CROWN FIRES

20
Q

-occur on top of the trees

A

CROWN FIRES

21
Q

-they burn trees up their entire length to the top

A

CROWN FIRES

22
Q

-are considered the most dangerous fires and they spread the fastest

A

CROWN FIRES

22
Q

PARTS OF NATURAL COVER FIRE

A

HEAD
TAIL
FLANKS

22
Q

are started in advance of the heads by windows sparks on bits burning material.

A

SPOT FIRES

22
Q

is the point where the Fireline is progressing faster.

A

HEAD

22
Q

The withdraw or upward portion of the fire is called the?

A

TAIL

23
Q

METHODS FOR CONTROLLING AND EXTINGUISHING VARIOUS TYPES OF NATURAL COVER FIRES.

A

· SECTIONAL METHOD
· ONE- LICKED METHOD
· FIRE BREAKS
· BACKFIRES

23
Q

All portions of the fire lone between the tail and the various heads and those slower burning areas between the heads are called the?

A

FLANKS

24
Q

consists of placing a unit on a specific section of the Fireline.

A

SECTIONAL METHOD

25
Q
  • Its mission is to stop the progress of the fire, extinguishing it at the Fireline, and execute mop- up patrol work.
A

SECTIONAL METHOD

26
Q

-The unit has full responsibility for that section of the Fireline.

A

SECTIONAL METHOD

27
Q

-This method is best used against a slow- moving fire.

A

SECTIONAL METHOD

28
Q
  • It is the fastest and easiest method to use on a running fire.
A

ONE- LICKED METHOD

29
Q

-A team is placed at the location designated as the Fireline and ordered to work in a specific section.

A

ONE- LICKED METHOD

30
Q
  • Artificial firebreaks consist of roads, highways, survey lines, or cleared areas.
A

FIRE BREAKS

31
Q

are employed to burn back toward the advancing heads, thus creating a fast break and stopping the fire because of a lack of fuel.

A

BACKFIRES

32
Q

BASED ON CAUSE

A
  1. ELECTRICAL ACCIDENTS
  2. PURELY ACCIDENTAL CAUSES.
  3. NEGLIGENCE AND OTHER FORMS OF HUMAN ERROR.
33
Q

-The most common cause of a fire in a building is poor electrical wiring and faulty equipment

A

ELECTRICAL ACCIDENTS

34
Q

ELECTRICAL ACCIDENTS
-The most common cause of a fire in a building is poor electrical wiring and faulty equipment in the form of?

A

· SPARKING
· INDUCED CURRENT
· OVERHEATING OF ELECTRICAL APPLIANCES

35
Q
  • unusual or accidental connection between two points at different potentials.
A

SHORT CIRCUIT

36
Q
  • the production of sustained luminous electrical discharge between separated electrodes;
A

ARCING

37
Q

-an electric hazard that results when electrical current crosses the gap between 2 electrical conductors.

A

ARCING

38
Q
  • production of incandescent particles when two different potentials (charged conductors) come in contact;
A

SPARKING

39
Q

-occurs during short circuits or welding operations.

A

SPARKING

40
Q
  • Increased electrical energy flow or power voltage;
A

INDUCED CURRENT

41
Q

sudden increase of electrical current resulting to burning of appliances.

A

INDUCED CURRENT

41
Q
  • the increase or rising of amperage while electric current is flowing in a transmission line.
A

OVERHEATING OF ELECTRICAL APPLIANCES

42
Q

INTENTIONAL CAUSE

A
  1. ACCELERANT
  2. PLANT
  3. TRAILER
42
Q
  • the preparation and or gathering of combustible materials needed to start a fire.
A

PLANT

42
Q
  • highly flammable chemicals that are used to facilities flame propagation.
A

ACCELERANT

43
Q
  • the preparation of flammable substances in order to spread the fire.,
A

TRAILER
