We use the heat of fire to cook meals, make hot water, melt metals, form glasses and build different varieties of products. 

Although beneficial in most cases, fire can cause disasters when it is out of control. Every day, thousands of fire accidents occur in homes, work places, savannas and forests with no obvious reason. 

By understanding what is needed to start fire, we can start controlled fire as needed, and prevent unexpected and uncontrolled fire.
