1. Tactic of creating a draft with an opening above or opposite the entry point so that heat and smoke will be released.*

2. In the furnace tests, which type of window failed first?*

3. According to 2005 statistics, ____ % of floor assemblies were constructed of Wood I-Joist type.*

4. VES should be thought of as Vent, Enter, _______ and Search, to not create a new flow path, causing unintended interior conditions that firefighters may not be expecting.*

5. Higher smoke release rates and heat release rates have ___________ the desired smoke lifting that is traditionally the intent of ventilation.*

6. ___________ is believed to be one significant factor contributing to the continued climb in firefighter deaths due to the lack of understanding of fire behavior in residential structures from natural ventilation and ventilation performed by firefighters.*

7. Depending on the size of the house, firefighters may have less then _____ minutes from the time of ventilation until conditions become untenable.*

8. TRUE or FALSE. Unless water is applied to the fire, opening more windows simply causes the fire to grow faster and flashover to occur sooner because of the new flow paths that are created.*

9. TRUE or FALSE. Across all experiments, conditions in the closed bedroom remained tenable for temperature and oxygen concentration thresholds.*

10. TRUE or FALSE. If a fire is ventilated far away from the seat of the fire, it does not significantly increase temperature and create a flow path for the fire to previously uninvolved areas.*
