Which incidents must be reported?

• A. All recompression treatments
• B. Any incidence of Type I or II DCS
• C. All cases of pulmonary over-inflation syndromes
• D. All of the above

Answer: (D)

Reporting dive incidents is essential for safety, medical follow-up, and proper record-keeping. Recompression treatments indicate a significant dive-related illness and require documentation so medical teams can review the case and ensure appropriate care. Decompression sickness, whether Type I or Type II, is a reportable medical event because it signals a risk to the diver’s health that needs medical oversight and data to prevent recurrence. Pulmonary over-inflation syndromes carry the serious danger of air embolism and must be documented for safety regulation and treatment follow-up. Since all of these situations are safety-critical events, they all should be reported.
