Authorities say a suspicious white powder found in an envelope at NASA headquarters in Washington is not hazardous.

D.C. fire department spokesman Pete Piringer says hazardous materials teams were sent about 2 p.m. Wednesday to NASA headquarters in southwest Washington after a caller reported finding an envelope with white powder.

Piringer says the caller was on the building's ninth floor and the immediate area was evacuated, but not the entire building. Threats were not received and crews determined the substance was not toxic.

Piringer say no injuries or illnesses have been reported.
