Sprinkler, Foam and Gas Suppression Design

We provide specialised suppression engineering across NFPA 13, 16, 2001 and 12

Technical overview

Sprinkler, Foam and Gas
Suppression Design

Fire suppression only works when the agent is matched to the fuel. Water spreads a flammable liquid pool fire, it destroys the energised electronics it is meant to protect, and it reacts violently with a combustible metal fire. Effective design therefore begins with the hazard rather than the catalogue, so we start from the fuel, its geometry and fire growth rate, the value being protected and whether the objective is control, suppression or total flooding. We then engineer the matched system to code, providing sprinkler and water based protection to NFPA 13 at the correct design density and area of application, foam to NFPA 11 and 16 for hydrocarbon hazards, clean agent to NFPA 2001 for occupied electronic and control rooms, and carbon dioxide to NFPA 12 where its life safety hazards can be managed. We integrate detection, actuation and the water supply so the system performs as a whole and not as a set of isolated components.

Engineering process

Sprinkler, Foam and Gas Suppression Design workflow

Hazard Classification & Density Determination

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.

Sprinkler Type & K Factor Selection

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.

Hydraulic Calculation & Pipe Sizing

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.

Foam System Design (Where Applicable)

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).

Gaseous Agent Design (Where Applicable)

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.

ITM Programme & FM Global Alignment

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.
