Q

The process of predicting collapse at an actual incident becomes a cyclic activity that is akin to an algorithm. What are the four analytical inputs the algorithm uses?

A

1) Classifying the
CONSTRUCTION
2) Determining structural
INVOLVEMENT
3) Visualizing and tracing
LOADS
4) Evaluating elapsed TIME

Collapse will C.I.L.T us

20
Q

When discussing building collapse, these types of buildings are basically losers during fires, should be treated as collapse-ready and a defensive strategy should be pushed for?

A
  • Buildings undergoing
    construction
  • Buildings undergoing
    demolition
  • Buildings undergoing
    extensive remodeling
21
Q

What is an appropriate collapse zone for wood structures but may not be adequate for unreinforced masonry construction?

A

At least 1.5 times the height of the element that is anticipated to fall P. 279

(mentions falling unreinforced masonry wall propelling bricks 3 times the height of the wall)

22
Q

Closely related to the fireground clock is judgment on _____ . The 360° building size up provides an opportunity to gauge smoke changes. Simply applied, is the smoke getting better or worse,
in seconds or in minutes?

A

Rate of Change

23
Q

The judgment about what two items can help the fire officer understand the time window that is available (or not available) for safe INTERIOR operations?

A
  • Rate of Change
    (combined with)
  • Fireground Clock
24
Q

This use type is for those buildings that are used for civic or societal needs. Schools, jails courts, hospitals and other human service facilities are included.

A

Institutional

25
Q

This use type is for buildings used for the purpose of human gathering that present the risk of large loss of life when fire strikes. Some of the most stringent (fire resistive) building coded have been developed for public assembly occupancies to help prevent the reoccurrence of large loss-of-life tragedies that have scarred our histories.

  • Stadium, theaters, churches (large)
  • Restaurants, churches (small/
    medium)
A

Public assemblies

26
Q

When a building has been judged occupied, the fire officer must look at smoke and fire conditions and make a further judgment about survivable spaces. The condition of ____ can help in making these survivable space judgment.

A

Windows

27
Q

This type of building are those that have outlived their usefulness, fallen into disrepair, and show signs that the owner has basically given up on the building

A

Abandoned

28
Q

Abandoned buildings present numerous challenges for Firefighters. These challenges include: (3)

A
  • Dangerous interior conditions
  • High potential for criminal related
    hazards
  • Potential for unlawful occupants
29
Q

A common marking system includes posting a sign with this to denote buildings that are too dangerous (structurally) for interior firefighting operations. These placards are usually accompanied by “No Trespassing”warning to others that the building will not be searched by Firefighters.

A

A large white “X” across a red background

30
Q

The combination of what two elements of building size up will help you form a strong impression of the CHALLENGES the incident will present?

A

Considerations and Status

uCSbc

31
Q

This is defined as once personnel arrive on scene, how long will it take to make a visible impact on the fire?

A

Fireground clock

32
Q

This is defined as once personnel arrive on scene, this is a combination of the time it will take to apply the first drop of water IN ADDITION to the time it will take for extinguishment.

A

PERCEPTION of fireground time

33
Q

This is defined as: is the smoke getting better or worse, in seconds or in minutes?

A

Rate of Change
(goes with fireground Clock)

34
Q

When discussing visual warning for signs of collapse, the author feels most of these signs are late warning signs. There are dozens of investigative reports where firefighters reported the building “collapse without warning”. A better process to predict collapse is?

A

By using a mental one. Branigan states the warning is the brain.

35
Q

When discussing forcible entry with the building sizeup factors or clues, the author suggest that forcible entry should be viewed as what?

A

A two-part operation that consist of forcible entry and forcible exit

36
Q

PRIORITIZING search is an exercise in combining which of our building size-up factors? (4)

A
  • Use (& size)
  • Status
  • Burning
  • Clock

no Construction

37
Q

Within the 6 Tactical Challenges, what are some of the special Hazards?
(efsvcH)

A
  • Hazmat
  • Hoarding
  • Overhead powerlines
  • Challenging access/egress
  • Previous fires and collapses
  • Aging/lack of maintenance
  • Windowless buildings
  • Multiple entry levels or sloping grade
38
Q

In addition to the specific hazards previously listed, the author feels there are significant GAME CHANGING hazards worthy of mention:

A
  • Base of operations
  • Green movement (solar/antennas)
  • Façades
  • Access/egress (exit other than front door)
  • Name/utilities
    (One of easiest size-up indicators - sign on front of building)
39
Q

Key to remembering the process of size up your next building is:

A

Unconscious competence

40
Q

In most organizations, the responsibility of reading the whole building after the first-due has gone to work is assumed by the incident commander. For the IC, ____ can limit the ability to continually read the building. For this reason, the author supports what to counteract those limits?

A
  • The strategic and stationary nature
    of the IC responsibilities
  • The designation of an Incident Safety
    Officer (ISO) or IC assistant who has
    the flexibility to roam the incident
    scene and continually read the
    building.
41
Q

Chief Joe Castro of the Los Angeles Fire Department uses two primary assessments for his fire triage and risk management program and they are:

A
  • When to consider NOT entering a
    building
  • When to consider GETTING OUT of a
    building
42
Q

The process of predicting collapse at an actual incident becomes a cyclic activity that is akin to an algorithm. The algorithm uses ___ analytical inputs and ___ important output.

A
  • 4 inputs (C.I.L.T.)
  • 1 output (predicting collapse)
43
Q

When using the algorithm for predicting collapse, what are the four inputs?

A

1) Classifying the CONSTRUCTION
2) Determining structural
INVOLVEMENT
3) Visualizing and tracing LOADS
4) Evaluating elapsed TIME

44
Q

When using the process of predicting collapse, which input is “imperative”?

A

Input 2) Determining structural involvement

45
Q

When referencing the five parts of building size up, which of them influence SEARCH CHALLENGES?

A
  • Use/size
  • Status
  • Fireground Clock

(No construction or burning)

46
Q

Search challenges versus prioritizing search?

A

Challenges: Use/size, Status, Fireground clock

Prioritizing: Use/size, Status, What’s burning, Fireground clock
