Risk assessment

Risk assessment is a systematic review of what might cause undesirable incidents and what consequences these may have for the working environment. A risk assessment must also identify measures that form a basis for reducing risk.

Risk analysis

The purpose of risk analysis is to find the causes and consequences of undesirable incidents.

A risk analysis is performed by a work group and the analysis itself must contain the following points: 

  • Identification of undesirable incidents: Review of what the hazards are. Experience and history (earlier documents/analyses) can certainly be used here. 

  • Causal analysis: What are the causes of the undesirable incidents? 

  • Consequence analysis: Outlining the various consequences of the incidents. One incident may have several consequences. The consequences may also be dependent on each other. 

  • Presentation of risk pattern: Expression of expected values and their size and probability. This can be demonstrated with a risk matrix, for example. 

  • Assess uncertainty: Consideration should also be given to uncertainties with the anticipated values and probabilities. 

Templates for risk assessment:

By combining probability (1-5) and consequence (A-E) for an unwanted event, we can visualize risk in a risk matrix. 
UiB has predefined criteria for probability and consequence that can be placed in the associated risk matrix.  
The event will be placed in green, yellow or red area of the risk matrix. 

Here is a summary of what the colours indicate: 

  • Red is not acceptable and risk reducing measures must be taken immediately. 

  • Yellow indicates the need for the introduction of risk-reducing measures. 

  • Green indicates acceptable risk. The introduction of measures should be considered if the effects will obviously be good.
