Fire Damage Testing for Insurance Claims in Oregon

Fire- and smoke-damage insurance claims frequently involve questions about the extent of contamination, areas requiring cleaning, ventilation-system involvement, affected contents, and the adequacy of completed remediation.

5 Microns Inc. provides independent fire-damage testing for insurance claims throughout Oregon. Our assessments may help document soot, char, ash, smoke-related surface residue, selected combustion byproducts, HVAC conditions, and post-remediation findings.

Services are available for residential, commercial, multifamily, agricultural, and industrial properties affected by structure fires, neighboring-unit fires, wildfires, heating-system incidents, electrical fires, vehicle fires, and other combustion events.

Independent Fire-Damage Documentation

5 Microns Inc. is an independent environmental testing and consulting company. We do not provide fire restoration, smoke cleaning, demolition, reconstruction, public-adjusting services, or fire-origin-and-cause investigations.

Our role may include:

• Reviewing available incident information
• Reviewing relevant claim and remediation documents
• Assessing accessible property conditions
• Identifying potential smoke and residue pathways
• Developing a representative sampling strategy
• Collecting surface or material samples
• Coordinating laboratory analysis
• Interpreting the findings
• Providing written documentation

Because 5 Microns Inc. does not profit from cleaning, demolition, or reconstruction, our findings are independent of the amount of corrective work that may be recommended.

How Testing May Assist an Insurance Claim

Fire-damage testing may help document conditions relevant to questions such as:

• Did smoke-related residue reach rooms outside the direct fire area?
• Are suspicious particles consistent with soot, char, or ash?
• Did smoke potentially migrate into an adjoining unit?
• Could the HVAC system have collected or distributed particles?
• Is visible residue present on selected contents or equipment?
• What conditions were documented before cleaning?
• What conditions remain after remediation?
• Is there evidence of possible cross-contamination?
• Would additional investigation help clarify disputed areas?

Testing does not determine whether damage is covered under an insurance policy. Coverage, liability, claim value, and policy interpretation remain the responsibility of the insurer, insured, attorneys, and other appropriate parties.

When Insurance-Related Fire Testing May Be Appropriate

Independent testing may be considered when:

• The extent of smoke contamination is disputed
• The insurer and property owner disagree about affected areas
• A restoration contractor’s scope does not include all areas of concern
• Smoke traveled beyond the visibly burned portion of the property
• A neighboring-unit fire may have affected another residence or business
• Wildfire smoke or ash entered a building
• HVAC contamination is questioned
• Contents or inventory may have been exposed
• Cleaning began before the property was fully documented
• Residue remains after remediation
• An independent post-remediation assessment is requested
• A supplemental claim requires additional documentation
• An attorney needs technical information concerning sampled conditions

The appropriate testing scope depends on the property, incident, existing documentation, and questions requiring evaluation.

Testing Before Cleanup Begins

When conditions allow, assessment and testing should be considered before extensive cleaning, demolition, or disposal begins.

Pre-remediation documentation may help establish:

• The location and appearance of visible residue
• The apparent distribution of soot or ash
• Conditions outside the direct fire area
• Potential smoke-migration pathways
• Possible HVAC involvement
• Affected categories of contents
• Comparison locations
• A baseline for later assessment

Emergency work necessary to protect occupants, prevent additional damage, or stabilize the property should not be delayed solely for testing.

When immediate work is necessary, property owners should retain available photographs, videos, inventories, contractor records, filter changes, cleaning logs, and information about materials removed or discarded.

Testing After Cleanup Has Already Started

Testing can still be performed after cleaning or demolition begins, but earlier work may alter the evidence available for evaluation.

Cleaning may:

• Remove visible residue
• Reduce particle concentrations
• Move residue to another area
• Alter comparison locations
• Change HVAC conditions
• Eliminate materials that could have been sampled
• Make reconstruction of original conditions more difficult

The assessment should document known cleaning activities and explain how they may limit interpretation.

