Chemistry Experiment Triggers Fire Alarm at Bonney Lake High School

It was all smoke and no fire this morning at Bonney Lake High School, according to East Pierce Fire and Rescue and the Sumner School District.

Well, not even smoke, really.

Two fire engines responded to the campus after an alarm was set off in a chemistry lab.

There was no fire and appears that chemical vapors set off the sensitive classroom detector. Students had to evacuate the building while fire units cleared the scene, which was just before 10 a.m.

"It's a pretty low-level, non-incident," said communications director Ann Cook. "The detector that was triggered is pretty sensitive, due to it's location."

Students are back in class, but not without a bit of discomfort.

"There's a weird smell there now, because of what they were doing," said Cook.
