Hello all,

Looking at taking the ICC Fire Inspector 2 Test. A question posed was this:

Using a commodity Class III and having a S-1, Option 1, a building that is 240 feet x 480 feet ; Curtain board depth is 6 feet; and storage height is 30 feet. Answer the following: What is the total number of vents required?

A. 5

B. 6

C. 7

D. 8

I'm having difficulty of this, can anyone lend a hand in figuring this out?
 
Is there a problem with the question?

Sq ft is 115,200

Looks like the ratio is 1/75
 
My guess is they are asking about the number of vents per draft curtain area. So, with a 8,000SF/75=106.67SF total vent area per draft curtain area.

Then I guess you're supposed to assume the minimum size vent (4'x4') which would mean 106.67SF/16SF per vent=6.67 vents, so round up to 7 vents required.

Lucky thing it wasn't fill in the blank, I'd have gotten it wrong since the question was worded so poorly relative to the answer they wanted.

Very good

Not a math type person
 
Based on the building area, storage height and commodity classification, IFC Table 2306.2 doesn't require draft curtains for high-piled combustible storage. Just one more problem with this question.

Correct again, did not read all the way across
 
Thank you! Their answer was 7 and I didn't know how they had arrived at that! Thanks again!
