Fire & Smoke Odor Removal in Xactimate (CLN ODOR / CLNDODR): Soot Sponge Test & Hydroxyl Generator Photo Proof
Xactimate Codes: CLN ODOR, CLN DODR, CLN SFS | Standard: ANSI/IICRC S700 & RIA Fire Restoration Guidelines | Protected: +$2,790 per smoke/fire claim
Technical Answer Summary (ANSI/IICRC S700 & RIA Fire Restoration Guidelines)
Following a kitchen protein fire, electrical fire, or furnace puffback, microscopic soot and volatile organic compounds (VOCs) migrate through HVAC ductwork and convective pressure into rooms far from visible charring. Insurance adjusters routinely deny Xactimate smoke remediation line items—such as CLN SFS (Clean Wall/Ceiling — Heavy Soot), CLN ODOR (Hydroxyl / Ozone Generator per day), and CLN DODR (Deodorize Building — Thermal Fogging per CF)—in adjacent bedrooms and hallways by claiming "no visible smoke damage." Performing and photographing a single-stroke Dry Chemical Vulcanized Rubber Sponge test (plus white methanol/alcohol wipe for invisible yellow protein grease) across door tops, ceiling returns, and closet interiors proves particulate deposition and unlocks full-structure cleaning and cubic-foot deodorization.
Adjuster Denial Trap: Adjusters denying smoke cleaning (CLN SFS), hydroxyl generator days (CLN ODOR), and thermal deodorization (CLN DODR) in rooms away from the fire origin unless dry chemical sponge wipe streaks prove protein or synthetic soot migration.
3-Column Xactimate Denial Trigger vs. Field Photo Evidence Matrix
| Adjuster Denial Reason / Scrub Trigger | Required Field Photo & Meter Evidence (IICRC Standard) | Copy-Paste Xactimate F9 Note Justification |
|---|---|---|
| Adjuster denies CLN SFS (wall/ceiling cleaning) in bedrooms claiming "smoke stayed in the kitchen" | Close-up photo of vulcanized dry chemical soot sponge showing dark gray/black carbon transfer streak on upper wall and ceiling return register | Convective heat and HVAC recirculation deposited fine carbon soot particulates throughout second-floor bedrooms. Attached IICRC S700 dry chemical sponge test photos on bedroom ceiling and door casing verify heavy particulate deposition requiring CLN SFS. |
| Carrier cuts Hydroxyl Generator runtime (CLN ODOR) or denies Thermal Fogging cubic footage (CLN DODR) | Photo of commercial 3-optic Hydroxyl Generator serial plate + room laser dimensions proving total conditioned cubic volume (L x W x H) | Per ANSI/IICRC S700 odor counteraction principles, hydroxyl radical oxidation (CLN ODOR) was operated during occupied structure cleaning, followed by solvent-based thermal fogging (CLN DODR) sized to match thermal expansion particle physics across 18,400 CF. |
| Reviewer rejects shellac/odor-blocking primer coat (PNT B2 / PNT SP) before repainting | Photo of pigmented shellac stain/odor sealer (e.g., BIN / Kilz Restoration) bucket + wet-film application over cleaned drywall | Standard latex primer does not encapsulate lipid/protein smoke molecules embedded in gypsum paper. Pigmented shellac vapor-barrier sealer (PNT SP) is mandatory after CLN SFS to prevent bleed-through and heat-activated odor return. |
Copy-Paste Xactimate F9 Note Justification
F9 NOTE (CLN SFS / CLN ODOR / CLN DODR): Fire and smoke particulate assessment performed per ANSI/IICRC S700 guidelines. Dry chemical vulcanized rubber sponge testing and alcohol protein-film wipes (timestamped VouchCam photos attached by room) confirmed pressurized soot and VOC migration beyond the room of origin into adjacent living spaces and HVAC pathways. Hydroxyl radical generators (CLN ODOR) and thermal deodorization (CLN DODR) were deployed across the verified cubic footage prior to shellac vapor encapsulation.
Mandatory On-Site Field Photo Checklist
- Hard Gate #1: Clean vulcanized dry soot sponge BEFORE swipe vs. darkened sponge AFTER single 12-inch swipe on ceiling/trim
- Hard Gate #2: HVAC return and supply register grilles showing soot impingement rings
- Hard Gate #3: Hydroxyl or Ozone generator deployed in room with serial plate and hour-meter visible (CLN ODOR)
- Hard Gate #4: Pigmented shellac odor-encapsulating primer application prior to finish paint
Frequently Asked Questions
How do you prove invisible protein fire smoke from a kitchen stove fire in Xactimate?
Protein fires leave a translucent, yellowish, foul-smelling dehydrate grease film that often barely shows on a dry sponge. Wiping a clean white cloth dampened with isopropyl alcohol or degreaser across the top edge of a door or cabinet reveals a yellow-brown residue that photographs clearly for adjusters.
When should you use a Hydroxyl Generator vs. an Ozone Generator for Xactimate CLN ODOR?
Hydroxyl generators are safe to operate while technicians or occupants are inside the structure and will not degrade rubber, elastic, or natural fabrics. Ozone generators require an unoccupied, sealed warning zone because high-concentration ozone oxidizes rubber and irritates lungs.
