The last day of classes brought some extra excitement to a south Kitchener school.

Firefighters were called to J.W. Gerth Public School on Apple Ridge Drive around 3 p.m. Thursday after a fire forced everybody out of the school.

“There’s been a malfunction in the electrical box causing some small fire,” Kitchener Fire Department deputy chief Gary Mann told CTV News.

The fire was quickly extinguished before spreading past the electrical room, but smoke filled the school’s hallways.

Mann says the evacuation of the building was a straightforward, orderly process – helped, perhaps, by a fire drill the school had conducted earlier in the day.

“They were finely tuned for their evacuation this afternoon,” he said.

Waterloo Region District School Board officials say arrangements will be made for students to pick up any belongings they may have left inside the school.

No injuries were reported.
