UPDATE 4:45PM: New information has been released by Marshfield Fire & Rescue in regards to the HAZMAT incident at Marshfield Clinic.

Deputy Chief Troy Weiland says their crews were called at approximately 1:27pm Monday for a spill of Nitric acid.

According to Weiland, lab employees at the Melvin Laird Center on the Clinic Campus were pouring some of the acid into a 1 liter container when an unexpected chemical reaction occurred, causing a flush of orange-colored gas.

Two floors of the building were evacuated and all employees were accounted for after HAZMAT and Fire/Rescue crews arrived.

The interior atmosphere was ventilated, checked and cleared by crews.

The spilled acid was taken away and crews cleared the scene at approximately 2:57pm.
