I'm assuming you mean "Health and Safety" and not one of the many other meanings for that set of letters. On the other side of the pond, where this article originated, H&S isn't really a thing. The closest thing we have over here (and I'm only guessing here) would be OSHA and as a "office worker" I can say they really haven't been a significant part of the my day to day. Might be different in a labor oriented profession though.
