Fire causes differ, and thus there is the need for having different fire extinguishers for different purposes. Since fire has several causes and each reason makes a fire be distinguished to classes so that different extinguishers are made for each. Due to the dangers, a fire can cause companies conduct proper research on how they occur and then come up with efficient fire extinguishing agents to kill fires before the property is destroyed. Therefore, we are going to discuss the different types of fires and then focus on wet fire extinguishing agent; how they have manufactured in a company of our choice and the fires which it is most applicable in extinguishing.
There exists the class A fires, these are ordinary fires from wood, cloth and plastics and thus the extinguishers meant for it are also not complicated in manufacturing, take for example carbon (iv) oxide. Then there are the class B fires. They are from flammable liquids. The liquid can be liquefied propane, butane or gasoline. Similarly, one is not expected to extinguish such fires using water due to the causative agent properties. Then there are the class c fires; they involve electrical equipment fires while class D involves fires from combustible metals.
Fire extinguisher includes the dry chemical, clean agent, carbon dioxide, water and foam, dry powder and the wet chemical. The latter is not old in the field of fire extinguishers, and it functions by heat removal from the fire triangle. It also prevents the re-ignition of the fire by creating a barrier a barrier in between oxygen and the fuel elements. The fire extinguisher is suitable for both class A and F class types of fire; classes F include fires caused by cooking oil and grease. ("Wet Chemical Fire Extinguishers’’).
In this article our company of choice is worlad ("Fire Equipment Australia’’), this is an Australian based company that manufactures fire products such as the different fire extinguishers we have gone through. The company has got one hundred and twenty-five years of experience in fire safety. It Provides services such as the supply of fire equipment and maintenance of fire systems and also offers large –scale fire suppression systems for mining, industrial and marine.
The wet chemical extinguisher is tested and also certified by fire governing bodies including BS BS7937 and EN. Taking the 260 model it has a capacity of six liters with a fire rating of 13A:75F. The weight is ten kilograms making it very easy to transport and also hung. It works under an operating pressure of 6.9 bars which is enough pressure to extinguish a raging cooking oil fire. Finally, the discharge on average is fifty. Now highlighting on the material released, it contains potassium acetate; it forms a fine mist which forms soapy foam (Miller and Media). The advantage of the frothy form is that it efficiently suppresses any steam or vapor and thus preventing fire reflashes.
The wet chemical system is efficient since when the sprayed liquid hits the burning surface, it reacts with the cooking oil producing foam which consequently cools the burning surface. Hence, the fire will not re-ignite this makes it very applicable in a house kitchen. However, the extinguisher is expensive and hence not every homeowner can acquire one not to mention that it only puts out class B and K fires.
