Precautionary Evacuation Today

Good morning Sierra Parents and Staff,Today at about 8:38 AM, a fire alarm was triggered in our Robotics lab, which had no students at the time. Out of an abundance of caution, Sierra evacuated all students onto the field and had fire department dispatched to inspect the lab. All students safely were evacuated to our field and the Orange County Fire inspected classrooms and cleared the school for all students to return to their classrooms. Our District team is working on the minor repair to an AC unit that triggered the fire alarm. Should you have any questions, please call us at 714-567-3500.
