Its amazing eh mate...you should be given a free copy when you get your first license, then a free replacement should you ever need a one. And any amendments should then be sent out to glue in, for all license holders. All this should be subsidised by the government.
Isn't it all about getting the info out there so its all done safe and well.... but its treated like some secret black art by some, with the knowledge to be sold and not shared.
I was at a standards meeting about 10 years ago, I asked why the standards weren't written in laymen's terms and not in a type of legalese that was a bit confusing.....
The guy running it said "we don't won't just anyone off the street to be able to understand it".....Well....um er ....that's where most of us come from....

The powers that be should assist the trades to do their job to the best of their ability, and foot the bill....most of the everyday plumbers I know.... want to do the right thing and do it properly, the ones I have met who don't care and are dangerous are the ones connected who get it all handed to them in their little clubs...it is totally f****ed up.
