Well there is a slim to none chance of people doing arc-flash studies on service equipment. Pretty much every winning bid on contracts are lowest price. Regardless of quality-craftsmenship or expertise.

The mechanical room I'm talking about had at least 4 code violations and hack work.

One more question to everyone. Has anyone ever seen a contractor or employee delt with accordingly? People get away with so much it's hard to believe it happens.

It is extremely graphic, but it makes a very good point.....don't get too comfortable....that is when we make mistakes!

SHUT IT OFF OR WEAR YOUR PPE!

Very good video. ITs 10 minutes of the 23 minute video but it makes a point.
