What Does Preliminary Risk Analysis (PRA) Mean?
A preliminary risk analysis is an assessment of the level of the qualitative and quantitative risk involved in a clearly defined situation that involves a potential hazard. The risk analysis is carried out prior to the activity in order to specify all potential problem areas and put in place a plan to meet any challenges that may arise.
Safeopedia Explains Preliminary Risk Analysis (PRA)
A preliminary risk analysis will involve an analysis of all of the technical, operational, administrative, physical and personnel variables that effect the situation. These are then paired with specific threats to create what are known as vulnerability-threat pairs. These vulnerability-threat paris are then analyzed in order to determine which existing systems counter measures reduce the threat of the potential hazard.
