Smoke and Soot
A discussion of different types of smoke and soot contamination in ductwork.
The route of entry for this contamination to enter the HVAC System and Ducts
Gathering of evidence to support your findings.
Cleaning procedures and a practical way to prevent recontamination
Coatings and Deodorizers
Most importantly know who is paying you for the work
Smoke & Soot From A Fire
Soot and smoke from fires will include building materials as well as the homes contents. This will include everything from furniture to personal belongings bringing many different types of particulate into the smoke. This particulate can present many challenges to the HVAC Restoration project
Smoke/soot from fossil fuels
Oil Burner Malfunctions
Damaged Heat Exchangers
Gas Heating system malfunctions (That’s right, gas appliances can produce soot)
Blocked chimney flues
Fireplace back up
Wood and Pellet fuel burning appliances
Vehicle exhausts
Candles and Oil Lamps
Gas Fired Boiler Next To An Air Handler
This is a very sooty crown of a cast iron boiler- the picture onthe left is what it should look like. This was spilling soot intoa basement and getting drawn into leaky return ducts
Blocked chimney flues or poorly performing fireplace will allow smoke/soot to enter the indoor air instead of going up the chimney
Vehicle exhaust if too close to an air intake or if it can be drawn into the building can contaminate ductwork
Candles and oil lamps are large contributors to ongoing soot loss at homes and is sometimes misidentified as a heating system malfunction
Soot is the result of incomplete combustion of carbon- containing fuels, such as petroleum and its by-products. Paraffin, the waxy residue left behind in the refinement processing of petroleum, not only contains carbon but a host of other chemical compounds, some of which have been found to be toxic, and others labeled as carcinogens. Soy is the "solution to the pollution". First created in Iowa where most of the soybeans in the United States are grown, clean burning soy wax candles produce measurably less soot than traditional candles made from paraffin. Lower soot levels help maintain pure air quality and reduce home maintenance problems associated with soot deposits.
Smoke & Soot From A Protein Fire
Protein Fires
Smoke damage from the extreme charring or burning of a protein rich material- (Roast beef-chicken-turkey or even over boiled peas)
Produces little visible smoke
Has a rancid odor
Has an invisible film
Penetrates many areas of a home
May require hand cleaning
Smoke & Soot From Plastics Burning
Plastics fire
Many articles found in use today are made of plastic so if there is a structure fire most likely plastic is nearby
Normally has a heavy black soot
The soot can be sticky and require extra work cleaning
You most likely will have to do extensive cleaning to your equipment once the air duct cleaning is complete
Soot Presentation
Points of Entry of Soot into the HVAC System and Ductwork
Entry PointsThere are many entry points for soot contamination in HVAC systems. Soot, as an airborne contaminant in the environment has many different sources but they are all the result of a fire.
Common Entry PointsSoot can contaminate an HVAC system through many points of entry.
Common Entry PointsSoot can contaminate an HVAC system through many points of entry.
Common Entry PointsSoot can contaminate an HVAC system through many points of entry. Improperly installed duct connectors and grille connectors are contributors to soot intrusion into the ductwork.
Common Entry PointsSoot can contaminate an HVAC system through many points of entry. When fire dampers are braced open. In the event of a fire, smoke and soot will be transferred throughout the HVAC system.
Common Entry PointsThe most common point of entry would be through the return or cold air duct. When the HVAC system is operational and soot from external sources will be drawn into the system and contaminate the entire system.
Common Entry PointsAlso, when the system is running the location and source of the soot will be distributed throughout the entire occupied space.
Level of SootThis level of soot contamination is dependent on the source. Soot will contaminate the HVAC system even if it is not operational during the soot event. The HVAC system is the building respiratory system and therefore is constantly exchanging air throughout the occupied spaces due to differential temperatures.
Commercial BuildingsIn commercial building there are outside air intakes and return relief that, in certain circumstances, outside air intake will pressurize the Air Handling Unit (AHU) effectively simulating operation .
Modern TechnologyMany newer homes now have Heat Recovery Ventilators installed and also will be effected by the outside air. The HVAC system can be operating in the FAN ON mode, constantly moving air and exchanging outside/inside air.
Building EfficiencyWhen the system is not operational, hot and cold air from inside and outside sources effect the flow of air within the occupied space and the Air Handling Unit and ductwork.
Cold air falls and hot air rises. Outside air can also be drawn into the occupied space through windows, exterior doors and exterior gaps in light fixtures, vent, cracks, etc. Warm air from cooking, other heat sources will rise in the air and pressurize the ductwork in ceiling mounted supply and return air grilles.
Air MoversCeiling and whole house fans operating will contribute to distribution of soot throughout the house and inside the HVAC system and ductwork.
Evidence of Soot Contamination – Supply GrillesA visual inspection of the affected areas of the home will provide simple evidence of contamination of the interior of the HVAC System.
Evidence of Soot Contamination – Supply GrillesA visual inspection of the affected areas of the home will provide simple evidence of contamination of the interior of the HVAC System.
Evidence of Soot Contamination - Internal ComponentsVerification of internal evidence of contamination requires the opening, access and possible removal of some components to verify soot contamination.
Evidence of Soot Contamination - Internal ComponentsCheck the return air filter grille and filter. Grille surface may be visibly clean. Opening will expose the back side and the filter face.
Evidence of Soot Contamination - Internal Components
Often you will have to pull the blower assembly to thoroughly inspect the interior of the Air Handling :Unit.Disassembly will expose fire/soot damage on the internal components.
Evidence of Soot Contamination - Internal ComponentsRemoval of the ceiling grilles will expose the interior of the ductwork. Simply by placing a digital camera into the opening you can get images of the interior of the ductwork for verification of contamination.
Evidence of Soot Contamination - Internal ComponentsSoot contaminated return grille and coils on a system that was not running during a fire. There is visible existing dust and soot located on the right side of the coil next to the return.
Evidence of Soot Contamination - Internal ComponentsReturn air grilles located in a commercial ceiling. System was not operational darning the fire. Filter comparison of two that are soot contaminated and the middle unused.
Evidence of Soot Contamination - Internal ComponentsFiberglass duct board accessed for interior inspection shows traces of soot contamination. Running you hand across the edge of the opening shows soot deposits.
Evidence of Soot Contamination - Internal ComponentsReturn grille, filter and flex. Soot damage on grille and filter. Heat was hot enough to melt flex.
Evidence of Soot Contamination - Internal ComponentsAccess to cleaning supply shows liner soot damaged and suitable for cleaning. Inspection further up the line where it went horizontal, the liner melted from heat.
•Source Removal Air Duct Cleaning•Same Stuff Different Day
Special Conditions (Obstacles) Presented by Fire Losses:
• Contamination is not like what is normally encountered in general maintenance cleaning situations.
• Smoke film residue, depending upon what burned, may not come off with dry cleaning techniques.
• Special techniques, products, and tools may be required to accomplish the goal of satisfactory decontamination.
The duct materials upon which the smoke residue is deposited can present problems.
• It may not be able to withstand the aggressive cleaning measures that may be required.
• They may be an odor sink.
A worst case scenario may present only 2 choices:
Outright replacement instead of cleaning.
Heavy spray coating after aggressive cleaning. That still may not be adequate and replacement might be necessary.
Extraordinary amounts of soot from smoke can make cleaning problems.
This system was not running during the fire. This was from the pressure of the smoke entering the return grill in the overhead at the location of the fire.
Post Cleaning Protection
Applying a filter media over the registers/diffusers and grills will keep any “float” from re-entering the ductwork and prevent a “call back”

