As you know i have spend most of my working life on big building sites all over but most in London,and I can tell you that awareness, safety,and health is the main thing I even think some times over the top but that is just me, but inspections are done now evey few days and it is not just about Asbestos even with dust you must use the right mask gloves Glassis hearing etc hard hats boots etc and if you are seen not to use all this you will be send off site for good, some times on the very small sites they do bend the rules but even then still alot better than years ago,when you get on a building site foe the first time now you must have a meeting where you will be told all about safety and what you can do and not do on that site then you sign the paper that you have been told this.
