In FADS3, what is the main purpose of the isolation valves on the top ports of each flask?

• A. To release trapped air
• B. To control individual flask operation
• C. To prevent overpressure
• D. To regulate air flow

Answer: (B)

The primary function of the isolation valves on the top ports of each flask in the FADS3 system is to control individual flask operation. These valves allow a diver or operator to isolate one flask from the system while allowing others to remain functional. This feature is critical when maintenance or repair is needed on a specific flask without affecting the overall functionality of the other flasks in the system. By enabling the management of gas flows and functionality on a flask-by-flask basis, the isolation valves enhance operational flexibility and safety. For example, if one flask encounters an issue, the isolation valve can be closed to prevent any potential adverse effects on the diver's supply, ensuring that other flasks continue to function normally. This design is essential for maintaining the integrity of diving operations, particularly in environments where divers depend on reliable gas supply systems. Other choices may refer to aspects of air management or safety, but they do not directly address the specific role of these isolation valves in managing individual flask operation within the system.
