So where do you draw the line?
What steps have you taken to address protecting your employees from a meteoroid explosion?
NFPA70E says you need to perform a risk analysis as part of your Safety Program. What values are you putting into your analysis that equates the task of 'replacing a fluorescent lamp' with that of performing a voltage test?
And that is a good question, for which I have no answer. In fact, I don't believe there is an answer! I, as a Project Manager, who doesn't pay the bills, do a job specific hazard analysis and discuss safety requirements for every job with the responsible people on the job. I reinforce this by not looking the other way when I see a violation, but I don't "write people up" usually. I will regret it if one day I say something to an employee and then later they get hurt doing the same thing, but....
For example, if I see someone on the top two steps of a ladder I will tell them to step down right then. I have had workers say something like, "I only have this last screw." I will say, "I don't care, if you can't do it from the correct step than go find the correct ladder. Next time remember that." I have always felt this to be the MOST important thing we can do as supervisors, perhaps besides not standing on the top ourselves!
