I wouldn't even begin to know how to answer him. I don't own a propane grill and probably never will. I remember when I was a volunteer firemen we responded to a bbq fire which the homeowner put out. That evening the guy went into attached garage and turned on a light and kaboom! The heavier than air propane found it's way in to garage because the poor bastard didn't turn the valve off after putting the fire out.
