Answers
Answer:
D) Run away
Explanation:
When a domestic gas cylinder explodes, the reaction time is quite limited and there is only much that you can do. When the gas cylinder has already exploded the best thing to do is to run away from the explosion.
The best method of putting out a flammable gas fire is by using carbon dioxide extinguishers.
All the choices given in the question are not good methods for putting out flammable gas fire.
Here are the different classes of fire and the best way of extinguishing them:
- Class A fires - These are fires caused by burning of paper, wood, wool and/or anything that burns and leaves ash. These fires are best put out (extinguished) by water.
- Class B fires - These are fires caused by flammable liquids like gasoline. These fires are best extinguished by smothering methods like covering with a wet blanket
- Class C fires - These fires are caused by electric currents. These types of fires are best extinguished by using carbon dioxide extinguishers.
- Class D fires - These are fires that are caused by flammable metals like magnesium. These types of fires are best extinguished by dry powder extinguishers.
- Class K fires - These fires are caused by kitchen items like cooking oil and animal fat. These fires are best extinguished by Class K fire extinguishers which work by spraying a gentle mist on the fire and providing a solid barrier.
NOTE: In case of a gas leakage, the best thing to do is:
- Find and close the point of leakage
- Ensure that you open all the windows and doors.
- Remove/switch off anything that can ignite
- Leave the house to a safe distant and wait for gas to flow out
If the domestic gas cylinder bursts then you should run away because if a domestic gas cylinder bursts then flying shrapnel would hurt you. When one ruptures, the expansive force sends shrapnel flying in all directions.
