The plaintiff started a fire near some junked cars in a field to keep warm during a cold winter day. He was wearing a permapress shirt composed of 50% cotton and 50% polyester under his jacket. Suddenly the fire seemed to explode and the right side of his head and right shoulder were burned. Investigation revealed that there was gas in one of the tanks of the abandoned cars and there was no gas cap on the tank. A flashback arrester could have prevented this accident. It was also learned that the permapress shirt he was wearing melted from the heat of the fire and formed a napalm like substance which added to the severity of his burns. It was interesting to note that the inner lining of his jacket was not burned even though the shirt under it melted.
