Leading Colorado’s Fight for Truth and Accountability: Protecting Your Rights Against Toxic Exposure and Unsafe Industries

For decades, the men who descended into the uranium pits of the Western Slope and the pipefitters who maintained the high-pressure lines at the Suncor refinery in Commerce City inhaled substances their employers knew would eventually destroy their lungs. While workers built Colorado’s energy and infrastructure from Pueblo to Greeley, multinational corporations kept measurements of benzene, asbestos, and radiation in locked filing cabinets, allowing Colorado families to bear the burden of a terminal diagnosis years later.

If you are struggling with a diagnosis of mesothelioma, leukemia, or a catastrophic workplace injury, we understand that you aren’t just looking for a lawyer. You are looking for an explanation for why this happened to you and a team that has the strength to stand up to the companies that let it happen. At Attorney 911, led by Ralph Manginello and backed by the insider knowledge of former insurance defense attorney Lupe Peña, we make it our mission to turn that confusion into a path toward justice.

Colorado has a proud history of hard work, from the deep-rock mines of Leadville to the sprawling construction sites currently transforming the Denver skyline. But that history has often come at a heavy cost to the people who did the work. Whether you were exposed to asbestos at the Rocky Flats site, handled “forever chemicals” at Peterson Space Force Base, or suffered a scaffold fall in downtown Denver, your rights aren’t a relic of the past. We use our 27+ years of experience and our history of litigating against the world’s largest energy companies to fight for every dollar you and your family deserve.

Why the Fight Against Corporate Negligence Requires an Insider’s Perspective

When we take on a toxic exposure or industrial injury case in Colorado, we aren’t just fighting a company; we are fighting an entire specialized defense infrastructure. Large employers and product manufacturers in the Front Range transition from “safety-first” slogans to aggressive legal denial the moment a worker gets sick.

This is where our firm provides a “nuclear” advantage. Our associate attorney, Lupe Peña, spent years on the other side of the aisle. He worked for a national defense firm, learning exactly how insurance companies and corporate legal teams evaluate, suppress, and ultimately try to dismiss toxic exposure claims. He has seen the playbook they use to undervalue a life. Today, he uses that exact knowledge to build a shield around our clients, anticipating the defense’s every move before they even make it.

Founding attorney Ralph Manginello brings nearly three decades of trial experience to the table, including federal court admission to the U.S. District Court. Ralph was part of the litigation team that held BP accountable for the Texas City Refinery explosion—a $2.1 billion total case. This level of experience means we are never intimidated by the size of a defendant. If we can take on a global oil giant and win, we can handle the company that exposed you to toxins here in Colorado.

As Ralph explains in our guide to high-value personal injury claims, toxic exposure cases are unique because the harm is often hidden for years: https://www.youtube.com/watch?v=dmMwE7GqUFI

The Anchor of Our Practice: Mesothelioma and Asbestos Exposure in Colorado

Asbestos is not just a building material; in the context of Colorado’s industrial landscape, it is a legacy of betrayal. While the general public often thinks of asbestos as a problem of the 1970s, many workers at Colorado power plants, refineries, and military bases were exposed to these deadly fibers well into the 1990s—and the resulting diagnoses of mesothelioma are only now surfacing.

The Biological Reality: How Asbestos Fibers Destroy Tissue

To understand why you are sick, you have to understand the microscopic war happening in your chest. When a worker at a Denver power plant or a Colorado Springs construction site cuts into old pipe lagging or handles heat gaskets, they release millions of microscopic fibers into the air.

Asbestos fibers—particularly the needle-like amphibole varieties—are “biopersistent.” This means that unlike organic dust, your body cannot break them down. When you inhale them, they travel deep into the lower lobes of the lungs and migrate to the pleura, the thin lining that surrounds your lungs and chest cavity.

Your immune system identifies these fibers as foreign invaders and sends macrophages (scavenger cells) to engulf and destroy them. However, because the fibers are often longer than the cells themselves, the macrophages undergo “frustrated phagocytosis.” The cells die while trying to swallow the fiber, releasing toxic reactive oxygen species (ROS) and inflammatory cytokines like TNF-alpha and IL-1-beta directly into your lung lining.

