Wyoming Toxic Exposure & Dangerous Industry Injury Lawyers: Fighting for the Workers Who Built the Equality State

You didn’t know. For twenty years, thirty years, maybe longer—you went to work in Wyoming’s mines, refineries, and railyards, did your job, and came home to your family in Casper, Cheyenne, or Gillette. Nobody told you the dust you breathed at the Jim Bridger Power Plant, the chemicals you handled at the Sinclair Refinery, or the insulation you cut while building Wyoming’s infrastructure would one day try to kill you. Now you know. And now you have rights.

At Attorney 911, we recognize that your diagnosis of mesothelioma, leukemia, or silicosis is not just a medical statistic—it is a betrayal. The companies that profited from your labor in Wyoming knew their products were lethal. They had the studies. They had the data. They suppressed it. While you were building Wyoming’s energy independence, they were protecting their bottom line at the cost of your life.

We are not just another law firm. Led by Ralph Manginello, a trial veteran with over 27 years of experience who was part of the litigation team for the BP Texas City Refinery explosion—a $2.1 billion total case—and backed by Lupe Peña, a former insurance defense insider, our team brings a nuclear level of aggression to corporate defendants. We know Wyoming’s industrial corridors, from the Powder River Basin to the refinery rows of Natrona and Laramie Counties. We know the employers, we know the exposure sites, and we know how the defense will try to fight you. Call us now at 1-888-ATTY-911. Your consultation is free, and we take no fee unless we win your case.

The Insider Advantage: Why Wyoming Workers Choose Attorney 911

When you take on a multi-billion dollar corporation like Union Pacific, ExxonMobil, or HF Sinclair, you are entering a war. These companies have spent the last 50 years building a massive defense infrastructure designed to delay, deny, and minimize your suffering. To beat them, you need an attorney who has seen their playbook from the inside.

Our associate attorney, Lupe Peña, is that advantage. Before joining us to fight for the people of Wyoming, Lupe worked on the defense side. He was inside the machine, evaluating toxic exposure and industrial injury claims for the very corporations and insurance companies we now sue. He knows exactly how they attempt to hide evidence, how they use “junk science” to discredit your diagnosis, and how they exploit legal loopholes to avoid paying what they owe.

Ralph Manginello brings nearly three decades of high-stakes litigation experience to your case. Admitted to the U.S. District Court for the Southern District of Texas and the State Bar of Texas, Ralph has recovered millions for injured workers. His experience in the BP Texas City litigation proves he doesn’t blink when facing the world’s largest oil companies. We don’t refer your case out; we litigate it. When you call 1-888-ATTY-911, you are getting a team ready for federal court.

Wyoming Industrial History: A Legacy of Exposure

Wyoming’s economic strength is built on mining and energy, but that strength came with a hidden cost. For decades, workers across the state were exposed to substances that we now know cause catastrophic, latent-onset diseases.

The Power Plants and Refineries of Casper and Cheyenne

Whether you worked at the Sinclair Wyoming Refining Company (now HF Sinclair), the Dave Johnston Power Plant, or the Laramie River Station, you were surrounded by hazards. Asbestos was used in virtually every high-heat application—pipe lagging, boiler insulation, and gaskets. Refineries also introduced benzene, a known carcinogen, into the daily environment of every operator and maintenance worker in the Casper and Cheyenne corridors.

The Powder River Basin and Wyoming Mining

The coal mines of the Powder River Basin and the trona mines in Sweetwater County created massive amounts of crystalline silica dust. When you cut through Wyoming’s earth, you aren’t just moving dirt; you are releasing microscopic particles that cause irreversible lung scarring. Furthermore, Wyoming’s history as a uranium mining hub (Gas Hills, Shirley Basin) has left a legacy of radiation-induced cancers that many miners are only now discovering.

The Railroad Corridors

Wyoming is the heart of the American railroad. Workers for Union Pacific and BNSF in Laramie, Rawlins, and Green River handled asbestos-containing brake shoes and breathed in diesel exhaust for 40-hour shifts, year after year. These exposures create synergistic risks that railroads spent decades ignoring.

If you worked in these industries and are now sick, the law provides a pathway to justice. But the clock is running. Evidence is disappearing as sites are decommissioned and records are destroyed. Call Attorney 911 at 1-888-ATTY-911 to preserve your rights today.

