Salisbury Township police and EMS crews were dispatched to the private school, 1151 South Cedar Crest Blvd., when a person became sick around 9:30 a.m. on April 27, said the department in a release.
When a second person fell ill, Western Salisbury firefighters were called to the scene to conduct air quality checks, police said.
They found "no obvious levels that were cause for concern," but still evacuated the building "as a precaution," authorities wrote. Officials will remain on campus with metering equipment "at the request of the school and maintenance," they added.
