Full Fire Fighting & Fire Protection Course - (Part 8)

 

                    In this full series of Fire Fighting and Fire Protection, We will learn about Fire extinguishers and all the different types of Fire Extinguishers that are available.

These are devices that are designed to put out fire. Their purpose is two-fold. First, they protect people and property from being harmed or damaged due to the spread of fire. Second, they prevent fires from spreading from one area to another and endangering nearby structures. Most of these items have some sort of container, which holds the gas that is injected into the air. If water cannot reach the fire and does not stop its progress, then the fire extinguisher may help to save lives and damage.

Fire extinguishers use a liquid called “extinguishing agent” to fight a fire. It is delivered into the atmosphere by a pressurized spray bottle. When sprayed onto a flame, it mixes with the oxygen in the air and produces an inert gas that absorbs the oxygen surrounding the flame. Therefore, the burning fuel stops and the flames die down.

There are many types of fire extinguishers, including those that work on different fuels. Inhalants extinguish fires that burn flammable liquids. A chemical extinguisher works by putting out fires caused by hot gases, chemicals, or electricity. An automatic sprinkler system helps to provide protection by automatically detecting fire conditions and activating fire suppression equipment.

You should always test your fire extinguisher before using it. Make sure that it is fully charged and ready to go. Check to make sure that it comes with a manual. Look at the label to find how long the manufacturer claims that it will last. Also find if the device is intended for commercial or residential use; you need to get the right type.

Always follow the instructions provided by the manufacturer. Never attempt to replace or fix the nozzle yourself. Doing so could cause serious injury or even death. Even if you think you know what to do, ask someone who knows about fire safety.

A fire extinguisher is a device designed to put out a small amount of fire. You would use it if you have accidentally started a small fire inside a home or building. Fire extinguishers work by spraying pressurized water, carbon dioxide, dry chemical, foam or powder into the flames. A regular household fire extinguisher contains foam and is not suitable for putting out fires inside a house. Use a fire extinguisher only if you can get close enough to the point where the fire is located. If you remove any coverings or obstructions, then you may not be able to reach the fire for the purpose of using a fire extinguisher.

Fire extinguishers are devices that function to stop the spread of fire. These devices use substances like water or carbon dioxide to help put out fires. They utilize these chemicals to create a controlled reaction that helps put out the flames. There are two types of extinguishers; those that work on the principle of water and those that work on the basis of carbon dioxide.

Water extinguishers are generally known as a wet chemical system. In contrast, CO2 extinguishers work on the basis of dry chemistry. Wet extinguishers work by releasing water onto the fire causing cooling effect and thus stopping the fire. Dry extinguishers work on the principle of Carbon Dioxide (CO2) and release the gas to the atmosphere where it dissolves in water in the air to form a mist that cools down the surrounding area. Dry extinguishers work only if the fire is burning at high temperatures.

There are various types of fire extinguisher systems available in the market. A typical home requires both types of extinguishers. Water extinguishing systems work best in small spaces such as homes and offices while dry extinguishers work efficiently in larger spaces like warehouses, factories and power stations. Dry extinguishers are not suitable for extinguishing fires inside buildings. However, they are useful in certain situations.

A typical residential fire extinguisher system consists of a CO2 extinguisher, an AC powered pump, a foam generator, and a container filled with water. When activated, the AC powered pump sprays the water through a hose that reaches the nozzle of the CO2 extinguisher. Once the water strikes the fire, the foam generated by the foamer forms millions of tiny bubbles containing the CO2. As the CO2 comes in contact with the hot fire, it begins to dissolve in the water forming a thick and dense foam. The fire is thus extinguished effectively.

The type of extinguisher used should depend upon the size of the space involved. If the space is small, then the use of a water extinguisher is recommended. However, if the room is bigger, then using a dry extinguisher would be more appropriate. Portable CO2 extinguishers are ideal for extinguishing fires in rooms that have low ceilings.

Types of Fire Extinguishers

A fire extinguisher can mean many different things to different people. But what you need to know is how to use them correctly.

First off, if you have a small kitchen fire, it might not be a big deal. But if you're making soup or baking bread, then you'll want to turn the stove off immediately. You should never try to put out a large fire yourself. Instead call 911 right away! If your house is on fire, get everyone out of the building and then call the fire department. Keep reading to learn about types of fire extinguishers.

