A hazard assessment is a systematic evaluation of the potential dangers associated with an activity, installation or process. This study identifies the risks and associated consequences, as well as the measures to be put in place to reduce the risks.

To carry out a hazard study, it is important to identify possible sources of danger, the events that could occur and the consequences associated with these events. This analysis can be carried out using a variety of techniques, such as scenario analysis, fault trees, flow diagrams and so on.

The results of the hazard study must be used to draw up a risk management plan, which defines the measures to be put in place to reduce the risks identified. It is also important to put in place monitoring and control procedures to ensure that risk management measures are effective.
