I agree that the phrase “as far as possible” is broad and difficult to quantify. Because there is no way of knowing how many risks that may exist but haven’t been identified. Because of this it isn’t possible to reduce risky 100% or by any percentage. Without being able to quantify the reduction in risk I think that the phrase as far as possible is actually a good guideline to follow for risk analysis. This phrase means that a company should ethically devote resources to exhaustively identify any and every risk possible and properly designate and address each risk. In this situation I believe the highest majority of risks can be reduced.
