[All CWBSP Questions]

What is the required density for a warehouse with 10 ft (3 m) deep multiple-row racks without an in-rack sprinkler

system that contains a nonencapsulated storing Class IlI commodity on wooden pallets and has a storage height of

18 ft (5.4 m) and 8 ft (2.4 m) aisles, and is using standard, ordinary temperature sprinkler heads?

A0.25 gpm/ft2 (10.2 mm/min)

B0.33 gpm/ft2 (13 mm/min)

C0.44 gpm/ft2 (17.9 mm/min)

D0.52 gpm/ft2 (20.8 mm/min)

Show Suggested Answer

Suggested Answer: B

For a warehouse with the described characteristics, a design density of 0.33 gpm/ft is a common requirement to ensure adequate protection for Class III commodities on wooden pallets, taking into account the storage configuration and commodity type.

Wait, is it really that low? I thought it would be higher.

I feel like the answer is definitely not 0.25 gpm/ft². I think it has to be at least 0.33 gpm/ft² or higher for that storage height and commodity type.

I’m a bit confused about the aisle width affecting the density. I thought wider aisles might lower the required density, but I can't remember the specifics.

I practiced a similar question, and I recall that for nonencapsulated Class III, the density usually goes higher than 0.25 gpm/ft². Maybe 0.44 gpm/ft²?

I think the density might be around 0.33 gpm/ft², but I'm not entirely sure. I remember something about Class III commodities needing a bit more coverage.

Okay, I think I've got this. The key factors are the storage height, lack of in-rack sprinklers, and the ordinary temperature sprinkler heads. I'll work through the density calculation step-by-step to arrive at the correct answer.

Hmm, I'm a bit unsure about this one. There are a lot of specific details to keep track of. I'll need to review the fire code requirements for this type of warehouse configuration to make sure I select the right answer.

This looks like a pretty straightforward fire safety question. I'll need to carefully consider the details provided about the warehouse setup, storage height, and sprinkler system to determine the required density.

I'm leaning towards 0.33 gpm/ft2 (13 mm/min) as well, but I can see why 0.44 gpm/ft2 (17.9 mm/min) might be necessary for safety.

That's a good point, the type of commodity could definitely impact the required density.

I disagree, I believe it should be 0.44 gpm/ft2 (17.9 mm/min) due to the type of commodity being stored.

Trick question! The real answer is 42 gpm/ft2 - just kidding, of course it's C. Sprinklers are no joke, people.

I think the required density is 0.33 gpm/ft2 (13 mm/min) because of the height of the racks.

I think the answer is C. The key details are the storage height, rack depth, and lack of in-rack sprinklers, which suggest a higher water density requirement.
