May fire sprinkler coverage for an NFPA 13 system be omitted from inside an air shower?
Are there any square footage standards that would apply, or any other "exceptions" that would allow omission? This is in a large industrial factory with hazardous materials. The inverse question would be...is sprinkler coverage required inside an air shower? Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe

NFPA 13 Section 4.1 states protection is throughout unless there are exceptions. Closets, chases, and other smaller locations require protection within, so I don't see a code-based exception for omission.

I agree with Dan, you'll need a sprinkler here. Try the 'clean room' gasket concealed sprinklers if there is a hard lid in the area. That'd keep the air/dust from leaking above the ceiling.

Is your "air shower" a piece of equipment that will be installed in this facility? If its equipment, rather than a "constructed room," then an argument may be made to avoid the inclusion of sprinklers.

I do not agree with this answer as a whole due to we had to provide coverage in 77 of 6'x8'x7' high enclosed soundproof auditing booths that were side by side spaced about 6" apart and there was coverage above. I agree it was a total waste, but I suggest speaking with the AHJ.

The adopted scoping Code (e.g. IBC-2021) determines WHERE an automatic sprinkler system (ASPS) is required to be installed and the Reference ASPS Standard (e.g. NFPA 13-2019) prescribes HOW a building’s/structure’s ASPS is to be designed, installed, inspected, and maintained.

Not seeing any specific exclusion, I think you have to protect it unless you can get AHJ permission to go beyond code with the omission.

Also, keep in mind that air curtains or these clean air barriers are probably the sole ingress/egress path from a clean space.
