The Marshall Fire of December 2021 devastated over 1,000 structures near Boulder, Colorado, leaving some homes untouched by flames but infiltrated by smoke and ash. Research reveals that even homes spared from burning can harbor harmful chemicals released by combusted human-made materials, such as plastics and electronics. These substances, including volatile organic compounds (VOCs) like benzene and formaldehyde, linger on surfaces and in the air, posing health risks long after the fire.
A recent study surveyed residents returning to smoke-damaged homes and found that 55% experienced symptoms like headaches, coughing, and itchy eyes six months post-fire. While many noted reduced odors over time due to cleaning efforts, one-third of residents reported persistent symptoms even two years later. The proximity to burned structures correlated with increased health complaints, underlining the dangers of lingering toxins.
To mitigate risks, experts recommend cleaning smoke-damaged homes thoroughly, replacing HVAC filters, and using portable air purifiers. Protective measures like wearing N95 masks and gloves during cleaning are essential. As wildfires become more frequent, understanding and addressing the health impacts of smoke-damaged homes is critical for protecting residents’ long-term well-being.
