Los Angeles Firefighters’ Cancer Fears After Fighting Major Fires
As far as he was looking, the houses were on fire, everywhere,
said Firefighter Joseph field, 50, who has been with the Los Angeles Fire Department for more than 25 years. Nothing I have seen was like that night.
Field, who drove a 25 cm hose line, launched a water curtain on a house that had not yet caught fire.
Two meters away, the neighboring house was filling with smoke.
Even with glasses, smoke irritants made their eyes feel like rubbing with sandpaper.
You are basically using a fabric hood to help a little, but you’re inhaling a lot of smoke,
Field said. You’re simply swallowing it. You’re constantly swallowing it.
At one point, he had to retreat and find a cleaner air pocket on a porch.
I couldn’t breathe,and I was trying to recover my breath and coughing,
he said.
the wind was so strong that the water from the hose only reached less than 1 meter before being blown back.
you just start losing it. (Fire) begins to enter the house, despite your best efforts,
he recalled.
Field helped fight the fires for seven consecutive days,took one day off,and then returned for eight more days.
We are not accustomed to being swept into a fire,
he said. This fire, for the most part, defeated us all.
The Palisades fire in Los Angeles is classified as the second most destructive forest fire in the history of southern California, with more than 9,308 hectares and 5,000 burned structures. So many structures burned together, with so many unknown contents: plastics in furniture, batteries in cars.
Now, Field wonders what could be burning inside him.
many boys say that it is problably a lot, a couple of years of our life, with the amount of things we absorb,
he said. You can only absorb so many bad things.
Field is one of 300 firefighters participating in a study to monitor their exposure to carcinogenic chemicals after Los Angeles fires.
Researchers have collected samples of blood and urine from firefighters from the Department of Silviculture and Fire Protection of California, the Los Angeles Fire Department, and other smaller departments. they have also collected contaminant absorbent bracelets that firefighters used to measure their exposures.
A recent study by the Centers for disease Control and Prevention (CDC) indicated a notable, albeit brief, increase in airborne lead levels during fires in Los Angeles. The study, released in February, noted a surge of 110 times the normal lead concentration. The CDC acknowledged that the long-term health implications of such exposure events remain unclear,particularly given that many buildings in the affected areas predate 1978,when lead paint was still in common use.
During the Palisades fire,over 6,000 firefighters were deployed.
Exposure to carcinogens from such incidents can be significant.
Exposure to carcinogens after the attacks of September 11, 2001 has been related to a higher risk of cancer. according to the New York City Fire Department, 3,500 firefighters have cancer related to their work in the World Trade center.
Concerns have been raised about the specific nature of air, soil, and water pollution in Los Angeles following such events.
According to the International Fire association, two-thirds of firefighter fatalities are attributed to work-related cancer.
It is a fairly shocking statistic, but it is the reality of what we face in the Fire Service as a result of our occupational exhibitions,
said a scientific advisor from the association. Any exposure to combustion products increases the risk of cancer, and (Los Angeles fires) were obviously quite substantial exhibitions.
Forest firefighters also face regular exposure to carcinogens; research has linked at least 29 carcinogens to this type of fire.
Firefighters battling blazes that spread into urban environments encounter even more hazardous emissions from the combustion of both natural materials and man-made products.
Following the initial fire, these firefighters contend with “degassing,” the release of harmful gases from the smoldering debris, which can persist for days or even weeks.
The complex mixture of toxins present in southern California fires distinguishes them from typical forest or structural fires,according to an occupational health researcher.
We really do not wholly understand the long -term effects of these exhibitions to carcinogens,
the researcher stated. We definitely need more studies.
Cancer can take decades to manifest after exposure to carcinogens.
Let’s say you are exposed to these carcinogens at age 20. Then, maybe at 40 or 50 years, you could find those cancers,
the researcher explained.
Studies are underway to identify interventions that can be implemented to help firefighters understand and mitigate their cancer risk.
