If the shape of the fire is a person with two arms on both sides, as if she was yelling frantically, "Help! I'm on fire!" -- This symbol actually is originally from the shape of the flame, but I like to think that way. Whichever works for you.
Kształt ognia jest jak osoba z ramionami po bokach, gorączkowo krzycząca: "Pomocy! Palę się!" Symbol ten pochodzi od kształtu płomienia, ale wolę swoją wersję. Jak wam wygodniej.