Mesothelioma and Asbestos Exposure: The Anchor of Justice

Asbestos fibers are microscopic, but their impact on the human body is devastating. In Wyoming, asbestos exposure was not accidental—it was an atmospheric constant in industrial workplaces for most of the 20th century.

The Biological Mechanism of Mesothelioma

Asbestos fibers measuring five micrometers or longer lodge in the mesothelial lining of your lungs (pleura) or abdomen (peritoneum) and stay there—permanently. Your body’s macrophages, the white blood cells responsible for cleaning foreign particles, attempt a process called “frustrated phagocytosis.” Because the fibers are too long and sharp, the macrophages die while trying to engulf them, releasing chronic inflammatory cytokines and reactive oxygen species (ROS).

Over a latency period of 20 to 50 years, this constant state of inflammation causes oxidative DNA damage. Specifically, it can inactivate the BAP1 and p16 tumor suppressor genes, which are the biological “brakes” on cell growth. Once these brakes are removed, mesothelial cells undergo malignant transformation into mesothelioma.

Symptom Recognition Triggers

Many Wyoming residents misdiagnose their early mesothelioma symptoms as the “Wyoming flu” or signs of aging. If you worked in Wyoming’s industrial sectors and notice the following, you must seek a specialist:

• Pleural Mesothelioma: Persistent dry cough, chest pain that worsens with a deep breath, shortness of breath even when resting, and unexplained weight loss.
• Peritoneal Mesothelioma: Severe abdominal swelling (ascites), nausea, and bowel changes.

The Wyoming Asbestos Defendant Roster

We investigate claims against the companies that manufactured and supplied the asbestos products used at Wyoming worksites. This includes:

• Johns-Manville: The world’s largest asbestos producer, whose products were used in Power River Basin coal facilities.
• Owens Corning: Manufacturers of Kaylo pipe insulation, standard in Casper refineries.
• W.R. Grace: Whose vermiculite (Zonolite) was shipped across Wyoming and was often contaminated with tremolite asbestos.

If you have been diagnosed, you may qualify for compensation from over 60 active asbestos bankruptcy trusts currently holding approximately $30 billion in assets. However, these trusts are depleting. The Manville Trust, for example, currently pays only about 5% of approved claim values. Every year you wait, the percentage can drop. Call (888) 288-9911 now to secure your share of the recovery you earned.

Nuclear and Radiation Exposure: Wyoming’s Uranium Legacy

Wyoming was the epicenter of the American uranium boom. From the Gas Hills in Fremont County to the Shirley Basin and the Powder River Basin, thousands of Wyomingites moved the radioactive fuel for our nation’s nuclear program.

RECA: The Radiation Exposure Compensation Act

In 2024 and 2025, the federal government expanded RECA, recognizing that uranium miners, millers, and ore transporters in Wyoming were poisoned by the very materials they were told were safe. If you worked in Wyoming uranium mining before 1990 and have since been diagnosed with lung cancer, renal cancer, or non-malignant respiratory diseases like pulmonary fibrosis, you may be entitled to a $100,000 to $150,000 lump-sum payment from the Department of Justice.

How Radiation Causes Cancer

Ionizing radiation (alpha and beta particles) directly damages the molecular structure of your DNA. Alpha particles, which are inhaled as radon decay products in Wyoming’s underground and open-pit mines, have high linear energy transfer (LET). They create double-strand DNA breaks that are difficult for cells to repair accurately. When the cell repairs these breaks incorrectly, it leads to chromosomal rearrangements and translocations that trigger leukemia (AML) and solid tumors.

Because we understand the science of RECA and the EEOICPA (Energy Employees Occupational Illness Compensation Program Act), we help Wyoming families navigate the complex federal bureaucracy. Your country poisoned you while you were serving its energy needs. We are here to make it right. Call 1-888-ATTY-911 for a free evaluation of your RECA eligibility.

Silicosis and Mining Injuries: The Dust of the Basin

Wyoming is the nation’s leading coal producer. But the coal dust and crystalline silica found in the Powder River Basin and at Wyoming’s fracking sites are silent killers.

The Mechanism of Silicosis

Crystalline silica is 100 times smaller than a grain of sand. When inhaled, these particles reach the alveolar sacs of the lungs. The body recognizes these sharp, indestructible crystals as invaders. Microscopic scars (fibrosis) form around each particle. This scarring is progressive—even after you stop working in the mine, the scars continue to grow, eventually turning your lung tissue into something resembling leather.

