BOOK 99 BRUSH FIRE OPERATIONS MANUANL CHAPTER 3 BASIC OPERATIONS Flashcards
The method used to construct the line will vary depending on the _____ and ____ of the fire, ______ involved and the method of attack, _____ or _____.
Location and size
Terrain
Direct or indirect
an unfinished preliminary control line made as an emergency action to check the spread of the fire, and to establish control of the perimeter.
A scratch line
A scratch line is only an aid in quick control of the fire and will have to be _______ as soon as possible.
Cold trailed
is a firebreak that is wide enough for permanent control that can be used in a direct or indirect attack.
A control line
______ a fire control line must begin as soon as the line is established and must continue until the fire is “dead out”.
Patrolling
As you patrol, mark the hot spots with _______ ___ _____, stack of rocks, etc., so your relief will know what to look for and where.
Fire line tape
if it’s anticipated that tap-ins will be needed, then consideration should be given to reducing friction loss by using __” hose between the apparatus and fire control line anchor point.
1 1/2”
The use of the __” hose as a brush firefighting line is not recommended.
1 3/4”
Consideration should be given to using 1¾”, or larger diameter hose as
Supply lines
This is the preferred method of use for steep terrain or heavy brush.
Hose Rolls
Members are spaced along the existing line, and use a “_____ _____” method of passing hose and equipment along the line to the end.
Bucket brigade
He/she pulls a second dry line of hose parallel to the wet line to be extended. Other members fall in and drag the dry line towards the nozzle.
Wet Line/Dry Line Method
In this method of extension, hose is added to the firefighting line at the apparatus. When the line needs to be extended, the Engineer will connect additional sections of hose to an unused outlet
Continuous Line Method
The remaining water in the hose will provide head pressure at the nozzle allowing it to be used while the line is being extended.
DOWNHILL EXTENSION:
requires members to drag loaded hose uphill through the brush.
UPHILL EXTENSION:
Department helicopters can be used effectively to transport, deploy, pick up or reposition hose lines as a sling load operation.
Pulling Hose With Helicopters
Hose pulling operations will normally be conducted by _______ personnel with the assistance of ground fire personnel.
Helitac
- Connect the nylon hose pulling sling to the hose. This is accomplished by:
a. Taking a bight of hose ___ to ___ feet from the end.
15 to 20
Relay
- Lay lines “_____ _____”. This method will eliminate much of the confusion and will deliver the water quicker.
Caravan style
On flat terrain, all pumps will maintain ___ psi engine pressure using their gate pressure gauge.
180
Swimming Pool Auxiliary Water Supply (S.P.A.W.S.) ystem is comprised of ___________feet of four inch ____ ____ _____ and appropriate fittings to provide as much flexibility as possible, enabling companies to access water resources that were previously inaccessible.
One hundred ten feet
White pvc pipe
In most cases the S.P.A.W.S. system can be deployed by a Task Force in less than
10 mins

Hack saw
The S.P.A.W.S. system may be transported via an _________, Department Helicopter or the Stake Bed truck assigned to the Valley Shops at Fire Station 88.
Aerial ladder truck
When the S.P.A.W.S. system is transported via a Department helicopter the pipe is placed across the floor of the aircraft centered side to side. When flying the sliding doors remain open, and the airspeed of the helicopter is limited to __ knots.
80 knots
To load the pipe bundle into the aircraft remove the two __ foot sections from the bundle and re-secure the straps.
5
The S.P.A.W.S. system may be loaded into the stake bed truck by first removing the ____ foot sections of the pipe and re-securing the bundles. Load the bundles onto the truck and tie down with _____rope.
5 foot
Drop bag rope
7” lift
600 gpm time required to prime: ____ seconds
10” lift
550 gpm time required to prime: ___seconds
15” lift
400 gpm time required to prime: ___ seconds
40 seconds
45 seconds
60 seconds
is a drastic measure that is to be employed only in extreme emergencies.
Burning grass or brush to create a firebreak.
Backfiring
This phase is the same as overhauling at a structure fire.
Coldtrailing
A well constructed coldtrail is _____and _____ of the burn.
Half in and half out
Coldtrailling
Authorities recommend a width somewhere between the same ____ as the brush and ____ the height of the brush, depending on the terrain, wind, etc
Same height
And twice height
In order to prevent burning or smoldering objects such as cactus, pineapples, logs etc. from rolling downhill past the fireline, it is necessary to _____ below them.
Trench
In selecting tools for coldtrailing, the most overlooked tool is the
Mccloud
the McCloud is more reliable than a _____ and faster than a _____.
Hose line
Shovel
The ______________ is more versatile than the McCloud, does a good job, and should be available on all firelines.
Round point shovel
A member who uses a shovel often learns that the worst thing for a shovel blade is
Paint
If you must paint your shovels, spray on a thin coat of
Aluminum paint
To organize your crew into a “coldtrailing team.” The first member, often referred to as the “______,” has the job of cutting the heavy limbs and brush.
Pioneer
The second member, called a “_____,” removes all of the loose limbs and throws these and the brush cut by the pioneer deep into the burn.
Thrower
The third member finishes cutting the prescribed width of the trail, and scrapes to mineral earth removing ____ and _____
Duff and leaves
