What effect does hydrogen gas have on the human body?

Answer 1

Pure hydrogen gas contains no oxygen so asphyxia is a possibility (causing dizziness possibly leading to unconsciousness and ultimately death due to insufficient oxygen reaching the brain). Hydrogen forms explosive mixtures with air or oxygen, so the possibility of ignition makes inhaling hydrogen very hazardous (would you want your lungs to look like an exploding hydrogen balloon?). Industrial hydrogen may be contaminated with other gases depending on its source and some of these could be harmful (carbon monoxide for example).

A mixture of hydrogen and oxygen called hydreliox is used in very deep diving (500-700m) to avoid nitrogen narcosis (the dissolution of nitrogen in blood due to high pressure). Some mixtures also contain helium. I believe the mixture must be handled with extreme care since it is explosive.

Answer 2

Inhaling pure hydrogen gas in small amounts is generally safe and does not have any harmful effects on the human body. However, inhaling high concentrations of hydrogen gas can displace oxygen in the air and lead to asphyxiation. It is important to handle hydrogen gas with care and in well-ventilated areas.

Answer 3

it could make you feel sick if inhaled to much, and your nose might hurt a bit too.
