Fires are sometimes caused by a rapid combination of oxygen, and are sometimes caused by oil or gasoline. If there is fire and anything that can blow up , it will blow up. If there is enough oxygen or chlorine there will be a lot of explosions. If you’re house is ever on fire crouch down low to get under the smoke crawl outside , meet up with you’re family , next , go to a neighbor’s house and call the Fire Department. But never ever go back into a burning building because you can get a serious injury or even be killed.
