to understand, to get both sides to understand, that the engineer and the technician are basically the same thing from different points of view. And, of course, this applies to how those instructors or how those instructions are made and followed. Of course, some simple ones, keep hands away from moving rotating machinery, that's pretty easy one. So, you know, that's one of the things to, you know, if you're like a, you know, a lot of the guys who make decisions or you have sales when they come in, where they look nice in their suit and ties, are the reasons why the technicians will tell them, "Hey, you can't be here. We don't want your, you know, your clothes, your ties or anything else that you're wearing get stuck in this, it's for your own personal safety."
Likewise, the technicians that goes back, you know, no watches, rings, no necklaces, you know, make sure they're wearing eye protection. Make sure they're hard hat fits. that kind of stuff. So do not use the machine if you have not been shown how to properly operate it, safely that is. And that makes perfect sense too. If you don't know how to operate it ask somebody or the very least, read the instructions. So always ensure a guard which is in a place of equipment is not locked out. Well, in general, if the equipment is supposed to be worked on anyway, the rules of thumb say to lockout tag out but as operators, many operators know that they have to guard the equipment if they're going to be walking away from the station prevent operation that shouldn't be there
Also, one of the things I teach in my classes too, are the various types of hand tools. Now, I don't, when I teach this, I tried to be careful because last thing I want to do is insult other people's intelligence as most technicians know the way around a wrench, but at the same time, they're also some specialty tools out there. Some small things like, for example, your electrical, you see your volt and [inaudible 00:42:59] electrical safe tools, should not be stored in a bag like the rest of your wrenches and pliers. They should have their own special case, mainly because those other tools will tear up those electrical safe tools rendering them not safe for electrical use.
Other things would include like how to use a torque wrench, for example, the correct way to do it or how to use like fuse pullers over say channel locks, for example. Some of those things are pretty no-brainers, but we got to bring them up there to remind to remind all us, so even I need a reminding. So yep, you know, that's probably the better way to do it. So know where the emergency stop buttons are located and keep in mind there's a difference between a stop button and an emergency stop. An emergency stop is designed to stop the entire machine all sources of power so when you hit that thing, it's going to do a hard shut down
Now, understanding this from a technician point of view is understanding that when it hard shut down, you're probably going to have problems when you bring it back up. Some safety things to take it or no is anything that stores energy, now is just sitting there with this energy store like capacitors, or if you have any hydraulic system is holding a load in place above your head or something of that effect, because when you turn ... You may have to go into a process to render it into....it's a safe normal startup process. So yes, the emergency stop is supposed to be hit in the event of an emergency, but the same time take into account that when you turn it back on, it probably isn't going to behave like you think it will.
So once report any damage of any equipment like that could cause an accident. Yes, there's an underlying fear that if I accidentally break something, or you happen to find out that it's broke that you're going to get held responsible and I don't know, my personal opinion in that whole thing is that, I would rather have you tell me that you broke it or that it broke the and find it out that way than what...someone else comes by and discovers that what it is either because they got hurt or because they interrupted a process which that equipment was part of.
So that's really what you weighing out this, and this is also a good point to point out a healthy work environment in that to not create environment where those who can report stuff don't do it out of fear, because as far as good maintenance goes, many eyes are better than once....than fewer eyes. So if you have an environment that allows no matter who sees anything, that doesn't quite look right, then at least what you can do is take someone who has the necessary training to go over there and evaluate it, is this a good or a bad thing.
And then, of course, always be patient. Never rush through a job and we could talk about this if you will, but this is one of those type of things, it's like anything else. Slow and steady on a job, especially the more hazardous it is, it's where good maintenance planning comes into play. And sometimes, this is why you would put in more stringent steps into a maintenance program is to prevent the whole rushing of it because it's important to take your time on it in order to alleviate any possible stakes that will cause any major issues.
And I stand by this because that's one of the things like if you ever work in a nuclear industry, that's how it is. They're always about step by step to make sure that you don't skip a step or do a step out of the order, so that way we don't have a cascading problem. So this is one of the reasons why the nuclear industry is still on record the best as far as safety is concerned, the safest industry yet is because this is the way that they approach all of their maintenance.
So also when troubleshooting. So troubleshooting, you must protect against three halves when it comes electricity. We talk about this in this course, it's an abridged version of our already existing electrical safety course. And so we talk about the three hazards of shock, art flash or arc blast. And so, we can't talk about electricity without bringing this up, because these hazards are always a possibility especially when you're dealing with, you know, higher voltage applications, especially when you're dealing with 480-volts and up.
And so these are things that the technicians need to be aware of. And so, like in my class whenever you come to any class I teach with a lot of electricity. One of my primary objectives is to make sure that my students understand the differences between voltage and current and how those can be manifest, how those can manifest into the conditions of shack arc flash. arc blast.
