A Mesa Fire Department Haz-Mat Crew responded to an odor at Mesa High School, believed to be a release of pepper spray that resulted in the evacuation of the school on Thursday.
Crews responded about 2:45 p.m. to the campus’ main building at 1630 E. Southern Avenue near the end of the school day.
The odor stemmed from what appeared to be a release of pepper spray in one of the hallways on the first floor of the school, according to Forrest Smith, a Mesa fire spokesman.
A number of students who were affected by the smell were checked, but no longer complaining, according to Smith.
The Mesa Haz-Mat team is working to verify what was released and school officials worked to get the students transported home after a brief delay.
No students were taken to the hospital as a result, according to Smith.
