The rules and enforcement by the HSE in some areas has gotten ridiculous. Look around many public buildings here (by which I mean places which are accessible to the general public, e.g. shops, offices, factories), and you'll see the marks where perfectly good FIRE EXIT signs have been replaced in the last few years with the new white & green "running man" pictorial signs.

It's now illegal not to have the new signs, and it seems that the HSE considers anyone who hasn't changed over to the new signs to be some sort of major felon!
