TS EN ISO 24808/A11

TS EN ISO 24808/A11 is an amending document for a standard concerned with training for instructors in recreational diving services. From the title, the technical focus is the preparation of instructors who teach rebreather diving, meaning the education, competence and instructional framework needed for working with breathing apparatus that recycles part of the breathing gas.

What rebreather instructor training means in practice

Rebreathers are diving breathing systems that recirculate part of the exhaled gas after removing carbon dioxide and replenishing oxygen as needed. Compared with open-circuit scuba, they involve different operational concepts, more demanding equipment awareness and a distinct approach to gas management, monitoring and emergency response. In general technical terms, instructor training in this field must therefore cover not only diving technique, but also how the system works, how hazards are taught, and how trainee progression is supervised in a controlled way.

Because this listing is an amendment, it should be read as part of the parent standard’s documentary framework rather than as a standalone full rulebook. In the broader recreational diving context, such standards support consistent instructor preparation, clearer role definition, and a common vocabulary for teaching complex breathing equipment. The value of the subject lies in matching specialised equipment knowledge with structured instruction, since rebreather training is inherently more technical than conventional recreational diving instruction.

• Understanding the operating principles of rebreather systems
• Distinguishing instructor responsibilities from diver participation
• Translating technical equipment knowledge into safe teaching practice
• Addressing training needs specific to closed-circuit and semi-closed-circuit systems
