The Jackson Fire Department was called to the U.S. Post Office on Cedar Park Court at 12:54 p.m. Thursday after employees complained of headaches and a chemical odor.
West Bend HazMat, Milwaukee HazMat, Wisconsin State Patrol, U.S. Postal Inspection Service, and North Shore Environmental all responded to the scene.
“We did tests and found some readings but couldn’t determine what it was,” said Jackson Fire Chief Aaron Swaney in a one-on-one conversation.
Swaney said there was a “recognizable smell” when you entered the building. “We took precautions and used protective equipment to make sure we were safe as well,” he said. “It was determined the odor did not come from any package or mailing.”
Evidence has been submitted to the State Health Department in Madison to be analyzed. The Post Office closed early. The chief said one received any medical treatment for their symptoms.
The U.S. Post Office in Jackson will be closed on Friday. More information on the cause of the odor is expected to be released on Friday.
