"Perfection it's not magic, but it's the art of doing things over and over and over." Philosopher DJ Kyos.
The work we do for utilities can be very unforgiving. We need to be focused and well prepared to safely preform the jobs that we do. Part of being well prepared is having the training needed to do the work. Just because you might get more money for doing work above your classification, does not necessarily mean the you've been properly trained for the work. If you are not properly trained to do a task, don't do it! It's just that simple.
We should never put ourselves in a position of undue risk. It might be a piece of equipment you have not encountered before. Don't work on or around something that you're not trained on. It could be a wireguard that is told to go patrol a line. If you are not trained to patrol, don't. There could be a downed power line on a barbed wire fence, when that wireguard goes to go over the fence, that's it. It could be new equipment in a substation. Don't guess, get help and get trained. If you're being pressured by a supervisor to do something you're not trained to do, tell the just that. I'm not trained to do that, it wouldn't be safe.
You wouldn't jump in the cockpit of an airplane and take off trying to fly, why would you work on something you don't know about? It's just as dangerous. If you don't know what to do, don't try. You cannot bluff your way through it working with electricity and gas.
Ask your supervisor to get you the training you need. Become familiar with Standard Operating Procedures (SOP's) and the Accident Prevention Manual (APM) as they pertain to what you are doing.
Let's all go home to our families healthy and uninjured.
