What are the flammable limits for motor gasoline?
Official USCG Answer & Rule Citation
Correct Answer: Option A — 1.4% to 7.6% mixture in air
Motor gasoline has a lower explosive limit (LEL) of approximately 1.4% and an upper explosive limit (UEL) of 7.6%. Concentrations within this range are capable of supporting combustion if an ignition source is present, making it a highly volatile and dangerous cargo requiring strict adherence to safety procedures.
