What is required for emergency manning in a chamber?

The correct choice indicates that a chamber supervisor and an inside tender are essential for emergency manning in a hyperbaric chamber. The chamber supervisor is responsible for overseeing the entire operation, ensuring adherence to safety protocols, and managing communication between the inside and outside teams. The inside tender's role is crucial as they are stationed within the chamber to assist the divers, monitor their condition, and respond to any issues that arise during the operation.

Having a qualified inside tender is vital for the safety and well-being of the person or persons in the chamber. They can provide immediate assistance, whether it is administering first aid, managing equipment, or coordinating with the outside tender for a swift response if emergency measures are required. This combination of roles ensures that both operational oversight and on-the-spot assistance are available in a critical situation, enhancing safety outcomes during hyperbaric treatments or rescue operations.

Other options may lack essential roles or elements necessary for comprehensive safety and effectiveness in an emergency scenario.
