Interesting arguments, folks. However, there are some differences in our uses of language here; just to start with. There is, in fact, no such thing as a risk assessment and, of course, you can't 'spot' a risk.
We assess hazards and their potential consequences (usually at their reasonably foreseeable worst) and then assess likelihood (in general, the effectiveness of existing controls for preventing it from going wrong). Giving both of these a value of some sort allows us to come up with a risk value (often described as High, Med or Low) If you read many of the postings and indeed 5 Steps, you will see the 'Assess hazards and risks' So hazard x risk = risk? I think not. Risk is simply a numerical tool that, for the sake of priority, allows us to distinguish between the important and the not so important. RISK is not a physical thing it's a concept. The axis in a matrix such as that used in assessment are independent variables.
Sure, in simple terms everything could be assigned a risk value, but fortunately the law allows us to negate the insignificant ie that to which we cannot assign significance.
Now, to the original post - with which I wholeheartedly agree. The difficulty here is that many people set out assessing without a plan. Often performing a risk assessment only to find out that the task has insignificant level of risk. The danger for the 'backside coverers' who WILL assess everything is that if you have assessments for the insignificant, where do you stop? Blinking, swallowing, breathing? The key is to start assessing at the clearly significant end of your task listing (see previous posts - you cannot start without a list of tasks that might need assessing or else you are simply guessing). As you work through the significant TASKS (not risks) there will be a point where you start to approach insignificant findings. Now, as there is no legal definition of risk assessment, your task listing containing a sample of those tasks that you deem insignificant in respect of needing an assessment remain as proof that you at least considered these activities on paper. Your evidence that you have not been negligent in failing to assess everything is proven by the fact that you looked systematically and that you did assess the significant tasks and recorded significant findings. We seem to spend more time arguing over the insignificant than the significant.
If you can prove that you have all of the significant findings recorded, then by exception everything else wasn't worth bothering with. How will you prove that you HAVE all of your significant findings? We really have to get back to the spirit rather than simply the letter of the law. All of these myths surrounding risk assessment are largely of our making - therefore they are also ours to dispel.
I agree that risk assessment findings are not binary; OK to proceed - not ok to proceed. That only gives you two risk regions. Low risk = we do this fairly well and we're not prepared to put much more effort, if any, into it. High risk, this needs to be at the center of our radar, we MAY need to consider not doing it even temporarily, or at least have a very good reason for doing it if we have to. Medium risk, well it could be worse, but it could perhaps be better - this needs to be next on the radar depending on the composition of the maths that got it to medium. Forgive me but where in any of the regs does it say that you cannot perform a task that has been rated as high risk?
