What you will learn
- •Unclear supervision means do not begin.
- •Pain, confusion or unusual recovery means stop.
- •Changing conditions require a new briefing.
Do not begin while supervision is ambiguous
Name who supervises the exact task, where that person will be and what the stop signal means. If the answer relies on someone who is not aware of the attempt, the task is not ready to start.
Modify when the task exceeds current control
Shorten distance, reduce resistance, return to shallower water or remove equipment when technique deteriorates without a health warning. The modified task must still have a clear recovery and supervision plan.
Stop for pain or unusual neurological signs
Pain, confusion, faintness, unusual breathlessness, hearing change, vertigo, loss of coordination or abnormal recovery are not cues to try once more. End the exposure and seek appropriate assistance.
Brief again after any meaningful change
A new venue, depth, equipment item, partner role or learner condition changes the risk picture. Repeat the relevant briefing rather than assuming the previous plan still applies.
- State the new condition aloud.
- Confirm the supervisor and exit.
- Only resume when the plan is explicit.
