Re: LOCK out TAG out
Tom Baker gave you the best advice, you need to go to NFPA 70E, this is the "Electrical Safety Requirements for Employee Workplaces".
I worked for the Dupont company and I am now retired. You mentioned that your instructor stated, that if someone removes a lock that is not theirs, they will be fired. NFPA 70E does not state that.
The company that you work for will have their own rules and regulations persuant to the NFPA 70E.
I can assure you that someone that removes another persons lock would certainly receive some sort of harsh discipline. I will give you a good example of how we were to handle a situation of removing someones safety lock on a piece of equipment, at my company.
I have been called at home and informed that one of my men had left their lock on a piece of equipment that they needed to energize.
My first step was to call the employee involved, but if I could not reach him, I would have to go into the plant and make sure that all is safe and clear before I would remove his lock. After doing this, then I would cut his lock off.
I can assure you, that at any good reputable company, that this would be the same standard.
But, again I have heard of cases where locks have been removed without doing any research work, but not at any good reputable company.
