I have a question that stems from NFPA 318 (Protection of Semiconductor Fabrication Facilities), Chapter 11, Section 18.104.22.168.
22.214.171.124* Automatic sprinklers for cleanrooms or clean zones shall be installed in accordance with NFPA 13, and shall be
hydraulically designed for a density of 8.15 L/min·m2 (0.20 gpm/ft2) over a design area of 278.8 m2 (3000 ft2).
For a clean room 126.96.36.199 mentions 0.20 gpm/sqft density over 3,000 sqft design area. We're considering quick-response standard-spray sprinkler coverage under section 188.8.131.52. The client is requiring a double-interlock pre-action system, so under NFPA 13 184.108.40.206.5 the remote area must be increased by 30% without revising the density.
Can we omit the 30% increase in sprinkler operation under NFPA 13 220.127.116.11.3 since we are using quick response sprinklers?
