Fire Safety & Smoke Damage
Soot Load
Quick Definition
Fine black carbon particles smaller than 1 micron that penetrate deep into lungs and HVAC systems
Soot load refers to the concentration of fine black carbon particles that result from incomplete combustion during wildfires. These particles are typically smaller than 1 micron, making them invisible to the naked eye but extremely harmful to health.
What You Need to Know
Soot particles are so small they bypass your body's natural filtration systems and penetrate deep into lung tissue. They also infiltrate HVAC ducts, spreading contamination throughout your home every time the system runs.
Why It Matters for Your Home
Fine soot particles carry other toxins like PAHs and heavy metals deeper into your respiratory system. Once in your HVAC system, they can continue circulating contaminated air for months after the initial smoke exposure.
How to Test for Soot Load
Professional testing uses microscopy combined with UV-VIS spectrophotometry to measure soot particle concentration in air and on surfaces. This provides accurate measurement of the invisible contamination in your home.
When to Get Professional Help
If your home experienced significant smoke exposure, professional soot testing can determine if HVAC cleaning and specialized air filtration are needed to remove these persistent particles.
