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.
