Within a car, aircraft, hotel, and home, there are so many items made of
plastics or petroleum products that the off gases can combust in about a minute
and a half. So when the woman who opened the back door said, "I knew it
wasn't a good scene. I figured with all that fire that they were gone, man.
There were just so many flames. Within maybe 90 seconds, the car was fully
engulfed" that is a normal timeframe.The fumes are toxic and
combined with the flames are deadly.
