Seattle Fire Department’s hazardous-materials team was called out to The Seattle Times about 12:30 p.m. today after another suspicious envelope containing an unidentified substance was found in the mail.
Dana Vander Houwen, fire-department spokeswoman, said one employee has been isolated for possible exposure to contaminants. He was alone in the mailroom when he found the envelope, but didn’t open it. The letter was addressed only to The Seattle Times.
Vander Houwen said firefighters in hazmat suits were going into the mailroom to assess whether the envelope posed any risk.
