INTRODUCTION
CLASSES of FIRE
CLASS A – Ordinary combustible fires are the most common type of fire. Wood, paper, textile, and plastics CLASS B – Flammable liquid or gaseous fuels such as gasoline, oil, butane, propane, & gas. CLASS E – Electrical fires are fires involving potentially energised electrical equipment.
THE COMPONENTS OF A SPECIAL HAZARDS FIRE SYSTEM
SUPPRESSION SYSTEM this is the system that will extinguish the fire: can be Water, Gas, Foam, or FirePro. The selection of the suppression agent will be done with the client, considering the risk, location, and compliance issues.

DETECTION can be smoke. heat, linear heat, infrared, Vesda, or any combination depending on risk design and location

CONTROL SYSTEM automatic or manual operation, are shutdowns required, is a delay required. Selection is based on the system design and the compliance required.

If you need assistance in determining the system design or compliance issues, ASK.

HOW IT WORKS
The fire tetrahedron is an addition to the fire triangle. It adds the requirement for the presence of the chemical reaction which is the process of fire.
Combustion is the chemical reaction that feeds a fire more heat and allows it to continue.

FIRE – formation of free radicals (O*,H*,OH*) during the chemical chain reaction of fire

AEROSOL PHASE I – before extinguishing process Inert gases (N2, H2O, CO2) carrying solid micro particles K2CO3
AEROSOL PHASE II – during extinguishing process – formation of K* radicals by the disassociation of K2CO3
FIRE IS EXTINGUISHED – reaction between radicals lead to formation of stable compounds (KOH, 2CO3)