The practicality of forest firefighters wearing full-face masks with filter cartridges and battery packs is limited,given the demanding conditions and heavy equipment they carry. often, they have only a handkerchief or hood for respiratory protection.
That is not a respiratory protection device. Let everything pass great pieces of ash,
an expert noted.
Furthermore, current mask cartridges are not certified to protect against the complex smoke composition encountered by these firefighters. Even high-quality N95 masks can quickly become ineffective.
All cartridges that exist are certified and tested against individual gase challenges,
a scientific advisor explained. The problem with smoke is that it is an extraordinarily complex mixture of many, many, many, many gases. And the problem of trusting only a mask is that we do not know.

Researchers and firefighters are investigating the long-term health impacts of exposure to smoke and carcinogens during wildfires, and exploring ways to mitigate the risks.
Firefighters face significant health risks from exposure to smoke and other toxins during wildfires. Concerns are rising about the potential long-term effects, including increased cancer risk.
One firefighter noted the importance of understanding the effectiveness of current protective gear: how effective they are against smoke exhibitions, if they are.
Researchers at the Wildlife Conservancy have been conducting field tests for the past year to evaluate the effectiveness of various respiratory devices. These tests consider the real-world conditions firefighters face, including the presence of beards, sunscreen, ash, soot, smoke, and sweat.
The Wildlife Conservancy is also studying clothing designed with an additional barrier to filter out tiny particles. Laboratory tests have shown up to a 95% reduction in skin pollution from fire exposure when using this type of clothing.
one firefighter, after spending a week battling a fire, described his routine for cleaning his gear: he soaked his scrub jacket in a bucket of water and detergent.
It seemed oil, mud. All those carcinogens, remove them.
Reflecting on efforts to protect homes during a recent fire,the firefighter stated:
There were houses that,if we had not made an effort in those houses,would definitely have burned,and if those houses burned,they would have burned many more houses. In fact, we save several houses.
He added that this outcome was positive.
However, the long-term health consequences of firefighting are not always at the forefront of immediate concerns.
When asked about the potential future health risks, the firefighter responded:
I don’t try to think too much about things like that. When I face such things, then it will be another story, and I will face it when that happens.
Firefighters’ Health Risks: Exposure to Toxins and Protecting the Protectors
Researchers and firefighters are investigating the long-term health impacts of exposure to smoke and carcinogens during wildfires, and exploring ways to mitigate the risks.
What are the Major Health Risks Faced by Firefighters?
Firefighters face notable health risks from exposure to a complex cocktail of toxins during wildfires and structural fires. These include:
- Carcinogens: Substances that can cause cancer.
- Particulate Matter: Tiny particles in smoke and ash that can irritate the respiratory system and lead to lung damage.
- Toxic Gases: Carbon monoxide, hydrogen cyanide, and other gases that can cause immediate health problems.
- Heavy Metals: Lead, often released from burning structures, can create serious complications.
The combination and concentration of these toxins vary depending on the type of fire (wildfire vs. structure fire) and what materials are burning.
Why is Smoke Exposure so Hazardous for Firefighters?
Smoke exposure is exceptionally dangerous due to the sheer variety of harmful substances it contains. During wildfires, especially in urban interfaces, the combustion of natural materials and man-made products releases a dangerous mix of toxins. Even with protective measures, the intensity of exposure can be overwhelming. Such as, firefighters frequently enough experience:
- Eye and Respiratory Irritation: Burning eyes and difficulty breathing are initial signs of exposure.
- Constant Inhalation: Even with hoods or rudimentary protection, firefighters often constantly swallow smoke, increasing exposure.
- Prolonged Exposure: Many firefighters work long hours and multiple days combating wildfires thereby extending their exposure.
- “Degassing”: Even after the flames are extinguished, smoldering debris continues releasing harmful gases.
As one firefighter mentioned regarding the wind in the Palisades fire, “the wind was so strong that the water from the hose only reached less than 1 meter before being blown back”.