This creates a cycle of chronic inflammation that lasts for decades. Over 20 to 50 years, this constant irritation causes repeated DNA damage to the mesothelial cells. Eventually, crucial tumor-suppressor genes like BAP1 are deactivated, and the cells undergo a malignant transformation into mesothelioma.

The National Cancer Institute provides a detailed fact sheet on how this cellular damage progresses: https://www.cancer.gov/about-cancer/causes-prevention/risk/substances/asbestos/asbestos-fact-sheet

The Colorado Exposure Map: Where the Fibers Were Found

Many of our clients in Colorado were exposed at sites that were supposed to be safe. Some of the most common exposure pathways in the state include:

• Public Utility and Power Plants: Facilities like the Cherokee and Zuni generating stations used massive amounts of asbestos insulation on boilers, turbines, and steam lines. We look at the records of companies like Public Service Company of Colorado (now Xcel Energy) to identify when and where workers were put at risk.
• The Suncor Refinery (Commerce City): As with any refinery, the high-heat processes at Suncor relied on asbestos gaskets, packing, and insulation for decades. Pipefitters and maintenance workers in Commerce City were frequently exposed during turnarounds and routine repairs.
• The Rocky Flats Site: This former nuclear weapons facility was a nexus of both radioactive and asbestos hazards. Workers handling plutonium also worked in buildings saturated with asbestos fireproofing and insulation.
• Libby Asbestos in Denver: Many people don’t realize that vermiculite from the infamous W.R. Grace mine in Libby, Montana, was shipped to processing plants in Denver. Facilities like the Western Minerals plant in Denver processed this tremolite-contaminated material, exposing both the workers and the surrounding neighborhoods.

The Dual-Path to Compensation: Trust Funds and Litigation

If you’ve been diagnosed with mesothelioma, you may feel like it’s “too late” or that the company you worked for is long gone. But your rights outlast a corporation’s lifespan. We pursue a dual-track strategy to maximize your recovery:

1. Asbestos Bankruptcy Trusts: More than 60 trusts exist today, holding approximately $30 billion in assets specifically for victims like you. These trusts were created by companies like Johns-Manville, Owens Corning, and W.R. Grace as part of their bankruptcy reorganizations. While these trusts have specific hurdles, we know exactly how to document your work history to satisfy their requirements.
2. Civil Litigation: Many asbestos defendants remain solvent and can be sued directly in court. This often leads to significantly higher recoveries than trust funds alone.

As Ralph Manginello explains, these cases often meet the criteria for “million-dollar cases” due to the severity of the diagnosis and the clear history of corporate negligence: https://share.transistor.fm/s/d690a218

The Front Range Construction Boom: Silica and Engineered Stone Risks

Colorado is currently experiencing one of the longest sustained construction booms in its history. While new high-rises and suburban developments define the I-25 corridor, they are also producing a new, younger generation of victims: workers diagnosed with accelerated silicosis.

The “Next Asbestos”: Why Engineered Stone is Lethal

Many kitchen and bathroom remodels in Colorado now use “engineered stone” or quartz countertops. These products, manufactured by companies like Caesarstone and Cosentino, contain upwards of 90% crystalline silica. When a fabrication worker in Colorado cuts, grinds, or polishes these slabs without high-level dust suppression, they inhale massive amounts of respirable crystalline silica dust.

Much like asbestos, silica particles are cytotoxic. When they reach the alveoli (air sacs) of the lungs, they kill the macrophages that try to clear them. This releases a cascade of inflammatory mediators that recruit more immune cells, leading to a permanent, irreversible scarring of the lung tissue known as fibrosis.

Because the silica content in engineered stone is so much higher than in natural granite, workers in their 20s and 30s are being diagnosed with “accelerated silicosis” after only 5 to 10 years on the job. Many of these young men in the Denver metro area are currently on lung transplant lists—victims of an industry that failed to provide the necessary wet-cutting tools and respiratory protection.

