It is best not to spill meths when filling the burner, I use a syringe. Alcohol vapors can communicate flame, so fire doesn’t have to touch the liquid, it can ignite the vapor that comes from evaporating alcohol. Always be sure the flame has been extinguished when refilling the burner, outside in daylight it is often difficult to see the burning flame.
