Calculate Risk Values for Risk Assessment

Risk Assessment

As we rate risks for the Risk Assessment in the Method Statement Creator. It is important that people be able to understand how the calculate of the values High, Medium & Low are obtained.

How the matrix works

The matrix then works by selecting the appropriate likelihood  from across the top, and then cross referencing against the row containing the consequences . Reading off the risk rating where the lines intersect.

A typical example of Risk Assessments in our normal day to day lives, would be crossing the street. In this instance we are standing at the footpath and see a car coming around 40m away. We know if we step out in front of the car that the chance of getting his is Likely and the result could very well be Critical, using the matrix this shows a Risk Rating of 20 which is High Risk. The control measure is that we will wait for the traffic to clear or walk to the pedestrian crossing where we can cross safety.

We use this ideology in creating Risk Assessments that are included in the Method Statements. Looking at a particular task we are able to identify HAZARDS (How can people get Hurt) then we rate those into High, Medium & Low and put in control measures as shown in the screen shot of a Method Statement below.

LOW RISK:

Generally acceptable.

MEDIUM RISK:

Efforts should be made to mitigate the risk as much as possible, only allowable where the means of controlling the risk is not possible/feasible.

HIGH RISK:

Work activities should not be started until the risk has been mitigated.

MITIGATING THE RISK: 

CONTROL MEASURES/RULES must be put in place to reduce the Likelihood and/or the Consequences of the accident/hazards occurring.
