If I remember correctly, the flame also changed colour when combustible gas was present, giving the miners a relatively safe warning to get out and ventilate the mine.

On first glance it appears that the temperature of
the metal and it's ability to cool a local zone below
the ignition temp that would "prevent " the escape
of the ignition source to the atmosphere.
The dead zone in an IC engine can be more than 1 mm
thick under some operating conditions.
Still it seems that having a combustible mixture of
methane in the air you're breathing can't possibly be
good for you even if it doesn't ignite.
