Fire Triangle
Flames need fuel, oxygen and heat in order to burn which is called as Fire Triangle. Fire extinguishers are designed to remove one of these elements by applying an agent that either cools the burning fuel, or removes or displaces the surrounding oxygen.
The Basic Concept of Fire Control
Removing Heat (Cooling) - Heat can be removed by the application of a substance which reduces the amount of heat available to the fire reaction.
Removing Fuel (Starving)- Without fuel, a fire will stop. Fuel can be removed manually, by mechanically or chemically removing the fuel from the fire.
Reducing Oxygen (Smothering) - Without sufficient oxygen, a fire cannot begin, and it cannot continue. With a decreased oxygen concentration, the combustion process slows.
Fire Prevention System In A Building,
i. Active Fire Protection
ii. Passive Fire Protection
Active Fire Protection (AFP),
Active fire protection (AFP) is an integral part of fire protection. AFP is characterized by items and/or systems, which require a certain amount of motion and response in order to work.
Passive Fire Protection (PFP)
Passive fire protection (PFP) is an integral component of the three components of structural fire protection and fire safety in a building. PFP attempts to contain fires or slow the spread, through use of fire-resistant walls, floors, and doors.
