The non pressurized stoves can't flare. The Origo is as idiot proof as can be. I am sure you could put one out with a large glass of water but the knob on the front of the stove moves a plate that slides over the burner and smothers the flame.
If a pressurized stove flares, what happens is more fuel under pressure passes out the metering valve in a mist and you have 3 or 4 foot flames. You are not going to put it out until you get the fuel turned off.
