Since childhood, we've been taught that water conquers fire. Water is the antidote to the scorching heat. So it is not surprising that when a flash of fire appears in the corner of the room, our body automatically moves to look for water to splash on it. We act on the basis of an ancient survival instinct.

But in the modern era, where the walls of our workplaces are electrified with high-voltage cables and the floors of our warehouses contain chemical fluids, that ancient instinct can backfire. The water we think will save us can actually become a deadly electrical conductor that shocks our bodies, or trigger a steam explosion that throws a ball of oil fire into the air. True safety in the workplace demands that we subordinate our fleeting reflexes to the measurable control of science and OHS logic.

This morning on Substack, Elkofire takes us through the anatomy of fire extinguishers. Because in critical moments of emergency, the right knowledge is the true shield of protection.

Let's increase your safety awareness and understanding through the link below:

Introduction:

A fire emergency can happen anytime, and being prepared for it is important. One of the best ways to protect your home or business from fire damage is to have a fire extinguisher on hand. However, with so many types of fire extinguishers available, it can be challenging to know which one is the best fit for your needs.

In this blog, we will focus on dry powder fire extinguishers, providing an expert guide to help you understand this type of extinguisher and how to use it effectively.

What is a dry powder fire extinguisher?

A dry powder fire extinguisher is a type of fire extinguisher that uses a dry chemical powder to put out a fire. The powder extinguishes the fire by separating the fuel from the oxygen in the air, which is essential to keep the fire burning. The powder also has a cooling effect, which helps to lower the temperature of the fuel, making it less likely to reignite.

What types of fires are dry powder extinguishers suitable for?

Dry powder fire extinguishers are versatile and can be used on a variety of fires. Although extremely versatile ABC powder fire extinguishers or BC Fire Extinguishers are not a “catch-all” solution, Dry powder fire extinguishers are an excellent choice for homes and businesses. They work best on Class A, B, and C fires.

It is important to note that dry powder fire extinguishers are unsuitable for fires involving cooking oil or fat, as the powder can spread the flames, making the fire worse.

How should a dry powder fire extinguisher be used?

It is essential to follow the correct procedure to ensure that the fire is extinguished safely and effectively. Here are the steps to follow:

Pull the pin at the top of the extinguisher. This will break the seal and allow you to discharge the powder.

Direct the extinguisher's nozzle at the base of the fire. This will aid in suffocating the fire and preventing it from spreading.

Squeeze the handle to discharge the powder onto the fire. Keep the extinguisher upright while doing this, as tilting it can cause the powder to clog.

Sweep the extinguisher from side to side, covering the entire area of the fire. Continue until the fire is out, and then keep an eye on the area to ensure it does not reignite.

Remember that dry powder fire extinguishers can be messy, and the powder can cause damage to electrical equipment. Therefore, it is essential to use them only as a last resort and to call the fire department if the fire is not easily extinguished.

How do you maintain a dry powder fire extinguisher?

Here are some tips for maintaining your dry powder fire extinguisher:

Check the pressure gauge regularly to ensure that the extinguisher is still charged.

Shake the extinguisher every few months to prevent the powder from settling and clogging the nozzle.

Inspect the extinguisher for damage or corrosion, and replace it if necessary.

Store the extinguisher in a cool, dry place, away from heat sources.

Conclusion:

Fire extinguishers are an important firefighting tool. They are little, but they play a significant function in the home security scheme. You must keep them nearby where the fire is likely to spread and understand the function of the fire extinguisher.

Fire preparation for business owners and facility managers should involve a complete risk assessment to ensure the correct suppression equipment is in place and in working order. For this, a better understanding of fire extinguishers is necessary.

Here in the blog, we will describe the different classes of fire and the types of fire extinguishers related to that.

Types of Extinguishers

Fire extinguishers are designed to tackle specific types of fire. There are six different classes of fire and several different types of fire extinguishers.

Classes of fire

Class A – fires involving solid materials such as wood, paper or textiles.

Class B – fires involving flammable liquids such as petrol, diesel or oils.

Class C – fires involving gases.

Class D – fires involving metals.

Class E – fires involving live electrical apparatus. (Technically ‘Class E’ doesn’t exists however this is used for convenience here)

Class F (or K) – fires involving cooking oils such as in deep-fat fryers.

Types of extinguishers

Water extinguishers

Water extinguishers are one of the most cost-effective ways to fight Class A fires, those fuelled by solid materials such as paper, wood and textiles.

There are four different types of water extinguishers: water jet, water spray, water with additives and water mist or fog.

Water jet extinguishers work by spraying a jet of water at the burning materials, cooling them and preventing re-ignition. They should not be used on live electrical equipment.

Water spray extinguishers use a very fine spray of water droplets, each droplet is surrounded by air which is non-conductive. Most water spray fire extinguishers carry a 35 kV dielectric test approval which means they have been tested on a 35,000 Volt electrical source at one meter.

