Are the requirements for sprinklers in an 'Extraction Booth' the same as a 'spray booth'?
I have a customer looking to add wet pipe coverage to their new 'solvent extraction booth' which appears to be the same as a paint spray booth. The customer is claiming that the AHJ told them that there is no requirement for a separate riser as it's not technically a paint booth.
I can't find any supporting documentation of this in any NFPA standard. The closest example I can find is a paint spray booth which appears to require a dedicated riser no matter what.
Anybody have any experience with this?
Thanks in advance.
