This video explains how the HiLo model works. HiLo prioritizes based on risk. The model has analyzed thousands of maritime industry accidents and then calculates the probabilities of leading events, causing undesired events.
Traditionally, maritime organizations plan safety campaigns by assessing the number of times accidents have happened. They then prioritize from the the highest number of occurrences to the lowest.

On the other hand, HiLo analyzes thousands of maritime industry accidents and then calculates the probabilities of leading events causing undesired events. The frequency of occurrences, multiplied by the probability and the impact of an undesired event gives the level of risk.
HiLo is made up of numerous interlinks between leading events and undesired events. The resulting calculations create a risk ranking, in order for companies to focus on the areas that really makes a difference.
