20
Q

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

A

Primary cut

21

Q

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

A

Sounding

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. (NFPA 92)

A

Stack effect

29
Q

Another term for a trench cut.

A

Strip cut

30
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

31
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

32
Q

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

A

Type I construction

34
Q

The type of construction in which the fire walls, structural elements, walls, arches, floors, and roofs are of approved noncombustible or limited-combustible materials without fire resistance.

A

Type II construction

35
Q

The type of construction in which exterior walls and structural elements that are portions of exterior walls are of approved noncombustible or limited-combustible materials and in which fire walls, interior structural elements, walls, arches, floors, and roofs are entirely or partially of wood of smaller dimensions than required for Type IV construction or are of approved noncombustible, limited-combustible, or other approved combustible materials. (NFPA 14)

A

Type III construction

36
Q

The type of construction in which fire walls, exterior walls, and interior bearing walls and structural elements that are portions of such walls are of approved noncombustible or limited-combustible materials.

Q

The type of construction in which structural elements, walls, arches, floors, and roofs are entirely or partially of wood or other approved material. (NFPA 14)

A

Type V construction

38
Q

The controlled and coordinated removal of heat and smoke from a structure, replacing the escaping gases with fresh air. (NFPA 1410)

A

Ventilation

39
Q

A fire in which the heat release rate and fire growth are regulated by the available oxygen within the space. (NFPA 1410)

A

Ventilation-limited fire

40
Q

The vertical venting of structures involving the opening of bulkhead doors, skylights, scuttles, and roof cutting operations to release smoke and heat from inside the fire building. (NFPA 1410)
