I'm doing the International Code Campus practice exam for the 2009 Fire Plans Examiner test. There are several questions related to Table 2703.11.1 (control areas in group M, etc).
A typical question would be "What is the maximum number of gallons of a class 3 oxidizer would be allowed in indoor control areas in a 2 story type M occupancy where a sprinkler system is installed per 903.3.1.1 and the product is in approved storage cabinets in accordance with 2703.8?". Actually, I believe this is the actual question.
The base amount in the table is 115 gallons.
The number of control areas would be per Table 2703.8.3.2. I come up with (7) control areas.
4 on the main floor would = 460 gallons per area totaling 1840 (increasing footnotes b and c apply accumulatively).
3 on the 2nd floor would = 345 per area (due to the 75% above grade plane reduction) x 3 (control areas) = 1035.
Total amount I come up with is 2875 gallons. Their answer is 2415.
In the calcs they provide, they do not include the 'cabinet 100% increase' provision, but rather only 115 gallons (base amount only, with no 100% accumulation).
I've gone over it several times and come up with the same answer. The issue here is that there are 5 or 6 questions on this table, and their reasoning is the same on all of them. I recall working those tables before with no problem (while doing their other practice exams).
Am I losing my mind, or have they lost theirs (or both maybe)?
