Commercial Fire and Smoke Damage Testing in Oregon

A fire or smoke event can affect far more than the visibly burned portion of a commercial property. Soot, char, ash, and other combustion-related residues may spread through ventilation systems, open production areas, adjoining tenant spaces, warehouses, offices, equipment rooms, and inventory-storage areas.

5 Microns Inc. provides independent commercial fire and smoke damage testing throughout Oregon. Our assessments can help property owners, business operators, facility managers, contractors, insurers, adjusters, and attorneys document suspected fire- and smoke-related contamination.

Testing may be appropriate after a structure fire, neighboring-property fire, wildfire, electrical incident, equipment malfunction, vehicle fire, heating-system problem, or another event involving combustion residue.

Independent Commercial Fire-Damage Assessment

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

Our role may include:

• Reviewing information about the fire or smoke event
• Reviewing available restoration and claim documents
• Assessing accessible commercial areas
• Evaluating potential smoke-migration pathways
• Developing a representative sampling strategy
• Collecting surface or material samples
• Assessing accessible HVAC components
• Coordinating laboratory analysis
• Interpreting the findings
• Providing written documentation

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

Commercial Properties We Can Evaluate

Commercial fire- and smoke-damage testing may be appropriate for:

• Office buildings
• Retail stores
• Shopping centers
• Restaurants
• Hotels
• Apartment complexes
• Warehouses
• Distribution facilities
• Manufacturing properties
• Agricultural facilities
• Healthcare offices
• Institutional buildings
• Schools
• Mixed-use properties
• Vehicle-maintenance facilities
• Storage facilities
• Equipment yards
• Multitenant commercial buildings

The assessment should be tailored to the property’s layout, operations, ventilation, inventory, equipment, and intended use.

Why Commercial Fire Investigations Can Be Complex

Commercial properties may contain multiple operational areas, tenant spaces, mechanical systems, stored materials, and categories of inventory.

Factors affecting the investigation may include:

• Size and configuration of the building
• Location of the original fire
• Materials that burned
• Fire-suppression activities
• Shared or separate ventilation zones
• Open warehouse or production areas
• Movement of employees and contractors
• Equipment and machinery
• Stored products
• Sensitive operations
• Cleanup completed before the assessment
• Areas that remained occupied
• Multiple parties participating in the claim

A limited residential-style sampling approach may not adequately address a large or complex commercial loss.

A Business Does Not Need to Burn to Be Affected

A commercial property may experience smoke or ash contamination even when flames never entered the building.

Possible scenarios include:

• A fire in an adjoining tenant space
• A fire in a neighboring building
• Smoke entering through outdoor-air intakes
• Wildfire smoke entering the property
• A loading-dock or vehicle fire
• An equipment fire inside a limited area
• Smoke traveling through a shared corridor
• A kitchen or restaurant fire affecting another unit
• An electrical incident inside a mechanical room
• Smoke migrating between floors

Combustion particles can settle on surfaces after the visible smoke has cleared. Consequently, an assessment may need to include locations outside the direct fire area.

What Commercial Fire and Smoke Testing Can Evaluate

Depending on the incident, testing may help evaluate:

• Soot, char, and ash particles
• Smoke-related surface residue
• Residue distribution between operational areas
• Potential HVAC-system involvement
• Adjoining tenant spaces
• Equipment and machinery
• Commercial inventory
• Warehouses and storage areas
• Selected metals
• Polycyclic aromatic hydrocarbons
• Wildfire ash
• Conditions before cleanup
• Conditions after remediation
• Possible cross-contamination
• Outdoor work and storage areas

Not every commercial investigation requires every type of testing. The analytical scope should reflect the materials involved and the questions that need to be answered.

Developing a Commercial Sampling Strategy

A commercial sampling plan may divide the property into functional or investigative zones.

Potential zones may include:

• Direct fire area
• Adjacent operational area
• Offices
• Warehouse space
• Production floor
• Equipment rooms
• Mechanical rooms
• Separate tenant spaces
• Loading and receiving areas
• Inventory-storage locations
• Employee break areas
• Areas reportedly unaffected
• Exterior ash-deposition areas

Samples should be selected to answer defined questions. Random sampling without a clear purpose may produce results that are difficult to interpret or apply.

Tape-Lift Sampling for Commercial Properties

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

Potential sampling locations include:

• Shelving
• Equipment housings
• Work surfaces
• Walls and ceilings
• Window ledges
• Ventilation registers
• Storage racks
• Office furniture
• Inventory packaging
• Mechanical components
• Areas reportedly cleaned
• Comparison locations

Microscopic examination may help identify particles with characteristics consistent with:

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

Each sample represents the specific surface collected. One tape lift cannot automatically characterize an entire warehouse, production area, or ventilation system.

Surface-Wipe Testing

Surface-wipe sampling may be used when a defined 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
• Residue on equipment or work areas

The analytical method should be selected according to the materials believed to have burned and the intended use of the results.

Soot, Char, and Ash Testing

Commercial fires may involve a complex mixture of materials, producing several forms of combustion residue.

Soot generally consists of fine particles associated with incomplete combustion. Char is partially burned material, while ash contains the mineral-rich residue remaining after combustion.

Commercial samples may also contain:

• Ordinary dust
• Fibers
• Soil
• Product debris
• Packaging material
• Manufacturing residue
• Building-material fragments
• Particles unrelated to the fire

Laboratory-supported analysis can help evaluate whether collected particles exhibit characteristics consistent with combustion residue. Findings should be interpreted alongside the incident history, operations, building layout, cleaning activities, and distribution of results.

PAH Testing After a Commercial Fire

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

PAH testing may be considered when:

• Petroleum products burned
• Fuels or lubricants were involved
• Plastics or mixed inventory burned
• Vehicles or machinery were affected
• Significant surface deposition is suspected
• Compound-specific documentation is needed
• Post-remediation conditions are being evaluated

PAHs may also originate from sources unrelated to the reported fire. Results should be interpreted in relation to the sample location, surface type, facility operations, background sources, and cleanup history.

Metals Testing After Commercial and Industrial Fires

Commercial fire residue may contain metals originating from:

• Machinery
• Electronics
• Batteries
• Vehicles
• Paints and coatings
• Roofing and siding
• Plumbing components
• Treated wood
• Raw materials
• Stored products
• Soil and vegetation
• Utility infrastructure

Metals analysis may be appropriate when the incident information supports testing for particular elements.

The analytical panel should be selected according to the known or suspected materials involved. The same metals should not automatically be tested following every commercial fire.

HVAC and Mechanical-System Assessment

Commercial ventilation systems may transport smoke particles between rooms, floors, tenant spaces, and operational zones.

An HVAC-related assessment may consider:

• Whether the system operated during or after the fire
• Outdoor-air intake locations
• Shared and separate ventilation zones
• Supply and return registers
• Filters and filter housings
• Air handlers
• Blower compartments
• Accessible duct surfaces
• Mechanical rooms
• Filter-replacement and cleaning records

A sample from one register or air handler does not automatically characterize the entire system. Larger properties may contain multiple systems requiring separate consideration.

Equipment and Machinery

Smoke particles may settle on equipment housings, controls, exposed components, tools, production lines, and machinery.

An equipment-related assessment may consider:

• Proximity to the fire
• Whether the equipment was operating
• Surface materials
• Cooling fans and air intakes
• Enclosures
• Cleaning performed
• Sensitivity of the equipment
• Intended future use
• Whether representative sampling is appropriate

Environmental surface testing does not replace a mechanical, electrical, engineering, or manufacturer-specific evaluation when those services are required.

Commercial Inventory and Stored Products

Smoke and ash may settle on inventory, packaging, raw materials, finished products, and storage containers.

Representative testing may help document selected categories of inventory, but a limited number of samples cannot characterize every item in a commercial facility.

