Germany: School evacuated over suspected gas exposure

Exposure to a suspected irritant gas has affected at least 70 people at a school in southwestern Germany, according to a media report.

Both students and teachers were among those who experienced slight health effects at the school in the town of Singen, German news agency dpa said.

The school was evacuated and police cordoned off the area Wednesday. It was not immediately clear if the incident involved a leak or a spill.

Irritant gases include ammonia, chlorine, hydrogen chloride and sulfur dioxide. Inhaling their vapours can cause respiratory problems.