Fire-Related Surface Testing

Surface testing may help evaluate settled residue following a fire or smoke event.

Potential sampling locations include:

• Walls and ceilings
• Floors and baseboards
• Window sills
• Door frames
• Countertops
• Shelving
• Furniture
• Ventilation registers
• Accessible HVAC components
• Equipment
• Commercial inventory
• Exterior surfaces
• Areas reportedly cleaned
• Comparison locations

The method selected depends on whether the investigation concerns particle identification, chemical analysis, metals, post-remediation verification, or another objective.

Tape-Lift Sampling for Insurance Documentation

Tape-lift sampling may be used to collect particles from selected surfaces for microscopic examination.

Laboratory-supported examination may help identify particles with characteristics consistent with:

• Soot
• Char
• Ash
• Fibers
• Soil
• Dust
• Other particulate debris

Tape-lift findings may help document whether combustion-related particles were identified in selected locations.

A tape-lift sample represents the specific surface sampled. One sample cannot automatically characterize an entire room, building, ventilation system, or category of contents.

Surface-Wipe Testing

Surface-wipe sampling may be used when a measured area needs to be evaluated for selected compounds or elements.

Depending on the incident, wipe samples may be analyzed for:

• Polycyclic aromatic hydrocarbons
• Selected metals
• Incident-specific combustion byproducts
• Comparison between cleaned and uncleaned surfaces

Wipe results may provide numerical laboratory data for a defined surface area. Interpretation should account for surface type, sampled area, cleaning history, background sources, and available comparison information.

PAH Testing for Fire Claims

Polycyclic aromatic hydrocarbons, commonly called PAHs, may be produced during incomplete combustion.

PAH testing may be considered when:

• Petroleum-based products burned
• Plastics, fuels, furnishings, or mixed contents were involved
• Significant surface deposition is suspected
• Compound-specific documentation is needed
• Commercial or industrial materials burned
• Post-remediation conditions are disputed

PAHs also have sources unrelated to a particular fire. A detected compound does not automatically establish that it originated from the reported incident.

Results should be interpreted alongside the fire history, sample location, surface type, cleanup history, and comparison findings.

Metals Testing for Fire and Wildfire Claims

Fire residue and wildfire ash may contain metals originating from natural and manufactured materials.

Potential sources include:

• Soil and vegetation
• Paints and coatings
• Roofing and siding
• Treated wood
• Vehicles
• Electronics
• Batteries
• Machinery
• Plumbing components
• Stored household products
• Commercial or agricultural materials

Metals testing may be appropriate when the materials involved in the fire support that analysis.

The analytical panel should be selected according to the suspected sources. The same metals should not automatically be tested during every fire-damage claim.

HVAC Testing for Insurance Claims

Heating and ventilation systems may collect or transport combustion particles.

An HVAC-related assessment may consider:

• Whether the system operated during or after the fire
• Whether outdoor air was introduced
• Supply and return registers
• Filters and filter housings
• Air handlers
• Blower compartments
• Accessible duct surfaces
• Mechanical rooms
• Shared ventilation zones
• Cleaning and filter-replacement records

Testing one accessible register or component does not automatically characterize the entire HVAC system. The system configuration, operating history, observations, and sample results should be evaluated together.

Smoke Migration Between Rooms or Units

Smoke can move beyond the area where flames occurred through:

• Doorways
• Hallways
• Stairwells
• Wall and ceiling openings
• Plumbing penetrations
• Electrical penetrations
• Shared ventilation systems
• Elevator shafts
• Exterior windows and balconies
• Pressure differences between spaces

This is particularly relevant in apartments, condominiums, hotels, offices, and other multitenant properties.

Testing may help document conditions in adjoining units, common areas, ventilation zones, or locations described as unaffected.

Wildfire Smoke and Ash Claims

An Oregon property does not need to burn to experience wildfire smoke or ash exposure.

