Authorities in Colorado have confirmed that six men died in what officials are describing as a “dairy accident” at a site in Weld County, around 30 miles north of Denver.
Emergency crews from the Southeast Weld Fire Protection District were dispatched on the evening of August 20 for a confined space rescue but instead recovered the bodies of all six victims. Fire Chief Tom Beach offered condolences, saying district personnel “recovered six deceased individuals from the space.”
According to Weld County Deputy Chief Coroner Jolene Weiner, the victims — all Hispanic males — are believed to have died from gas exposure in a confined space. Their identities are being withheld until families are notified, and autopsies will be carried out in the coming days.
The site has been identified by local media as a dairy farm. Officials confirmed that the case is not being treated as criminal. The Occupational Safety and Health Administration (OSHA) has opened an investigation to determine the cause of the incident.
Workplace accidents in confined spaces remain a recurring danger. OSHA data shows that at least 12 people died in 2024 from similar incidents, most due to chemical exposure and low oxygen. In 2025 so far, four confined-space deaths have already been reported nationwide.
Weld County, where the tragedy occurred, is a large agricultural and industrial hub with a population of around 360,000 and stretches between the Rocky Mountains and the Great Plains.
