    Hydrogen


    Hydrogen
    is a flammable, colorless, odorless, 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.


    PHYSICAL AND CHEMICAL PROPERTIES

    Molecular weight 2
    Melting point -259 °C
    Boiling point -253 °C
    Critical temperature -240 °C
    Relative density, gas 0.07 (air=1)
    Relative density, liquid Not applicable.
    Vapour Pressure 20°C Not applicable.
    Solubility mg/l water 1.6 mg/l
    ---------------------------------------------------------------------
    Appearance/Colour Colourless gas
    Odour None
    Autoignition temperature 560 °C
    Flammability range 4-75 vol% in air.
    Other data Burns with a colourless invisible flame.

    STABILITY AND REACTIVITY

    Stability and reactivity Can form explosive mixture with air.
    May react violently with oxidants.

    TOXICOLOGICAL INFORMATION

    General No known toxicological effects from this product.

    ECOLOGICAL INFORMATION

    suitable burner with flash back arrestor. Do not discharge into any
    place where its accumulation could be dangerous. Contact supplier if
    guidance is required.
