How to use a fire extinguisher | in urdu | 2019

It is my first video at dtube platform. I'm already working on YouTube. Language of this video is urdu because Majority of asia subcontinent understand urdu language.
If you like my videos then I will try to make videos in English also.
In this video I am telling about different types of fire extinguishers. And how to use them on fire. But only one type of fire extinguisher "Dry powder" discussed in this video.
Please comment about my work that how I make videos better to better.
