A spark of fire could destroy even a castle. Fire is one such dangerous element of the five great elements of life. Each of the elements is dangerous and the fire is one of the most dangerous elements. Fire is usually put off by water and it has been the method followed for a very long time. But then extinguishers were found to put off the fire. Extinguishers are in a variety that it is used based on the source of the fire. The extinguishing agent in each extinguisher supports setting off the fire based on the usage. Some extinguishers are meant to be used for fire out of paper, wood and plastic. Likewise, every source of the fire has a particular agent that could set the fire off.

What is a Fire Extinguisher?

In general, a fire extinguisher is an active fire fortification device used to extinguish or regulate small fires. It is not advisable to use on an out-of-control fire, such as one that has reached the ceiling; it risks the user or else requires a fire crew’s expertise. A fire extinguisher consists of a cylindrical pressure vessel containing an agent that could be discharged to extinguish a fire. Fire extinguishers that are manufactured with non-cylindrical pressure vessels also exist but are less common in usage.

There are two important categories of fire extinguishers:

• Stored-Pressure: The stored pressure has the expellant stored in the same chamber of the firefighting agent. Different propellants are used depending on the agents used. Nitrogen is usually used with dry chemical extinguishers, whereas water and foam extinguishers use air. Stored pressure fire extinguishers are the standard type of extinguishers.
• Cartridge-operated: these extinguishers have the expellant gas in a separate cartridge that is pierced before discharge, letting open the propellant to the extinguishing agent. This is not as common and used primarily in industrial fire areas, where they have a higher-than-average use.
