Original post (11:44 a.m.): The Austin Fire Department says five kids and three adults are being treated in a Hazmat situation at Burnet Middle School in Northwest Austin. The Austin Independent School District says the cause appears to be some sort of chemical substance found in a student restroom.
The patients report burning eyes and nausea. Some have been transported to Dell Children’s Hospital.
The entire school was evacuated for about 20 minutes. While everyone has now been allowed back inside, emergency officials are blocking off the area where the substance was found.
KUT News has a reporter on the scene and are working to get more information.
