Wildfire Smoke vs. Structure Fire Contamination
Why wildfire losses require a different approach to testing, cleaning, and restoration
Welcome to a special series of Ask Annissa. This month, we’re focusing on Preparing to Respond: Fire.
On this episode, Annissa answers a question submitted by Chris, a restorer looking to better understand the differences between wildfire smoke and structure fire contamination. Wildfire cleanup isn’t simply a larger version of structure fire restoration. Annissa explains that these two losses require different approaches, starting with the type of contamination.
Structure fires generally produce wetter, heavier, and more concentrated soot from materials burning inside the structure. Wildfire contamination, on the other hand, typically consists of lighter, drier ash and smoke residue that infiltrate the structure from the outside in.
Wildfire contamination may also be less visible, but that doesn’t mean it isn’t there. Annissa stresses that the absence of visible soot doesn’t mean the home is free of contamination. That’s why proper testing is critical. Depending on the loss, this may include dry cleaning sponge tests, spot testing, and attic inspections for ash. When needed, you can also bring in an industrial hygienist to help determine the extent of the contamination.
Successful wildfire restoration starts with proper testing, thorough documentation, and clear communication with the property owner. Annissa shares what you should look for, why proper assessment matters, and what you need to consider when approaching a wildfire loss.
Don’t forget to submit your questions and/or topics to Annissa at Annissa@FireHouseEducation.com with "Ask Annissa" in the subject line. You might be featured on a future episode. We will see you next week!