The CDC’s Morbidity and Mortality Weekly Report (MMWR) has specifically documented this epidemic among stone fabrication workers: https://www.cdc.gov/mmwr/volumes/72/wr/mm7238a1.htm

We understand the cultural dynamics of this workforce. Many of these workers are part of Colorado’s vibrant Hispanic community. If you were told by an employer that “dust is just a part of the job,” they were wrong—and they were breaking federal law. Lupe Peña is bilingual and provides a direct, no-language-barrier connection for our Spanish-speaking clients. Hablamos Español.

As Chad H. shared in his verified Google review: “A true PITT BULL and fighter. He don’t play!… Atty. Manginello and I had DIRECT COMMUNICATION on my legal issue.” That same tenacity is what we bring to every silica claim in Colorado.

The Rocky Mountain Nuclear Legacy: RECA and Radiation Claims

Colorado played a central role in the Cold War, and that role left behind a landscape of toxic exposure that continues to impact families across the state. From uranium mining on the Western Slope to nuclear production at Rocky Flats, the “Atomic Age” in Colorado was built on the health of its workers.

Uranium Mining and the Western Slope

Miners in towns like Uravan and Grand Junction spent decades pulling ore from the earth to fuel the nation’s nuclear arsenal. They inhaled radon gas and uranium dust, which are direct carcinogens. For many of these miners and their families, the health impacts—including lung cancer and pulmonary fibrosis—didn’t appear until long after the mines closed.

The Radiation Exposure Compensation Act (RECA)

If you worked in a uranium mine or a processing mill in Colorado between 1942 and 1971, you may be entitled to a lump-sum payment of $100,000 under RECA. This program was recently expanded and extended. It is a critical source of compensation for “Atomic Veterans,” uranium workers, and “Downwinders” who were exposed to radioactive fallout.

However, RECA is only one part of the picture. Many Colorado workers were also exposed to silica, asbestos, and hazardous chemicals at these same sites. We investigate whether you have additional claims against private contractors who managed these sites and failed to protect you.

The Department of Justice provides the official guidelines for RECA eligibility here: https://www.justice.gov/civil/common/reca

Benzene and Chemical Exposure: The Suncor Refinery and Colorado Rail Yards

While the mountains are what most people think of when they picture Colorado, the industrial belt in Commerce City and the bustling rail yards in Denver and Pueblo are centers of chemical exposure.

Benzene and the Blood: How it Causes Cancer

Benzene is a fundamental component of crude oil and a common industrial solvent. At the Suncor refinery or in the rail yards where BNSF and Union Pacific operators maintain locomotives, benzene exposure is a silent but constant threat.

When you breathe in benzene vapor, your liver metabolizes it into several highly toxic compounds, including muconaldehyde and p-benzoquinone. These metabolites travel through your bloodstream to your bone marrow—the factory where your blood is made. Once there, they cause specific chromosomal translocations, such as t(8;21), that interfere with how blood cells mature.

The result is often Acute Myeloid Leukemia (AML) or Myelodysplastic Syndrome (MDS). These aren’t “accidents”; they are the result of cumulative exposure levels that often exceed the OSHA permissible exposure limit (PEL) of 1 ppm.

OSHA detail on benzene regulations can be viewed here: https://www.osha.gov/laws-regs/regulations/standardnumber/1910/1910.1028

If you were a refinery technician or a railroad worker in Colorado and have been diagnosed with a blood cancer, we look at the industrial hygiene records the company kept. As Ralph explains in our podcast on high-value settlements, these cases depend on proving that the company had the data and chose to ignore it: https://share.transistor.fm/s/aea9f03e

Dangerous Industry Injuries: Front Range Construction and Agriculture

Beyond toxic exposure, Colorado’s most dangerous industries claim hundreds of workers each year through catastrophic physical accidents. Whether you are on a high-rise in Cherry Creek or a ranch in Eastern Colorado, your injuries are governed by strict safety standards that were likely ignored.

