In case of loss of oxygen for more than 15 minutes, what is the immediate action recommended?

In the event of a loss of oxygen for more than 15 minutes, the immediate action that is recommended is to contact the DMO (Diving Medical Officer). This step is crucial because the DMO is responsible for overseeing the health and safety of divers and can provide expert guidance on how to address the emergency situation. They can assess the severity of the oxygen loss and advise on the best course of action, ensuring that proper protocols are followed to secure the safety of all personnel involved.

The recommendation to contact the DMO emphasizes the importance of communication in emergency scenarios, allowing for a coordinated response based on the latest medical expertise. Rapid reporting can lead to swift intervention and potentially prevent any further complications from the incident. This fosters a culture of safety and reliance on professional support in critical situations, rather than taking uncoordinated or potentially hazardous actions.
