[All CWBSP Questions]

What is the minimum temperature rating of ceiling sprinklers in roll paper stored at 15 ft. (4.6 m) or less?

A100F (38C)

B135F (57C)

C150F (66)

D175F (79)

Show Suggested Answer

Suggested Answer: C

The minimum temperature rating for ceiling sprinklers in roll paper storage areas that are 15 ft or less in height is typically 150F (66C). This rating is selected to provide a buffer between the ambient temperature conditions and the activation temperature of the sprinklers, preventing accidental activation.

I feel B) 135F is the best choice. Matches guidelines.

I chose A) 100F. Seems too low for paper storage.

I agree, B) 135F feels right. Not too high.

Nope, definitely 135F, that's the standard.

Surprised it's not 175F, seems low for paper storage!

I thought it was higher, like 150F?

Haha, the answer is obviously B) 135F (57C). Anything higher and the sprinklers would just melt the paper instead of putting out the fire!

Hmm, I'm going to go with A) 100F (38C). Wouldn't want the sprinklers to go off every time someone lights a match nearby.

D) 175F (79C) seems a bit high, but hey, better safe than sorry when it comes to fire safety, right?

I believe the answer is 100F, but I might be mixing it up with another type of storage.

I'm a bit confused about the temperature ratings; I thought it was 175F, but now I'm second-guessing myself.

I remember practicing a question like this, and I feel like 150F was mentioned as a common rating for similar setups.

I think the minimum temperature for ceiling sprinklers in that scenario is around 135F, but I'm not entirely sure.

I'm a little lost on this one. The storage height is given, but I'm not sure how that impacts the temperature rating. Maybe I should try to recall some fire safety basics.

I got this! Rolled paper has a lower ignition point, so the sprinklers need to be rated for a higher temperature. I'm going with C) 150F.

Okay, let me see. Rolled paper is a pretty common storage material, so I bet the code has specific requirements for that. I'll try to eliminate the options that don't seem to fit.
