Who has the authority to approve exceptional exposure in diving?

The authority to approve exceptional exposure in diving typically lies with the Chief Navigation Officer (CNO). This role is crucial for ensuring authorized operations within the diving context, particularly when deviations from established guidelines or protocols are necessary due to unique circumstances. The CNO is responsible for evaluating the potential risks and benefits associated with such decisions, ensuring that safety is prioritized while still enabling necessary operations.

By involving a senior-level authority like the CNO, the organization can ensure that any exceptional exposure is approached systematically, taking into account the health, safety, and operational effectiveness of the dive team. This level of oversight is essential in balancing operational needs against the potential for risk, thereby maintaining high safety standards during diving operations. The CNO's decision would typically be informed by regulatory requirements and the specific circumstances surrounding the exceptional exposure, underscoring the importance of leadership in diving safety management.

In contrast, roles such as the Local Dive Supervisor or Dive Safety Officer may play significant roles in day-to-day diving operations and safety management, but they do not usually have the overarching authority to approve decisions that deviate from established protocol as that often requires a higher level of responsibility and oversight.
