Answers
Answer:
The following points are needed to keep in mind to control fire -
The fuel flow : If we want to control fire, then the fuel flow should be considered as the the most important factor. The fuel flow is directly proportional to the intensity of the fire.
The oxygen flow : Just like the fuel flow, the oxygen flow is similarly important. We can increase the fire by increasing oxygen flow and we can stop the fire by stopping the oxygen flow.
Heat : We can also control the fire if we are able to control the heat of the environment. If the heat of the environment reaches below the ignition point of the fuel material then it will be very difficult for the fire to survive for long.
Precautions : All the above mentioned things should be done under high amount of precautions. Because, fire can cause accident in any moment.
