A

The conditions and communicates with the firefighters on the hose line. (17)

21
Q

If water is being placed on the fire the door control firefighter should do what?

A

22
Q

When educating firefighters on ventilation what is of the utmost importance?

A

Recognize the door as a vent opening. (17)

23
Q

Whatever method a department chooses to control flow path, most of all it should what?

25
Q

What is the ultimate goal with ventilation?

A

Control the building and make it behave in a manner that is safest for firefighters and civilians. (20)

26
Q

How is ventilation achieved?

A

By controlling the openings and limiting the amount of air that is allowed into the fire until water is applied. (20)

27
Q

Door control is vital to the success of interior firefighting operations if what is not possible?

A

Coordinated ventilation. (21)

28
Q

When venting for fire when must the water be applied to the fire?

30
Q

Any hole in the building from the outside in or inside out is what?

A

Ventilation. (21)

31
Q

How must a firefighter maintain balance?

By creating an opening small enough to limit the oxygen to the concealed space, but large enough to flow adequate water to cool the environment and eventually extinguish the fire. (22)

32
Q

Ventilation must be timed with what?

A

Water application. (22)

33
Q

How do we keep fire in a ventilation limited stage?

A

Identifying the openings or places where the fire is receiving its oxygen and trying to control those openings. (22)

34
Q

Every tactic on the fire ground that is completed is also what?

A

Ventilating the building (22)

Venting the building (22)

36
Q

All of the doors failed at approximately what?

A

5 min. (23)

38
Q

The two legacy windows with single glazing failed when?

A

Later than the four modern windows with double glazing. (23)

39
Q

What had no noticeable impact on failure time?

41
Q

A

A piece of rubber tire or a carpentry clamp

43
Q

A

Elevation

Slowing

44
Q

How do draft curtains help facilitate the goal of containing the fire to the room of origin?

A

By keeping the fire rich until ventilation can be coordinated.

45
Q

Failure of the window was defined as passage through the window of what percentage or more of the total glass area

A

25%

46
Q

In most cases the failure of the window was where

A

Top or bottom pane

47
Q

Two reasons the legacy windows failed later in the modern windows
