- Mishaps [ Time Frame: One day ]Mishaps were reported by scuba divers themselves, at the end of their diving day (the day they were enrolled). Mishaps are precursors of injuries. Injuries are less common outcomes (in fact, nobody got injured), hence we used mishaps - which allowed us to test the efficacy of pre-dive checklists, and do so with limited resources.
- Major mishaps [ Time Frame: One day ]Major mishaps are a type of mishaps
- Minor Mishaps [ Time Frame: One day ]Minor mishaps are a type of mishaps
