Two men went to a Maryland hospital after opening a package they believed contained a some type of chemical, authorities said.
The men opened the package at their home on Military Road and said they felt "different and tingly," according to Frederick Police Lt. Clark Pennington. The men took the package with them to Frederick Memorial Hospital.
They were decontaminated and treated at the hospital. Their injuries were not serious.
Authorities believe the substance was a common household item. It will be tested at a lab.
The hospital diverted ambulances and stopped accepting new patients in the emergency room, but hospital operations otherwise carried on normally, officials said.
Other patients in the emergency room were moved to an area away from the two men.
The Frederick fire and police departments are investigating at the hospital and in the neighborhood where the package was sent.
