Hydrogen MSDS

What is Hydrogen:

Hydrogen is a colorless, odorless, nonmetallic, tasteless, highly-flammable gas. Hydrogen reacts with every oxidizing element. Reactions with Hydrogen are dangerous and may cause fire or explosion. Gas/Air mixtures are explosive. Exposure to fire or intense heat, containers of hydrogen may rupture violently and rocket.

Hydrogen Exposure and Health Risks:

Hydrogen is not toxic, but it is an asphyxiate and will cause suffocation as it displaces the oxygen from the air. High concentrations Hydrogen in the air cause a deficiency of oxygen which can result in dizziness, unconsciousness, or death. Direct contact between the liquefied gas and the skin can cause frostbite.


The table below summarizes the most-recent exposure limits.

Measuring Hydrogen:

Hydrogen levels in the air can be measured in units of parts per million (ppm). Many of our products have digital communication capabilities for easy monitoring and control. We carry portable and fixed hydrogen monitors sensors. All of our Hydrogen products can be viewed HERE.
