Supplementary file 1_An evidence-informed occupational health curriculum for pre-deployment preparation of aquanauts in underwater habitats: a scenario-based framework development study.docx

No Delphi round or validation study was undertaken. Internal project documents only defined the scenario.</p>Results<p>The occupational health curriculum specification contains four domains, ten modules, and 28 observable learning outcomes. Emergency preparedness, physical self-maintenance, psychological and team functioning, and underwater operational safety are separated by immediate performance purpose.

Together, the domains connect worker protection across routine prevention, acute response, psychosocial risk management, and task-specific safety. Three modules carry the psychological and team content. Sleep and circadian management, emotional self-regulation, and crew communication with conflict management are each specified on their own.</p>Conclusion<p>This article offers a preliminary occupational health curriculum for pre-deployment preparation that underwater habitat programs can adapt.

It is evidence-informed and unvalidated. The framework addresses worker protection within a bounded underwater workplace while preserving the authority of diving, clinical, and mission-governance systems. Independent stakeholder review, instructor usability testing, pilot training, and analog-mission observation remain necessary before the framework informs any operational readiness decision.</p>
