4. Open fire room doorway
5. Outlet opening

Question 2

When an outlet opening is then created in the structure, the__will flow to
the ___ opening creating a flow path through the structure creating

In past wind-driven fires, flow paths have traveled ___, and
downwards through structures.

Answer 3

suddenly and create an untenable environment with floor-to-ceiling
temperatures in excess of ___ along the flow path.

Answer 4

1500F

should attack the fire directly. An ___ tactic should
be implemented:

Answer 12

indirect fire suppression

Question 13

Research shows the fire behavior throughout the flow path will quickly
decrease and temperatures will drop by__ within 20-30 seconds
