Fire extinguishers- the most popular yet highly questionable thing! They are an essential part of fire safety equipment that is mandatory in every primary. Also, it's one of the most important technologies for fighting early fires and can also control them before it spreads in the building.

This is why we will give you every minor detail about fire extinguishers and look at them:
  • First, The Type Of Extinguishers:
  • Fire extinguishers are of seven types:
  • Dry Chemical Fire Extinguisher:

These fire extinguisher services are used for various purposes, although they are not well suited for indoor fires. Also called as dry powder extinguishers, these are packed with chemicals and contain powder-based extinguishing agents. Also, these help in removing oxygen, and it's alter-chemical composition. These extinguishers work on Class A, B, and C fires by hindering the oxygen path and the fuel in the extinguisher.

Water-Based Fire Extinguisher:

These fire-extinguisher keeps fires away by taking the heating element from the fires. They work by separating the oxygen elements from its other elements and are best suited for Class A fires. Also, these extinguishers contain fires and cause the rapid cooling effect by reducing the amount of heat from fires.

Clean Agents:

Clean agents come with halogen agents and are used for extinguishing fires by blocking the chemical reaction. They also work by completely removing the head from the fire triangle. Just like water-based fire extinguishers, this is also effective in class A, B, and C fires.

Foam Extinguishers:

Best suited for class A and B fires, which are freely burning carbonaceous materials like paper, wood, fabrics, and other flammable liquids. These extinguishers are often water-based and are used with special additives.

They can be used for electrical fires if they are fired at a distance. The only glitch with these extinguishers is that they leave a residue that needs instant cleanup. Plus, they are more costly than other water-based extinguishers.

CO2 Extinguishers:

These extinguishers are packed with pressured carbon dioxide gases and thus leave no residue when used. You can use over fires like electrical fires and fires that are burning liquid.

This is why these extinguishers are ideal for office fires.

CO2 present in them works by blocking the path of fires and suffocating them, the reason they don't harm any electrical equipment and don't even cause a short circuit.

However, they get very cold when discharged from the equipment, and if these devices are not equipped with the frost-free swivel and double-lined can freeze fingers. In addition, CO2 extinguishers are expensive.

Cartridge Operated Dry Chemicals:

These help in warding off fires permanently by blocking the chemical reaction; they are effective in class A, B, and C fires.

Usage Of Fire Extinguishers:

Fires extinguishers should only be used on someone who is trained to do. However, these extinguishers should only be alarm has triggered, and you know the safe execution route. Nevertheless, the following technique help in brushing up your fire extinguishers course. It's a four-step process and is called a PASS:
  • P: Pull: Pull the pin of the extinguisher and break the tamper seal.
  • A: Aim: Always aim for low by pointing the hose or nozzle at the base of the fire. Also, don't touch horns, especially when you are using CO2 extinguishers as they get very cold, and your finger might freeze.
  • S: Squeeze: Squeeze the handle of the nozzle to release the agent from the extinguisher.
  • S: Sweep: Sweep from one side to side at the firebase i.e., fuel source until the fire is extinguished.

Fire Extinguishers Also Need Proper Maintenance:

While you should step to the visual and physical inspections, for visual inspections, you should check:
  • If the extinguisher is in your proximity
  • If it's in your reach
  • Whether or not the extinguisher is charged
  • Is the pin or seal is not broken
Fire extinguishers are not made to keep them under the sink; they are used to protect you from deleterious fires!
