Ok. CO I can understand, but I don't see the risk of fire being any greater than with gas burners on a stove.
I have almost knocked my lit burner over when slinging a heavy pot of water that I hadnt lifted high enough into it. I am just cautious, Wouldn't want the burner in the house, I do not mind using it in the garage (door open), but I like to keep a nice clear work area around it. In my opinion t is easier to sweep something flammable over the flame of a burner than that of a stove.
