A UK man has died after his e-cigarette exploded into flames and ignited a oxygen concentrator he is believed to have been using, according to an RT.com news article.

The 62-year-old man was found dead in the living room of a home in Wallasey, a town near Liverpool in North West England.

While the exact cause of death is yet to be established, the subsequent fire investigation by Merseyside Fire and Rescue Service (MFRS) found that “an e-cigarette that had been charging in the bedroom exploded, caught fire and particles ignited the oxygen tube of an oxygen concentrator,” a spokesperson for MFRS said.
