Chapter 12 ISO at Structure Fires

Question 1

Define building geometry

Answer 1

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.

Question 2

Define High rescue profile

Answer 2

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

Question 3

Define Marginal rescue profile

Answer 3

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

Question 4

Define personnel accountability report (PAR)

Answer 4

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

Question 5

Define rescue profile

Answer 5

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

Question 6

3 levels of rescue profiles

Answer 6

High, marginal, zero

Question 7

What is the Read 3 skill set?

Answer 7

read smoke, read building, read hazardous energy

Question 8

What is the risk taking formula?

Answer 8

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

Question 9

What are the two components that can minimize risk taking?

Answer 9

environmental integrity and resource effectiveness

Question 10

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

Answer 10

Building geometry

Question 11

What are the principle hazard categories at a structure fire?

Answer 11

hostile fire events
Building geometry
Collapse potential
Hazardous energy

Question 12

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

Answer 12

Environmental intergrity

Question 13

What are the 4 ways environmental integrity is defined?

Answer 13

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

Question 14

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

Answer 14

2 escape areas

Clear corridor for egress

Question 15

What is the recommended staff total for high hazard occupancy?

Answer 15

42

Question 16

What is the recommended staff level for medium hazard occupancy?

Answer 16

30

Question 17

What is the recommended staff level for low hazard occupancy?

Answer 17

23

Question 18

Over how many feet present unique concerns regarding reach

Answer 18

300 feet

Question 19

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

Answer 19

Rescue profile

Question 20

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

Answer 20

High rescue profile

Question 21

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

Answer 21

160F

Question 22

What are some visual indicators of a high rescue profile?

Answer 22

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

Question 23

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

Answer 23

Marginal rescue profile

Question 24

Indicators of a marginal rescue profile

Answer 24

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

Question 25

Spaces or areas where conditions are simply not survivable

Answer 25

Zero rescue profile

Question 26

Indicators of zero rescue profile

Answer 26

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

Question 27

What is a PAR?

Answer 27

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

Question 28

What events should trigger a PAR?

Answer 28

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

Question 29

When should a ASO be considered?

Answer 29

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

Question 30

What information should be shared between RIC leader and ISO?

Answer 30

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

Question 31

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

Answer 31

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

Question 32

What is usually the cause of commander dysfunction?

Answer 32

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