Progressive vs. Accelerated Silicosis

In Wyoming’s modern oilfield fracking operations, we are seeing a spike in “accelerated silicosis.” Workers cutting quartz or handling sand are developing fatal lung disease in as little as five to ten years. This is not just a workplace hazard; it is a failure of employers to provide adequate respiratory protection and dust suppression.

Ralph Manginello and his team hold mining companies and equipment manufacturers accountable for these failures. Under Wyoming law, you may have a third-party claim against the manufacturer of the sand or the safety equipment (masks and respirators) that failed to protect you. These claims allow for compensation far exceeding the limited benefits of workers’ comp.

Benzene and Industrial Chemical Exposure at Wyoming Refineries

If you worked at a refinery in Casper, Cheyenne, or Sinclair, you were likely exposed to benzene—a colorless, sweet-smelling chemical that is a natural component of crude oil.

Benzene and the Bone Marrow

Benzene does not just make you sick; it rewrites your blood at the molecular level. Your liver metabolizes benzene into a dangerous compound called muconaldehyde. This metabolite travels to your bone marrow, where it attacks hematopoietic stem cells. The result is a total disruption of blood cell production, leading to:

• Acute Myeloid Leukemia (AML): An aggressive blood cancer.
• Myelodysplastic Syndrome (MDS): Often called “pre-leukemia.”
• Aplastic Anemia: Where the marrow stops producing blood altogether.

The 1987 Standard Betrayal

OSHA did not lower the permissible exposure limit (PEL) for benzene to 1 ppm until 1987. For decades before that, Wyoming refinery operators were legally allowed to expose you to 10 ppm—a level now known to be 10 times higher than “safe.” The companies knew 10 ppm was dangerous long before the government acted.

With Lupe Peña’s insider knowledge of how refinery insurance companies value these claims, we build a wall-to-wall case against the chemical manufacturers and refinery operators. If you were an operator, lab tech, or pipefitter in Natrona or Laramie County, call 1-888-ATTY-911. We speak the language of the refinery, and we know how to prove your exposure.

FELA: Protecting Wyoming’s Railroad Workers

Wyoming is the heart of the Union Pacific (UP) and BNSF networks. But the railroad industry has a long history of ignoring worker safety in the pursuit of efficiency.

FELA vs. Workers’ Comp

If you are a railroad worker, you are NOT covered by Wyoming workers’ compensation. Instead, you are protected by the Federal Employers Liability Act (FELA). Under FELA, you have the right to a JURY TRIAL against the railroad. You can recover for pain and suffering, mental anguish, and full lost wages—damages that are capped or prohibited in standard workers’ comp.

The Lower Burden of Proof

FELA is a “featherweight” burden of proof statute. You only need to prove that the railroad’s negligence played ANY part, however small, in causing your injury or toxic exposure.

• Asbestos in Locomotives: If you were a machinist or shop worker in Rawlins or Cheyenne, you handled asbestos-containing gaskets and brake shoes daily.
• Diesel Exhaust: Long-term inhalation of diesel particulate matter is a documented cause of lung and bladder cancer.

The railroads have a “company doctor” system designed to get you back to work before your injuries are stabilized. Don’t fall for it. Talk to a lawyer who knows the railroad playbook. Call Attorney 911 at (888) 288-9911.

Construction, Scaffolds, and Crane Collapses in Wyoming

As Wyoming cities grow, construction accidents are on the rise. Whether it’s a fall from a scaffold at a Cheyenne job site or a crane collapse at an infrastructure project, these are almost always preventable.

Third-Party Liability: The Parallel Path to Recovery

Your employer will tell you that workers’ comp is all you can get. They aren’t telling you about the third-party claim. If your fall was caused by a defective scaffold made by another company, or if a subcontractor’s negligence led to your injury, you can sue that third party for millions.

• Scaffold Falls: OSHA 29 CFR 1926 Subpart M requires fall protection for any worker six feet or higher.
• Trench Collapses: One cubic yard of Wyoming soil weighs 3,000 pounds—as much as a car. If that trench wasn’t shored or sloped per OSHA Subpart P, your employer broke federal law.

We move fast to preserve evidence at Wyoming construction sites before the contractor can “clean up” the scene. Ralph Manginello personally oversees the investigation of these catastrophic sites.

