It is important to have a portable or transportable equipment used to destroy a small explosion by trying to direct a component onto it which helps to cool the burning materials, deprives the flame of oxygen or interrupts the chemical reactions taking place in the flame. Here’s why you must have a fire extinguisher handy and how to use it!

How to use a Fire Extinguisher?
There are several multipurpose fire extinguishers labeled as B-C or A-B-C. Many home renovation stores stock multifunctional fire extinguishers that cover Classes A through C. Caravanners must be aware of fire extinguishers for their caravan. A small explosion can benefit from the use of fire extinguishers. Consider making a checklist available to assist people in preparing using a fire extinguisher on a potential fire. Caravanners must have at least a little knowledge or idea on how to use a fire extinguisher. Below are the steps.
Remove the pin. Release the locking mechanism while holding the extinguisher with the nozzle pointing away from you. Set your sights low. Point the extinguisher at the fire’s origin. Slowly and evenly squeeze the lever. Swipe the nozzle side to side.
Facts about Fire Extinguisher
Numerous easy fire extinguishers are comparatively tiny tanks with hand pumps or compressed gas sources to propel water through a nozzle. Water may contain a wetting agent to make it work better against upholstery fires, an additive to create a foaming agent which functions like an oxygen barrier, or an antifreeze. Carbon dioxide is a popular propellant that is activated by removing the locking pin from the cylinder valve that contains the liquefied gas.
Ctesibius of Alexandria created a primitive hand pump for directing water at a fire around 200 BCE. Ambrose Godfrey, an English chemist, and C. Hoppfer, a French chemist, developed devices that used explosive charges to disperse fire-suppressing solutions. In 1817, English inventor Capt. George Manby invented a handheld fire extinguisher. Modern incarnations, which use a variety of chemical solutions, are essentially variations on Manby’s design.
Advantages and Disadvantages of Fire Extinguisher
Advantages of Fire Extinguisher are, simple to use and can quickly control or extinguish a fire. The liquids used are non-toxic. Gas is non-flammable and does not contribute to fires. Gas does not consume electricity. It has the ability to penetrate small surface areas. Gas is not harmful to one’s health and has no effect. It can effectively control or extinguish class A, B, and C fires. It is more effective than a fire extinguisher, foam, or co2. The production (fountain) can be controlled by a lever and it can only be used once. Its mechanism and metallic tools should not be burned nor be placed in a cold or freezing environment.
The disadvantages, it is unable to control and extinguish large fires. Its residue can cause damage to certain materials such as car engines, food and so on. The cylinder can be frozen if stored in a cool place. Its overall weight is 5.3 kg but it only contains 2.2 kg of gas. The contents of the gas are invisible and should be weighed on a regular basis to avoid a 10% deficiency. It is not necessary to remove fire types A, B, and D. Large fires cannot be controlled or erased.
In an emergency, you must have a quick access to a fire extinguisher. Make certain that nothing is impeding or limiting your ability to reach it. Many extinguishers have pressure gauges that indicate when the pressure is too high or too low. Check to see if the can, hoses, and nozzles are damaged, dented, or rusted. Remove any dust, oil, or grease from the extinguisher’s exterior. Some extinguishers must be shaken once a month, while others must be pressure tested every few years.
When going out for a caravan a fire extinguisher must always be with you, in case of an emergency. It is easy to use although can only be used once.
