Combatting Fire With A Foam Fire Extinguisher: The Definitive Guide

Do you know it is essential to ensure your home and workplace is prepared with the right type of fire? Well, fire safety is very important as flames do not care what your race or sex is, how much money you have, what your job title is, or your popularity. Wondering how to keep your surroundings safe from fire? Well, using a foam fire extinguisher can be the difference between a minor fire and catastrophic devastation.

Every day, fire hazards destroy many homes and businesses throughout the world, and Ireland with no exception. Besides causing damage to property, fire can also lead to severe injuries and death. Having a foam extinguisher to combat fires that involve flammable liquids and solids like petrol, wood or paper is thus essential. Be it a school, hospital, or office environment, having the right extinguishing agent can be the key to fighting a fire.

Here’s all you need to know about foam extinguishers.

How To Identify A Foam Fire Extinguisher?

Fire extinguishers are differentiated not only by their names, but also by their coloured labels. Foam extinguishing agents have a red body with a cream-coloured label around the top of the tank with ‘foam’ marketed prominently on the front just above the operating instructions. Make sure you do not confuse these with water mist extinguishers – a relatively new variety that has a white band around the top of the tank.

A foam fire extinguisher can be identified even by looking at the description label that’s imprinted on the red tank. Check if the label includes:

  • • Type – Foam
  • • Use instructions
  • • Size – 9.0L is the most popular size
  • • Accepted materials for the use

 
What Are The Salient Features Of Foam Extinguishers?

  • • Highly portable
  • • Easy maintenance
  • • Rechargeable
  • • Effective on Class A and Class B flames
  • • Available in cartridge and stored pressure models
  • • Come with a steel cylinder, all-metal valves, and a nozzle

 
Which Types Of Fires Can These Extinguishers Fight?

It is a type of fire extinguisher that is very proficient in fighting two kinds of fire. These two types include:

  • •Class A

Flames are caused by ordinary combustible materials including paper, wood, cloth, plastic, and rubber.

  • •Class B

Flames are caused by various flammable liquids like diesel, petrol, and spirits. However, it is worth noting that Class B fires do not include flames started by kitchen fats and oils.

How Are Foam Extinguishers Classified?

The various types of foam extinguishers are:

  • • Alcohol-resistant film-forming fluoro protein (AR-FFFP)
  • • Alcohol-resistant fluoro protein foam (AR-FP)
  • • Regular protein foam (P)
  • • Fluoroprotein foam (FP)
  • • Film-forming fluoro protein (FFFP)

How Do They Work?

Foam extinguishers can combat Class A and Class B fires by covering the offending area in a thick foam blanket. Once it is directed to the fire, the foam floats on top of the burning liquid and starts diminishing the reaction between the fuel surface and flames. The smothering qualities prevent the fire from reigniting and seals off oxygen from reaching the fire while cooling the source of fuel.

Where Are These Most Suitable For Use?

A foam fire extinguisher is most ideal for hospitals, office environments, schools, and other locations where organic materials like grass or wood play a vital role in the landscape. Some of the other areas where these extinguishing agents can be used are- garages, petrol stations, oil refineries, workshops and small industrial locations.

Final Words:

The fire extinguisher is a wise investment for every home and workplace. And if you use flammable liquids routinely or store them in your place, opting for a foam extinguisher can be a better and economical option. Time to prioritise fire safety!