Gasoline Fire Extinguisher

The gasoline fire extinguisher is the most commonly used type of fire extinguisher. To operate one, pull back the handle until the nozzle is exposed. Spray the liquid onto the flames and wait for a few minutes before repeating. Never throw water directly at a flame. It could explode.

Water-Based Fire Extinguisher

To operate a water-based fire extinguisher, hold the nozzle pointed downward and spray water onto the burning object. Wait for a few seconds and repeat. Never drop water straight down onto a flame. It will cause an explosion.

Flash Fire Extinguisher

You can use a flash fire extinguisher indoors to put out flaming candles, small fires, or electric sparks. Always aim the extinguisher at the source of the fire. Hold it steady until the fire stops burning. Don't point the extinguisher at anything else, such as furniture or flammable objects.

Electric Shock Fire Extinguisher

When using an electric shock fire extinguisher, place the device between two grounded surfaces to create electricity. Then press the button to release the charge. If necessary, hold the unit over the flames and again press the button to finish the job.

Wet chemical

Wet chemical fire extinguishers use a combination of water and chemicals to put out fires. These fire extinguishers are the safest type of fire extinguisher. However, because they require electricity, they aren't always effective at putting out a small fire.

Dry chemical

Dry chemical fire extinguishers work much like wet chemical extinguishers except that they don't contain any water. Instead, they contain dry chemicals that produce carbon dioxide (CO2) gas when exposed to oxygen. The CO2 gas fills surrounding air pockets and prevents oxygen from reaching the flames. Using dry chemical fire extinguishers can be tricky though because if the liquid is not applied properly, it could cause burns.

Carbon Dioxide fire extinguishers

Carbon dioxide fire extinguishers work just like dry chemical extinguishers only instead of containing chemicals, they contain dry ice.

 Electrical Fire Extinguisher

An electrical fire extinguisher is one of the most versatile types of fire extinguishers on the market today. There are many different sizes and shapes available for you to choose from. An electrical fire extinguisher consists of two parts: the container (the body) and the hose (an extension). The hose usually comes equipped with a nozzle at both ends to get the right amount of liquid sprayed onto the fire. You may find yourself using either water or chemical-based water mixtures.

Class 1 Fire Extinguisher

Class 1 fire extinguishers use dry powders, granules, or tablets that work by absorbing moisture into the surrounding air. These kinds of extinguishers are popular for home use. When activated, they emit a cloud of particles that cover any flames and prevent them from spreading. Use these extinguishers carefully; if not used properly, they could cause serious injury to people and animals nearby.

Class 2 Fire Extinguisher

A class 2 fire extinguisher is similar to a class 1 extinguisher. However, their liquid content is mixed with carbon dioxide gas, making it less dangerous than a class 1 extinguisher and easier to handle. This type of extinguisher can still be harmful to people and pets nearby.

Class C Fire Extinguisher

This kind of extinguisher contains a mix of chemicals that spray water onto the flame while releasing carbon dioxide. Unlike a class B extinguisher, a class C one does not give off a powdery substance that covers the flames.

Class D Fire Extinguisher

These are the most powerful fire extinguishers and can be found in commercial settings. A class D extinguisher releases pressurized steam and smothers the flames instantly. Though this creates a lot of steam around the area, it makes breathing difficult and causes potential damage to equipment nearby.

Class E Fire Extinguisher

In comparison to class D extinguishers, class E ones have a lower pressure and release a cool mist. The cool mist keeps the temperature down in the room and helps suffocate the flames. Class E extinguishers make great classroom devices because of their low noise level, small size, and ease of handling.

Class F Fire Extinguisher

If you're looking for something that works best indoors, then a class F fire extinguisher might be just what you need. A class F extinguisher uses compressed inert gas to create a fine mist that puts out fires by smothering rather than heating or blowing. A class F extinguishing agent works well in kitchens, garages, warehouses, industrial facilities, or anywhere else where it's hard to get access to water.

