Ok, so a fair bit is over the top .... for anyone who is aware and applies safe practices.
I guess there are many sufferers out there due to blatant negligence ... just take 'white finger' among, for example, metal polishers ... It wasn't enough to just have them polishing, using mops and pastes etc, they were given rotary burrs and grinding wheels ... why ? Because companies failed to spend money on developing decent fixtures, machines and methods, such that there was the minimum excess of material on machined parts .... Seen it all happening in a major company, they would not spend until forced to, too late for some damaged people !! H&S actively reduced accidents and disease year on year ... I found it going over the top when dealing with cynics and potential blatant disregarders of rules.
Just imagine what happens and how one feels if a Lawyer should take 'shortcuts' when acting for you on a property buy or sell ... If he messed up you would want his head on a block !! I mean, he only had to follow the rules, laid down to ensure as much as reasonably possible is done to protect .. his customers interests ... ! Never mind his life or health !
