UPDATE AT 1:03 P.M.: Seattle Fire Department says the white powder was not hazardous.
ORIGINAL POST: The Seattle Fire Department’s Hazardous Materials team is investigating an envelope containing a suspicious white powder that was sent to an office building at 1215 Fourth Ave. in downtown Seattle.
Someone inside the office called 911 shortly after 11 a.m., said fire department spokesman Kyle Moore. The Seattle Police Department’s Arson and Bomb Team also responded, he said.
Fire officials have evacuated the 20th and 21st floors of the building, Moore said. Twenty-five people who were in the general area when the envelope was opened have been quarantined in a conference room, but none are showing any symptoms of exposure to a dangerous substance, he said.
The envelope containing the suspicious powder was placed inside a mail-room closet until the Haz-Mat team, which entered the building around 12:15 p.m., can do basic field-tests to determine if the substance is dangerous or innocuous, Moore said.