Portable Fire Extinguishers

Portable Fire Extinguisher is defined as an extinguisher that is not permanently affixed to any particular apparatus or equipment. Portable fire extinguishers are the ones that are mounted on fire trucks, and therefore they are called truck-mounted fire extinguishers. Truck-mounted fire extinguishers are mounted on the back of fire trucks and work by pumping water. Other than being mounted on the back of a fire truck, these fire extinguishers have no special features. However, some fire extinguishers have been built to be placed on top of fire hydrants. These extinguishers are generally known as fire hydrant fire extinguishers. There are various types of fire extinguishers that people use to fight fires. These extinguishers can be categorized based on their composition. The most commonly used type of fire extinguisher is the dry chemical fire extinguisher. Dry chemical fire extinguishers are composed of either carbon dioxide or halon gas. Halon fire extinguishers are widely used today. People who want to buy fire extinguishers should consult professionals before buying them. Experts recommend that people buy fire extinguishers that meet NFPA standards.

Mobile Fire Extinguishers

A mobile fire extinguisher is a firefighting tool that is designed to be easily transported and stored. These devices have become increasingly popular, especially in recent years due to their portability and ease of use. They are able to provide quick access to a wide range of chemicals including water, foam and dry chemical agents.

The basic components of these tools include the container they are built around, a hose, nozzle and trigger mechanism. They have been widely adopted amongst firefighters across the globe. However, some people may not know what exactly these items do and how each works before they go out of the box. Let’s take a closer look at the parts and features of a typical mobile fire extinguisher.

Container

It is the container that houses the contents of the device. It is generally constructed from metal, plastic, wood, glass or even ceramics. Depending upon its size, shape, design, material type and durability, containers could be classified as either fixed-position or portable. Fixed-position types work best indoors where they don’t need to move around much while being deployed. Portable containers are ideal for outdoor use. They are smaller and foldable, making them easier to transport to different locations.

Hose

A hose is a flexible tube used to deliver pressurized fluid, whether it is a liquid, gas or mist. In order to function properly, they should be made from durable materials that won’t break under pressure and high temperatures. Firefighters often use hose to direct streams of water towards a burning object. Hoses are usually made from durable thermoplastic materials such as polypropylene, nylon or PVC.

Nozzle

A nozzle is a specialized piece of equipment that is attached to the end of the hose. A nozzle consists of a housing that contains a valve that controls the flow rate of the fluid. It is connected to the hose via a threaded adapter. There are two types of nozzles; wet/dry and manual/automatic. Wet/dry nozzles allow the operator to control the flow rate manually, whereas automatic nozzles are pre-set according to the amount of chemical agent required.

Trigger Mechanism

A trigger mechanism is simply a lever that allows the user to activate the release of a predetermined amount of chemical agent. Its activation is triggered using either a hand or foot pedal. Using this method makes it possible for the user to make the necessary adjustments without having to physically pull back on the handle.

Automatic Dry powder Fire Extinguishers

Automatic dry powder fire extinguishers are designed to rapidly discharge a powdered chemical agent into a burning or smoldering fire without causing water damage to surrounding objects. Automatic fire extinguishing systems work based on the principle of the physics of combustion. When heated to a certain temperature, air releases oxygen atoms and combines with carbon and hydrogen atoms to create a gas called “oxygen”. In order to consume the oxygen in a flame, a gaseous substance is added to the air. If the mixture of air plus the gaseous substance does not have enough oxygen, then the flame will die out. In a typical house fire, there is plenty of oxygen, so the fire cannot burn. However, if smoke particles are present, they block some of the oxygen molecules. A fire extinguisher containing a powder that reacts chemically with the smoke particles causes them to combine with oxygen and release the blocked oxygen back into the atmosphere, thus restoring the supply of oxygen to the flaming site. These powders are known as “dry powder agents” as opposed to liquids that require mixing prior to use, which are termed “wet powder agents”. Dry powder agents are highly effective, inexpensive, and simple to operate. They can easily be applied directly to the source of the fire without mixing, and can be handled safely as their high reactivity makes them less toxic than liquid agents. Due to these advantages, dry powder agents are widely accepted as the preferred agent for suppressing fires in buildings and vehicles.

                        

                        A dry powder fire extinguisher is a kind of fire extinguisher that works using chemicals rather than water. A typical dry powder fire extinguisher consists of two parts: a cartridge containing the dry chemical agent and a mechanism that releases the powder at high velocity. When the powder comes in contact with a flame, combustion is inhibited and prevented from spreading further. Dry powder fire extinguishers are commonly used on fires involving flammable liquids, for example car engines, oil tanks, petrol pumps and gas cylinders. They are also suitable for small fires, including candles, cigarettes and cigars.

