(I haven't read the rest of this thread which degenerated into yet another brexit-fest at article _two_ I believe!)
However: ITYF that most of the EU H&S regulations (like much of the rest of EU legislation) was lifted from British standards, regulations and recommendations.
The problem with H&S regulations is the person who is charged with interpreting them.
The problem with interpreting them stems from the likelihood of the firm (or even the delegated Safety Officer) concerned being sued for damages.
The problem with damages cases is the legal profession, who are always on the hunt for "blame claims".
And the problem with the legal profession, in this area, is the judiciary, who consistently make extravagant judgements in favour of chancers, instead of throwing such claims out of court [or at least: awarding token damages], and reprimanding the plaintiff, and the legal firm that brought the case.
The last-mentioned is the main reason why all our insurance goes up so drastically every year: judges, who encourage chancers.
