The pure oxygen in oxy acetylene is to give a cleaner hotter flame true. But trust me, pure oxygen is quite capable of making interesting and upsetting things happen when a source of ignition is added, there's more than a few accidents happened do to engineers smoking in overalls that have become impregnated with oxygen due to leaking regulators/pipework in an enclosed area.
As I say though, I highly doubt that an ecig coil ignited that oxygen, if that is indeed what happened, unless the regulator/pipe work had saturated all her bedding with pure oxygen - no fuel. And a fire needs oxygen, ignition source and FUEL to burn.
Amongst other things, OH carries out confined spaces investigations mostly for civils (pipelines etc) and housebuilding Not nice - H&S blokes can develop a very dark sense of humour
However, just having a convo with him about this as he's also recently done Hospital estates H&S at Barnsley and studied all this to give staff inductions. -so we have - a lot of fires of this sort are caused elderly or older people, especially those with diminished lung function who are on oxygen therapy and feel that the safety regs don't apply to them, they are immune and so spark up a crafty fag: The cellular blankets that hospitals use are known to be a major fire hazard as they hold a lot of air/gas because of their construction: until quite recently leaks developing on faulty regulators on oxygen cylinders was a huge problem - in theory this has now been rectified, but incorrect use or fitting of the oxygen delivery system is still a problem. (and now I'm preaching to the converted as I know you know this gords , but many members might not) ... and for now, last but not least - A saturated oxygen environment lowers the flash point of combustible substances by a huge amount, so something that would ordinarily need an extremely high temperature to ignite, say a thousand or more degrees Celsius, will now only need about 150deg Celsius ....
So ... 99 reasons why this might have happened, and an e-cig ain't one...
