About 20 operators who dispatch Seattle police to emergency calls had to be evacuated Monday afternoon after a potentially hazardous material was found in the 911 center. A few dispatchers remained to handle calls.
About a half-hour later, dispatchers began returning after emergency crews found nothing wrong with the air in the center.
A spokeswoman for the Fire Department said the unknown liquid was discovered on the first floor of the 911 call center. Medics treated three people on the scene for minor symptoms, including watery eyes. An ambulance took one person, with asthma, to a hospital.
A second group of firefighters checked the center, but found nothing hazardous. Nearby streets were closed for awhile. (info & photo from the Seattle Post-Intelligencer)
