Employees at the IRS building have returned to work after an envelope containing a white powder triggered an alarm Thursday, officials said.

KCFD responded to the building at 333 W. Pershing Rd. around 2:15 p.m. to a substance alarm activated in the mail room.

According to an IRS spokesperson, it has been determined there is no threat to public safety.



The Missouri Department of Public Health lab in Jefferson City will determine the type of substance.

Besides KCFD, the FBI, IRS, U.S. Postal Inspection Service, and Department of Homeland Security Federal Protective Service were part of the response.
