Morning Tish,
As a former welder, sucking up oxygen should be done with great care as
just about anything burns in the presence of pure oxygen. All it takes is
a spark and - WA LA - no more hair and a serious burn.
You mean, burn, not explode, I suppose. Can you elaborate a bit?
Many materials cannot be ignited easily with a spark.
If you mean, explode, then most gases have a narrow range of
concentration that can produce an explosion.
I had a chart of these different gasses and the concentration range
required to produce an explosion at one time.
I use oxygen in my den when walking on the treadmill. I have intended
to do a concentration percentage, using the 5 liters per minute and the
volume of the room.
In this case, I don't think the hazard is nearly as great as I have been
led to believe by the non-technical.
There is a gas heater about 25 feet away. Sometime I turn it off,
including the pilot.
