Question

Question.
1. Why is water not used in controlling electrical fires.
2. What happens when there is incomplete combustion?
3. How carbon dioxide extinguished fire.
4. If the clothes of a person catch fire, how you save that person.
5. Name any four places where not allowed to take any burning materials.​

Answer 1

Answer:

1.)Water is a conductor of electricity, so it can easily conduct electric current and cause danger of electric shocks or short-circuits. Therefore, water can not be used to control the fire involving electrical equipment. ... So it does not catch fire.

2.)Incomplete combustion occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide. The carbon is released as soot . Carbon monoxide is a poisonous gas, which is one reason why complete combustion is preferred to incomplete combustion.

3.)Carbon dioxide extinguishes fire by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well.

4.)If your clothing catches fire: STOP where you are—moving or running feeds air to the flames and worsens the fire. DROP to the floor—if you stand up, the fire can burn your face. ... ROLL slowly on the floor or ground, in a rug or blanket if you can.

5.)By most standards including the International Fire Service Training Association (IFSTA) there are 4 stages of a fire. These stages are incipient, growth, fully developed, and decay.
