Philosophy of Loss Control

• Minimize damage and provide customer service through effective mitigation and recovery efforts

• Builds goodwill

(Continued)


Salvage and Overhaul

• Most effective means of loss control

• Restoration of the property


Salvage

• Operations that aid in reducing primary and secondary damage during fire fighting– Primary damage is caused by the fire– Secondary damage is caused by fire

suppression activities

(Continued)


Salvage

• Both primary and secondary damage can be minimized through salvage

• Some damages cannot be avoided• Starts as soon as adequate

personnel are available• May be done simultaneously with

fire attack


Overhaul

• Consists of operations involved in searching for and extinguishing hidden or remaining fires

• Protecting the scene and preserving evidence are components of overhaul

(Continued)


Overhaul

• If possible, do not start overhaul operations until – Fire is under control– Fire cause has been determined– Evidence has been identified and

protected


Salvage

• Methods and operating procedures by which firefighters attempt to save property and reduce further damage– Removing property– Covering property– Other means

(Continued)


Salvage

• Proper salvage operations– Early planning– Knowing the procedures– Being familiar with tools and

equipment


Planning for Salvage Operations

• Efficient operations require planning and training

• SOPs should be developed

(Continued)


Planning for Salvage Operations

• Preincident plans– High-value contents– Residential occupancies– Commercial occupancies

• Work with loss-control representatives


Salvage Procedures

• Operations can be started at same time as fire attack

• Group building contents into compact piles

(Continued)


Salvage Procedures

• Group household furnishings in center of the room

• Raise furniture off wet floors

(Continued)


Salvage Procedures

• Commercial occupancies present special challenges

(Continued)


Salvage Procedures

• Large quantities of water can be removed by a variety of methods

• Water may ruin finishes; wipe off surfaces


Salvage Covers

• Made of waterproof canvas materials

• Manufactured in various sizes• Have reinforced corners and edge

hems

(Continued)


Salvage Covers

• Synthetic covers– Lightweight– Easy to handle– Economical– Indoor and

outdoor use

• Some covers may be disposable


Salvage Cover Maintenance

• Proper cleaning, drying, and repairing increases service life

(Continued)



• Canvas salvage covers– Wetting or rinsing with hose stream

and scrubbing with a broom– Detergent solution if needed– Don’t let dry when dirty– Should be completely dry before

being folded and placed in service

(Continued)



• Synthetic salvage covers– Do not require as much maintenance

as canvas– May be folded wet– Usually better to let dry first

• After salvage covers are dry, examine for damage

(Continued)



• Look up at the underside to locate holes– Mark holes with

chalk or marking pen

– Repair holes


Salvage Equipment

• Should be located in a readily accessible area on apparatus

• SOPs dictate where equipment is carried and who performs operations

(Continued)


Salvage Equipment

• Keep smaller tools/equipment in a salvage toolbox

• Plastic tub may be used for supplies


Typical Salvage Equipment

• Electrician’s pliers

• Sidecutters• Various chisels• Tin snips• Tin roof cutter• Adjustable

wrenches• Pipe wrenches

• Hammer(s)• Sledgehammer• Hacksaw• Crosscut handsaw• Heavy-duty

stapler and staples

automatic sprinkler systems– Used to stop flow of water from an

open sprinkler

(Continued)



• Carryalls — Used to carry debris, catch falling debris, and provide a water basin for immersing small burning objects

(Continued)



• Floor runners — Protect floor coverings; lightweight, tough, heat and water resistant, easy to maintain

(Continued)



• Dewatering devices– Used to remove water from basements,

elevator shafts, and sumps– Should not use fire department pumpers– Trash-type pumps are best for salvage– Use a jet-siphon device or submersible

pump for removal of excess water

(Continued)



• Water vacuum — Used to dewater floors, carpets, other areas where water is not deep enough to be picked up by submersible pump or siphon ejector

(Continued)



• J-hooks — Driven into walls or wooden framing to provide a strong point from which to hang things



• S-hooks — Used for the same purpose as J-hooks but cannot be driven into walls or framing; must have a horizontal ledge


One-Firefighter Spread with a Rolled Salvage Cover

• One person can quickly unroll a cover

• May be carried on the shoulder or under the arm


One-Firefighter Spread with a Folded Salvage Cover

• Two firefighters are needed to make fold

• May be carried in any manner


Two-Firefighter Spread with a Folded Salvage Cover

• Large salvage covers cannot be easily handled by a single firefighter

• Carry this fold on the shoulder with open edges next to neck

(Continued)



• Position cover so carrier can grab lower pair of corners and second firefighter can grab uppermost pair

(Continued)



• Balloon throw is most common method for deployment

(Continued)


Using Chutes: Removing Water

• Practical way to remove water that comes through the ceiling from upper floor

• May be constructed on floor below fire fighting operations (Continued)


Using Chutes: Removing Water

• Prepared chutes are approximately 10 feet (3 m) long

• Chutes can be constructed from plastic sheeting, a heavy-duty stapler, and duct tape


Using Chutes: Constructing a Catchall

• Constructed from a salvage cover placed on the floor to hold small amounts of water

(Continued)


