Overview
- A smartphone's lithium-ion battery ignited inside a mother's handbag in a Butzweiler primary school classroom during project week on Thursday, prompting an immediate firefighting response.
- Firefighters used a dry-powder extinguisher to put out the device quickly, but the released powder was inhaled by the mother and several pupils and caused respiratory complaints.
- Emergency units including multiple volunteer fire brigades, three ambulances, an emergency doctor and disaster-control personnel treated the mother and seven children on site and no one needed hospital admission.
- After the room was ventilated and cleaned, school activities resumed, and authorities described the incident as contained with only light injuries reported.
- Technical experts cited by coverage noted that lithium-ion batteries can enter thermal runaway at high ambient temperatures (about 35°C or above) and advised avoiding direct sun, high heat and following manufacturer charging and storage guidance.