The sampling plan may consider:

• Product type
• Packaging
• Storage location
• Proximity to the fire
• Air movement
• Whether containers were open or sealed
• Surface characteristics
• Cleaning or handling after the event
• Intended use of the products

Testing does not automatically determine whether inventory should be cleaned, released, discarded, or replaced.

Warehouses and Distribution Facilities

Warehouse investigations may involve large open areas, high shelving, multiple loading points, and substantial inventories.

Potential considerations include:

• Smoke stratification
• Ceiling and upper-surface deposits
• Ventilation patterns
• Loading-bay doors
• Storage-rack locations
• Product packaging
• Forklift and vehicle movement
• Cleaning routes
• Areas isolated from the primary smoke pathway

A zoned assessment may provide more useful information than treating the entire warehouse as one uniform space.

Restaurants and Food-Service Properties

Commercial cooking facilities may experience fires involving grease, cooking oils, appliances, ventilation hoods, electrical equipment, furnishings, and stored products.

A restaurant assessment may consider:

• Kitchen and dining areas
• Exhaust hoods
• Adjacent tenant spaces
• HVAC components
• Food-storage areas
• Equipment surfaces
• Seating and furnishings
• Areas cleaned before testing

Environmental fire-residue testing does not replace inspections required by health, fire, building, or food-safety authorities.

Hotels and Multifamily Properties

Hotels, apartment complexes, and other large residential-commercial properties may contain numerous units connected by common areas and shared systems.

Smoke may move through:

• Hallways
• Stairwells
• Elevator shafts
• Door openings
• Wall and ceiling penetrations
• Plumbing and electrical pathways
• Shared ventilation
• Exterior windows and balconies

Testing may be developed for the original fire area, adjoining units, common areas, HVAC zones, or locations described as unaffected.

Agricultural and Rural Commercial Properties

Fire and smoke events may affect:

• Barns
• Equipment buildings
• Feed-storage areas
• Workshops
• Processing facilities
• Machinery
• Vehicles
• Agricultural inventory
• Outdoor work areas
• Surrounding soil

The assessment should consider the materials burned, property size, outdoor deposition, wind direction, drainage, and intended use.

Testing does not replace agricultural, veterinary, engineering, or food-safety evaluation when those specialties are required.

Wildfire Smoke and Ash at Commercial Properties

Oregon businesses may experience wildfire smoke infiltration or ash deposition even when the property is not directly threatened by flames.

Smoke and ash may enter through:

• Outdoor-air intakes
• Open loading doors
• Building entrances
• Gaps in the building envelope
• Mechanical systems
• Attached garages
• Employee and equipment movement

Exterior ash may affect:

• Equipment yards
• Vehicle fleets
• Loading areas
• Outdoor inventory
• Agricultural areas
• Stormwater pathways
• Building entrances

Testing may include selected interior surfaces, accessible HVAC components, exterior ash, or soil depending on the incident and investigation objectives.

Testing Before Commercial Cleanup

When practical, assessment and sampling should be considered before extensive cleaning, demolition, disposal, or inventory movement begins.

Pre-remediation documentation may help establish:

• Visible residue distribution
• Conditions outside the direct fire area
• Potential ventilation-system involvement
• Affected operational zones
• Categories of equipment or inventory
• Comparison locations
• A baseline for later assessment

Emergency stabilization and necessary safety measures should not be delayed solely for testing.

Photographs, videos, inventories, HVAC records, cleaning logs, demolition information, and lists of discarded materials should be retained whenever possible.

Post-Remediation Commercial Clearance Testing

After fire- or smoke-damage remediation, independent testing can help document selected accessible conditions.

The assessment may include:

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

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

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

Cross-Contamination During Commercial Remediation

Cleaning, demolition, equipment movement, and debris removal may transport particles outside the original work area.

Possible pathways include:

• Employees and contractors
• Tools and equipment
• Forklifts and vehicles
• Waste-removal routes
• Elevators
• Shared hallways
• Unsealed work areas
• Ventilation-system operation
• Inventory relocation
• Inadequate cleaning sequences

Post-remediation testing may include locations outside the reported work zone when cross-contamination is a concern.

