A

Peak cut

17
Q

The use of positive-pressure fans to control the flow of products of combustion while fire suppression efforts are underway.

A

Positive-pressure attack

18
Q

Ventilation that relies on fans to push or force clean air into a structure after a structure fire has been controlled.

A

Positive-pressure ventilation

19
Q

The main ventilation opening made in a roof to allow smoke, heat, and gases to escape.

A

Primary cut

20
Q

The membrane, which may also be the roof assembly, that resists fire and provides weather protection to the building against water infiltration, wind, and impact.

A

Roof covering

21
Q

The rigid portion of roof between the roof supports and the roof covering.

A

Roof decking

22
Q

An additional ventilation opening made for the purpose of creating a larger opening or limiting fire spread.

A

Secondary cut

23
Q

A ventilation opening that is usually about 8 ft by 4 ft (1.2 m by 2.4 m) in size; it is primarily used for large commercial buildings with flat roofs.

A

Seven, nine, eight (7,9,8) rectangular cut

24
Q

A mechanical device, similar to a large fan, that can be used to force heat, smoke, and gases from a post-fire environment and draw in fresh air.

A

Smoke ejectors

25
Q

The condition in which smoke hangs low to the ground because of the presence of cold air.

A

Smoke inversion

26
Q

The process of striking a roof with a tool to determine where the roof supports are located.

A

Sounding

27
Q

Another term for a trench cut.

A

Strip cut

28
Q

The vertical air flow within buildings caused by the temperature-created density differences between the building interior and exterior or between two interior spaces.

A

Stack effect

29
Q

An offensive fire attack initiated by an exterior, indirect handline operation into the fire compartment to initiate cooling while transitioning into interior direct fire attack in coordination with ventilation operations.

A

Transitional attack

30
Q

A roof cut that is made from one load-bearing wall to another load-bearing wall and that is intended to prevent horizontal fire spread in a building.

A

Trench cut

31
Q

A triangle-shaped ventilation cut in the roof decking that is made using a saw or an axe.
