Question:
What are Upper and Lower Explosive Limits?
A
Answer:
It is the point where a vapor such as gasoline (liquid gasoline does not burn) is too rich or too lean to explode. This is the same as when you are adjusting the carburetor on your lawnmower, it has to be between the upper and lower explosive limits in order to run. From general hazardous locations theory.
