A Niagara County courthouse in Niagara Falls was abruptly closed Tuesday after a private contractor doing a construction project inside the building on the first floor noticed "particulate matter" had become dislodged, according to Christian W. Peck, a spokesman for Niagara County.
The particulate was tested but the initial results were inconclusive, Peck said. Out of an abundance of caution, officials decided to shut down the building.
Although a sign on the door to the building said, "Danger Asbestos," Peck said that later tests on the material indicated it was less than 1 percent asbestos. Most of it was nonhazardous vermiculite, he said.
However, the building will be closed Wednesday for a cleanup. All court cases scheduled there Wednesday will be handled at Niagara Falls City Court, 1925 Main St., court system spokesman Andrew B. Isenberg said.
The material was released when a contractor removed an old vault door on the first floor of the three-story building, which houses Niagara County Family Court and State Supreme Court.
