Freedive safety is a culture: a watching buddy, a conservative turn, no hyperventilation, and a surface protocol that lasts until the diver is clearly themselves again. Shallow-water blackout — loss of consciousness from hypoxia, often near the surface — is the distinctive hazard. (1)
Wow factor is low on purpose. This chapter exists so the freediving topic does not have to carry the whole argument. Risk remains high because the physics does not care about a holiday mood. This is not medical advice, not a rescue certification, and not a live dive plan. AIDA and national bodies publish safety regulations for competitions; clubs copy the useful parts.

It lowers carbon dioxide, which is part of the urge-to-breathe signal, without adding a matching oxygen store. Courses treat it as a blackout setup. A scuba diver on a regulator is not automatically a freedive safety. The roles differ. Train together or do not depth-dive.
AIDA events specify safety freedivers, oxygen and protocols. Recreational bays do not, unless a club brings them. Working breath-hold cultures always had informal pair habits. Formal freedive safety is a sport-era invention: AIDA competition rules, club surface protocols, and a literature of blackout that grew as depth records grew.
