Therefore, as long as you maintain a good supply of fresh air to the fire, it should continue to burn, as long as the other conditions are met. Firefighters will also turn off the electricity in a burning building to remove a source of heat. This chemical process involves the transference of oxygen or electrons, which is responsible for the chemical reaction that causes combustion in a fire. How Is Fire Used As A Symbol?

This is because a facilitys level of risk factors in both the probability that a fire will occur and the severity of the potential harm that could be caused by a fire if it did occur. (known as a class-D fire), it becomes even more important to consider the energy release. In addition, they use a cold discharge to reduce the heat. Two additional elements, if present, create the optimal conditions for a combustible dust explosion to occur. For instance if there is fire breakout and we need to extinguish it, we just need to remove one element of the fire triangle thus: As soon as one component is removed, the fire cannot continue.
