Students were displaced when a false fire alarm interrupted classes on Oct. 29.

The alarm rang out at approximately 2:30 p.m., resulting in students evacuating from buildings 7 and 8.

“Usually when it’s a false alarm, it’s something faulty or someone pulled a station,” San Bruno Firefighter, Holly Nelson said. “We haven’t really determined the cause, but we believe it’s something electrical.”

“[Students] did a good job self evacuating,” Nick Chavez of Facilities said.

One group of students decided to use the extra time to study for their upcoming chemistry test.

“It starts in nine minutes,” student Laura Ziganti said. “We’re keeping our fingers crossed that the test gets cancelled.”
