Question 1

anchor point

Answer 1

An advantageous location, usually a barrier to fire spread, from which to start constructing a fireline. The anchor point is
used to minimize the chance of being flanked by the fire while the line is being constructed.

Question 2

control line

Answer 2

An inclusive term for all constructed or natural barriers and treated fire edges used to contain a fire.

Question 3

fireline

Answer 3

The part of a containment or control line that is scraped or dug to mineral soil.

Question 4

modpup

Answer 4

Extinguishing or removing burning material near control lines, felling snags, and trenching logs to prevent rolling after an
area has burned, to make a fire safe, or to reduce residual smoke.

Question 5

contained

Answer 5

The status of a wildfire suppression action signifying that a control line has been completed around the fire, and any
associated spot fires, which can reasonably be expected to stop the fire’s spread.

Question 6

controlled

Answer 6

The completion of control line around a fire, any spot fires, and any interior islands to be saved. Burn out any unburned
area adjacent to the fire side of the control lines. Cool down all hotspots that are immediate threats to the control line,
until the lines can reasonably be expected to hold under the foreseeable conditions

Question 7

chain

Answer 7

Unit of measure in land survey, equal to 66 feet (20 M) (80 chains equal 1 mile). Commonly used to report fire
perimeters and other fireline distances. Popular in fire management because of its convenience in calculating acreage
(example: 10 square chains equal one acre).

Question 8

smoldering

Answer 8

Fire burning without presence of flame or
direct flame and barely spreading

Question 9

creeping

Answer 9

Fire burning with a low flame and slowly spreading

Question 10

RUNNING

Answer 10

Behavior of a fire spreading rapidly with a
well-defined head.

Question 11

spotting

Answer 11

Behavior of a fire producing sparks or embers that
are carried by the wind and which start new fires
beyond the zone of direct ignition by the main fire.

Question 12

torching

Answer 12

The burning of the foliage of a single tree or a small
group of trees, from the bottom up

Question 13

flare-up

Answer 13

Any sudden acceleration in the rate of spread or
intensification of the fire. A flare-up is of relativity short
duration and does not change existing control plans

Question 14

fire whirl

Answer 14

Spinning vortex column of ascending hot air and
gases rising from a fire and carrying aloft smoke,
debris, and flame.

Question 15

backing

Answer 15

That portion of the fire with slower rates of fire
spread and lower intensity, normally moving into
the wind and/or down slope.

Question 16

flaming front

Answer 16

That zone of a moving fire where the combustion
is primarily flaming.

Question 17

crowning

Answer 17

A fire that advances from top to top of trees or
shrubs more or less independent of a surface fire

Question 18

fire triangle

Answer 18

oxygen, heat, and fuel

Question 19

methods of heat tranfer

Answer 19

convection: The transfer of heat by the movement of a gas
or liquid.

conduction: The transfer of heat through direct contact

radiation: Transfer of heat in a straight line through a gas or
vacuum other than by heating of the intervening space

Question 20

Stronger winds at night will

Answer 20

Keep temperatures warmer and RH low.

Question 21

South-facing slopes are typically

Answer 21

Warmer and drier than north-facing slopes

Question 22

Which of the following correctly explains cloud cover at night?

Answer 22

Keeps surface temperatures warmer than would otherwise be expected
