A grandmother was killed after sparks from an oxygen tank used to treat her for suspected coronavirus set fire to an armchair and exploded, an inquest heard.
Lynn Hadley, 68, tragically died after the blaze ripped through her home in Walsall, West Midlands, late afternoon on Easter Monday.
Paramedics had been called to the property by her concerned family members after she started to show symptoms of Covid-19.
But as crews started oxygen treatment, sparks flew from the device and ignited the armchair where Mrs Hadley was sitting.

The inquest was told Mrs Hadley could not be rescued as the flames took hold and she died in the chair as a result of "fatal burn injuries."
Police, firefighters, two more ambulances and a Hazardous Area Response Team were sent to the scene of the blast, which completely destroyed the roof and conservatory.
Senior coroner for the Black Country Zafar Siddique opened and adjourned an inquest into her death today.
He said: "There was an incident on April 13, a severe fire in the living room of the property in New Street.
"The deceased had been suffering from a high temperature and fatigue, so her daughter called 999. The ambulance crew assessed her for suspected Covid-19.
"Her oxygen levels were low so oxygen therapy was needed.
"Within minutes of the paramedic plugging in the oxygen cylinder, sparks were witnessed. It set fire to the armchair where the device was sat.
"Paramedics escaped the house, and family members also left the house.
"By the time the paramedics went back in to rescue Mrs Hadley, the fire had developed too much. She was recovered from the armchair.
"I will adjourn this hearing to allow the Health and Safety Executive to investigate and give a report."
The Health and Safety Executive is also investigating the incident and will provide updates to the coroner.
Mr Siddique expressed his condolences to the family and adjourned the hearing for a pre-inquest review to take place on June 30.
