This time, a 33-year old excavator driver from Korea. Mr. Seo was found lying dead beside his excavator in a stone quarry by his friends, with a cellphone in his pocket that had a severely melted battery, resulting in a burnt and fractured chest. Judging by the image, this is most probably a Samsung handset. There are not a lot of options to avoid this, but putting the phone in a pouch/case might give you some precious seconds but in reality this is a somewhat rare occurence as battery are designed not to explode, but to melt (yikes!) when things go wrong.
