The U.S. post office in Cobalt is closed today after an unusual chemical odor was discovered.
A postal worker became overwhelmed by the odor of sulfur and was taken to Middlesex Hospital.
Police spoke with a patron who described the smell as a burning plastic odor and said that person did not become ill.
The state Department of Energy and Environmental Protection responded to the scene and did not smell anything when they went through the building.
DEEP has since left the scene and said the post office remained closed at the time.