Smoke and ash may enter through:

• Open windows and doors
• Outdoor-air intakes
• Mechanical ventilation
• Gaps around windows or doors
• Roof and wall penetrations
• Attached garages
• Routine entry and exit
• Equipment or belongings brought indoors

Testing may help evaluate selected interior surfaces, accessible HVAC components, exterior ash, or surrounding soil.

Wildfire samples may contain mixtures of combustion residue, soil, pollen, fibers, and ordinary dust. Results should be interpreted within the context of the wildfire event and property conditions.

Claims Involving Contents and Personal Property

Smoke and ash may settle on:

• Furniture
• Clothing and textiles
• Electronics
• Books and documents
• Artwork
• Appliances
• Children’s items
• Stored household property
• Machinery
• Commercial inventory

Representative sampling may help document conditions on selected items or categories of contents. However, a limited number of samples cannot characterize every object within the property.

Testing does not automatically establish whether an item should be cleaned, restored, discarded, or replaced. Those decisions may also involve the material, intended use, restoration options, cost, and policy terms.

Commercial and Industrial Insurance Claims

Commercial fire claims may involve:

• Multiple tenant spaces
• Warehouses
• Manufacturing facilities
• Offices
• Retail properties
• Restaurants
• Hotels
• Agricultural buildings
• Equipment and machinery
• Raw materials
• Finished inventory
• Employee workspaces
• Multiple ventilation zones

The sampling plan should reflect the property’s layout, operations, fire history, remediation activities, and the decisions that will rely on the findings.

Representative samples can address defined questions, but one result should not automatically be applied to an entire facility or all inventory.

Post-Remediation Testing for Insurance Claims

After fire- or smoke-damage remediation, an independent assessment may help document accessible conditions in the treated areas.

The evaluation may include:

• Review of the reported remediation scope
• Visual observations
• Surface sampling
• Comparison sampling
• HVAC assessment
• Evaluation of possible cross-contamination
• Laboratory analysis relevant to the original incident

Post-remediation testing does not guarantee that every inaccessible or concealed surface is free of residue. It documents the areas evaluated and samples collected at the time of the assessment.

Whenever practical, testing expectations should be discussed before remediation begins.

Disputed Remediation Boundaries

Insurance disputes may arise when one party considers a room or area affected and another considers it outside the fire-damage zone.

A sampling strategy may compare:

• Rooms near and far from the fire
• Areas separated by closed doors
• Different floors
• Adjoining units
• Separate HVAC zones
• Cleaned and uncleaned surfaces
• Interior and exterior locations
• Reportedly affected and unaffected areas

Comparison sampling may provide context, but comparison areas must be selected carefully. They may contain background dust, historical combustion particles, or unrelated residue.

Evidence Preservation and Documentation

Fire-damage conditions can change quickly as cleanup, demolition, weather, ventilation, and normal occupancy continue.

Useful records may include:

• Photographs and videos
• Fire-department reports
• Restoration scopes
• Estimates and invoices
• Cleaning logs
• Demolition records
• HVAC service records
• Filter-replacement information
• Contents inventories
• Previous testing reports
• Laboratory reports
• Correspondence identifying disputed areas

Property owners should avoid intentionally disturbing suspected residue solely to create evidence. Appropriate sampling and documentation should be performed under a defined investigation plan.

Sample Identification and Records

A fire-damage report should clearly identify:

• Sample numbers
• Collection dates
• Sampling methods
• Sampling locations
• Surface types
• Requested laboratory analyses
• Relevant observations
• Photographic documentation when included
• Laboratory results
• Interpretation limitations

Accurate location records are important because analytical results have limited value when the sampling area cannot be reliably identified.

Chain-of-Custody Documentation

Samples submitted to a laboratory are typically accompanied by chain-of-custody documentation.

