Long gone are the days when an employer can assign an employee a task to do without ensuring that the employee actually knows how to do it safely...and can prove it afterwards if/when the SHTF. It's part of due diligence. I don't know how many times I've seen someone answer in the affirmative when asked if they know how to do something but promptly demonstrate they have no clue. I believe it's part of human nature to not want to be seen as being ignorant of something and to be seen as knowledgeable.
