A farmer and 16 of his cattle died in a freak accident after a "deadly dome of air" formed in a Wisconsin farm's manure holding tank.
Michael Biadasz, a 29-year-old farmer from Amherst, Wisconsin, died of gas poisoning on his family's farm after being overcome by fumes of either methane or sulfur oxide, according to WAOW. Initially, 13 of the farm's cattle died, as well; later, three more expired, bringing the total cattle deaths to 16.
Bob Biadasz, the 29-year old's father and co-owner of Biadasz Farms, said the tragedy was the result of a "perfect storm" of unusual and unexpected weather conditions. When the tank was prepped to be pumped, warm upper air temperatures trapped the gases in a dome of air, which then poisoned Michael and the cattle.
Biadasz was found dead when other workers arrived to begin hauling manure away from the tank.
"The family is devastated, absolutely devastated," Portage County Coroner Scott Rifleman told WAOW.
Rifleman told WSAW that gas poisoning deaths typically occur in closed areas, making the incident even more surprising. The coroner said atmospheric pressure prevented the gases from dissipating.
The coroner went on to say that an investigation is underway to determine exactly what caused Biadasz's death. According to Rifleman, Biadasz had safely emptied the same tank hundreds of times prior to the fatal incident.
The Biadasz family honored Michael by parking a line of tractors and machinery along the road that passes the farm. Among the vehicles parked were a blue tractor, several red trucks and Michael's black pickup truck.
"As if there isn't already enough danger in the lives of farmers, this family had to suffer this freak accident," one Facebook user commented on the story, according to All That's News. "So sad."
Following the tragic accident, many are calling for tougher regulations to be placed on manure holding tanks to prevent a similar incident in the future. The National Agriculture Safety Database says there should be proper ventilation in areas where animals are stored and that warning signs must be posted nearby, according to All That's News.
"In addition to adhering to proper construction and maintenance procedures for liquid manure storage facilities, owners should be encouraged to follow a few precautionary measures to protect both workers and livestock from harmful manure gases," the NASD writes.
A similar unfortunate fate befell a Virginia family in 2007, when five of its members died as a result of a pipe blockage that caused a fatal buildup of methane gas, WASW reports.
