Chemical mishap in school lab sends four to hospital after breathing issues

A minor chemical incident disrupted a school chemistry lesson yesterday. Four people reported breathing difficulties after an unexpected reaction in the lab. Emergency crews quickly arrived to assess the situation.

The problem began when an unintended chemical reaction took place during class. Three students and a teacher soon complained of respiratory irritation. Paramedics treated them on site before taking all four to hospitals in Krefeld for further checks.

A total of 32 responders attended the scene, including fire, rescue, and medical teams. Specialists in protective clothing examined the classroom but detected no dangerous substances. Portable sensors confirmed no elevated toxin levels in the air. The lab relied on natural ventilation, which may have helped limit any potential spread. After about an hour, authorities declared the area safe and returned control to the school.

No hazardous materials were found, and the site was cleared within the hour. The four affected individuals received hospital treatment as a precaution. School operations resumed once the all-clear was given.
