Q

The ISO should request an ASO at wildland fires in certain circumstances:

A
  • Fires that impact a widespread geographical area
  • When a plans section is established.
  • Fires that are active for more than four hours.
  • Anytime a base camp is established.
25
Q

What should structural firefighters engaged in wildland fire practice during the incident?

A

Back off from their typical pace.

26
Q

Who can help with recon in the wildland fires, and their reports are important not only to the ISO but to the IC as well?

A

ASOs or lookouts

27
Q

If an elevated feature affords a good sight line,

A

take advantage of it as long as there is no remote possibility that the fire will go there.

28
Q

What are the purposes of recon at a wildland incident?

A

To define the principal hazard, judge the potential for environmental change (integrity), define the impact of the physical surrounding, and equate the exposure of crews to the environment and principal hazard.

29
Q

The principal hazard in most wildland environments can result from one of three causes:

A
  • rapid fire spread
  • traffic issues
  • physical exertion
30
Q

LACES

A

Lookouts, awareness, communications methods, escape routes, safety zones

31
Q

What is an important rapid withdrawal option that is essential for rapid retreat in the wildfire environment?

A

Backing apparatus into dead-ends, driveways, and structural protection assignments.

32
Q

What are the general ISO duties that apply at the wildland fire?

A

monitoring risk, operational effectiveness, and personal safety systems.

33
Q

Which is NOT one of three causes for the principle hazard in most wildland environments?

A

Fire reburn

34
Q

What is the act of intentionally being hit by the fire

retardant being dropped from an aircraft which can result in firefighter injury?

A

Sliming

35
Q

What is the short-lived sudden rise in fire intensity?

A

Flaring

A

Type 3

37
Q

At what wildfire flame length can the fire generally be

attacked directly using hand lines and tools?

A

Less than 4 feet

38
Q

Smoke obscuration

39
Q

Which physical surrounding hazard tops the list at

wildland fire incidents?

A

40
Q

Which is a large campaign-type wildfire that requires the
coordination of a significant number of interstate and
federal resources?

A

Type 1

41
Q

What is the time window for effectiveness at a wildland

fire usually measured in?

A

Minutes and hours

42
Q

What should be evaluated if after the initial adrenaline
has worn off the firefighters are NOT showing the same
energy at the wildfire incident?

A

Rehab operations

43
Q

Which type of wildland fire requires regional mutual aid
and specialized state and federal resources for
containment and extinguishment?

A

Type 3

44
Q

How long could it take to make a structure defensible

against an advancing fire?

A

20 to 30 minutes

45
Q

What should the rehab attendants consider for any
firefighter who exhibits signs of possible heat stress at
the wildfire incident?

A

Cardiac monitoring

46
Q

After what length of time of active fire at the wildland

fire incident should the ISO request an ASO?

A

4 hours

47
Q

Approximately how long should a fit firefighter be able to

work hard with effective rehab at a wildfire?

A

10- to 12-hours

48
Q

Which is an effective way the ISO can take a tour of the

A

Helicopter

49
Q

Which type of wildland fire exceeds the resource
capabilities of initial responders but is manageable with
additional resources?

A

Type 4

50
Q

Which is generally a safe zone for the firefighter at a

wildfire incident?

A

Burn

51
Q

What can be done to remind drivers to use spotters when

driving small, mobile brush patrol vehicles?

A

Broadcast a general safety message over the radio

52
Q

Which class foam is used in wildland environments?

A

A

Which type of wildland fire can be contained and

extinguished with local initial responders?

A

Type 5

54
Q

What acronym is used to address rapid withdrawal options?

A

LACES

55
Q

What is the wildland fire term used to describe the sudden advancement and increase in fire intensity due to wind?

A

Blow-up

56
Q

Which is the interpretation that should be made when the

wildfire flame length is 4 to 8 feet?

A

The fire is too intense for a direct attack method.

57
Q

What happens to active firefighting operations at a

wildfire incident at dark?

A

Suspend them

58
Q

Which is NOT top on the list of factors that require

significant attention to rehab at the wildfire incident?
