open flame
Naked burning source
An open flame is fire that burns exposed to air rather than enclosed in a chamber or behind glass—a candle, gas burner, or campfire as opposed to a furnace or sealed heater.
Safety warnings commonly prohibit open flames near flammable materials: No smoking or open flames.
The phrase emphasizes the fire's accessibility and potential hazard.
