About diving safety

A spokesperson from DIPNDIVE commented on the study, saying:

Diving safety relies on a mix of environmental conditions and regulatory oversight. Factors like visibility and water depth are crucial for divers to navigate safely, but it’s the less obvious elements—such as proximity to medical facilities and the presence of well-enforced local regulations—that can make or break a safe dive.

Even in locations with excellent water clarity, risks like marine life encounters or delayed medical response time can add layers of danger. Strong regulations and preparedness are essential for mitigating these risks and ensuring a secure diving experience.