How Does Smoke Exposure Contribute to Cancer Risk in Firefighters?
Exposure to carcinogens in smoke significantly increases firefighters’ risk of developing cancer. Research has linked at least 29 carcinogens to wildfires.
- Carcinogens in Smoke: Fires release a wide range of carcinogens from burning materials.This includes asbestos which is a known carcinogen linked to mesothelioma and lung cancer.
- long Latency Period: Cancer often takes decades to develop after exposure to carcinogens. This means the health effects may not appear for many years.
- Elevated Risk: Studies suggest that firefighting is linked to a higher risk of several types of cancer, according to The International Fire Association.
According to the International Fire Association, two-thirds of firefighter fatalities are attributed to work-related cancer. This is a shocking statistic that reflects the realities of exposure in the line of duty.
What Are the Specific Toxins Found in Wildfire Smoke?
Wildfire smoke contains a complex mix of harmful substances. Some notable examples include:
- Particulate Matter (PM2.5): Fine particles that can penetrate deep into the lungs.
- Polycyclic Aromatic hydrocarbons (PAHs): Carcinogenic compounds.
- volatile Organic Compounds (VOCs): Chemicals that can cause a variety of health effects.
- Heavy Metals: Lead and other metals released from burning materials.
- Asbestos, which is a known carcinogen.
the composition varies greatly depending on what is burning (trees, homes, plastics, etc.). A surge in airborne lead was documented during the Palisades fire in Los Angeles, with concentrations 110 times the normal level, highlighting another danger.
How Effective is current Protective Gear for Firefighters?
The effectiveness of current protective gear is a critical concern, particularly sence smoke composition is complex and gear isn’t perfectly designed to counteract it. The challenges include:
- Limited Protection: Handkerchiefs and hoods offer minimal respiratory protection.
- Incomplete Filtration: Current mask cartridges are not certified for the complex mixtures found in smoke.
- Real-World Conditions: Beards, sweat, and ash can compromise the seal and effectiveness of masks.
- Swift Ineffectiveness: Even high-quality N95 masks do not hold up to the extreme exposure.
As one expert remarked, “That [hood] is not a respiratory protection device. Let everything pass great pieces of ash.”
What Research is Being Done to Protect Firefighters?
Extensive research is aimed at protecting firefighters. Key areas include:
- Exposure Studies: Studies monitor firefighters’ exposure to carcinogenic chemicals after fires. Such as, in the Los Angeles region blood and urine samples are collected from firefighters.
- Protective Gear Growth: Testing and development of more effective respiratory devices and clothing designed to filter particles are underway.
- Intervention Strategies: Research seeks to develop ways to help firefighters understand and mitigate their cancer risk.
Summary Table: Firefighter Risks and Protective Measures
| Risk Factor | Health Impact | Protective Measures (Challenges) |
|---|---|---|
| Smoke Exposure | Eye/Respiratory Irritation, Increased Cancer Risk | Hoods, Masks (limited effectiveness, complex smoke composition) |
| Carcinogens | Cancer (Long latency period) | Research, Monitoring Exposure |
| Particulate Matter | Lung Damage, Respiratory Issues | Clothing with Filters |
| Toxic Gases | Immediate health problems | Masks, limited protection |
What is the Situation For Firefighters After 9/11?
The events of September 11, 2001, and subsequent attacks on the World Trade Centre have also yielded critical data of the health impacts of firefighting.
- Increased cancer risks: Exposure to carcinogens after the attacks has been related to the higher cancer rates.
- Mortality: There is a significant increase in firefighters that are impacted by job related cancer. According to data released by The New York City Fire Department, roughly 3,500 firefighters have cancer related to their work.
Is There a Psychological Toll on Firefighters?
The nature of firefighting may cause firefighters to adopt a position of not thinking about consequences, and to focus on the tasks at hand.
When I face such things, then it will be another story, and I will face it when that happens.
