Fire Suppression System For Exhaust Hood
Wet Chemical Fire Suppression System
In Singapore, it is under the SCDF Fire Code that ventilation system must be equipped with a fire-suppression system. Cooking is the leading cause of all restaurants building fires, according to the “Fire, Ambulance and Enforcement Statistics 2017 by SCDF”.
A fire-suppression system connects to the hood system and helps prevent fires from spreading. The piped system is activated by high heat or can be turned on manually to dispense a liquid-suppressing agent that extinguishes fires quickly.
