WESTON – The cafeteria at Cyprus Bay High School in Weston was evacuated around 9:30 a.m. Friday morning due to a suspected Carbon monoxide Gas leak.

The City of Weston posted on X (formerly Twitter) that the Broward Sheriff’s Fire Department “was called to Cypress Bay High School where three people who became dizzy in the cafeteria were transported to a nearby hospital.”

The three people were taken to the nearby Cleveland Clinic Hospital. All were adults and two were school employees.

“There were no students in the cafeteria at the time. The hazardous materials were requested and that was done. They determined there was a carbon monoxide leak in or near the cafeteria. Out of an abundance of caution, the entire gas line system to the school was shut off,” said Broward Fire Rescue Battalion Chief Michael Kane

Only Building 1 was evacuated and students were moved to Building 300. Two hazardous materials teams ventilated the building and carbon monoxide levels dropped to low levels.

“Other adult patients are being evaluated and additional emergency units have been called,” the city said in an update. “The school is taking all necessary safety precautions.”

A total of five people were treated at the scene, including four school employees and a firefighter. All patients were transported to Cleveland Clinic Hospital.

According to John Sullivan of the Broward County School District, all students are safe. Parents who wish to pick up their children can leave school early.

Falcon Cove Middle School on the same campus was not affected.

The source of the carbon monoxide leak is being investigated.

Cypress Bay High School is the largest high school in the state with approximately 4,800 students.

Carbon monoxide is an invisible, odorless and tasteless gas and is highly toxic. Depending on the level of exposure, CO can cause fatigue, weakness, chest pain in people with heart disease, nausea, vomiting, headaches, confusion, visual disturbances, unconsciousness and, in severe cases, death.
