Which of the following is NOT a component found in the PSOB?

The reason B is the correct choice, as it is not a component found in the PSOB (Post-Service Overview and Briefing) is that the PSOB primarily focuses on operational guidelines, safety protocols, and the technical performance of life support systems used in diving. It includes elements that are crucial for the safe and efficient functioning of diving equipment and the overall diving operation.

Operational parameters are essential as they outline how systems should function under various conditions. Air/gas/oxygen supply systems are fundamental components as they ensure divers have the necessary breathing gases to survive underwater. The diver handling system is also critical, encompassing procedures and equipment designed to ensure divers' safety during deployment and recovery.

In contrast, diver victim case studies, while valuable for educational purposes and understanding incidents for future improvement, do not directly pertain to the operational and technical components that the PSOB addresses. Hence, these case studies would not be included as they are more aligned with training and analysis rather than the core components of a safety and operational briefing focused on diving missions.
