When Salvaging Household Furnishings and Commercial

Stock

16


Stock

• Removing large quantities of water by:– Cleaning clogged drains.– Removing toilet fixtures.– Creating scuppers.– Using existing sanitary piping

systems.– Affixing chutes.


17

• Reinforced corners and hems.• Purpose of grommets in the edge

hems.• Difficulty of adapting plastic covers

to traditional salvage cover folds.


18


19

Salvage Equipment Location

• Why is it recommended that salvage equipment be located in one area on the apparatus?– Eliminates the need to search the

apparatus for equipment.


20

Salvage Equipment Location

• How should smaller tools and equipment be stored on the apparatus?– In a specially designated salvage tool

box or other container to make them easier to carry.


21


22

Maintenance Of Salvage Covers

• The proper cleaning, drying, and repairing of reusable salvage covers increases their span of service.


23

Maintenance Of Salvage Covers

• Rinse with a hose stream.• Scrubbing with a brush and mild

soap and water for heavy soiled areas.

• Rinse.• Allow to air dry.• Inspect for damage.


24


25


26

Salvage Equipment

• Wrenches, pliers, screwdrivers.• Plastic, knife, nails, screws, duct tape.• Hammers, staple gun, pry bar.• Squeegees, brooms, water vacuum.• Scoop shovels, debris buckets.

Equipment based upon local service area needs!!!


27

Methods Of Folding, Rolling, and Spreading Salvage

Covers

• One firefighter spread with a rolled salvage cover.

• One firefighter spread with a folded salvage cover.

• Two firefighter spread with a folded salvage cover.

32

Water Chutes

• Salvage covers can be used to create water chutes to direct water out of a structure to prevent further damage to the building and its contents.


33


34


35


36

Construction Of A Catchall

• A catchall can be constructed from a salvage cover and placed on the floor to catch water. They can hold up to a couple hundred of gallons of water.


37


38


39

Covering Openings

• Cover all exterior openings to help prevent further damage to property by weather.

• Cover broken or missing doors or windows with plywood, heavy plastic, and/or similar materials.


40

Covering Openings

• Cover openings in roofs with plywood, roofing paper, heavy plastic sheathing, or tar paper.

• If using roofing paper, tar paper, or plastic, use appropriate roofing nails to tack down the edges with laths between the nails and the material.


41


42

Overhaul

• Is it necessary to wear self-contained breathing apparatus (S.C.B.A.) when performing overhaul?– YES!!! It is essential for firefighters to

wear proper personal protective equipment (P.P.E.), including S.C.B.A.; eye protection should be worn if it is safe to remove self-contained breathing apparatus.


43

Overhaul

• What size hoseline do you need for overhaul?

• What kind of appliances may be used to extinguish small fires during minor overhaul operations?

• What should firefighters do with the hoseline during overhaul operations to prevent water damage?


44

What Other Tools Will Be Needed For Overhaul?


45

What Is The First Step In Overhaul?

• Determine if the condition of this building is safe to perform overhaul?


46

What Two Major Factors Affect The Condition Of The

Building?

• Fire intensity and amount of water used!


47

What Are Some Signs Of Structural Instability?

• Weakened floors.• Spalled concrete.• Weakened steel roof members. • Offset walls due to elongated steel

supports.• Opened mortar in wall joints.• Melted wall ties.


48

What Is The Second Step In Overhaul Operations?

49

Utilize Senses To Search For Hidden Fires

• Touch– Feel walls and floors for heat with the back

of a ungloved hand.

• Sound– Popping or cracking of fire burning.– Hissing of steam.

• Electronic Sensors– Thermal (heat) signature detection.– Infrared signature detection.


50

When May The Process Of Looking For Extension and

Hidden Fires Begin?

• After the fire has been knocked down and the person responsible for determining the cause and origin of the fire says that it is all right.


51

Where Does The Process Of Looking For Hidden Fires

Begin?

• In the area of actual fire involvement. This will extend away from the area of origin to the area above the fire, below the fire, and to all sides of the fire.


52

What Are The Four Basic Methods Of Detecting Hidden

Fires?

• Sight• Touch• Sound• Electronic Sensors


53

What Are Some Ways Firefighters Can Detect Hidden Fires By Sight?

54

What Are Some Ways Firefighters Can Detect Hidden

Fires By Touch?

• Feeling walls with back of ungloved hand.


55

What Are Some Ways That Firefighters Can Detect Hidden

Fires By Sound?

• Listening for popping or crackling of fire burning, listening for hissing steam.


56

Use Of Electronic Sensors

• They use a laser to detect a temperature of an object, such as a wall. With a higher than normal temperature may indicate a hidden fire. A Thermal Imagining Camera (T.I.C.) would also work in much the same way.

61

Methods Of Checking For Fire Extension and Hidden Fires

• If floor beams are burned at their ends where they enter a party wall, flushing voids in wall with water and check the far side of the wall for hidden fire.

• Removing, checking, and extinguishing insulation materials.


62

Methods Of Checking For Fire Extension and Hidden Fires

• If fire has burned around doors and windows, opening door and window casings and extinguishing fires.

• If fire has burned around a combustible roof or cornice, opening the cornice and inspecting for hidden fires.

• If sensory equipment indicates, remove materials and check for hidden fires.
