Seattle Fire Fighters responded to the Ballard Library on the morning of June 20 after a librarian collecting books from the book drop box burned her finger on an unknown, sticky white powder.

Seattle Fire Department Public Information Officer Lt. Harold Webb said the librarian reported that her fingers starting "tingling."

The victim washed her hands immediately after coming in to contact the substance. She was examined by paramedics who determined she wasn't in any immediate danger. She did not report any further symptoms or reactions, but said she would go to Northwest Hospital for follow up.

The Seattle Fire Department Hazmat (hazardous materials) unit was called to the scene and cordoned off an area surrounding the library, the Neighborhood Service Center and Bartell Drugs.

Fire Fighters in Hazmat suits went inside the library but could not locate any of the hazardous materials. They also placed probes in the book drop boxes in front of library and the drop box at the Neighborhood Service Center before declaring the building safe to enter.

Seattle Public Library spokesperson Andra Addison said maintenance staff came and cleaned out the book drops "spic and span," after the incident.

"It's good news that everyone is fine and the library reopened. The staff followed proper procedure," said Addison.

The entire response took two hours. The first call to 911 was made at 10:33 a.m.