Coatings for Fire/Soot
“Following cleaning, any component surface exhibiting damage due to heat exposure must be restored to an acceptable condition or replaced.”
Never used in lieu of cleaning, source removal
Can help secure loose fibers
Some fires, cleaning alone may never get rid of odor
Residual particulate can be perceived as odor
When heat is turned on, systems open up and breathe
Deodorizing
Often used as a “final” treatment
Best understood by examining how product works
Fundamental distinction – are you absorbing the odor, or just masking it
Perfume/Masking Scent
Pulldown via wetting and gravity
Pulldown via chemical bonding
Sprayed or fogged
Thermal vs Cold
The debate continues
Follow the smoke from the source, then fog beyond it

Centers of Influence for Insurance Work
Restoration Contractors
Insurance Adjusters
Insurance Agents
HVAC Companies
Making sure you get paid !
We will be discussing how to know who you’re working for and whose policy is covering what. This is important with landlord tenant situations, condominiums as well as commercial buildings. The people that had the loss may not be the ones with the policy to cover your work.
Commercial Buildings
Who’s responsible for the air duct cleaning ?
Part of the structure or part of the contents
Were the air ducts there before the tenant build out ?
Questions? Have the tenant check out their lease
Working with Restoration ContractorsResidential
Commercial
Estimate
Schedule
Invoice
Try to be involved in the negotiations with the adjuster
Estimate with or without blueprints
Detailed scope
Time table for completion
Leave room for changes and unknowns
First off, unless someone buys direct from their insurance company they buy their insurance from an agent and all their dealing are with their agent. I find that very few insured know who the actual companies are that are writing their policy.
Insurance Company and Agents sell Policies (independent agents represent many different insurance companies)
Different types of adjustersInsurance Adjusters adjust claims
1. Assist in determining cause of loss
2. Determine if it is a covered loss
3. Assign values
Company Adjusters
1. Work inside office at insurance company
May assign a company field adjuster
May assign an Independent adjusting company
May hire a consultant to determine cause and origin of loss and its value
Company Field Adjusters

Public Adjuster
Works for the Policy Holder to adjust the claim
Is charged a percentage of the claim for their work
Used when the policy holder and insurance company disagree on the loss and value ( kind of like an attorney for the insured)

Authorization to Perform Services and Direction to Pay
This is something we have signed prior to doing the work. It lets the insured
know that we are working for them and not the insurance company and if
their claim is denied they owe us the money. We always get approval from
the adjuster prior to the work, but sometimes things change and it may not
be covered or it may be the wrong policy, this lets the insured know we are
working for them and not their insurance company.
Additionally, it directs the insurance company to pay us directly instead of
sending the check to the insured. This does not always happen but it is a
legal document that will help when and if you have to collect from them.
The insurance company will sometimes pay us direct, but they have the
insured’s name on the check. Our form states that we can act as their
Limited Power of Attorney and sign their name to the check if this occurs.
