Okay, I'm getting myself confused on this section of code. Chapter 5.

I need to see if I can come up with a simplified level so, please let me know if this is correct.

Classes 1-2-3 describe the physical locations. Divisions 1 & 2 within each class deals with the explosive/danger levels.

Class X, Division 1 is the more severe of the grouping. This is the area where the possibility of explosion is imminent.

Division 2 within each class is a lesser degree of risk. This is normally a storage area environment.

Is the above a fair and accurate "Overview"?
