A small cement mixer that was once used to separate cement from flooring has been found to have been a source of contamination in an Indiana home.
The Indiana State Police say the metal dust-collecting device was found in a home in rural Indiana on Tuesday.
Police say it was placed inside the cement mixer and was removed by a home maintenance worker.
It was then put back in place, and the dust collector was returned to the home.
The metal dust was then removed by the maintenance worker again.
The State Police said there is no evidence of anyone being exposed to the metal powder and no cases of exposure to the dust were found.
