The Apple retail store located on Bahnhofstrasse in Zurich, Switzerland was evacuated on Tuesday following a situation with an overheated iPhone battery and its injury of a repair worker (via Reuters and Swissinfo.ch). Zurich police said that the incident happened as the worker was removing the battery from the iPhone, subsequently overheating and "slightly" burning his hand.
It wasn't confirmed which iPhone was the source of the incident, but afterwards smoke began building up within the store, leading to the temporary evacuation of around 50 customers and employees from the premises. In addition to the repair worker, seven other people required medical attention but none were hospitalized.
The police mentioned that Apple staff responded quickly to the overheated battery by sprinkling quartz sand over it and containing the smoke as fast as possible.
“At the same time, there was a slight build-up of smoke, which led to around 50 customers and employees having to leave the business temporarily,” a police statement said.
“The staff responded well and correctly. It sprinkled quartz sand over the overheated battery so that the smoke could be contained and sucked out after switching on the ventilation.”
According to the police statement, forensic specialists are now examining what caused the incident in the first place, so no explanation was given at the time of writing. Apple has yet to comment on the situation.
