I think everyone has kind of slipped off the valid points the Mr Moyle has pointed out. It isn't the fact that a risk assessment is immediately required, just that one needs to be done. Risk assessments form part of the ACU applications for course licenses. So one needs to be done every time there is a change to the course. So why has this not happened since 2004 is the real point.

As balin points out, risk assessments are a part of every day living. Pulling out of a junction, crossing the road, a quick risk assessment is done by everyone before we do this. It is also just as important, getting hit by a big red bus because you took a risk is one of the results of a failed risk assessment in everyday life.

As for the rain soaked TT's never happening again, well I seem to remember loads of people slating Neil Hanson for his decisions. Yes I know maybe they should be made quicker, but as everyone knows the weather over here can change so fast you might as well have a quick skeet to se if the cows are standing up or sitting down to get a real idea of what is going to happen. He was obviously making his own valid risk assessments.
