A teacher that was using a lithium ion cell phone battery as part of an experiment, was accidentally punctured. When that happened, some smoke and foul smelling vapors were released. The Schenectady Fire Department responded after an alarm was activated.

In the story from News 10 ABC, after the affected area was ventilated, students returned to the school.
