NFPA 13 is not entirely clear about this because obviously a trampoline should not be compared to a conference room table. Anytime an AHJ brings something like this up and NFPA 13 is not clear about it that’s when I hire a FPE to take a look at it and make an interpretation. This is just so the local AHJ has something to protect them just in case there is something such as a fire.
Mike Stewart Dog Walker That's a tough one, is it actually fixed in place? If not it could be considered as a non combustible obstruction, not fixed in place, thus not requiring sprinklers below - but that might be a stretch.
NFPA 13, 2019
9.5.5.3.2* Sprinklers shall not be required under obstructions that are not fixed in place, such
as conference tables.
The size at which obstructions become too large to ignore is typically 4 ft (1.2 m). This width is reduced in
Chapters 13 and 14 for CMSA and ESFR sprinklers. Paragraph 9.5.5.3.2 recognizes that some obstructions
larger than 4 ft (1.2 m), for example, a conference table, are not fixed in place and are not likely to have any
significant combustibles located beneath them. In such cases, additional sprinklers are not needed below
the obstruction.

Hello,
We have an indoor jump park where they put in a jungle gym with the netting all the way around it, the padded walkways are 4’ wide exactly. There are 2 slides on it, one 8’ wide and one 5’ wide. There is ceiling protection above it currently,
has anyone put sprinklers anywhere down inside of these? Having a hard time finding much information on it other than “if the local AHJ requires it”, but the local AHJ is worried, not mandating it so looking for a little direction.
Thanks,
Caleb
