Few experiences can be as traumatic as a house fire. Fear and panic set in while you do your best to protect your loved ones. While this is a terrifying scenario, the danger is not over once the flames are extinguished. Not knowing about the risks lingering in the aftermath of a fire can cause you unnecessary stress.

We at Restore-It are very familiar with these invisible threats. As the experts in South Arkansas on fire damage restoration, we are here to explain the health consequences of soot and smoke.

Let's clear the air about the health risks of smoke and soot. In this article, we will talk about what makes smoke and soot so dangerous and learn how to create a safer environment after a fire. So, let's start!

What Makes Smoke and Soot so Dangerous?

When a house fire is put out, smoke and soot are left in the building. These complex mixtures contain various harmful substances. Understanding their composition will help explain why they pose such a threat. Let's take a look at them:

Particulate Matter

These are tiny solid particles and liquid droplets suspended in the air. Soot is a primary component of particulate matter from fire. These particles can be inhaled and impact your lungs and heart, according to the United States Environmental Protection Agency (EPA). Studies have shown that these particles can lead to several health problems, such as early death in people who have lung and heart diseases, non-fatal heart attacks, irregular heartbeats, worse asthma, reduced lung function, and more breathing troubles.

On the other hand, the American Lung Association warns that the health effects can be seen in both short and long-term exposure. Plus, while everyone is at risk upon exposure, some subpopulations are especially at risk, including:

  • Pregnant individuals
  • Babies, kids, and teenagers
  • Older adults (over 65)
  • People with respiratory problems like asthma and COPD
  • People with heart problems
  • People who are overweight or have diabetes
  • Current and former smokers

Gases

Smoke contains a variety of gases, including carbon monoxide, sulfur dioxide, nitrogen oxides, and volatile organic compounds like formaldehyde. Exposure to these gases will irritate and can be toxic at high concentrations. While everyone will be affected by the smoke, the EPA warns that some people are most susceptible to smoke, including:

  • children
  • teenagers
  • older adults
  • people with lung or heart disease 

Depending on what burned — plastics, treated wood, organic matter, or synthetic materials — hazardous chemicals can be released into the environment.

Immediate Health Effects Upon Exposure

People who are exposed to smoke and soot can experience immediate health effects. Far from a pleasant experience, your body will let you know something is not right, and we suggest you listen. Here is what you can expect after being in contact with smoke and soot:

Respiratory Irritation

Your airways are the first line of defense when you breathe in smoke and soot, and they can get really irritated, really fast. You may experience coughing, wheezing, shortness of breath, and a burning sensation in the throat and lungs.

Eye Irritation

Smoke can also mess with your eyes. They might start watering like crazy, trying to wash away the irritants. They can also burn and become red and bloodshot.

Skin Irritation

Your skin is another large surface that's affected when you come into contact with smoke and soot. It can get irritated too, leading to an annoying itching feeling. You might even break out in a rash, with red, bumpy skin.

Headaches and Nausea

Smoke isn't just particles; it's also full of gases, and some of those, like carbon monoxide, can cause headaches. You may feel dizzy, like the room is spinning. And you can also experience feelings of nausea.

Exacerbation of Existing Conditions

If you already have breathing problems like asthma or bronchitis, or a long-term lung condition like COPD, smoke and soot can make things much worse. It can trigger severe attacks, making it hard to breathe and causing a lot of distress.

Long-Term Health Consequences

Prolonged or repeated exposure to smoke and soot can have serious long-term health effects.

  • Respiratory Diseases: Chronic exposure can contribute to the development or worsening of chronic respiratory diseases, such as asthma, chronic bronchitis, and emphysema. The tiny particles can cause inflammation and damage to the lungs over time.
  • Cardiovascular Problems: Studies have linked long-term exposure to particulate matter with an increased risk of heart attacks, strokes, and other cardiovascular problems. The particles can enter the bloodstream and affect the heart and blood vessels.
  • Cancer Risk: Many of the chemical compounds found in smoke and soot are known or suspected carcinogens, increasing the long-term risk of various types of cancer, particularly lung cancer.
  • Neurological Effects: Some studies suggest a link between long-term exposure to air pollution, including smoke and soot, and neurological problems, especially in children and the elderly.
  • Weakened Immune System: Chronic inflammation caused by exposure to smoke and soot can weaken the immune system, making the body more susceptible to infections.

Your Smoke & Soot Safety Checklist

Protecting yourself and your loved ones from the dangers of smoke and soot is very important. Here are some actions to take, both right away and in the long run:

Immediate Actions

☐ Evacuate the affected area immediately.

☐ Do not re-enter until authorities say it's safe.

☐ Wear a respirator mask (N95 or higher) if you must be in the area.

☐ Cover all exposed skin.

☐ Wear eye protection.

☐ Increase ventilation by opening windows and using fans, if safe.

☐ Seek medical help for breathing problems or other worries.

Long-Term Strategies

☐ Hire a professional fire restoration company for thorough cleaning.

☐ Have your HVAC system inspected and cleaned by a professional.

☐ Replace air filters frequently.

☐ Throw away heavily contaminated items that can't be cleaned well.

☐ Watch for any long-term health effects and see your doctor if you're concerned.