Construction: Falls, Cranes, and Trenches

Construction remains the deadliest industry in Colorado. The “Fatal Four”—falls, struck-by, electrocution, and caught-in-between—account for the vast majority of local fatalities.

• Scaffold Falls: In Denver, we often see injuries where a subcontractor failed to properly erect a scaffold or provide a personal fall arrest system (PFAS). Under OSHA 29 CFR 1926.451, the duty for safety falls squarely on the employer and the general contractor.
• Trench Collapses: No worker in Colorado should ever die in a trench. Federal law is crystal clear: any excavation deeper than 5 feet MUST be shored, sloped, or shielded. When a trench collapses on a job site in Aurora or Colorado Springs, it is almost always the result of a “competent person” failing to do their job.
• Crane Safety: As the Denver skyline grows, so does the presence of tower and mobile cranes. A crane collapse is a structural failure that often relates to improper ground assessment or weather-related negligence.

Ralph Manginello’s guide to construction accidents in major metro areas provides a framework for how we investigate these site-wide failures: https://www.youtube.com/watch?v=OqYeRjbR9PI

Third-Party Liability: Getting Around the Workers’ Comp Trap

If you were hurt on the job in Colorado, your employer likely told you that workers’ compensation is “all you can get.” They are counting on you not knowing about third-party liability.

While you generally cannot sue your direct employer in Colorado for negligence, you CAN sue third parties who contributed to your injury. This includes:

• The manufacturer of a defective tool or scaffold.
• The property owner who allowed a dangerous condition.
• A general contractor who supervised a dangerous site.
• An equipment maintenance company that failed to inspect a crane.

Third-party claims are vital because workers’ comp only pays medical bills and a portion of lost wages. A third-party lawsuit allows you to recover for pain and suffering, emotional distress, and full future earning capacity.

Military Exposure: PACT Act and PFAS in Colorado

Colorado is home to several major military installations, including Buckley Space Force Base, Fort Carson, and the Air Force Academy. For our veterans, “the mission” often came with hidden health hazards.

Firefighting Foam (AFFF) and “Forever Chemicals”

The military and many Colorado airports used Aqueous Film-Forming Foam (AFFF) for fire training for decades. This foam contained PFAS—polyfluoroalkyl substances that do not break down in the body. These chemicals have migrated into the groundwater around Colorado Springs and Fountain, affecting thousands of residents and service members.

PFAS exposure is linked to:

• Testicular and kidney cancer.
• Thyroid disease.
• Ulcerative colitis.
• Suppressed vaccine response.

The PACT Act and Colorado Veterans

Under the Honoring Our Promise to Address Comprehensive Toxics (PACT) Act of 2022, veterans exposed to burn pits, radiation, and AFFF now have a streamlined “presumptive” path to VA benefits. If you served in Iraq or Afghanistan and now have a respiratory cancer or chronic sinusitis, the law now assumes your service caused the illness.

We assist Colorado veterans in ensuring their VA disability claims are filed correctly, while simultaneously pursuing civil litigation against the civilian contractors and chemical manufacturers who produced these toxic substances. Your service to this country shouldn’t include a lifetime of medical debt.

The VA’s official PACT Act resource can be found here: https://www.va.gov/resources/the-pact-act-and-your-va-benefits/

From the Inside Out: How We Counter the Defense Playbook

Corporate defendants have a multi-layered strategy for defeating toxic exposure claims. Because Lupe Peña knows this strategy from his time in insurance defense, we are ready for their tactics before the first motion is filed.

