SALVAGE
• To aid in reducing fire, water and smoke damage during and after fires.
• Identify the benefits of salvage.– Minimize losses– Build goodwill with publicBuild goodwill with public
PLANNING SALVAGE WORK
• Equipment inventory• Training– Procedures– Equipment– Timing of salvage operations
PLANNING SALVAGE WORK
• Arranging contents– Close piles– Group in center of room– Place high item in center– May not be possible in
commercial occupancies
PLANNING SALVAGE WORK
• Care and maintenance– Synthetic salvage covers• Rinse off• Dry (recommended, but not
necessary)• Fold
PLANNING SALVAGE WORK
• Canvas salvage covers– Wet with hose– Scrub with a broom– Rinse– Dry– Fold
PLANNING SALVAGE WORK
• Inspection– Have 3 or 4 firefighters line up along
one end of the salvage cover– Have them pass the salvage cover over
their heads and start walking towards the other end
– While walking, have the firefighters look up to detect any light shining through holes in the cover
– Have the firefighters mark any holes with chalk to be repaired
PLANNING SALVAGE WORK
• Cleaning of salvage equipment– Once cover is empty and brushed off, it
must be washed using a mild soap solution, and hung to dry.
• Maintaining salvage equipment– Salvage cover should be inspected for
holes and tears– Salvage cover should be repaired as
needed– Cover should then be folded and placed
back on the apparatus or in storage
USES AND CONSTRUCTION
• Water chute – Used to remove water– Create a water chute using salvage cover
and pike poles– Place chute on the lower floor under
firefighting effort, utilizing a ladder– Place one end of chute on ladder at an
angle higher than window, doorway or down a stairwell
– Place other end of chute out window, doorway or down stairwell for runoff
USES AND CONSTRUCTION
• Catchall – Using catchall to catch
water until water chute is created• Create catchall• Place on lower floor, under
firefighter efforts, to catch water until water chute is created
USES AND CONSTRUCTION
• Carryall – Using carryall to remove
debris• Heavy canvas
– Approximately 6 foot square– Has a rope strung through the
grommets for handles
USES AND CONSTRUCTION
• Salvage covers to remove debris – Fold cover into a loose fold and roll– By folding it on itself, debris will be trapped inside
to remove it where it is to be dumped
COVERING OR CLOSING OF BUILDING OPENINGS
• Windows/doors– Cover with plywood, heavy
plastic or similar materials to keep out rain
– Plywood, hinges, a hasp and a padlock can make a temporary door.
COVERING OR CLOSING OF BUILDING OPENINGS
• Floors/roofs– Cover with plywood, roofing
paper, heavy plastic sheeting or tar paper, using appropriate nails where applicable
– Mark the “holes/hazards”
Lay cover flat on the floor with one person at each end
One Person Roll
FOLDS & ROLLS
Grasp the cover with one hand midway between the center and the edge to be folded
Using the other hand as a pivot, pull tightly with the holding hand and bring the fold over toward the center
After the first fold has been placed at the center, grasp the open edge with the outside hand. Using the other hand as a pivot, stretch the cover
Bring this outside edge over to the center and place it on top and in line with the previously placed foldFold the other half of the cover in the same
manner by using steps 1, 2, 3 and 4
Fold over 12 inches at both ends
Start rolling at either end. Compress the first few rolls as tightly as possible
Tuck in slack at center if wrinkles appear while rolling
FOLDS & ROLLS
Two Person Roll
With the cover stretched lengthwise, both firefighters grasp opposite ends of the cover at the center grommet and then pull the cover tightly between them
Raise the center fold high above the floor and shake out the wrinkles to form the first half fold
Spread the half fold upon the floor, and smooth it flat to remove the
wrinkles
With a firefighter standing at each end of the half fold and facing the cover, grasp the open edge corners with the hand nearest to these corners. While in this position, place the corresponding foot at the center of the half fold and thus make a pivot for the next fold
Stretch that part of the cover being folded tightly between the firefightersMake the quarter fold by folding the open edges over the folded edges
One firefighter should stand on one end of the quarter fold while the other firefighter grasps the opposite end and shakes out the wrinkles
The firefighter holding the end of the cover then folds the quarter fold into one hand and carries this end to the partner
Both firefighters then grasps the open ends and use their inside foot as a pivot for the next fold
Both firefighters bring these open ends over and place them just short of the folded center
fold
The firefighters continue this folding process by The firefighters continue this folding process by bringing the open ends over and just short of the bringing the open ends over and just short of the folded end. During this fold, the free hand may be folded end. During this fold, the free hand may be used as a pivot to hold the cover straightused as a pivot to hold the cover straight
Both firefighters then crouch at each end of the lengthwise fold. The one at the fold forms a pivot with his hands. The other firefighter places the upper end
just short of the other end
The firefighters complete the operation by one more fold in the same manner. They bring the open ends over and to the folded end using the free hand as a pivot during the fold
• One person with a rolled cover– Start at one end of the object to be covered and
while still holding the roll in the hands, unroll it sufficiently to cover the end
DEPLOYING SALVAGE COVERS
– Lay the roll on the object and continue to Lay the roll on the object and continue to unroll toward the opposite endunroll toward the opposite end
Let the rest of the roll fall into place
Stand at one end and grasp the open edges
Open both sides by snapping both hands up and out
Open the other end in the same manner
DEPLOYING SALVAGE COVERS

OVERHAUL
• Overhaul is the practice of searching a fire scene to detect hidden fires or sparks, which may rekindle, and to note the possible point of origin and cause of fire.
METHODS USED TO DETECT HIDDEN FIRES
• Sight– Discoloration– Peeling paint– Smoke emitting from cracks– Cracked plaster– Rippled wallpaper– Burned areas
• Sound– Popping or cracking noises– Hissing of steam
METHODS USED TO DETECT HIDDEN FIRES
– Touch• Feel walls with the back of hand
– Electronic sensors• Thermal detection• Infrared detection
PRECAUTIONS & PROCEDURES• Wear proper PPE with SCBA where
applicable• Should be supervised by an officer not
directly involved in the overhaul operations
• Charged hose lines available• Evaluate structural integrity
– Weakened floors– Spalled concrete– Weakened steel– Weakened trusses– Weakened walls
RESTORATION OF THE PREMISES

• Secure the building– Cover roof openings– Cover doors and windows
• Release the premises to the owner– Done in front of witness
DUTIES OF PERSONNEL LEFT AT FIRE SCENE
• Guard the evidence where it is found, untouched and undisturbed, to preserve the chain of custody
• Properly identify, remove and safeguard evidence that cannot be left at scene of fire
• Control access
EXPOSING HIDDEN FIRES
• Ceilings– Position yourself between the area
to be opened and an escape route– Break plaster in the area to be
pulled– Use a pike pole or similar tool to
hook and pull the lath or wire mesh– Pull down and away
EXPOSING HIDDEN FIRES

the hole based on need• Sound for floor joists to decide the
exact location• Cut one side of the finished floor by
using angle cuts• Cut the other side of the finished floor
in a like manner
