CHAPTER 15
Ventilation:
Tactical Priorities
Basic Indicators of Roof Collapse (Fire Fighter II) 1

2. Fire Fighter II Objectives
List the three tactical priorities in structural firefighting operations and how the tactical priorities affect ventilation operations.
Identify the warning signs of roof collapse. 2

3. Venting for Life Safety
Gives occupants a greater chance to survive
Makes searches faster
Limits fire spread to other occupants and fire fighters 3

4. Venting for Containment
Second highest priority is to contain the fire and control the situation.
Prevents fire spread
Makes fire attacks easier 4

5. Venting for Property Conservation
Can significantly limit property damage
Rapid ventilation reduces damage from smoke, heat, and water. 5

6. Basic Indicators of Roof Collapse
Visible sagging
Roof separating from the walls
Structural failure in another portion of building
Sudden increase in fire intensity
High heat indicators on a thermal imaging camera 6

7. Summary
Ventilation is related to life safety, fire containment, and property conservation.
Fire fighters should be aware of the roof condition when performing vertical ventilation tasks. 7
