Gentelmen, I will be teaching a class on general electrical saftey to a group that knows enough to be dangerous if you know what I mean. They are not electricians but they know the basics I would like to touch on lockout tag out go more in depth about arc flash and some grounding for sure. I am also going to stick some branch circuit and overload sizing for motors since these guys are plant mechanics and mostly hack there way around this stuff I was hoping for some feed back on what you guys think or even a syllubus that I may chop up to make fit my schedule, About two hours. I am playing a very fine line I dont want to tell them too much or too little so I am torn anyhoo let me know what you think
 
I looked around a few years ago for information on electrical safety to instruct plumbers, I found a publication by the CDC and built my class around it. It was a four hour class, and was OK. I basically said its up to the employer to determine if you are qualified and provide the appropriate safety training.
 
This is a good basic Electrical Safety video

I show "I felt comfortable" video. A man looses his arm in an electrical accident and describes the accident and life after.

Not much to learn about that video, litle technical info and most students will not be working on power lines so they think it dosent apply to them, there a hundreds of better videos for you to use that dont discuss the perils of making a PB&J sandwich.
 
the trouble with electricity

the trouble with electricity

is that you can't see it, just like some metals that burn with an invisible flame.
Almost anyone can see the danger from moving machinery.

Without understanding of what the instructees role will be in relationship to electrical equipment will be after the course, it is difficult to give advice.

In genereal introducing the concept of electrical energy, its generation, distribution is a good starter with relevant examples. Next step would be the behavior of electricity under normal conditions and under abnormal conditions. Lastly introducting the concept of insulation, overload and short circuit and the various ways those are addressed by equipment engineering, design and construction.

I think i would mostly avoid the LOTO issue. You can't possibly deal with it in any reasonable way in 2 hours, so maybe the answer is to make a point that before working on the equipment it needs to be probably locked out and leave what that means to another class.

It might be appropriate to point out just how dangerous electricity can be if it is not respected. A short video or some photos might be in order, but excessive gruesomeness could be counterproductive. I suspect they all know there is some risk associated with electricity so a gentle reminder might be the best approach.

Beyond that, I think you should tailor the chat to what they do. I don't know what that is, but I suspect it is mostly some light debugging and replacement. Give them some pointers on those aspects, and that ought to fill in the 2 hours nicely.
 
It has been a while they liked the first class so much i am now on my third mostly saftey. I did however stay away from scare tactics you know the scary arc flash videos with the manikin spontaniously combusting. That is until I got a new group that is not anywhere close to being authorized to open MCC cabnets much less to replace a blown fuse!!!!!!! So in this instence the video was apripo needless to say they will not be opening anything again I got a lot of my literiture from my nccer books from when I taught first year and no that was not even close to being enough time

THANK YOU GUYS YOU ROCK
