Loose particulate
Preserve dry-removal and controlled-capture options before introducing methods that can redistribute or smear residue.
Fire & Smoke Diagnostic + Material Intelligence
Do not ask only “is there soot?” Ask what residue is present, where it traveled, what it is on, and whether the result is verified.
The same smoke event can create dry particulate, oily films, baked deposits, odor reservoirs, suppression-water damage and system contamination at the same property. SDM Intelligence organizes those conditions into separate decision paths.
Residue classification engine
Classify behavior before choosing a broad cleaning method.
Greasy / oily
Use test areas because oily films can transfer, smear and respond differently from loose carbon-like particulate.
Baked-on
Separate removable contamination from heat-altered substrate or finish before deciding that additional cleaning will solve the condition.
Protein-like
Strong odor may exist with limited visible residue, making source location and surface cleaning especially important.
Multiple residues
Different rooms and materials can require different classifications. One fire does not guarantee one residue type.
Controlled test area
Record whether residue releases, smears, stains, or reveals substrate damage before scaling a method across retained materials.
Material response matrix
The substrate changes the decision.
| Material group | Primary observations | Decision direction | Escalation / verification |
|---|---|---|---|
| Painted walls & ceilings | Residue load, finish, staining, heat effect, test response | Test cleanability before later coating or replacement decisions | Verify residue/odor; do not coat an unresolved source |
| Wood & cabinetry | Finish, heat line, charring, porosity, penetration | Clean/test, specialty restoration, refinishing, or removal evaluation | Structural questions stay with qualified professionals |
| Insulation / cavities | Residue, odor, suppression water, access limitations | Investigate as a concealed reservoir rather than assuming surface cleaning reaches it | Verify moisture and odor pathways before closure |
| Metal / laminate / plastic | Corrosion, yellowing, staining, heat deformation | Prioritize documentation and compatible cleaning tests | Escalate specialty/heat-damage questions as needed |
| Flooring / carpet / textiles | Tracked residue, fiber/dye sensitivity, odor, heat | Protect traffic paths and use material-specific cleaning/specialty processing | Re-check after surrounding work is complete |
| Electronics / high-value contents | Heat, soot, moisture, energizing status, value/sensitivity | Segregate and route to qualified specialty evaluation | Do not use generic cleaning or energizing assumptions |
Smoke migration map
Build the pathway map from the source outward.
1
Source
Room or area of origin, char, debris and strongest residue/odor.
2
Openings
Doors, windows, envelope damage and connected rooms.
3
Vertical paths
Stairs, shafts, pipe runs, chases, wall and ceiling cavities.
4
HVAC
Operating history, returns, supplies, filters, blower and observed residue/odor.
5
Remote verification
Compare residue and odor intensity in distant or cleaned areas after normal cycles.
Restore / specialty / remove / seal
Make the decision in sequence.
Control the source and debris.
Do not start with fragrance, coatings or broad air treatment while a continuing source or contaminated debris remains unresolved.
Test the retained material.
Classify residue behavior and substrate response in a controlled area before scaling the method.
Restore when the material responds appropriately.
Use material-specific cleaning and contamination-control procedures while protecting completed areas.
Use specialty handling when the material or value demands it.
Electronics, art, high-value items, specialty textiles and regulated systems may require specialized providers.
Evaluate removal when material condition or contamination cannot be acceptably resolved.
Removal decisions should distinguish restoration practicality from structural or regulated conclusions.
Consider sealing later, not first.
Suitable retained substrates may be candidates after source control, cleaning and deodorization are resolved; sealing should not hide an unresolved source.
Verify.
Re-check visible residue, odor, HVAC-cycle response, cleaned-zone recontamination and concealed-pathway uncertainty before reconstruction or turnover.
Mixed-hazard bridge
A fire incident can open a water incident automatically.
Suppression water is not a footnote. Sprinkler discharge and hose streams can create separate moisture conditions in ceilings, insulation, flooring, wall cavities and lower levels. The diagnostic engine treats that as a parallel assessment path instead of burying it inside the smoke report.
Professional boundary
Diagnostic organization is not a licensed conclusion.
SDM Intelligence can organize observations and explain restoration decision paths. Structural capacity, electrical safety, gas systems, code compliance, licensed HVAC work and other regulated questions remain with the appropriate qualified professional or authority.
Verification & outcomes
Do not stop at apparent improvement.
Use a separate verification stage to check for persistent residue, odor reservoirs, HVAC-cycle recurrence, recontamination, secondary water and unresolved concealed pathways before reconstruction or turnover.