Commercial Fire-Damage Insurance Claims

Independent testing may provide useful documentation during a commercial fire- or smoke-damage claim.

A report may identify:

• Incident information provided
• Areas assessed
• Observed conditions
• Potential smoke pathways
• Sampling methods
• Sample locations
• Laboratory findings
• Professional interpretations
• Investigation limitations

Testing may help document whether combustion-related residue was identified in selected areas, equipment, inventory, or accessible HVAC components.

5 Microns Inc. does not determine insurance coverage, liability, business-interruption losses, claim value, or policy interpretation.

Working With Multiple Parties

Commercial fire projects may involve:

• Property owners
• Business operators
• Tenants
• Facility managers
• Restoration contractors
• Insurance carriers
• Adjusters
• Public adjusters
• Attorneys
• Equipment specialists
• Industrial hygienists
• Engineers

Before testing begins, the project should identify:

• The client authorizing the work
• Property-access requirements
• Areas included in the assessment
• Intended recipients of the report
• Questions the investigation should address
• Testing limitations
• Payment responsibility
• Applicable scheduling constraints

5 Microns Inc. remains independent regardless of which authorized party retains our services.

Sample Identification and Chain of Custody

Commercial sampling records may include:

• Project information
• Sample numbers
• Collection dates
• Sampling locations
• Surface or material descriptions
• Requested analyses
• Sample collector
• Transfer or shipping information
• Laboratory receipt

Clear sample-location records are especially important on large properties containing multiple operational zones.

Chain-of-custody documentation supports sample identification and handling. It does not independently determine the source or significance of the material collected.

Understanding Commercial Testing Results

Laboratory results should be interpreted in relation to:

• Incident history
• Materials involved
• Facility operations
• Sampling method
• Sample location
• Surface type
• HVAC configuration
• Cleaning history
• Comparison samples
• Background sources
• Investigation limitations

A detected particle or compound does not automatically establish facility-wide contamination. Likewise, one negative sample does not establish that every unsampled surface, product, or component is unaffected.

Frequently Asked Questions

What types of commercial properties can you test?

Testing may be developed for offices, retail properties, restaurants, hotels, apartment complexes, warehouses, manufacturing facilities, agricultural buildings, and other commercial properties.

Can a business be affected if the fire occurred next door?

Yes. Smoke and combustion particles may enter through outdoor-air intakes, shared building pathways, open doors, ventilation systems, and gaps in the building envelope.

Can you test commercial HVAC systems?

Accessible HVAC components may be evaluated when the system could have collected or distributed smoke particles. Large properties may require assessment of multiple systems or zones.

Can equipment and machinery be tested?

Selected accessible equipment surfaces may be sampled. Environmental testing does not replace mechanical, electrical, engineering, or manufacturer-specific evaluations.

Can you test commercial inventory?

Representative items or inventory categories may be evaluated. A limited number of samples cannot automatically characterize every product in a facility.

Should testing occur before cleanup?

When practical, pre-remediation testing can document initial residue distribution and establish a baseline. Emergency stabilization and necessary safety measures should not be delayed solely for testing.

Can you perform post-remediation clearance testing?

Yes. Selected accessible areas may be assessed after fire- or smoke-damage remediation.

Can wildfire smoke affect a commercial property?

Yes. Wildfire smoke and ash may enter through ventilation systems, loading doors, outdoor-air intakes, entrances, and other pathways.

Can testing support a commercial insurance claim?

Testing can provide independent documentation of observations, sampling locations, and laboratory findings. It does not determine coverage, liability, business-interruption losses, or claim value.

Do you provide fire restoration or smoke cleaning?

No. 5 Microns Inc. provides independent assessment, sampling, laboratory coordination, and documentation. We do not perform restoration, cleaning, demolition, or reconstruction.

Does one sample represent an entire commercial property?

No. A sample represents its collection location. Larger properties may require multiple samples across different areas or operational zones.

Do you determine how the fire started?

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