For example, if a fill level sensor fails, a tank can overflow, causing a safety hazard. The safety analysis team studies assets to determine loss of containment scenarios, identifies risk levels, and selects the safety provisions that protect against or mitigate loss of containment. Optionally, the team can develop action plans and implement reliability programs to prevent asset failures. The topics in this section explain how to define unwanted situations, create failure modes, perform risk analysis, and develop action plans.
