Description

Description	Hydrogen gas is the density of the smallest known in the world, is the relatively minimal molecular mass of a substance, but also the most abundant element in the universe, only 1/14 of the air, that is, when 0 ℃, a standard atmospheric pressure, the hydrogen density of 0.0899 g / L. Therefore, hydrogen can be used as an airship, balloon filling gas (hydrogen gas is flammable because of security is not high, now more helium filled airship).
Usage	Hydrogen is mainly used as a reducing agent. Medicine to treat part of the disease with hydrogen.
Precautions	Hydrogen is a colorless, odorless and dangerous, toxic, flammable gas, and fluorine gas, chlorine, oxygen, carbon monoxide and air mixture has exploded, in which a mixture of hydrogen and fluorine gas at low temperature and darkness environmental explosion can take place spontaneously, the mixing volume ratio of the chlorine is 1: 1, in the light can be explosive. Since hydrogen gas is colorless and odorless, the combustion flame is transparent, its existence can not easily be found in the senses, the hydrogen added to the stench of ethanethiol in many cases, in order to detect the sense of smell, and color-imparting flame simultaneously. Hydrogen although non-toxic, physiologically inert human body, but if the hydrogen content increased air will cause hypoxia suffocation.
By Industry	Metal processing and manufacturing, medical and scientific research, food and transportation, petrochemical, laboratories and universities, photovoltaic and energy
