Default Internal Flame?

From Quora, I checked the date, definitly not April 1.
Quote:
Patient got burnt by mid surgery explosion when laser ignited fart. This happened in Tokyo Medical University Hospital in 2016; a Japanese women in her 30’s was undergoing a surgery on her cervix, the lower part of the uterus. When surgeons pointed the laser towards cervix, the woman farted or passed gas, the laser ignited the gas and caused a blaze that ended up burning the surgical drape, and her waist and leg skins.
Gas released from intestine is a combination of carbon dioxide, hydrogen, nitrogen, oxygen and methane; hydrogen and methane in the gas make it flammable. In one of the scenes of Jim Carrey film “Dumb and Dumber” the ignition of farts by a match placed near the anus was shown; like this movie scene around one third of the population can produce combustible level of methane during flatulation; amount of methane increases when one eats a lot of foods containing high levels of methane, such as broccoli, cabbage or kale.
To determine the cause of the blaze Japanese investigators used a dummy to recreate the incident. They ruled our flammable material or equipment malfunction as the cause. The report recommended fire-fighting training for operating room staff and taking steps to physically prevent methane from interacting with laser beams. No doubt this incident will leave a significant effect in the history of laser surgery.

Seems dodgy to me. An average adult human normally farts only about 2 litres of gas per day, and rarely much more than a single litre on any one occasion, unless they have an intestinal upset. Not all of that gas is flammable, and besides a litre or even two litres fart is not going to produce a sustained flame. The flaming fart must therefore have ignited some medical alcohol nearby.
