Mate of mine was a private building inspector and had been in the trade for 40+ years. He went on a site and the site manager insisted on giving him a full 40 minute induction. As he walked out of the site office he noticed a JCB digger being used as a crane. He went back in and reported a H&S breech to the site manager as well as people working under the JCB load without hard hats. Later he noticed scaffolding being overloaded with heavy blocks, when he got back to the office he reported this as well knowing that each breech was at least 20 minutes work for the site manager.
The next site the site manager said to him "you look as if you have been around a bit, do you want the full induction or just the site specific issues?" My mate took the site specific issues and was out in 10 minutes knowing exactly what the main risks on the site were and the site manager could get on with his job.
The obsession with H&S is way over the top and in my view makes things more dangerous because it gets treated as a joke. Another mate had to put on a fall harness with something like a 15 ft drop, he was working 12ft off the floor, the H&S manager thought this was OK as he was seen to wearing the correct gear even though it was worthless and getting in his way.
I am glad I started working for myself before all the jobsworth H&S inspectors started.
