DENVER—Jefferson County Open School is closed while the district tries to determine what made dozens of kids sick on Monday.
Seven students at the suburban Denver school were hospitalized and about two dozen others and a teachers’ aide were decontaminated on site after complaining of skin and eye irritation.
West Metro Fire Protection District spokesman Gary Armstrong said Tuesday tests for caustic chemicals have turned up negative and no samples were able to be collected for sampling.
Students on the playground of the Jefferson County Open School in Lakewood began complaining just before 1 p.m. Monday. Firefighters set up a decontamination tent and evacuated the pre-kindergarten through 12th-grade school as a precaution.
