Initially when you do your assessment you are told to take current controls into consideration as well as the hazards you identify...this gives you initial risk.
Upon eliminating/reducing hazards (using the prescribed heirachy) or creating/modifying controls, or a little of both you wind up with the residual risk....this is the risk you will operate under
In all cases levels of tolerability/acceptability must be established
Hopefully you move from higher to lower risk with either controls or hazard elimination/reduction
Thank you Sir. This means, during the implementation & operational phase, one has to concentrate much on the 'Residual Risk' and should apply whatever controls needed to bring the Risk under Acceptable level (to be decided by oneself).
This makes things a bit clear and as such, wouldn't it be better to first calculate the total risk that a particular hazard poses assuming total absence
Let's put 2 more columns in our table one referring to ' Existing Controls' and another for the remaining or Residual Risk which we still need to control if it is Significant.
Now if we put some additional controls, let its credentials be subtracted from the Residual Risk so as to make all known that this hazard now poses no any risk.
Some more thoughts please...
