First the importance of fire fighting tactics. First tactic, use of water. The most effective way of removing the heat of a fire is through the use of water. There are many different ways to apply the water but the most popular and effective for smaller fires is the spray technique. For larger fires a straight flow seems more useful because it can drench the flames to put them out. One of the major benefits of water is that only a little bit is necessary in order to extinguish a particular fire. One of the major problems that fire fighters face with using water is that they must be able to make it rea

ch the fire which can be difficult in large building like skyscrapers or high rises apartment buildings. For effective water dispersement in these areas sprinkler systems can be a valuable tool. Sometimes a standpipe is attached to a sprinkler system this is helpful because it cuts down the length of hose necessary to reach the fire.

An important part of any firefighters job knows his apparatus. One of the major devices used is a fire extinguisher. Once again for different types of fires different types of extinguishers. For class A fires which consist of fires with wood, paper, rubber and plastic water extinguishers are normally used. However in some cases the ABC dry chemical extinguishers can be used. Class B fires are liquid fires which consist of flammable liquids and gasses. Class B extinguishers differ from class A extinguishers because they cut off oxygen to the combustion zone which helps cause a chemical reaction which reduces the fire. C fires add in the threat of electrical components whose danger can be reduced by using extinguishers with conductive properties. Finally class D fires involve combustible metals or metallic alloys. These fire extinguishers have to suppress the fire without reacting to it otherwise the fire will explode.
