A routine Monday morning at Hazelwood West High School took a sharp turn when an aerosol chemical irritant was sprayed into a crowd of students, according to police. About 40 students reported symptoms, authorities said; one was taken by ambulance for evaluation, while several others were later picked up by parents for self-treatment at home. Not exactly the kind of surprise anyone wants between classes.

Police response and custody

According to First Alert 4, Hazelwood police said a teenager bolted from the scene after spraying the chemical but was later taken into custody. Police told the outlet that roughly 40 students reported being affected and confirmed that one student was transported by ambulance for further evaluation.

Health risks and recommended steps

Riot-control agents and similar aerosol irritants can trigger burning eyes, coughing, throat irritation and shortness of breath, and they can worsen asthma or other lung conditions. The Centers for Disease Control and Prevention advises anyone exposed to move to fresh air, rinse affected skin and eyes thoroughly with water, and seek medical care if symptoms do not ease. Regional poison control specialists are also available for guidance at 1-800-222-1222. CDC
