A man wearing a white shirt and blue jeans as well as a mask over his mouth stokes a fire.
A guy in cloth pants and shirt is wearing something on his face to protect hist lungs puts out a fire.
Putting out fire would mean that it is being extinguished and not stoked.
When someone stokes a fire they make it larger. When one puts out a fire they make it smaller until it is gone. One cannot do both simultaneously.
To put out a fire is the opposite of stoking a fire.
