Learn why smoke odor can return after proper fire damage restoration which includes deodorization limits and the science behind our perception of odor.

Emerging science reveals that lingering fire smoke residues may pose health risks similar to thirdhand tobacco smoke.

When you think of charred wood, ash left behind after a wildfire or soot, you might think that they are little more than harmless byproducts of incomplete combustion. Images of people sifting through the ash in their street clothes to find valuables, or walking through a burned-out home in shorts and flip-flops, gives the impression that post-fire environments are relatively safe. However, this is far from the truth.

In the fire restoration industry today, many practitioners use ozone generators as one of their primary means to neutralize smoke odor. Although ozone may be effective to some degree in neutralizing odors, many experts disagree on its effectiveness and whether the risks outweigh the rewards. So, what is ozone? And what are the associated health risks? Sean and Briana Scott examine the effects of ozone exposure and offer necessary precautions for working with ozone.

To better understand how toxic TCDD is, one needs to understand how it and other toxins are measured. In toxicology, the median lethal dose is identified as LD₅₀ (abbreviation for “lethal dose, 50%”).

In the fire restoration industry today, very little attention is given to the toxicity of volatile organic compounds (VOC’s), heavy metals, or the composition of particulate matter and smoke residues.

On April 15, 2019, fire broke out beneath the roof of the Notre-Dame de Paris Cathedral. Over 400 firefighters fought the blaze, which consumed approximately two thirds of the roof structure, including the 300-foot wooden spire.
