A portable fire extinguisher is a device that can be carried to a location where a fire has broken out and used to extinguish it. It is designed to be easy to use and comes in a range of sizes and types, depending on the type of fire it is intended to extinguish.
The most common types of fire extinguishers use water, foam, dry powder or carbon dioxide as the extinguishing agent. They work by suffocating the fire, cooling the flames or disrupting the chemical reaction that is causing the fire to burn.
It is important to understand the different types of fire extinguishers and how to use them correctly, as using the wrong type of extinguisher or using it incorrectly could be dangerous and make the fire worse.
