Instructor-led discussion of ventilation theory and tactics. Officer selects topic for this session. Topics that fit this sheet include: horizontal ventilation (natural and hydraulic), vertical ventilation (roof cuts — 4x4, 7x9, louver, trench cut), positive pressure ventilation (PPV) — attack vs post-fire, positive pressure attack (PPA), negative pressure ventilation, hydraulic ventilation with fog stream, mechanical vs natural ventilation, coordinated fire attack and ventilation timing, flow path management, UL/NIST modern fire dynamics research, smoke reading, and ventilation of basements / attics / high-rises. Reference: NFPA 1001, NFPA 1410, IFSTA Essentials Ch. on Ventilation, UL FSRI research. Document the specific ventilation method discussed and tactical considerations.

1. 1. Define the ventilation method covered and when it is appropriate.
2. 2. Describe coordination requirements with attack crew.
3. 3. Identify flow path implications and risk to interior crews.
4. 4. Recognize when NOT to ventilate (lack of water, no attack ready).
5. 5. Review smoke reading indicators relevant to the topic.
