The Mask Removal Panic in Confined Water
You are assisting an Open Water Diver confined-water session in a 25 m pool with a maximum depth of 3 m. There are four students, one instructor, and you. The instructor is at the deep end with Student 1 practising regulator recovery. You have been assigned to supervise Students 2 and 3, who are kneeling in the shallow end practising fin pivots about 5 m from the wall. Student 4 is at the wall practising mask removal. Suddenly Student 4 stands up, pulls the mask off, shouts 'I can't breathe,' and starts climbing the pool ladder. Students 2 and 3 are still kneeling, looking toward the noise. The instructor is 15 m away and has not yet noticed. You are the only person between Student 4 and the ladder. The pool rules require a head count before anyone leaves the water.
1. What are your immediate priorities in the first 30 seconds?

The first priority is to prevent a second casualty and to keep all four students accounted for. Student 4 is at the pool wall and climbing the ladder; the ladder is a controlled exit, so the immediate drowning risk is lower than if Student 4 were mid-pool and panicking. Still, 'I can't breathe' after mask removal is a panic signal and needs a calm, direct response.
- Do not sprint away from Students 2 and 3 and leave them unsupervised. They are kneeling in 3 m of water, but a panicked student can knock others or swim off.
- Signal the instructor with the agreed emergency signal (whistle/visual) and point to Student 4. The instructor is 15 m away and has not noticed.
- Give Students 2 and 3 a simple instruction: 'Stay kneeling, look at me, hold your regulator.' If they are stable, keep them at the wall or have them surface and hold the wall, whichever is safer.
- Approach Student 4 only after Students 2 and 3 are safe and the instructor has been alerted; if Student 4 is already out of the water and sitting on the deck, your role is to calm and monitor, not to restart the skill.
2. How do you handle the panicked student without abandoning your assigned students?
Read the worked answer
Use a 'safe handover' rather than abandoning. If Students 2 and 3 are calm and kneeling at the wall, move them to the wall and tell them to hold it; then go to Student 4. If they are not calm, or if the pool is crowded, bring them with you at the surface-do not leave them alone. At the ladder, get Student 4 sitting down, mask off, regulator out, and reassure: 'You are safe, you are breathing, take a slow breath.' Do not re-attempt mask removal now; panic after a mask removal is a sign the student needs a slower progression, not a correction. Check for water in the mouth, coughing, or dizziness. Once Student 4 is stable, hand them to the instructor and return to Students 2 and 3. If Student 4 had inhaled water or lost consciousness, the priority changes to rescue/oxygen and emergency action plan; the instructor takes over. The divemaster does not teach the skill or certify the student.
3. What do you report to the instructor, and what should you not do?
Read the worked answer
Report: what you saw (Student 4 stood up, removed mask, said 'I can't breathe,' climbed ladder), timings, what you said and did, Student 4's condition, and the status of Students 2 and 3. Also report that the instructor was 15 m away and did not see it-not as blame, but because the instructor needs the full picture for the student's records and for adjusting supervision. Do not: teach the mask-removal skill yourself, tell Student 4 they 'failed,' promise confidentiality beyond the instructor, or skip the head count. Do not leave the pool deck until all students are accounted for. If the incident suggests the instructor's ratio or positioning was inadequate, raise it privately after the session, not in front of students.
