59. WARNING!
Never direct a fire stream into a vertical
exhaust opening when interior attack
crews are inside the structure because
it will force smoke, heat, and steam
down on them.

86. REVIEW QUESTION
How can a built-in heating
ventilation and air conditioning
(HVAC) system affect tactical ventilation?
13–86
87. • Tactical ventilation of a burning building
allows heat, smoke, and fire gases to
escape to the atmosphere and also
draws fresh air into the building.
• Properly applied tactical ventilation
allows firefighters to see better, locate
victims more easily, and find the seat of
the fire sooner.
Summary
13–87
(Cont.)
88. • Tactical ventilation limits fire spread
and channels heat and smoke away
from trapped victims; but must be
correctly coordinated.
Summary
13–88
(Cont.)
89. • Firefighters must understand fire
behavior, know various ventilation
methods and have knowledge of roof
construction and know how to create
exhaust openings in all types of roofs
that have a variety of openings in order
to perform ventilation correctly.
