When changing a breaker in a homeowners panel are we supposed to call the utility company and disconnect the service, or pull the meter out? I believe you have to work on a live panel to change the breaketr

After 37 yrs. working in an industrial plant as an electrician and for about 20 yrs. of that time as a troubleshooter of elec. problems I have seen the results of Arc Flash on the body of 2 men. I have spent 10 yrs. on a safety team and I came to realize that theres this Macho thing about working live. When I approach certain workers and and try to convince them that what they are doing is not safe and they are putting themselves in harms way, I would get a look like a deer in headlights and some would dismiss me as an old fool. I came to realize that safety is in your own mind. Companies provide all the required traning and equipment for you to work safer but if ignored eventually if you work long enough in this trade you will see the results of unsafe work practices. Working with electricity is like playing Russian Roulette. The less safe you work the more bullets you chamber. Think of your family! You owe it to them. Theres a poem I could have saved a life today, but I chose to look the other way. Don't look the other way, Stop unsafe practices when you see them and you may be ablee to save someone's life today.

Is there a US version of this criminal code?

All people neeeds more information about it and takes responsability to do it. itīs for us and our family.

Just a show of hands now: Does anybody turn off the main when pulling the panel cover?

The functional training to electricians should include safety aspects in all scenarios such as while working on live lines or in their vicinity. These should be explained with case studies followed by a practical on the job demonstration by a trained electrician. Electrical workmen should be made aware of the need to wear personal protective equipment while working and that they should ask for providing all these items and ensure use before commencement of work.
