Authorities canceled classes Tuesday at a Colorado school after a chemical device “went off,” according to police.
Nine patients from SkyView Academy in Highlands Ranch were being evaluated following the incident, according to a statement posted on the Douglas County Sheriff website around 1 p.m. New York time.
Four students and one teacher were taken to a hospital with minor respiratory issues, a sheriff spokesman said.
Three students and a teacher were taken to a hospital as a precautionary measure following the incident.
“We are determining if this is a malicious or accidental event,” the sheriff statement read.
The school asked parents to pick up students from the school gymnasium. Skyview has students ranging from kindergarten to the 12th grade, according to its website. It is about 20 miles south of Denver.
Earlier this month a botched science experiment at The Beacon School in the Upper West Side badly burned two students. The dangerous mishap resulted in the Fire Department slapping the school with eight safety violations. The teacher who was handling the chemicals at the time of the fireball continues to work while the incident is investigated.
