Why is water such an effective fire extinguishing agent?
The reason water is such an effective extinguishing agent is because of its low cost, effectiveness and general availability. The physical properties of water mean that it is an effective combatant of all three sides of the fire triangle. These sides are the independent entities of oxygen, heat and fuel.
Why does water slow down the growth of a fire?
It is a well-known fact that water will slow the growth of a fire, and this can be written as a simple equation to illustrate the combustion process. Examining this relationship, it may be concluded that the control of fire is dependent on the ability to reduce one of the three components required by the combustion process.
Why is steam used as a fuel in a fire?
Because water expands so drastically when it turns to steam, the air becomes diluted with steam, which results in the displacement of the oxygen molecules by water vapour molecules. This reduces the amount of oxygen available to the fire and therefore helps to control the combustion process
What must the pattern of a solid fire stream maintain?
The pattern must be compact enough for the water to reach the burning material. D. The pattern must maintain its shape at least 50 percent of the reach of the fire stream. The pattern must be compact enough for the water to reach the burning material. 27. How may gravity, friction of air, and wind act on a solid fire stream? (951) A.
