Specialised suppression engineering per NFPA 13/16/2001/12
Specialised suppression design covering sprinkler (NFPA 13), foam (NFPA 11/16), clean agent (NFPA 2001), and CO2 (NFPA 12) systems. We deliver hazard-appropriate suppression for hydrocarbon, electrical, electronic, and combustible-metal fires.
A practical, phased delivery approach — from gap assessment through operational embedding — built around your regulatory context.
Classify hazard per NFPA 13 / FM DS 3-26 — Light Hazard, Ordinary Hazard 1 / 2, Extra Hazard 1 / 2; determine design density (gpm/ft² or lpm/m²) per occupancy and storage configuration; align with FM Global Property Loss Prevention Data Sheets.
Select sprinkler type per application — standard response (5.6 K), quick response (5.6 K), ESFR (14, 16.8, 22.4, 25.2 K), CMSA (16.8 K); specify temperature rating (135°F, 200°F, 286°F, 400°F, 500°F+) per ambient and ceiling temperature.
Conduct hydraulic calculation per NFPA 13 — Hazen-Williams or Darcy-Weisbach formula, pipe schedule (Schedule 10 / 40 black steel, CPVC, copper); size pipes for design density + 30-min duration light hazard / 60 min ordinary / 90 min extra.
For tank farm / flammable liquid, design foam system per NFPA 11 (low-expansion AFFF / AR-AFFF) / NFPA 16 (foam-water sprinkler); calculate foam concentrate inventory per credible-worst-case fire duration; specify proportioning (around-the-pump, balanced-pressure).
For special hazards (control rooms, electrical rooms, archives), design gaseous suppression per NFPA 2001 (Clean Agent — Novec 1230, FM-200) / NFPA 12 (CO₂); calculate design concentration, hold time, room integrity per door fan test.
Design ITM programme per NFPA 25 — weekly visual, monthly fire pump test, quarterly main drain test, annual full-flow test, 5-yearly internal inspection; align with FM Global Data Sheet 2-81 and insurer HPR requirements.
