Multiple people at Sacred Heart School in Coronado reported feeling faint Wednesday afternoon, triggering a response from Coronado's police and fire departments.
The sicknesses began at about 1 p.m. Wednesday at the school and church on 706 C St., according to police.
Shortly after police and fire crews responded, the students were evacuated to Spreckles Park. They later moved into Sacred Heart Catholic Church while early release was coordinated.
Parents were asked to wait at the park as police and firefighters investigated the cause.
Three teachers reported the sickness, one in the morning and two in the afternoon. Those teachers were treated by police and fire authorities, according to Michael Lawton with the Coronado Police Department.
The first teacher is fine now, Lawton added.
A sewer-like smell was reported in the morning at the school and in the courtyard. City officials inspected the area, but said everything looked fine, Lawton said.
Local
Coronado's police chief said authorities don't believe there is anything hazardous at the school, but they evacuated the school and called a HAZMAT team to be safe.
None of the students in the school reported feeling sick.
At the same school in 2009, at least 20 people became physically sick suddenly, reporting symptoms of nausea and dizziness. The source of the sickness was never identified.
The similar incidents have some parents concerned.
"There must be something going on and connected, they're very old buildings," parent Mercedes Ramirez said.
Other parents said that they believe it's a coincidence that HAZMAT has been on school grounds twice.
"Actually I feel very safe, I feel that the city has that response system in place and that they were prompt to get here and that they have everything closed," said parent Gabriella Hernandez.
Coronado Police say SDG&E did a sweep through the school after HAZMAT, and say the gas connection is good.
Coronado police say Sacred Heart School plans to go back to business as usual Thursday.
