# Chapter 12 ISO at Structure Fires Flashcards

1
Q

Define building geometry

A

The constellation of elements that must be taken into consideration at a structure fire, including issues associated with the buildings layout, size, number or floors, access options, and other features.

2
Q

Define High rescue profile

A

A classification indicating a high likelihood that a person located within a fire-involved structure can be successfully rescued

3
Q

Define Marginal rescue profile

A

A classification indicating a moderate likelihood that a person located within a fire involved structure can be successfully rescued; in this scenario, there is clear danger to occupants and rescuers but no compelling evidence to indicate a high or zero rescue profile

4
Q

Define personnel accountability report (PAR)

A

An organized reporting activity designed to account for all personnel working an incident. To be truly effective, it should include radio transmissions that include confirmation of the assignment, location, and number of people in each assignment

5
Q

Define rescue profile

A

A classification of the probability that a victim will survive a given environment within a given building space or compartment.

6
Q

3 levels of rescue profiles

A

High, marginal, zero

7
Q

What is the Read 3 skill set?

A

8
Q

What is the risk taking formula?

A

principle hazards +/- integrity + other hazards +/= resource effectiveness = risk taking

9
Q

What are the two components that can minimize risk taking?

A

environmental integrity and resource effectiveness

10
Q

issues associated with the buildings layout, size, number of floors, access options, and other features

A

Building geometry

11
Q

What are the principle hazard categories at a structure fire?

A

hostile fire events
Building geometry
Collapse potential
Hazardous energy

12
Q

The status of the building, conditions, and hazards in terms of stability (change potential) and time (rate of change)

A

Environmental intergrity

13
Q

What are the 4 ways environmental integrity is defined?

A

Stable not likely to change = subtracts
Stable slowly changing = may or may not subtract
Unstable changing slowly = adds to risk taking
Unstable changing quickly = exponentially adds to risk

14
Q

When the ISO surveys the entire area of incident impact what should they ensure crews have?

A

2 escape areas

Clear corridor for egress

15
Q

What is the recommended staff total for high hazard occupancy?

A

42

16
Q

What is the recommended staff level for medium hazard occupancy?

A

30

17
Q

What is the recommended staff level for low hazard occupancy?

A

23

18
Q

Over how many feet present unique concerns regarding reach

A

300 feet

19
Q

Classification given to the probability that a victim will survive a given environment within a given building space or compartment

A

Rescue profile

20
Q

Spaces within a building where a victim would be in danger of harm from the incident and the likelihood of survival is good with a rescue effort

A

High rescue profile

21
Q

Under what temperature does water show rivulets slowly moving down the inside of the glass (condensation) which can be survivable space?

A

160F

22
Q

What are some visual indicators of a high rescue profile?

A
```clear windows above or near active fire
Minimally smoke-stained windows
Visible interior blinds
Condensations on inside of windows
Obvious smoke thermal balance```
23
Q

Spaces within the building that present a danger to occupants and rescuers bt there is no compelling evidence to indicate a high or zero rescue profile

A

Marginal rescue profile

24
Q

Indicators of a marginal rescue profile

A

fast, thick, dark smoke leaving a space that is not turbulent and not filled the space
intact dark stained windows that have no heat stress cracks
spaces that experienced a collapse but did not become fire involved

25
Q

Spaces or areas where conditions are simply not survivable

A

Zero rescue profile

26
Q

Indicators of zero rescue profile

A

Turbulent black and super dense smoke filled the given space
Deeply stained windows with long smooth heat stress cracks
Areas that have floor level temperatures over 300f
Areas that experienced collapse and rapid fire involvement

27
Q

What is a PAR?

A

Organized reporting activity designed to account for all personnel working at an incident

28
Q

What events should trigger a PAR?

A

operational mode change
incident benchmark has been achieved
Report or witnessing a flashover or collapse
After a report of missing or trapped firefighters

29
Q

When should a ASO be considered?

A

Large buildings with significant fire involvment
When plans section is established
Fires in building with unusual or unique hazards
When ISO is requested inside the IDLH
When mayday declared and RIC activated

30
Q

What information should be shared between RIC leader and ISO?

A
```Locations of interior crews
Fire behavior issues
Access/egress options
Building construction collapse threats
Hazardous energy issues```
31
Q

In a building with a central hallway and stairwell what is the number one tactical priority?

A

Controlling smoke and heat for search. fire attack, and firefighter safety

32
Q

What is usually the cause of commander dysfunction?

A

Incomplete or inaccurate incident intelligence
Failure to update the IAP to address changing conditions
Inexperience of the IC
