Old peppermint oil in the basement of Paterson's School 10 caused an evacuation and sent a teacher to the hospital Thursday morning.

Students and staff were moved to school 18 after someone smelled a "suspicious odor" and a teacher became light-headed, said Jerry Speziale, Paterson's public safety director. Peppermint oil is used for cleaning and as a dietary supplement.

Fire Chief Brian McDermott said the oil was old.

The teacher was taken to St. Joseph's University Medical Center with non-life threatening injuries.

The Paterson Fire Department went into the basement and tested the levels and found no noxious gases or increase in carbon monoxide, Speziale said. Firefighters were planning to ventilate the building and turn the heat on before the students and staff were allowed to come back. They also planned to retest the levels.

A robocall was sent by the school district to the parents of School 10 to inform them of what happened.

The Passaic County Sheriff's Office, Paterson Fire Department and Paterson Police Department were on the scene.
