Firefighters battling the Iron Fire in Utah have potentially been exposed to lead and other dangerous contaminants, according to recent reports from ABC4 Utah. This alarming development highlights a hidden danger that many homeowners near wildfire zones may not realize — when structures burn, they release toxic materials including lead, asbestos, and other hazardous substances into the surrounding environment.
Utah faces unique environmental risks due to its combination of wildfire activity and older building stock. Many structures built before 1978 contain lead-based paint, and when these buildings burn, lead particles become airborne and settle on nearby properties. The same applies to asbestos, which was commonly used in insulation, roofing, and siding materials in older construction. MycoTest's state-by-state environmental hazard map shows elevated risk in Utah for these exact concerns.

What Contaminants Are Released During Wildfires?
When wildfires destroy homes and buildings, they create a toxic cocktail of substances that can travel far beyond the immediate burn zone. The most concerning contaminants include:
- Lead: Found in paint from pre-1978 homes, old pipes, and certain building materials
- Asbestos: Present in insulation, floor tiles, roofing, and siding in older structures
- Soot and ash: Contains a mixture of chemicals from burned plastics, treated wood, and household items
- Heavy metals: Released from electronics, appliances, and vehicles destroyed in fires
These materials do not simply disappear after the flames are extinguished. They settle as ash and dust on surrounding properties, where they can remain for months or even years if not properly addressed.
Why Homeowners Should Be Concerned
Even if your home was not directly damaged by the Iron Fire or other wildfires, your property may still be affected. Wind can carry contaminated ash and dust for miles, depositing it on roofs, siding, outdoor furniture, and soil. When residents track this material indoors, it can settle on floors, windowsills, and other surfaces where family members — especially young children — may come into contact with it.
Lead exposure is particularly dangerous for children, potentially causing developmental delays and learning difficulties. Adults can also experience health effects from lead exposure, including high blood pressure and kidney problems. The fact that professional firefighters on the Iron Fire required monitoring for potential lead exposure underscores how serious this contamination can be.
Steps to Protect Your Home and Family
If you live within several miles of a wildfire zone, environmental health experts recommend taking these precautions:
- Avoid disturbing ash: Do not sweep or blow ash, as this sends particles back into the air
- Wet cleaning only: Use damp cloths and mops to clean surfaces
- Test before renovation: If cleaning up fire damage, test materials before disturbing them
- Check outdoor areas: Gardens, play areas, and patios may need attention
- Monitor dust accumulation: Interior window sills and floors can harbor settled contaminants
The most important step is knowing what you are dealing with. Without testing, there is no way to know whether the ash and dust on your property contains dangerous levels of lead or other contaminants.
Frequently Asked Questions
Can wildfire ash contain lead even if no homes burned?
Yes, lead and other contaminants can be released when any structure burns, including sheds, vehicles, and commercial buildings. Lead is also naturally present in some soils and can become concentrated in ash. Testing settled dust and ash is the only way to know if your property is affected.
How far can wildfire contaminants travel from the fire zone?
Contaminated ash and particles can travel several miles depending on wind conditions. Homeowners living within 5-10 miles of a significant wildfire should consider testing their property, especially if they noticed ash accumulation during or after the fire.
What should I test first after a nearby wildfire?
Start with surfaces where ash visibly accumulated — outdoor furniture, window sills, and porch areas. For lead concerns, a dust wipe test can detect contamination on hard surfaces. For soot damage, testing can reveal whether professional cleaning is needed.
Utah homeowners concerned about potential contamination from the Iron Fire or other wildfires can take action today. MycoTest DIY Kits allow you to collect samples from your property and receive certified lab results, giving you the information you need to protect your family.
