Q

In order for a ventilation limited fire to grow, it needs a new supply of

A

Oxygen

61
Q

________ refers to the rapid transition from the growth stage or early decay stage to a ventilation limited, fully developed stage

A

Rapid fire development

62
Q

A significant indicator of flashover is

A

Rollover

63
Q

Rollover is distinguished from Flashover because it involves only the fire gases at the

Lower levels of the compartment
Upper levels of the compartment
No gasses

A

upper levels of the compartment

64
Q

How does rollover contribute to flash over conditions?

A

The burning gases at upper levels of room generate tremendous amount of radiant heat, transfers to other fuels in the room

65
Q

Changes in ventilation can alter the ventilation ____ and create rapidfire development, placing firefighters in extreme danger

Flow path
Exit
Entry

A

Flow path

66
Q

Air intake
Air vents
Ventilation

A

Ventilation

67
Q

When a fire is in ventilation-limited decay, the introduction of new oxygen can trigger what

Flashover
Roll over
Pyrolysis

A

Flash over quickly

68
Q

What can occur whenever sufficient oxygen, and ventilation are available for Fire growth

Flashover
Rollover
Growth

A

Flashover

69
Q

____ May not occur in every compartment fire, such as a large area, compartment, or compartments with high ceilings

Flashover
Rollover

A

Flashover

70
Q

Observing this from the exterior of the structure, gives you a good indication of fire behavior within the structure

Ventilation
Levels of neutral plane
Heat

A

Levels of neutral plane

71
Q

This may indicate that the fire is in the early stages of development. Remember that high ceilings can hide a fire that has reached a later developed stage is can also indicate a fire above your level

High neutral plane
Mid-level neutral plane
Very low level neutral plane

A

High neutral plane

72
Q

This could indicate that the compartment has not yet ventilated or that flash over is approaching

high neutral plain
mid-level neutral plane
very low level neutral plane

A

Mid-level, neutral playing

73
Q

This may indicate that the fire is reaching Backdraft conditions. This occurrence could also mean that the fire is below you

high neutral plane
mid-level neutral plane
very low level neutral plane

A

Very low level neutral plane 

74
Q

An increase in low level ventilation, such as opening a door or window prior to upper level ventilation can result in an explosively rapid combustion of flammable gases called

Flashover
Backdraft
Bleve

A

Backdraft

75
Q

Backdraft occurs in the ____ stage in a space, containing a high concentration of heated flammable gases, but lacks sufficient oxygen for flaming combustion

Growth
Fully developed
Ventilation limited
Decay

A

The decay stage

76
Q

This condition can develop within a room, a void space, or an entire building

Backdraft
Flashover
Rollover

A

Backdraft

77
Q

Anytime, a compartment or space contains hot combustion products, firefighters must consider potential for backdraft before