Using Chutes: Constructing a Catchall

• Temporarily control large amounts of water

• Place into position as soon as possible

• Usually requires two people


Splicing Covers

• Used when:– Objects/groupings are large– Long chutes or catchalls need to be

made

• Splice covers with watertight joints

(Continued)


Splicing a Chute to a Catchall

• Method of removing accumulated water should be prepared

• Submersible pumps may be used• Water chute spliced to the catchall


Covering Openings

• One of final parts of salvage operations

• Prevents damage by weather

(Continued)


Covering Openings

• Cover doors/windows• Cover openings in roofs


Overhaul

• Operations conducted once main body of fire has been extinguished– Searching for and extinguishing

hidden or remaining fire– Placing building and contents in safe

condition

(Continued)


Overhaul

• Operations conducted once main body of fire has been extinguished– Determining fire cause– Recognizing and

preserving evidence of arson


Safety During Overhaul

• Steps required– Inspecting premises– Developing operational plan– Providing tools and equipment– Eliminating or mitigating hazards

(Continued)



• Toxic gases– Common and

dangerous threat during overhaul

– Wear appropriate PPE, including respiratory protection (Continued)



• Other hazards are present, such as fire-weakened floors

• Mark or barricade hazardous areas• Use gloves and eye protection

(Continued)



• Physical conditioning and correct lifting are necessary

• Fatigue is preventable cause of injury


Overhaul Tools and Equipment

• Pike poles and plaster hooks• Axes• Prying tools• Power saws, drills, and

screwdrivers

(Continued)


Overhaul Tools and Equipment

• Carryall, buckets, and tubs• Shovels, bale hooks, and pitchforks• Thermal imaging camera


Supervision of Overhaul

• By a supervisor/officer not directly engaged in overhaul tasks

• Fire investigator should be involved


Fire Safety During Overhaul

• Size of charged hoselines in overhaul may not be the same

• Disconnecting fire apparatus from hydrants

• Departmental SOPs may dictate one supply line left in place

(Continued)



• Attack lines used for overhaul are typically 1½ inch (38 mm) or 1¾ inch (45 mm)

• Water fire extinguishers or booster hoses may be used for small fires

• One attack line should be available

(Continued)



• Place nozzle so it will not cause additional damage

• Do not allow water damage from leaking hoselines

• Use a 100-foot (30 m) hoseline as the first section on attack lines


Overhaul Safety Considerations

• Maintain situational awareness• Work in teams of two or more• Maintain awareness of exit routes• Maintain a RIC

(Continued)


Overhaul Safety Considerations

• Monitor personnel for rehab• Beware of hidden gas or electrical

utilities• Continue using accountability

system


Locating Hidden Fires

• Before starting a search, evaluate the condition of the area

• Factors that affect condition of the building– Intensity of the fire– Amount of water used for control


Indicators of Loss of Structural Integrity

• Weakened floors• Concrete that has spalled• Weakened steel roof members• Walls offset• Weakened roof trusses• Mortar in wall joints opened

(Continued)


Indicators of Loss of Structural Integrity

• Wall ties holding veneer/curtain walls melted

• Heavy storage on mezzanines or upper floors

• Water pooled on upper floors• Large quantities of wet insulation


Detecting Hidden Fires

• Sight• Touch• Sound• Electronic sensors


Overhaul Procedures

• Begins in the area of most severe fire involvement

• Looking for fire extension should begin as soon as possible after fire is declared under control

• Systematically carried out

(Continued)


Overhaul Procedures

• If fire extended to other areas, path must be determined

• When floor beams are burned at ends or where they enter a party wall, flush the voids in the wall with water

(Continued)


Overhaul Procedures

• Check far side of the wall to see if fire or water has come through.

• Thoroughly check insulation materials


Understanding Basic Building Construction

• Assists firefighters in searching for hidden fires

• Windows or doors– Fire may remain within frames or

casings– Open these areas to ensure complete

extinguishment

(Continued)


Building Construction and Overhaul

• When fire has burned around combustible roof or cornice, open cornice and inspect for hidden fires

• Balloon construction — Check the attic and basement for fire extension

(Continued)



• Opening concealed spaces– Move the furnishings of the room to

locations where they will not be damaged

– Consider electrical wiring, gas piping, or plumbing

• Make neat, planned openings to ensure extinguishment and facilitate restoration

(Continued)



• Ceilings may be opened from below using a pike pole or other tool

• The plaster must first be broken on some ceilings

• When pulling a ceiling, do not stand directly under area to be opened (Continued)



• Always position body between area being pulled and doorway to keep exit route from being blocked

• Always wear full protective clothing, including eye and respiratory protection

(Continued)



• Small burning objects – Submerge entire objects in containers

of water– Bathtubs, sinks, lavatories, wash tubs

• Remove larger furnishings to the outside

(Continued)



• Scorched or partially burned articles may prove helpful to an investigator

• Use of wetting agents such as Class A foam is valuable – Cotton, upholstery, and baled goods– Must break bales of rags, cotton, hay

apart


Summary

• Customer service is the core of everything that fire departments do. Loss control is an important component of fire department service delivery and is but one aspect of customer-service opportunities.

(Continued)


Summary

• Salvage and overhaul operations are two of the most effective means of loss control.

• Planning, procedures, and equipment are essential for effective loss-control operations.
