Description
Hydrogen is a flammable, colourless, odourless, compressed gas packaged in cylinders at high pressure.
It poses an immediate fire and explosive hazard when concentrations exceed 4%.
It is much lighter than air and burns with an invisible flame.
High concentrations that will cause suffocation are within the flammable range and must not be entered
