Good to hear.
I once knew a woman with cognitive impairment who was on oxygen by nasal prongs and somehow got someone to give her a cigarette and a match or lighter. She lit the cigarette with her oxygen in place and ended up with some nasty first degree burns on her upper lip and nose.
Theoretically, oxygen would make a flame burn more intensely, like blowing on a campfire or fire in the fireplace, but it should not cause an explosion. A spark, by extension, would also 'glow' more intensely, but not cause an explosion. So, setting something on fire in the shop would be the concern. As long as the flame or spark is not in your face or mask, in the 'cloud' of oxygen from prongs or mask, you should be OK. If a used rag or pile of sawdust catches on fire, with extra oxygen in the area it would burn more intensely, which could create a rapidly progressive situation that could be very hazardous to you and the shop and the house, etc.
As you know, many finishes and solvents contain petroleum distillates.
