KITCHENWHOOD FIRE PROTECTION
KITCHEN FIRE SUPPRESSION SYSTEM
INTRODUCTION
The NAFFCO
Kitchen Fire Suppression System is specifically designed for the suppression of
fire in commercial kitchen cooking appliances, plenums, hoods and ducts. Each
system operates automatically or may be operated manually.
The system uses
a liquid chemical as its agent. The agent is a solution of potassium acetate
involving:
Ø The saponification of surface grease (turning it into combustion-resistant
soap).
Ø The cooling effect of water vaporization.
Ø The inheriting effects of resultant steam formation.
Ø The interruption of the chemical chain reaction of combustion.
AGENT SPECIFICATION
FETTEX
Fire
Extinguishing Agent for cooking oil and fat fires.
DESCRIPTION
FETTEX is a
special liquid fire extinguishing agent based on salt for fighting fires
involving cooking oil and fat in deep fat fryers and frying appliances.
PROPERTIES
FETTEX reacts
with hot, burning cooking oil or fat. When the fire extinguishing substance
hits the surface of the fire, the flames immediately subside. An effective fire
extinguishing, cooling blanket of foam forms which prevents re-ignition.
