In every structure, in whatever nation, fire extinguishers are a common sight. You may want to check out The Bronx Fire Extinguisher Inspection for more. However, only a few of us are aware of how to utilise it effectively. Even fewer individuals are aware of the many kinds of fire extinguishers and the various reasons for which they are employed. In a structure, many kinds of disasters may occur, the most frequent of which being a fire break out. As a result, it is critical that we have at least a basic understanding of an item that is so widely used.
What is a fire extinguisher, exactly?
It’s a gadget that’s used to put out tiny flames that don’t reach the ceiling and have gotten out of hand. It’s usually a cylindrical cylinder with an extinguishing chemical that’s manually released when a fire breaks out. Its primary purpose is to clear escape pathways in the event of a fire.
What’s the backstory about fire extinguishers?
A fire extinguisher as we know it today evolved from its first version, which was created by Ambrose Godfrey in the first half of the 18th century and was not portable but instead installed in a room. George Manby developed the progenitor of the modern extinguisher, which he named “extincteur” at the time. A portable container filled with potassium carbonate solution and compressed gas served as the basis for this extinguisher. As time passed, new types of extinguishers appeared, including soda-acid fire extinguishers, chemical foam fire extinguishers, carbon tetra chloride extinguishers, and ultimately the contemporary extinguishers that we see today.
What criteria should we use to choose an extinguisher?
The kind of fire determines which fire extinguisher to use. As a result, we have Classes A, B, C, D, and F. Depending on the cause and severity of the fire, it is usually classified into various classifications. Here are some specifics about each:
- Class A – Class A fire extinguishers are used to put out fires that have started on common materials such as cardboard, wood, and paper. These extinguishers have a numerical number that shows how much liquid they contain and how much fire they can put out.
- Class B – A Class B fire is one that is caused by oil, grease, kerosene, or other flammable liquids. The number on these extinguishers indicates the amount of fire space they can extinguish.
- Class C extinguishers are used to put out fires caused by electrical appliances, wiring, and circuit breakers. There are no numbers associated with them.
- Class D – This refers to fires produced by flammable chemicals such as salt, potassium, magnesium, and other similar substances. This is mostly used in chemistry labs.
- Class F – This is for fires caused by cooking oil and deep-fat fryers, which are often found in restaurant kitchens and food processing plants.
What is the best location for a fire extinguisher?
Fire extinguishers are often positioned in areas based on the kind of fire that may develop and how quickly it might cause damage. For example, in the event of a Class A fire, the extinguisher is positioned such that a person cannot travel more than 75 feet to reach the extinguisher. It is positioned no more than 50 feet away in the case of Class B.
