The basic aspects of fire extinguishers

The fire extinguisher is one of the most useful products designed by man. This device has a critical role to play in saving lives of people and preventing damage to property. The extinguisher has the potential to douse small fires before they turn into raging infernos that are hard to bring under control. This simple looking device is a must not just for offices, but also independent homes and residential complexes. The presence of these fire protection gadgets in hospitals and hotels is also highly recommended. This hand held protection device is manually operated and sprays out agents that are capable of putting out the fire. The fire extinguishers came into existence at the start of the 18th century. The device which was designed by a noted chemist of that era, Ambrose Godfrey, was a very crude one and comprised of gun powder which caused the device to explode and spew the contents all over to douse the fire. However, since then there have been many changes to the design and functions of the fire extinguisher, ensuring that the extinguishers that are available today are easy to handle in case of fire emergencies. Today, there are many types of fire extinguishers available for consumers to choose from based on various factors. While one classification is based on the type of operation, the other is based on the type of agent that is filled into the cylindrical container. Though the primary colour of the cylindrical can is red, there are certain other colours such as blue, yellow, black and white that are used to draw stripes that identify the contents within the cylinder. The fire extinguisher is also classified based on the types of fires that they are capable of putting out. The cartridge operated and stored pressure fire extinguishers are the two types of fire extinguishers that are highly sought after today. While the stored pressure extinguishers are commonly used for residential complexes and homes, the cartridge operated extinguishers are used in industrial units. The stored pressure fire extinguisher uses nitrogen to douse the fire, whereas the cartridge operated alternative uses carbon dioxide. These extinguishers are further divided into cart mounted and handheld devices. The handheld fire protection device is highly portable since it weighs between 1 and 30 pounds (roughly from 500 grams to 14 kilograms). On the other hand, the cart mounted devices weigh over 50 pounds (20 kilograms). Though the fire extinguisher is a very important device that should be present in every building, there are certain laws that are stipulated by the local and national governments regarding its usage. If you are planning to buy fire extinguishers for your home, it is recommended that you check with the local fire brigade before making your choice. This will ensure that you stay well protected. It is no longer necessary to visit various retail stores to purchase this device since they are easily available online.
