NFPA CWBSP Exam - Topic 1 Question 22 Discussion

Posted by Bulah on Nov 23, 2025 at 03:59 PM

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

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.

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.

I'm a bit confused about the temperature ratings; I thought it was 175F, but now I'm second-guessing myself.
QU
Quentin 9 months ago
I remember practicing a question like this, and I feel like 150F was mentioned as a common rating for similar setups.
OL

I think the minimum temperature for ceiling sprinklers in that scenario is around 135F, but I'm not entirely sure.
RO
Rolland 9 months ago
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.
CA
Carmen 9 months ago
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.
