Liquid hydrogen description

Hydrogen is a chemical element with symbol H and atomic number 1. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Non-remnant stars are mainly composed of hydrogen in the plasma state. The most commonisotope of hydrogen, termed protium (name rarely used, symbol 1H), has one proton and no neutrons.

Hazards & Transportation

Hazard Statements: 

H220:Extremely flammable gas. 

H280:Contains gas under pressure; may explode if heated. May displace oxygen and cause rapid suffocation. May form explosive mixtures in air. Burns with invisible flame.

Extremely flammable gas. Contains gas under pressure; may explode if heated.

Burns with an invisible flame.  

Can ignite on contact with air.  

High pressure gas.

Can cause rapid suffocation.

Extremely flammable.

May form explosive mixtures in air. 

Immediate fire and explosion hazard exists when mixed with air at concentrations exceeding the lower flammability limit (LFL). 

High concentrations that can cause rapid suffocation are within the flammable range and should not be entered. 

Avoid breathing gas.
