That was the finding of Coroner Mr Brian Sherrard as he examined the events surrounding the death of Mrs Dora Jane Wilkinson in August 2007.
Dungannon Coroners Court heard that Mrs Wilkinson was discovered at her home in Springfield Crescent – where she'd lived for 40 years – on the morning of August 18th last year.
She died some 13 days later in the Royal Victoria Hospital in Belfast having sustained 35% burns resulting in eventual multiple organ failure.
The Court heard firstly from Mrs Joy Gates – one of the victim's daughters.
Both Mrs Gates and her sister were their mother's principal carers and were with her on a daily basis.

Haze

On the morning of the fire Mrs Gates recalled how she entered the house around half past nine, only to be met with a 'misty thick haze from the hall, like a heat haze'.
She remembered 'thick black smoke' and the smoke alarm going off.
The witness told the Court her mother was a diabetic but her general health had been good, and she'd been seen the previous day by her sister (Mrs Wilkinson's other daughter) who described their mother as being her 'usual self'.
Mrs Gates said when she went into the house that Saturday morning she had tried to call her mother's name but the smoke was so dense it was like 'going through a black tunnel'. "It was completely black. There was nothing to see", she said.
The Court heard how emergency services arrived at the scene quickly.
Mr Andrew Graham, from the Northern Ireland Fire and Rescue Service, and Watch Commander at Dungannon Fire Station said crews were mobilised at 9.56 on morning of Saturday 18 August.

Rescue

Arriving at Springfield Crescent at 10.04 police told them there was a lady in the bedroom of the house and crews donned breathing apparatus to attempt a rescue.
Watch Commander Graham noted a second crew was summoned to help carry out the casualty and she was handed into the care of paramedics who took her to Craigavon Area Hospital at 10.26.
The fire officer said he'd been involved with Crime Scene Investigators to determine the cause of the blaze. They ascertained the bedside halogen lamp had fallen over and the heat from the lamp had set the bed on fire.
Constable Shauna Scullion, Dungannon PSNI was on duty that morning and attended the scene of the fire.
She told the Coroner how both she and her colleague went into the house as far as the entrance to the bedroom but were 'fought back by the smoke'.
Mrs Wilkinson was found by fire crews 'either on or right beside the bed', she noted.
The victim was taken from CAH to the Royal Victoria Hospital Intensive Care Unit at 6.26 that evening.
Studying medical evidence supplied to the inquest, the Coroner said Mrs

Complications

Wilkinson's condition was reviewed regularly but her health was complicated by an underlying heart condition and a chest infection.
During an assessment carried out by medics on August 30th it was found that the prognosis was poor and survival was not expected.
Mrs Wilkinson was placed on a limited DNR (do not resuscitate) system, and made comfortable.
Following her death on the evening of August 31st, a post mortem was carried which concluded that death had resulted from multiple organ failure due to 35% burns.
The pathologist found that her diabetes and an underlying swelling of the heart muscle would not have helped her overall chances of survival.
Presenting his evidence, Ian McNeill, Crime Scene Investigator from the PSNI in Dungannon, said he was satisfied there was no crime involved.
"The house was secure and intact", he said, "and the smoke alarm in the house was working."
It emerged a stool in the bedroom had toppled over and Mr McNeill said it was difficult to determine if the halogen lamp had fallen off it and then caused the fire.

Contained

An examination of the scene showed the blaze was contained to bedclothes on the left hand side of bed.
"The base of the lamp was intact, as was the flexible neck, but the bulb was burnt away", he said.
The carpet below the lamp had been burnt through and the floorboards charred, but there was no presence of accelerants.
How long the fire had been burning for was uncertain, the Court heard.
Handing down his ruling Coroner Mr Brain Sherrard found that Mrs Dora Wilkinson died from multiple organ failure due to 35% burns sustained in a bedroom fire at her home on August 18th, 2007.
And he concurred with the expert evidence presented which suggested the fire started when a halogen lamp set fire to the bedclothes.
