The terrible gas

One day, I really realized the horror of gas.

That day, I was combing my hair and suddenly smelled a pungent smell. My mother also smelled it and said strangely: "What does it smell like? The smell of mutton?" Then she ran to the kitchen and started cooking. I opened the lid of the pot where the mutton was cooking, smelled it, looked at it, and said to myself, "Is this mutton bad? It's impossible!" The strange smell became stronger and stronger, and I suddenly said: " Isn't it gas?" This sentence reminded my mother, and she hurried to the kitchen again, hey! Sure enough, the fire was out, and the gas stove kept spewing gas. My mother was frightened and hurriedly turned off the gas.

After turning off the fire, we opened the windows of every home. My mother and I went to the only small home that didn't smell of gas. We closed the door and smelled worriedly outside the door. Our hearts were beating fast, we were nervous and worried... After about half an hour, the gas smell in the house was almost gone, and our uneasy hearts were able to calm down.

After the incident, my mother was very frightened, and we also summed up a lesson: we should not leave the house with the fire on at will.

Thinking about it now, although it was a near miss, if we had not discovered in time that the gas was spewing out too much, even if we knew it was gas, we would not have the strength to turn off the gas and the gas. If you leave home and don't even have the strength to climb out, that means there is a possibility of losing your life.

It is very important to cherish life and pay attention to safety. There is only one life, we must cherish it and not let it be damaged!

Let us be more vigilant, strengthen protective measures, and keep the terrible gas away from us! Let all dangers stay away from us! Let our lives no longer be threatened! Let the flower of life never be broken! 2. A 300-word essay on gas

Every family cannot live without gas, but many people have lost their lives because of gas.

What is gas poisoning? Gas poisoning usually refers to carbon monoxide poisoning. Carbon monoxide is a colorless, odorless, nontoxic gas that is lighter than air and easy to burn. It burns with a blue flame. Carbon monoxide content in the air exceeding 30 mg per cubic meter can cause poisoning.

Now let me tell you some ways to prevent gas poisoning: Do not use coal stoves or cook in closed rooms, otherwise poisoning will occur due to lack of ventilation. Poisoned people will have headaches, general weakness, vomiting and other symptoms; severe cases should be sent to the hospital for rescue in time. If the medical staff has not arrived yet, you should immediately open the window and put the patient in a place with fresh air; if the patient is seriously ill and unconscious, you should loosen the patient's clothes buttons to keep breathing smooth.

Therefore, we must use gas safely and do not forget to turn it off after use, so that gas poisoning will not occur! 4. Carbon monoxide composition

My name is carbon monoxide. It is a compound composed of a carbon atom and an oxygen atom. It is a gas that is less dense than air, colorless, and odorless. Although my molecule only has one less oxygen atom than the carbon dioxide molecule, our properties are very different. In the coal stove, you can often see a blue flame appearing above the coal seam, which means I am burning.

I can burn in the air and release a lot of heat when burning. But I am highly toxic. Once it is inhaled into the lungs and combines with hemoglobin in the blood, the hemoglobin will not be able to combine with oxygen well. In this way, the human body will be deprived of oxygen, which can range from headache to death due to lack of oxygen.

Specifically, he said: On some ocean surfaces, my content is only 0.04 parts per million, while in a crowded city, on a windless day, the content in the ground air can reach 360 ppm. . Generally, the content is below 50ppm and is considered safe. If the content reaches 1000ppm (that is, it is equivalent to 1 volume of carbon monoxide for every 100 volumes of air inhaled), just stay there for a while, you will feel headache and nausea. When the content of carbon monoxide in the air reaches 10000ppm, people will stay there even for 10 minutes. , will also cause poisoning and death.

Since I have no color or smell, I am not easily noticed by others, so people have to be especially careful around me. Coal fires are used for heating in winter. If the exhaust at home is poor, people will suffer from gas poisoning. This is what poisoned me - carbon monoxide. I'm often guilty of this.

However, I also have many advantages. Because of its reducing properties, it is often used as a reducing agent in the metallurgical industry to reduce metal oxides to produce certain metals. For example, I reduce iron oxide in iron ore at high temperatures, and at the same time, carbon dioxide can be generated.

I have both flaws and strengths. Please believe that with the development of science and technology. Me——The application of carbon monoxide in human life will definitely become more and more extensive. 5. A 300-word essay on safe gas

But how could the driver see him performing the hurdle maneuver? In the end, no one benefited, and they all fell into a pool of blood.

Shot 2: Winter is here, so naturally I like to take a few more minutes in the shower. Then we need to pay attention to the gas problem, but some people still use gas carelessly.
