Colorado Springs fire crews have cleared a suspicious odor at Coronado High School.
All of the students are now back in class, after being evacuated this morning while crews search the building. The fire department tells 11News that a hazmat crew was on scene as a precaution.
School officials say members of the kitchen staff were cleaning a grease trap at the time. Crews determined that the odor was not hazardus and came from the grease trap.
No students reported any symptoms of illness.
