Question

What happens if we breathe hydrogen?​

Answer 1

Answer:

Inhalation: High concentrations of this gas can cause an oxygen-deficient environment. Individuals breathing such an atmosphere may experience symptoms which include headaches, ringing in ears, dizziness, drowsiness, unconsciousness, nausea, vomiting and depression of all the senses.

Answer 2

Explanation:

At very high concentrations in air, hydrogen is a simple asphyxiant gas because of its ability to displace oxygen and cause hypoxia (ACGIH 1991). Hydrogen has no other known toxic activity. ... Thus, occupational exposure standards are set on the basis of the explosivity of hydrogen rather than its toxicity.
