Has the pumpkin spice craze gone too far?

A Baltimore school was evacuated Thursday after some students complained about a strange odor and said they had difficulty breathing. Fire and hazmat crews were called to investigate, and discovered the source was a pumpkin spice-scented air freshener.

WBAL-TV reports the Cristo Rey Jesuit High School was evacuated around 2:30 p.m. Thursday and a street was closed as emergency units arrived. Baltimore Fire Chief Roman Clark told the TV station that all hazardous materials tests were negative, and the scene was deemed safe.

A firefighter then discovered the source of the smell -- an aerosol plug-in -- while opening windows and installing fans.

"This plug-in air freshener that basically puts out the odor every so many seconds, and it's a pumpkin spice, and that's exactly what, if you go in there, you can smell, so it has been identified. It is not hazardous at all," Clark said.

"It was a smell that they certainly weren't used to," Bill Heiser, the school's president, told the Baltimore Sun. "At first, they thought, perhaps, it was a burned-out light bulb... It appeared to be getting stronger."

Two students and three adults to the hospital for stomach pains, according to the newspaper.

Dozens of students were also triaged at the scene.

Heiser told the Sun that he's not convinced the air freshener is to blame, but said evacuating the school was the right decision.

"I think the best thing to do, if there's any concern and you have a school of 350 students and you have 50 teachers and staff, is to be safe," Heiser said.

Classes are scheduled to resume Friday.

The school posted a statement on its website, saying students can receive counseling if needed to talk about Thursday's events.