Multiple Compensation Pathways: Maximizing Your Wyoming Claim

Most law firms in Wyoming only look at one source of recovery. At Attorney 911, we pursue the Full Recovery Stack. For a single client, we may simultaneously file:

1. Trust Fund Claims: Identifying every bankrupt manufacturer whose products poisoned you.
2. Solvent Lawsuits: Suing the current, active corporations responsible for your exposure.
3. Workers’ Compensation: Securing your immediate medical benefits.
4. VA Disability: For veterans exposed to asbestos or Camp Lejeune water during service.
5. Wrongful Death / Survival Actions: If you have lost a loved one, we fight for the family’s future.

“Other firms leave money on the table because they don’t know all the tables exist. We do.” In December 2025, a jury awarded $1.5 billion in a single mesothelioma case against Johnson & Johnson. In 2024, ExxonMobil was hit with a $725 million benzene verdict. The money is real, but the corporations will not hand it over without a fight.

Counter-Intelligence: How We Stop the Defense Playbook

Because Lupe Peña worked for the other side, we know exactly what tricks the defense will try in your Wyoming case:

• “The Lifestyle Defense”: They will try to blame your diagnosis on smoking or genetics. We use medical experts from institutions like MD Anderson to prove that mesothelioma and benzene-related AML have specific environmental triggers that lifestyle factors cannot explain.
• “The Identification Trap”: They will demand you name the exact brand of insulation you used in 1974. We have massive product databases and co-worker witness networks to identify those brands for you.
• “The Terminal Delay”: They know mesothelioma patients have a short prognosis. They will try to delay your case, hoping you pass away before trial. We file for expedited trial dockets and take your deposition immediately to ensure your story is told and your family is protected.

Wyoming Resources: Where to Go for Help

If you or a loved one are facing a diagnosis, you are not alone. There are world-class resources available to Wyoming residents:

Medical Treatment

• MD Anderson Cancer Center (Houston, TX): Ranked #1 in the nation. It is a flight away, but their mesothelioma and leukemia programs are the best in the world. We can help you navigate getting there.
• University of Colorado Cancer Center (Aurora, CO): The nearest NCI-designated cancer center for many Wyoming residents.
• VA Medical Centers: Veterans in Wyoming can access toxic exposure screenings at the Cheyenne VAMC, the Sheridan VAMC, and the Casper VA Clinic. Under the PACT Act, these screenings are free.

Support Organizations

• Mesothelioma Applied Research Foundation: Provides peer mentoring and clinical trial matching.
• Leukemia & Lymphoma Society: Offers financial assistance and information specialists for AML and MDS patients.
• Radiation Exposure Compensation Program (DOJ): The official portal for Wyoming uranium miners to file RECA claims.

FAQ: Your Wyoming Toxic Exposure Questions Answered

I was exposed 30 years ago. Is it too late to sue in Wyoming?

No. Wyoming and federal law follow the Discovery Rule. The statute of limitations typically doesn’t start until you are diagnosed or discover that your illness was caused by the exposure. For someone diagnosed with mesothelioma today from exposure in a 1970s mine, the clock is just starting now.

How much does a Wyoming toxic exposure lawyer cost?

At Attorney 911, we work on a contingency fee basis. You pay zero dollars upfront. We advance all costs for medical experts, industrial hygienists, and court filings. If we don’t win your case, you owe us nothing.

Can I file a claim if my former employer is out of business?

Yes. We specialize in identifying successor corporations and bankruptcy trusts. Over 60 companies that operated in or shipped products to Wyoming have established trust funds specifically to pay workers like you after the company closed.

Will this affect my Social Security or VA benefits?

No. Civil litigation or trust fund claims are independent of your government benefits. Pursuing a settlement against a corporation for poisoning you does not stop you from receiving VA disability or Social Security.

Is workers’ comp my only option for a construction injury?

Almost never. If a third party—like an equipment manufacturer, a general contractor, or a property owner—contributed to the dangerous condition, you can file a third-party lawsuit. These lawsuits represent the majority of the compensation recovered in serious accident cases.

My husband died of mesothelioma. Can I still file a claim?

Yes. You may have a Wrongful Death claim for the loss of companionship and financial support, and a Survival Action for the pain and suffering your husband endured. We represent the estates of many Wyoming workers who were taken too soon.