Common Defense Tactics and Our Counters:

1. “You Can’t Prove Our Product Caused It”: In asbestos and chemical cases, companies will argue that because you used many products, you can’t blame theirs. We use the “substantial factor” test. We don’t have to prove their fiber was the only one—just that it played a significant part in the total dose.
2. “The Statute of Limitations has Passed”: They will try to claim you waited too long. We rely on the Discovery Rule. In Colorado, the clock for a toxic tort doesn’t start until you discovered the illness and its cause. This means a 40-year-old exposure is still a valid claim.
3. “Junk Science” Challenges: They will hire “expert” witnesses to say the substance you were exposed to isn’t dangerous. We counter with board-certified toxicologists and oncologists who cite IARC and NIOSH standard authorities.
4. The “Lifestyle” Blame: If you have lung cancer, they will blame your smoking. We prove that asbestos and smoking have a “synergistic” effect—the asbestos made the smoking 50 times more dangerous, meaning the asbestos company is MORE liable, not less.

As Leonor, our lead case manager, explains, documentation starts the moment you call: https://share.transistor.fm/s/a85410a7

Understanding Damages: What is Your Colorado Case Worth?

When we calculate the value of a toxic exposure or industrial injury case in Colorado, we look at the totality of the destruction. Past results do not guarantee future outcomes, but the ranges in this field reflect the seriousness of the harm.

• Mesothelioma Settlements: National averages for mesothelioma settlements range from $1 million to $2.4 million, while trial verdicts can reach $5 million to $15 million+.
• Benzene/Leukemia Cases: These often yield high six-figure to multi-million dollar recoveries depending on the documentation of the exposure.
• Construction Accidents: Catastrophic injuries or wrongful deaths on job sites regularly lead to multi-million dollar awards, especially when OSHA violations are present.

You are entitled to compensation for your medical treatments (which for mesothelioma can exceed $1 million), your lost wages, the loss of companionship for your spouse, and the physical pain you endure every day.

As Beth B. shared in her verified review: “Ralph Manginello took his bogus case and had it dismissed within a WEEK! … A God-send law firm… I highly recommend!!” That same commitment to speed and results applies to our injury clients.

Your Path to Treatment and Justice in Colorado

Colorado is home to some of the finest medical minds in the world for treating toxic exposure diseases. Getting the right care is the first step in building the right case.

• University of Colorado Cancer Center (UCHealth): Located at the Anschutz Medical Campus in Aurora, this is Colorado’s only NCI-designated Comprehensive Cancer Center. Their thoracic oncology and leukemia programs are world-class.
• National Jewish Health (Denver): Consistently ranked as the #1 or #2 respiratory hospital in the nation. This is THE place forColorado workers with asbestosis, silicosis, and complicated occupational lung disease.
• Rocky Mountain Cancer Centers: With locations across the Front Range, they offer specialized oncology care close to home for many of our clients.

Frequently Asked Questions for Colorado Workers and Families

Can I file a claim if my Colorado employer went out of business?

Yes. Many companies that operated in Colorado, like Johns-Manville, were forced into bankruptcy by asbestos lawsuits. They were required to set up billion-dollar trust funds to pay future claims. We can still file claims against these trusts and any successor corporations that merged with your former employer.

Will filing a lawsuit affect my Colorado Workers’ Comp or VA benefits?

No. Civil litigation and trust fund claims are independent of workers’ comp and VA disability. You can receive your VA pension and still recover millions from a product manufacturer who poisoned you.

How long do I have to file a toxic exposure claim in Colorado?

Generally, Colorado has a two-year statute of limitations for personal injury. However, for “latent” diseases like mesothelioma, the Discovery Rule applies. The clock doesn’t start until you are diagnosed and realize your illness was work-related. Because every day counts, we recommend calling for a free evaluation immediately.

What evidence do I need to prove an exposure that happened 30 years ago?

We reconstruct your life. We pull Social Security earnings records, union dispatch logs, and co-worker testimonies. We have databases of which buildings in Denver used specific brands of asbestos insulation and which refineries used benzene-laden chemicals in specific years. We do the heavy lifting of proof.

What if I was a contractor and not a direct employee?

This is actually an advantage. If you were a contractor (e.g., a pipefitter for an insulation company) working at a site owned by another company (e.g., the Suncor refinery), you can sue the premises owner for failing to provide a safe site. These third-party claims are not limited by the “exclusive remedy” of workers’ comp.

The Action Colorado Families Deserve
