COORDINATED VENTILATION TACTICS

Question 1

When the use of ventilation tactics is coordinated and the ventilation opening is properly
placed, the following can be accomplished

Answer 1

• Increase the survivability of trapped civilians and the safety of firefighters as they
  search for victims and the seat of the fire.
• Control fire development and confine the spread of fire, heat and smoke
  conditions throughout the entire structure.
• Aids in the extinguishment of the fire by removing heat from the structure and
  improving visibility to allow advancement of hose lines.
