Re: been on many courses where the trainer has no answers
The best (ie worst) one I ever had was the mandatory safety training when going on-site at a certain customer.
Course given by a young lad who had no clue, including a slide on LOTO (lock-out, tag-out). All fine, except the breaker was locked out in the ON position, not the OFF one.
So being the engineering sort (as well as a trainer myself within our company, both for over 25 years) I told him there was something wrong with his slide and asked him if he could spot it.
I left him staring at it and looking confused for a few minutes before pointing out the issue, with the suggest that he go find whoever actually wrote his course and do something highly unsafe to them.
Biggest problem of all though was I went back to the same site a couple of years later and had to redo the course (it was an annual one).
Different trainer (although equally clueless) but guess what, exactly the same (uncorrected) slide.
Deja-vu kicked in, followed later in the afternoon by a quiet word with our company safety officer that if the customer course wasn't corrected, we should threaten stop work and decline to go on-site for safety reasons until it was corrected (ironically the customer in question makes big lip-service about safety).
