BROWNSBURG, Ind. — The Brownsburg Fire Department said more than 5,000 pounds of liquid anhydrous ammonia leaked at Weston Foods, a bakery located on Maplehurst Drive.

Seven people ended up being transported to local hospitals due to the leak, authorities later said, all reported to be in stable condition.

The fire department said the leak occurred inside the bakery on Thursday afternoon. Workers had to be evacuated with many reportedly overcome by the fumes. Workers reported experiencing headaches and shortness of breath.

At first, the workers were sheltered in place at hotels and attended to at the scene by paramedics. Seven were ultimately taken to a hospital, however.

Hazmat was called to the scene to investigate the source of the leak along with decontaminating any affected areas.

According to fire officials, the ammonia cloud “dissipated pretty quickly.”
