2. Break down the risk analysis into several stages

It's not possible to carry out a risk analysis using a single method. A risk analysis must be carried out in three stages:

• a hazard identification phase ;

• a preliminary risk analysis sentence ;

• a detailed risk analysis phase.

Each stage in the risk analysis process will be matched by one or more analysis methods to suit your needs.

This figure schematically summarizes the three steps to be implemented, and the minimum data required for each step.
