What are the hazards of hydrogen to the human body

Hydrogen is a gas that is particularly abundant in the air, and it is also a gas with the smallest density. It is only one-fourteenth of the mass of air and is also a particularly light air. We usually use hydrogen when blowing balloons. Since it is lighter than air, the balloon will rise into the air. When we use hydrogen effectively in our daily life, we must also pay attention to its impact. Let's take a look at the hazards of hydrogen to the human body.

Hydrogen is a colorless, odorless, non-toxic, flammable and explosive gas. It is explosive when mixed with fluorine, chlorine, oxygen, carbon monoxide and air. A mixture of hydrogen and fluorine can explode spontaneously in a low temperature and dark environment. When mixed with chlorine in a volume ratio of 1:1, it can also explode under light. Since hydrogen is colorless and odorless and its flame is transparent when it burns, its presence is not easily detected by the senses. In many cases, smelly ethyl mercaptan is added to hydrogen to make it detectable by the sense of smell and to give the flame color at the same time.

Although hydrogen is non-toxic and physiologically inert to the human body, if the hydrogen content in the air increases, it will cause hypoxic asphyxiation. As with all cryogenic liquids, direct contact with liquid hydrogen will cause frostbite. The overflow and sudden evaporation of liquid hydrogen over a large area can also cause oxygen deficiency in the environment and may form an explosive mixture with air, causing a combustion and explosion accident. It can form explosive mixture when mixed with air and will explode when exposed to heat or open flame. The gas is lighter than air. When used and stored indoors, leaks rise and are retained on the roof, making it difficult to discharge. If it encounters sparks, it may cause an explosion. Hydrogen reacts violently with halogens such as fluorine, chlorine, and bromine.

Through the above introduction, we now know the harm of hydrogen to the human body. In our daily life, while we effectively utilize hydrogen, we must also pay attention to the harm of hydrogen to our body. We must make the best use of its strengths and avoid its weaknesses. Especially for children, we should try our best to avoid contact with hydrogen, and have less contact with oxygen balloons to prevent accidents.
