You drink eat, you bathe in it, you clean with it. Water, the universal liquid, life giving, life sustaining, and when you really need it: life preserving. Before the technological advancements in fire fighting, the original fire fighting tool used by man is water. Despite the commercial sewage treatment plant diagram fire extinguishers making use of chemicals as its main components, the traditional fire douser is still used and in fact recommended for the most basic type of fires. Water fire extinguishers are manufactured and sold, packed similarly like its chemical counterparts.
With the Benefits Comes Some Danger
Given the good qualities of water, it may also be deadly in a blink of an eye. Just like leisurely swimming in a lake and suddenly getting terrible cramps that you panic and lose concentration that in an instant you are now drowning in the same body of water that you were just enjoying a few moments ago. The danger lingers with fire fighting as well. Today, there are two kinds of water dousers that are meant to put out different classes of fires.
The first type is the air-pressurized water fire extinguisher, which basically uses the simple principle and prowess of air pressure to shoot the water from the container to the flame, is recommended for Class A fires. Class A fires are those that are fueled by ordinary combustible materials like paper and wood. However, as water conducts electricity fairly well, the danger lies when due to the pressure from the container a handful of the water spewed may ricochet back to you from drenched plugged in electric equipment. Also, using this type for Class B, flames fueled by flammable liquids like gasoline, and Class C fires, caused by electric equipment, will be a very bad idea. You would be better off leaving the blaze rather than attempting in using the product as it will only worsen it.
The second type is the Water-Mist Fire Extinguisher contains pressurized nitrogen mixed with distilled water to spray a mist instead of shooting a strong stream of water. It is safe to use in cramped spaces with electric equipment without the hazardous risk of getting electrocuted in addition to being less messy than the first type. Also, this may be used to contain the earlier mentioned Class B and Class C blazes. The only downside though is that it does nothing for the simplest of the fire types, Class A.
Large Scale Fire demand decreases and supply decreases Fighting
While water fire extinguishers that come in canisters are obviously for small scale fire fighting and will be absolutely no match to an inferno that has already engulfed a whole hose, then it’s time to bring out the big guns. The best bet here is to use a fire hose reel. It is what is being used by the professionals. Imagine the nuisance of having to fight a conflagration with hundreds of those containers?