Dry powder fire extinguishers were invented in 1884 by American engineer George Westinghouse, who was working for Thomas Edison's company. He wanted a reliable method of dealing with fires that could be easily transported. In 1911, a dry powder fire extinguisher called "The Wizard", created by American inventor Joseph Kittinger became available commercially. It would go on to become the first practical non-water-based fire extinguishing device. Today, there are over 20 different types of dry powder fire extinguishers available for consumers.

Aqueous film-forming foam (AFFF) Extinguishers

Aqueous Film Forming Foam (AFFF) is a chemical agent commonly used in fighting fires on land and sea. AFFF is sprayed on the surface of burning material and causes rapid cooling, thus preventing further combustion. It is also effective at stopping electrical arcs.

1. Aqueous film-forming foams (AFFF) are designed to rapidly soak and coat surfaces and liquids, including combustible substances. These compounds are used to suppress fires using water-based extinguishing methods. However, they are not intended to prevent ignition or reduce combustion; rather, these agents are meant to suppress burning until a fire department arrives.

2. What does AFFC foam consist of?

The active ingredient in an AFFF is a polymer that forms a sticky gel, thus coating the surface area of an object. Once the surface is coated, no oxygen can reach the material below. When exposed to heat, the polymer breaks down and creates small bubbles, filling the void between each bubble. These bubbles act as a barrier to protect the underlying materials from further flame exposure.

3. What types of fires do AFFFs work best on?

AFFFs are effective at suppressing all flammable airborne liquids. In addition, they are able to control smoldering flames, which is helpful for extinguishing grease fires. However, their effectiveness relies heavily on how much time elapses before fire departments arrive.

4. How long does a typical AFFF foam last?

While foam generated with AFFFs is highly effective at soaking up fuel, the polymers break down after approximately 30 minutes. Therefore, the foam generated by an AFFF should only be used once to ensure complete coverage of the target surface.

5. Where can I find them?

An AFFF is a combination of two chemicals - ammonium nitrate and aluminum powder. Chemists who make AFFFs use proprietary formulas based upon different concentrations of these two chemicals to create optimal foam performance. To find out where to purchase AFFFs, check online directories for suppliers of professional services.

Aqueous Film Forming Foam (AFFF) is a type of AFFF agent that contains a high concentration of water-soluble surfactants, making them suitable for use in many applications where liquid AFFFs cannot be used due to environmental restrictions, toxicity concerns, etc. While they have many advantages over other types of foam agents, they do have some disadvantages. If not properly applied, they can cause serious damage to the environment. Also, if allowed to dry out, they become ineffective. Aqueous film forming foams (AFFFs) are chemical flame retardants designed to break down into harmless products upon contact with flames. They are often referred to as “water soluble” because they consist of two parts: a water-soluble polymer and a highly reactive chemical additive. When exposed to heat, the additive reacts with oxygen and breaks off from the polymer, leaving behind inert polymers that adhere to the surface of the burning material. Water then dissolves these polymer chains, releasing the active ingredient and helping to prevent further combustion. Aqueous film forming agents work well for combustible materials like wood, paper, plastic, metals, and textiles. 

Can Aqueous Film Formers Be Used In Fire Extinguishing Systems? 

Yes! Aqueous film forming foam extinguishers are commonly used in commercial settings like hotels, schools, and retail stores. They are great tools to help protect people from fires caused by candles, cigarettes, cooking grease, matches, lighters, incandescent bulbs, and electrical outlets. As long as the system remains fully wet, it will continue to operate without issues. However, if the system becomes dry, the foam will begin to burn and create toxic gases. 

How Much Do I Need To Use? 

You should use enough fluid to fill the tank to capacity. This means you need to measure the volume before filling it. Also, remember that it takes 1 gallon of AFFF per square foot of area that you want protected. So if your room is 10 feet x 15 feet, you would need 1 gallon of AFFE per 10 square feet, or 100 gallons. Keep in mind, though, that this is just a general guideline. You may encounter situations where the amount of space to be covered requires less or more than what is recommended above. 

What Type Of Equipment Do I Need? 

