A year after six people reportedly lost their lives inhaling toxic hydrogen sulfide gas at a Colorado dairy operation, a wrongful death lawsuit has been filed on behalf of the families. For workers and their loved ones across Colorado, the case is a painful reminder that agricultural and industrial workplaces can hide invisible, lethal hazards — and that when safety systems allegedly fail, the families left behind have legal options.
This article, written by the personal injury team at Weber Law LLP, explains how these cases are typically evaluated, who may be legally responsible, and what evidence tends to matter most.
What Happened
According to reports, six workers at a Colorado dairy facility died approximately one year ago after being exposed to hydrogen sulfide (H2S) — a highly toxic gas commonly produced by decomposing organic material, including manure lagoons and confined manure storage systems frequently found on dairy operations. One year after the incident, a wrongful death lawsuit has now been filed on behalf of the deceased workers’ families.
Hydrogen sulfide is colorless, heavier than air, and at high concentrations can cause loss of consciousness and death within seconds. Precise details about the events leading to the alleged exposure — including which safety protocols were or were not in place — will likely be developed through litigation and any regulatory investigations that may be underway. For now, the essential fact is that six lives were reportedly lost in a preventable industrial exposure event, and the families are seeking accountability through the civil justice system.
Who May Be Liable
In a multi-fatality toxic exposure case like this one, liability is rarely limited to a single party. Based on the general facts as reported, several categories of defendants could be named or added as discovery unfolds:
- The dairy operator or owning entity. As the operator of the premises and the employer of the affected workers, the business may be liable for allegedly failing to provide a safe workplace, failing to train workers on confined-space and gas hazards, and failing to install or maintain gas monitoring and ventilation systems.
- Parent companies, management companies, or affiliated entities. Complex agricultural operations often involve layered corporate ownership. Any entity that exercised control over safety policies could be a defendant.
- Contractors and subcontractors. If outside firms were performing maintenance, pumping, agitation, or cleaning of manure storage at the time of the alleged incident, they may share responsibility.
- Equipment manufacturers. If a pump, agitator, gas detector, ventilation system, or personal protective equipment allegedly failed or lacked adequate warnings, a product liability claim may be viable.
- Engineers or design professionals. Anyone who designed the facility’s manure handling or ventilation systems could potentially be liable if the design allegedly created an unreasonable risk.
Because Colorado’s workers’ compensation system generally limits direct claims against an employer, third-party liability — claims against non-employer defendants — often becomes central in these cases.
Legal Theories That May Apply
Several overlapping legal theories may support the families’ claims:
- Wrongful death. Colorado’s Wrongful Death Act allows certain surviving family members to recover when a death is caused by another party’s alleged negligence or wrongful act.
- Negligence. The core theory: defendants owed a duty of reasonable care, allegedly breached it, and that breach caused the deaths.
- Premises liability. Property owners and operators can be liable for dangerous conditions on their property that allegedly cause harm to those lawfully present.
- Negligence per se. If defendants allegedly violated OSHA standards, confined-space regulations, or other safety statutes, that violation can help establish negligence.
- Product liability. If safety equipment or facility components allegedly failed, manufacturers may face design defect, manufacturing defect, or failure-to-warn claims.
- Survival actions. Claims that belong to the estate for the decedent’s own suffering and losses before death, brought alongside the wrongful death claim.
Damages Victims May Recover
Compensable losses in a Colorado wrongful death or toxic exposure case typically include:
- Economic damages: lost future earnings and financial support, lost household services, medical bills incurred before death, and funeral and burial expenses.
- Non-economic damages: grief, loss of companionship, emotional pain and suffering endured by surviving family. Colorado caps non-economic damages in wrongful death cases by statute, though the caps are periodically adjusted and certain exceptions may apply.
- Loss of consortium for spouses, and loss of parental guidance for children.
- Punitive (exemplary) damages where a defendant’s conduct is alleged to have been willful, wanton, or fraudulent. Colorado limits exemplary damages and requires specific pleading procedures.
- Survival damages for pre-death suffering and losses, brought by the estate.
