Sevierville Public Information Officer Bob Stahlke said emergency personnel responded to a reported explosion at Johnson Matthew Catalysts around 1 p.m. Thursday.

Residents and businesses within 1,000 feet of the building were advised to shelter in place . A voluntary evacuation of the same area was issued over concerns that a secondary explosion was possible.

Stahlke said that no one decided to evacuate. The shelter-in-place order and voluntary evacuation were rescinded later in the afternoon. No injuries have been reported.

Johnson Matthey officials said a nickel aluminum powder likely exploded and the fire was contained by their fire suppression system. Firefighters entered the buildings and extinguished any remaining hot spots.
