Date(s) of Assessment: May 15 and 16, 2019
An ABC fire extinguisher (dry chemical) was discharged, primarily impacting one classroom and the central portion of a pod.
The Office of the Environment responded to the scene shortly after it was reported.
The Heating Ventilation and Air Conditioning (HVAC) Department was contacted and the HVAC system was shut down to prevent the spread of the discharged material.
A board-approved contractor was contacted to perform the clean-up. The area was contained and the ventilation system was sealed.
The areas were cleaned with a vacuum equipped with a High Efficiency Particulate Air (HEPA) air filter and then wiped with a special cloth to pick up any remaining residue.
Air Scrubbers equipped with HEPA filters were operated while work was being conducted.
The area was visually cleared by the Office of the Environment the morning of May 16, 2019, prior to school starting.