Every case is different, and the ultimate value depends on liability strength, the decedents’ ages and earnings, family structure, and the quality of proof.
Evidence That Strengthens a Case
Toxic gas exposure cases are highly technical. The strongest cases are typically built from a combination of:
- OSHA and CDPHE investigation files, including citations, interview transcripts, and photographs.
- Air monitoring data and any records of gas detector readings, maintenance logs, and calibration records.
- Facility design plans, ventilation specifications, and manure handling protocols.
- Training records — or the absence of them — for confined space entry, H2S awareness, and emergency response.
- Witness statements from co-workers, first responders, and rescuers.
- Autopsy and toxicology reports confirming cause of death.
- Manufacturer documentation for pumps, agitators, detectors, and PPE.
- Expert reports from industrial hygienists, agricultural safety engineers, and toxicologists.
- Internal communications — emails, texts, safety meeting minutes — that may show prior warnings about the alleged hazard.
Evidence preservation matters enormously. Facilities can be cleaned, equipment replaced, and records lost. Sending a formal preservation letter early is often critical.
What to Do Next
If you lost a family member — or were seriously injured — in an industrial exposure, workplace explosion, agricultural incident, or any similar event in Colorado, consider taking these steps:
- Preserve everything. Keep pay stubs, employment records, safety documents, photos, and any communications about workplace conditions.
- Request the OSHA and agency files. Public records requests can start early.
- Document your family’s losses. Financial records, memories, and impact statements all matter.
- Do not give recorded statements to insurers or defense representatives without first consulting a lawyer.
- Watch the clock. Colorado’s statute of limitations for wrongful death is generally two years from the date of death, but exceptions and shorter deadlines can apply — especially for claims against governmental entities.

Frequently Asked Questions
Can I sue if my family member died at work in Colorado?
In many cases, yes — but not always against the employer directly. Colorado workers’ compensation generally bars lawsuits against employers, but claims against third parties such as contractors, equipment manufacturers, and property owners may still be viable. An attorney can evaluate which theories apply to your situation.
How long do I have to file a wrongful death lawsuit in Colorado?
Colorado’s wrongful death statute of limitations is generally two years from the date of death. Claims against governmental entities may require formal notice within just 182 days, and product liability or other theories can carry different deadlines. Talking to a lawyer quickly protects your rights.
Who can bring a wrongful death claim in Colorado?
Colorado law creates a tiered system: in the first year after death, only a surviving spouse (or heirs with the spouse’s consent) may sue. After the first year, children and, in some circumstances, parents may bring claims. The rules are technical, so early legal advice is important.
What is hydrogen sulfide and why is it so dangerous?
Hydrogen sulfide (H2S) is a toxic gas commonly generated by decomposing organic matter, including manure. At low levels it smells like rotten eggs, but at higher concentrations it deadens the sense of smell and can cause rapid unconsciousness or death. It is a well-known hazard in dairy, agricultural, oil and gas, and wastewater environments.
What if the workers were undocumented — can families still recover?
Yes. Under Colorado law, immigration status generally does not bar a family from pursuing wrongful death or personal injury claims. Damages calculations can raise complex issues, but families should not assume they have no rights.
Does workers’ compensation prevent me from filing a lawsuit?
Workers’ comp typically prevents suing the direct employer, but it does not block claims against third parties allegedly responsible for the harm — such as equipment manufacturers, contractors, or negligent property owners. Many serious workplace injury cases involve both a comp claim and a separate civil lawsuit.
How much does it cost to hire a personal injury lawyer?
Most personal injury and wrongful death attorneys, including Weber Law LLP, work on a contingency fee basis. That means you pay nothing up front, and the firm is only paid if it recovers compensation for you. Initial consultations are typically free.
What damages are available in a Colorado wrongful death case?
Families may recover economic losses such as lost financial support and funeral expenses, and non-economic losses such as grief and loss of companionship. Punitive damages may be available where the defendant’s conduct is alleged to be willful or wanton. Colorado caps certain non-economic damages by statute.