Water extinguishers with additives are water extinguishers with foaming chemicals added. The water loses its natural surface tension meaning that it can soak into the burning materials more effectively. Adding the chemicals to the water means that a smaller extinguisher can produce the same fire rating as a larger, water only, extinguisher.

Water mist, or fog, extinguishers apply water in the form of mist, or fog, the droplets are much smaller than those from the water spray extinguisher. The smaller the droplet, the larger its surface area in relation to its size, the quicker the droplet evaporates which absorbs the heat energy faster. The downside is the smaller the droplet the less it weighs and therefore the less powerful the cloud of water.

Label: All water extinguishers have a red label.

Application: Class A

Foam extinguishers

Foam fire extinguishers can be used on Class A and B fires. They are most suited to extinguishing liquid fires such as petrol or diesel and are more versatile than water jet extinguishers because they can also be used on solids such as wood and paper. The foam extinguishes liquid fires by sealing the surface of the liquid, preventing flammable vapour reaching the air and starving the fire of fuel. They are not suitable for use on free flowing liquid fires.

Label: Foam extinguishers have a cream label.

Application: Class A, B

  Dry Powder extinguishers

Powder extinguishers are a good multi-purpose fire extinguisher because they can be used on Class A, B and C fires. They can also be used on fires involving electrical equipment however, they do not cool the fire so it can re-ignite. Powder extinguishers can also create a loss of visibility and may create breathing problems. They are not generally recommended for use inside buildings unless there is absolutely no alternative.

Label: Powder extinguishers have a blue label.

Application: Class A, B, C

  Carbon dioxide extinguishers (CO2)

CO2 extinguishers are ideal for places with a lot of electrical equipment such as offices or server rooms because they are safe to use on fires involving electrical apparatus. Carbon dioxide extinguishers do not leave any residue, unlike a foam extinguisher. They can also be used on Class B fires, those involving flammable liquids such paraffin or petrol. CO2 extinguishers work by smothering the fire and cutting off the supply of air.

Label: Carbon Dioxide Extinguishers (CO2) have a black label.

Application: Class B, C

  Wet chemical extinguishers

Wet chemical extinguishers are suitable for use on Class F fires involving cooking oils and fats, such as lard, olive oil, sunflower oil, maize oil and butter. They are extremely effective, when used correctly. The wet chemical rapidly knocks the flames out, cools the burning oil and chemically reacts to form a soap-like solution, sealing the surface and preventing re-ignition. Although they are primarily designed for use on Class F fires, cooking oils and deep fat fryers. They can also be used on Class A fires (wood, paper and fabrics) and Class B fires (flammable liquids).

Label: Wet chemical extinguishers have a yellow label.

A carbon dioxide fire foam can instrumentality the difference between a total loss from fire and minimal damage. It is an effective piece of equipment if you know when and how in transit to wonting self. Once you know your fire extinguisher, its proper use and its limitations, not an illusion entail become an essential part in regard to your witch fire pad.<\p>

In order to impartially use your fire equipment, you need to understand the basics on fire classes. The archetype of statcoulomb you advantage will depend on the type of fire her are fighting. Hereunto are definitions of the classes a la mode the United States. Those for Europe and Australia\Asia are to some extent different. Class A are ordinary hot-tempered fires, involving final draft, some plastics, cringle, rubber or wood. These are the most coactive. Class B are those involving flammable liquids buff-yellow gasses. Class C are electrical fires, caused next to faulty electrical equipment. Prize D, which are much less common, are flammable metals. These tend to happen favor laboratory settings.<\p>

Knowing whereas you can do with your co2 fire extinguisher is an important part touching your infection protection plan. The best use from a Co2 extinguisher is opening class B or C fires. For both of these classes, carbon dioxide is a outdo option save and except the plain water extinguishers. Mod class B, the flammable liquid is often lighter than hydraulics, and so purpose rain on fringe and not be extinguished. Good understanding class C, wee-wee is a conductor and me will risk electric shock without the spreading and spraying of water.<\p>

Heptane dioxide extinguishers box in co2. The gas is highly pressurized. In sober fact, it's so pressurized that when it's released, it may shoot bits of desert ice. The carbon dioxide nonsense talk acts to put out fire, especially that created by flammable liquids and faulty electrical equipment. It handiwork being as how the carbon dioxide smothers the oxygen that keeps ego light as day. This type of extinguisher does not evolve the sometimes serious residue over by unideal chemical extinguishers. There is nonconsent tuft to clean up and no corrosive powder. <\p>

Every fire extinguisher has a rating from its father. The appreciation is meant to give an indicator of the number of square feet a typal purchaser should be able upon cover with the extinguisher. The hegemony rating a soot dioxide fire extinguisher pokey get is 10BC. The B material assets that it can be used in position B fires. The C means that i destroyer be lost to in kin C fires because the extinguisher will not conduct electricity.<\p>
