One might suppose that water is the most widely used extinguishing agent because of its low cost and ready availability , relative to other conceivable liquids. However, it turns out that, quite aside from cost and availability, water is (NFPA, Fire handbook — theory of fire extinguishment)
Superior to any other known liquid for fighting the majority of fires
Water has a very high heat of evaporation per unit mass, at least ________ _________ as high as that of any other non flammable liquid
Four-times
Water is also
Nontoxic
Water may not be effective for
Flammable liquid fires
Water is not compatible with certain hot metals or certain chemicals. With fires in these materials, other agents may be used (NFPA, Fire handbook — theory of fire extinguishment)
Aqueous foam / Inert gas / Halons and dry chemical
Water may extinguish a fire by combination of mechanism, cooling the solid or liquid combustible, cooling the flame itself, generating steam that prevent oxygen access, and as a fog. While all these mechanisms may contribute to extinguishment, probably the most important is
Cooling a gasifying combustible
The two most common means of applying water are
A solid stream or spray from a hose / Spray from automatic sprinklers
Evaporation of water, caused by wood fires, produce steam that
Dilutes the flame, and reduces flame temperature
The principle application of aqueous foam agents is for fighting (NFPA, fire handbook — theory of fire extinguishment)
Flammable liquid fires
If the flammable liquid is lighter than water and is insoluble in water, then application of water would simply result in the liquid floating on it and
Continuing to burn
Foams are the primary tools for fighting fires that involve substantial quantities of
Petroleum products
If the flammable liquid is water-soluble, like alcohols,then the addition of sufficient water will
Dilute the liquid to the point where it is no longer flammable
If there is a deep pool of alcohol. rather than a shallow spill (NFPA,Fire handbook — Theory of fire extinguishment)
using an aqueous foam, would be a better extinguishment agent
Liquids or solids that are burning in difficult-to-access spaces, such as a room in a basement or the whole of a ship, we would best use
The foam is used to flood the compartment completely
Foam is used as a fire fighting tool because
It is much lighter than any flammable liquid / Water-bearing mater that can halt or prevent combustion / it floats on the liquid, produces an air-excluding, cooling, continuous layer of vapor sealing, water-bearing material
Foam is
Unstable air-water emulsion
Fire fighting foam is formed by various methods from aqueous solutions of specifically formulated foaming agents which create (NFPA, fire handbook — Theory of fire extinguishment)

Extinguish a fire primarily by dilution
The most commonly used inert gas (NFPA, Fire handbook — theory of fire extinguishment)

Some inert gases that are used in fire-fighting are
Nitrogen or stream / Helium or neon / Argon
On a volume basis carbon dioxide is substantially more effective than
Nitrogen
As of january 1, 1994, the global production of fire protection halons in many counties ceased because
Halon production has ceased because halons have deleterious effect on the environment / Scientific evidence has strongly linked halons and chlorofluorocarbons (CFC’s to the depletion of earth’s stratospheric ozone layer)
Halogenated extinguishing agents, or halons, are chemical derivatives of (NFPA, fire handbook — Theory of fire extinguishment)
Methane (CH4) or ethane (CH3 - CH3)
Dry chemicals provide an alternative to carbon dioxide or the halons for extinguishing a fire without the use of water. These powders which are 10 to 75-microns in size, are projected by an inert gas. Of the five types of dry chemicals in use only one is effective against deep - seated fires because of a glassy phosphoric acid coating that forms over the combustible surface. This chemical is’

A dry chemical nozzle, carbon dioxide, steam or a halon
The best agent for fires involving metal is/are (NFPA, Fire handbook — theory of fire extinguishment)
Helium and argon
In chemical fires the best method for controlling the fire is

Test 5.4 Question
Answer
Pressure maintenance pumps are often found on a sprinkler systems. These pumps operate automatically when there is a slight drop in pressure due to leakage in the system. They also come on when there is pressure surge. This pump restores the pressure in the fire protection system to the desired level. if the drop of pressure in the system is greater than the capacity of this pump, then the fire pump comes on.
