MAQ Flammable Liquids
Wanted to get another opinion on NFPA 400 table 5.2.1.1.3. There are two footnotes (a and b) that state you can increase the MAQ by 100% if stored in approved cabinets and then another 100% if properly sprinklered. Now, the statement that these footnotes can be applied accumulatively is causing issue with a consultant. Does this mean I could go from say 120 gallons to 360 or 120 gallons to 480 gallons?

480 gallons. The footnotes specifically say that it is cumulative.
Here's an NFPA blog post verifying that interpretation:
