Appendix 1.Risk assessment
& risk reduction opportunity ranking
With all businesses driven to get the most possible value from each and every expenditure, invest-ments in safety should be guided by risk assessment and a structured process to ensure that the funds available are spent on the things that will do the most good to improve safety. The following guide-lines describe a structured process for assessing risk and for ranking risk reduction opportunities in a way to manage risks to a level as low as reasonably practicable (ALARP).
Risk is the product of potential consequence (e.g., fatalities, asset loss, environmental damage) and probability (frequency or likelihood). Risk assessment is the act of judging and classifying the poten-tial consequences and the likelihood of hazardous events. Many companies use similar matrices to the one shown below to assess risk.


The vertical axis displays the potential consequence of an incident and the horizontal axis displays the likelihood of this consequence. The combination of potential consequence and likelihood defines the risk classification.
Potential Consequence is divided into levels running from ‘0’ to ‘5’, indicating increasing severity. A potential consequence should be reasonable and credible; something that could have developed upon the release of the hazard. It is very important to judge the potential consequences in addition to the actual ones. These are defined as the consequences that could have resulted from the released hazard if circumstances had been less favourable.
The overall potential consequence of an incident is established for four different scenarios. These are People, Assets, Environment & Reputation. A combination of these is possible, but the highest potential consequence is normally used for further analysis. For example, if an incident could have caused a single fatality (People 4) and minor damage to an aircraft (Assets 2), the potential Level 4 consequence is then used in the incident classification (e.g., Low Risk, Medium Risk, High Risk).
