Microbrewery + Commercial Kitchen MEP — NFPA 96 + 17A + UL 300 + ISO 22000 + FSSAI

A 1500 m² Indian microbrewery with attached 100-cover restaurant needs ₹55 lakh kitchen MEP + ₹40 lakh brewery process MEP. Type I grease hood at 4000 CMH exhaust + 3400 CMH MUA per NFPA 96 + ASHRAE 154; UL 300 wet-chemical fire suppression; 16-gauge welded SS-304 grease duct in rated shaft. Fermentation cellar needs > 5000 ppm CO2 alarm + 12 ACH exhaust interlock + Class 1 Div 2 electrical. Three failures fire-NOC inspectors catch: grease duct alongside HVAC supply duct, make-up air below 85 % of exhaust, missing CO2 monitoring in brewery cellar despite IS 660 + OSHA 1910.

Brewery + commercial kitchen MEP — what makes it different

Microbreweries + commercial F&B kitchens are the most hazardous-occupancy commercial spaces below industrial — combining steam (10-30 kg/hr from mash + boil), high temperature (kettle outer 80°C + flame burners), CO2 generation (fermentation 1.4 kg CO2 per kg sugar), grease vapour (kitchen fryers), and live ignition sources. NFPA 96 + NFPA 17A + NFPA 70 Article 500-505 + ISO 22000 + Indian FSSAI + state excise (for brewery alcohol) all apply. Most Indian Tier-1 microbreweries (1500 m² + 5000 L brewhouse) under-spec CO2 monitoring + grease-duct fire-suppression.

MEP scope — 1500 m² microbrewery with attached 100-cover restaurant

Three F&B MEP failures fire-NOC inspectors catch

1. Grease duct in shaft with normal ducting — NFPA 96 requires grease ducts in a dedicated rated shaft with 50 mm air-gap from combustibles + 16-gauge welded SS. Indian projects routinely run grease duct alongside cold-air supply duct — failure mode is grease-residue ignition + fire travel along the supply path.
2. Make-up air below 85 % of exhaust — Type I hood exhaust at 4000 CMH needs MUA at 3400 CMH minimum. Indian projects often size MUA at 50 % to “save HVAC capacity,” depressurising the dining area + pulling smoke from kitchen-of-origin into seating. NFPA 96 §8 + ASHRAE 154.
3. CO2 alarm missing in brewery cellar — fermentation generates 1.4 kg CO2 per kg sugar; a 5000 L batch produces 200-250 kg CO2 over 7-14 days. Without 5000 ppm alarm + 12 ACH exhaust interlock, workers entering the cellar face asphyxiation risk. IS 660 + OSHA 1910 + state excise rules require this; rarely installed at India microbreweries.
