  3. PURPOSE OF SALVAGE TS 16–2 To reduce damage from fire, smoke, water, heat, cold, or weather during and after a fire

  4. PURPOSES OF OVERHAUL TS 16–3 • To search out and extinguish hidden fires • To protect the scene after the fire • To preserve evidence of the fire’s origin and cause • To restore premises to safe condition

  5. SALVAGE PLANNING TS 16–4 • Salvage SOPs • Special preplans for buildings with high-value contents • Awareness of contents vital to businesses in commercial occupancies • Working with loss control representatives of local businesses

  6. SALVAGE PROCEDURES TS 16–5 • When to begin salvage operations • Coordinating salvage with fire attack • How to arrange and protect building contents • Commercial occupancy challenges • Removing large quantities of water

  7. HOW TO ARRANGE & PROTECT BUILDING CONTENTS TS 16–6 • Gathering in close piles in center of room • Placing high objects at ends of piles and using rolled rugs as ridgepoles • Placing small objects (pictures, curtains, lamps) on larger objects such as couches or beds • Using water-resistant materials to raise furniture off wet floors

  8. COMMERCIAL OCCUPANCY CHALLENGES TS 16–7 Ceiling-to-floor Display Shelves Contents Stacked too Close to Ceiling Unpalleted Storage High-piled Stock

  9. TYPICAL SALVAGE EQUIPMENT TS 16–11 • Automatic sprinkler kit • Carryall • Floor runner • Dewatering device • Water vacuum • Squeegee • Mop and wringer bucket

  10. CONSTRUCTION METHODS FOR REMOVING & ROUTING WATER TS 16–13 Water Chute Spliced Chutes Catchall

  11. GUIDELINES FOR COVERING OPENINGS TS 16–14 • Cover all exterior openings. • Cover broken or missing doors or windows with plywood, heavy plastic, or similar materials. • Cover openings in roofs with plywood, roofing paper, heavy plastic sheeting, or tar paper. • Tack down edges of tar paper or plastic with lath and roofing nails.

  12. DEFINITION OF OVERHAUL TS 16–15 The practice of searching a fire scene to detect hidden fires or sparks that may rekindle and to identify the possible point of origin and cause of fire

OVERHAUL SAFETY GUIDELINES & PROCEDURES TS 16–17a • Make sure that your very first overhaul step is determining the condition of the building. • Wear proper protective clothing, including positive-pressure SCBA. • Wear eye protection when it is safe to remove breathing apparatus. • Use 1½-inch (38 mm) or 1¾-inch (45 mm) charged attack lines for extinguishing hidden fires.

  15. OVERHAUL SAFETY GUIDELINES & PROCEDURES (cont.) TS 16–17b • Extinguish small hidden fires during minor overhaul operations with air-pressurized water extinguishers or booster lines, backed up by at least one attack line. • Avoid additional water damage.

  16. AVOIDING ADDITIONAL WATER DAMAGE TS 16–18 • Place nozzle in such a way that if it is accidentally opened it will cause no additional water damage. • Tighten or repair leaking couplings. • Use a 100-foot (30 m) length of hose as the first section on attack lines.

  17. PRIMARY FACTORS AFFECTING BUILDING CONDITION TS 16–19 Fire Intensity Amount of Water Used

  18. SIGNS OF DANGEROUS BUILDING CONDITIONS TS 16–20 • Weakened floors due to floor joists being burned away • Concrete that has spalled due to heat • Weakened steel roof members • Walls offset because of elongation of steel roof supports • Weakened roof trusses due to burn-through of key members • Mortar in wall joints opened because of excessive heat • Wall ties holding veneer walls melted from heat

  19. INDICATORS OF HIDDEN FIRES TS 16–21 • Sight • Discoloration of materials • Peeling paint • Smoke emissions from cracks • Cracked plaster • Rippled wallpaper • Burned areas • Touch — Feel walls and floors for heat with the back of the hand • Sound • Popping or cracking of fire burning • Hissing of steam

  20. CHECKING FOR & EXTINGUISHING FIRE EXTENSION TS 16–22a • If floor beams are burned at their ends where they enter a party wall— • Flush with water. • Check far side of wall and extinguish as necessary. • Remove, check, and extinguish insulation materials. • If fire has burned around doors and windows, open door and window casings and extinguish fires.

  21. CHECKING FOR & EXTINGUISHING FIRE EXTENSION (cont.) TS 16–22b • If fire has burned around a combustible roof or cornice, open the cornice and inspect for hidden fires. • If sensory or electronic sensor indicates, remove materials and extinguish hidden fires in concealed spaces below floors, above ceilings, or within walls.

  22. REMOVING DEBRIS & WATER TS 16–23 • Use carryalls (debris bags) to remove debris. • To catch falling debris • To provide a water basin for immersing small burning objects • Use water vacuums, scoops, shovels, mop wringers and buckets, submersible pumps to remove water.

  23. FIREFIGHTER’S RESPONSIBILITY IN PROTECTING EVIDENCE TS 16–24 • The fire chief has the legal responsibility within most jurisdictions for determining the cause of a fire. • Questions first-arriving firefighters should ask: • Are room contents as they normally would be?
