Hello everyone, I am a portable water-based fire extinguisher, which was bought by the hostess when she attended a fire safety knowledge lecture two years ago. I was dressed in silver-white clothes, and my slender figure was cylindrical, and I had a duck's beak, which was always wide open.

Our family is very large, there are many brothers and sisters, and the eldest has foam as a filler, and people call him a foam fire extinguisher. He specializes in fires caused by oils, greases, etc. Therefore, fires caused by flammable gases or electrical equipment such as gas have to ask for the second dry powder fire extinguisher in our family, which is made of sodium bicarbonate dry powder as a filler, and the responsibility for dealing with this kind of fire is handed over to him!

The third child of our family is an acid and alkali fire extinguisher, which is used for the initial disaster of general combustible substances such as bamboo, wood, cotton, wool, grass, and paper. If there is a fire in the warehouse of valuable instruments and equipment or an important archive room, we should ask our family's old quad carbon dioxide fire extinguisher to come out, so that he can do not leave a trace after extinguishing the fire, so that the damage can be minimized.

My siblings have settled in schools, hotels, supermarkets and other public places. Although many people have bought us home, but lack of awareness to give us a physical examination on time, only put us at home as decorations, or even put in a hidden place at home, if there is a real fire, maybe even the owner has forgotten my existence. There are more people who don't know my body structure and the principle of extinguishing fires, and they don't know how to use it, and it will still cause disasters at critical moments.

Let me tell you how to use a fire extinguisher. When a fire starts, first open the safety latch, aim the nozzle at the fire, press the switch, and the liquid inside will be sprayed out, extinguishing the fire as quickly as possible. Of course, I also have an expiration date, which is generally 3 years.

Friends, let's popularize fire safety knowledge and minimize the occurrence of tragedies.

A fire extinguisher is a tool to eliminate small fires that occur in life. And there are many types of it, and they can extinguish fires from many different things.

The appearance of the fire extinguisher is red, which is very eye-catching at a glance, and can also show a certain warning effect. It is usually a barrel type, with a control switch and a pipe that can release fire-fighting materials. Some are dry powders; Some are foam; There are also new chemical fire extinguishers and so on.

At present, the fire extinguishers we usually use are all internal pressure type, that is, a certain pressure is added to the fire extinguisher in the manufacturing process, so that in the process of use, the fire extinguishing raw materials in the fire extinguisher can be sprayed to the place where the fire is on fire. When using, shake the fire extinguisher a few times to loosen the fire extinguishing materials in it. For foam fire extinguishers, the fire extinguisher should be turned upside down to neutralize the fire extinguishing materials inside, so as to be effective.

The most important thing when using is to unplug the safety bolt of the fire extinguisher, so that the switch of the fire extinguisher can be pressed, and the fire extinguishing material inside can be sprayed out to extinguish the fire.

Dry powder fire extinguishers are used to extinguish fires caused by oil, electrical appliances, and common fires in life; Foam fire extinguishers can also be used to extinguish fires caused by oil, and can also extinguish fires caused by chemical raw materials, but it cannot be used to extinguish electrical fires.

We need to be familiar with how to use the fire extinguisher, so that it can be our good helper!

Yesterday, Mom and Dad had dinner with an important guest, and I didn't go because I didn't finish my homework. Mom and Dad are gone, leaving me alone. Last night's sky was pitch black, with a bright moon embedded in the night sky, and stars winking mischievously in the sky.

In the beginning, I was especially happy because I could be alone at home. I finished the rest of my homework in 10 minutes, and then I was able to watch TV and play on the computer. I was very happy at the time.

When I was playing on the computer, there was a small ghost story in the bottom right corner of the computer screen, and I read "Now it's just a little girl at home, and then." My heart was tangled and my body trembled because I was afraid of it, of the "ghost". I heard that "ghosts" are the most afraid of light, so I turned on all the lights in the house, not even the night light.

But then I thought: the light should be the sun's rays, where does the sun come from at night? At this time, a gust of wind blew the curtains, and I hurriedly ran over to close the window.

My heart was pounding with fright, like a fawn, and I was terrified. I was thirsty and wanted to drink water, but I was afraid that there was a "ghost" hidden in the water bottle, and as soon as I opened the cork, the "ghost" would come out and eat me, so I had to endure not drinking it, and I didn't dare to touch any container. It's funny to think about it now.

At that time, even the "buzzing" sound of flies flapping their wings made me feel relieved. Three hours seemed like three years had passed, and I was relieved to see my parents come back.
