Wet Chemical Suppression System

A wet chemical system is the most commonly used fire suppression system to extinguish cooking oil fires. It is the primary source of extinguishing kitchen fires. The wet chemicals suppress fire by a process called saponification.

Open flames, red-hot cooking surfaces, and a heavily grease laden environment combine to make the modern commercial kitchen a potentially dangerous fire hazard. Kitchen fires spread quickly and have proven to be very difficult to extinguish, making them the leading cause of structural fire damage. Protecting the modern commercial kitchen from the ever-present danger of cooking oil & grease fires is the reason why the wet chemical suppression system is needed.

Under Chapter 7 of the Singapore Civil Defence Force, it is a compliance to have the wet chemical system installed at the Kitchen Exhaust Hood for certain F&B. For more information, please click here.
