Ch 4 Size Up Flashcards
_______ is a continuous process that actually begins before an incident is reported and continues throughout the incident
Size up
When considering the foundation for your decision making process, think about four components; facts, perceptions, and projections and_______
Probabilities
Construction type and_____dictate strategy and tactics
Occupancy
In addition to the construction types, materials, and structural weaknesses of a building, knowing the________ of the building will also improve the success and safety of rescuers at an incident
Layout
Tar, soot, and ______are the most common heated particles found in smoke, giving it the black color
Carbon
Light ________ Smoke indicates that pyrolysis is occurring in areas adjacent to the main body of fire
White
_______ wispy smoke can indicate pyrolysis in a compartment fire and should be considered unburned fuel
White
On cold days when the temperature is below freezing, smoke immediately turns ______ and turbulent on leaving the structure
White
_______ smoke is common in mid stage heating as moisture mixes with gases and carbon as pyrolysis increases
Brown
_______ smoke is an indication of burning wood, whether unfinished found largely in attic‘s, or finished as found in structural wood members
Brown
Black smoke contains high quantities of carbon particles and is also an indicator of the amount of ________ available at the seat of fire
Ventilation
Thin _____ smoke is the direct result of heat from a flame
Black
Thin, black smoke with smooth lines exiting high in an opening and going straight up indicates______ driven smoke with good ventilation
Flame
In addition to indicating the materials it is burning, thick, black smoke suggest the fire is in the late stages of _______, which produces large amounts of carbon as unburned product
Pyrolysis
_____ fire refers to dense, black smoke that is ready to ignite, possibly at the vent point
Black
A ______ Neutral plane may indicate that a fire is in the early stages of development
High
When the neutral plane is roughly centered between the ceiling and floor, the fire is beginning to be ________ controlled, and flashover conditions are developing
Ventilation
______ pushed smoke will usually flow, neither smooth nor turbulent
Volume
The darker and more ______ the smoke is, the closer you are to a rapid fire event
Turbulent
The movement of smoke can be described in terms of_____ and direction
Speed
The movement of smoke can be described in terms of speed and direction. When those two factors are considered at the same time, they are discussed in terms of ________
Velocity
Air movement is rapid and turbulent as a fire becomes_______ controlled
Ventilation
A rapid intake of fresh air can be an indicator of a fire reaching______ conditions
Flash over
A sudden in total rush of fresh air into a compartment can indicate that a______ condition is imminent
Backdraft
