    1. The atmosphere in a tank m igh t be too

    lean if it is:

    A. Capable of supporting combustionbecause the hydrocarbon content is

    above the UFL (Upper Flammable Limit)

    B. Capable of supporting a fire once started C. Incapable of supporting combustion

    because the hydrocarbon content is

    below the (LFL) Lower Flammable Limit D. Not safe for ballasting

    Flammable Lim it or Explos ive Range

    If the oxygen is less than 10% inside a tank,

    the hydrocarbon vapor will not burn andtherefore it will be classified as Too Lean .

    But if oxygen is more than 10% inside the

    tank there will be a chance the hydrocarbonvapor will ignite and it is called Too Rich.
