DENVER (AP) -- Five students at a suburban Denver school were hospitalized and about two dozen others were decontaminated on site after complaining of skin and eye irritation.
The Denver Post reports 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.
Scott Rogers, chief of the West Metro Fire Protection District, says investigators have eliminated pepper spray and fertilizer as possible irritants, but it's still unclear what caused the students to react. First responders don't expect any long-term or lingering effects.
Winds were coming out of the northwest at 15 mph at the time, and investigators are searching the area for a possible source of the irritation.