This record may identify:

• Client or project
• Sample numbers
• Collection date
• Requested analyses
• Sample collector
• Transfer or shipment information
• Laboratory receipt

Chain-of-custody documentation supports sample identification and handling. It does not, by itself, establish the source or significance of the material collected.

Understanding Laboratory Results

A laboratory report provides information about the submitted samples and requested analyses.

Results should not be interpreted in isolation. Appropriate interpretation may require consideration of:

• Incident history
• Materials involved
• Sampling method
• Sample location
• Surface type
• Cleaning history
• Background sources
• Comparison samples
• Building layout
• HVAC operation
• Investigation limitations

A detected particle or compound does not automatically prove widespread contamination. Similarly, a non-detect or negative finding from one sample does not establish that all unsampled areas are unaffected.

What Our Report May Include

Depending on the assignment, a written report may include:

• Project background
• Information provided by the client
• Scope of services
• Property areas assessed
• Observed conditions
• Sampling methods
• Sample-location descriptions
• Photographs
• Laboratory reports
• Discussion of findings
• Professional interpretations
• Limitations
• Recommendations for additional evaluation when warranted

The report should distinguish observed facts, laboratory results, client-provided information, and professional interpretations.

What Fire-Damage Testing Cannot Decide

Environmental testing does not determine:

• Whether an insurance policy provides coverage
• The amount an insurer must pay
• Legal liability
• Claim value
• Whether a particular exclusion applies
• The fire’s origin and cause
• Whether fraud occurred
• The legal admissibility of every finding
• Whether every item should be replaced
• Whether an insurer must approve a particular remediation scope

Those determinations belong to the appropriate insurance, legal, fire-investigation, or other qualified professionals.

Working With Property Owners, Adjusters, and Attorneys

Testing may be requested by:

• Property owners
• Tenants
• Property managers
• Insurance carriers
• Adjusters
• Public adjusters
• Attorneys
• Restoration contractors
• Commercial property representatives

The investigation scope, client, authorized recipients, property access, payment responsibility, and intended use of the report should be identified before work begins.

Frequently Asked Questions

Can fire-damage testing support an insurance claim?

Yes. Testing can provide independent documentation of observed conditions, sampling locations, and laboratory findings. It does not determine whether the claim is covered or how much the insurer must pay.

Should I obtain testing before the property is cleaned?

When practical, pre-remediation testing can help document the original distribution of residue. Emergency stabilization and necessary safety measures should not be delayed solely for testing.

Can you test after cleaning has already started?

Yes. However, cleaning or demolition may alter evidence and limit conclusions about the conditions that existed beforehand.

Can testing show that smoke reached another room?

Representative surface sampling, observations, building information, and ventilation history may help evaluate whether combustion residue is present in areas beyond the direct fire zone.

Can you test an apartment affected by a neighboring-unit fire?

Yes. Selected surfaces and accessible ventilation components may be evaluated when smoke may have migrated from another unit.

Can you test an HVAC system for a fire claim?

Accessible HVAC components may be assessed when the system could have collected or transported combustion particles.

Do you work for insurance companies or property owners?

5 Microns Inc. may be retained by property owners, insurers, attorneys, property managers, contractors, or other authorized parties. Our findings remain independent regardless of who retains us.

Do you negotiate with the insurance company?

No. We provide environmental assessment and documentation. We do not act as a public adjuster or determine insurance coverage.

Do you determine the cause of the fire?

No. Fire-origin-and-cause investigations should be performed by appropriately qualified fire investigators.

Can you perform post-remediation testing?

Yes. We can evaluate selected accessible areas after cleaning and document the conditions present at the time of the assessment.

Does one sample prove that an entire building is contaminated?

No. A sample represents its particular collection location. Multiple samples and comparison areas may be necessary to evaluate a larger property.

Will the insurance company accept the report?

Acceptance is determined by the insurance carrier and other involved parties. The report provides independent observations, sampling information, laboratory results, interpretations, and limitations.