You will need a pump, hose, filter, mixing valve, and reservoir. You will also need a battery operated timer. These are inexpensive items that you can find online or at home improvement stores. 

What Is My Budget? Aqueous film-forming foams are generally priced between $10-$20 each. If you require multiple systems, however, prices go up significantly. 

Is There Any Other Special Considerations?

 Yes, there is. Make sure you choose a product that meets NFPA standards. NFPA stands for National Fire Protection Association. It is the leading professional organization dedicated to providing safe and effective solutions to fight fires. More importantly, make sure the system is tested regularly for leaks. If it does start leaking, stop using it immediately and call an emergency plumber. If you don't take action soon enough, you could end up causing even worse problems. Also, keep in mind that AFFEs are flammable themselves. Be careful while handling them. Finally, make sure you follow all safety precautions. That includes wearing protective gear, reading labels, and following instructions written on the container.

Water-Mist Type Fire Extinguishers

Water Mist Fire Extinguishers are used to put out fires caused by electrical equipment, candles, etc. Usually these types of fires are small and need a quick response. In some cases they need to be placed in hard-to-reach places. These extinguishers use water under pressure to spray and cool down any flames. Water Mist Fire Extinguishers should always be stored away from fuel, hot materials and flammable items.

A Water Mist Fire Extinguisher (WME) is a fire suppression device that produces a fine spray of water droplets at high velocity. When sprayed onto the surface of a flame or a smoldering ember, the water creates a layer of fog around the area to reduce oxygen supply and protect nearby combustibles from ignition. A WME may not always succeed in extinguishing fires, especially if the flames are deep inside the material being protected. In the case of a grease fire, for example, a WME may not have enough time to work properly.

Water Mist Fire Extinguisher types vary greatly depending on where they are intended to work. They are designed to put out fires caused by flammable liquids or gases. Water mist fire extinguishers are used to put out fires that may start by burning or exploding fuel tanks and boilers. These units have a mixture of water and air inside them. When a flame ignites something in the tank, the water mist becomes activated and mixes with the air and prevents the oxygen supply from reaching the flames. This causes the flame to go out. An advantage of these units is that they don't cause any damage to surrounding objects since they do not spray a liquid onto objects. Instead, they use only water. Another advantage is that these units don't require electricity to operate. Their design makes them portable and convenient to use anywhere.

Wet Chemical Extinguishers

A wet chemical fire extinguisher utilizes water to put out fires. The extinguishing agent comes in the form of chemicals dissolved in water. There are three types of wet chemical extinguishers: A) Dry Chemical (Dry Chemical): In a dry chemical fire extinguisher, inert gases act as a carrier gas and dissolve the fire suppressants. B) Halon 1301: Due to its high stability and low cost, halon has become the dominant fire suppression technology worldwide. C) CO 2 : Carbon dioxide is non-toxic as well as inexpensive. It is cheap, safe, and effective at extinguishing fires due to the fact that it absorbs oxygen present in air and thus deprives oxygen supply necessary for combustion.

Drench Fire Extinguisher

The drench fire extinguisher is a type of wet chemical fire extinguisher where the fire suppressant(s) is mixed directly with water on site before use. The suppressant(s) mixes with water to form a homogeneous mixture. A few minutes after mixing, the mixture enters the hose and travels to the burning area. Once the fire is extinguished, the extinguishing agents dissipate. The advantage of the drench fire extinguisher over the conventional wet chemical fire extinguisher is that the fire suppressant is not stored in a container and therefore is transported directly to the fire location, thereby reducing the risk of explosion and leakage of the fire suppressant. The disadvantage of a drench fire extinguisher system is that it requires a separate pump and storage tank for each application, and the operator must mix the suppressant with water onsite.

Foam Fire Extinguisher

Foam fire extinguishers are designed to produce foam by combining foaming agents with water. As water evaporates, the foam expands to cover the surface of the fire. The foam then suffocates the fire until water can reach the area to extinguish it. Foam fire extinguishers have two major advantages over other types of fire extinguishers. First, they do not require any special training once installed. Second, since the foam does not have any toxic components, it is safe to use around people and animals. However, foam fire extinguishers are expensive, bulky, and difficult to transport. They also cannot be used if the fire is in an enclosed space.

Gas Fire Extinguishers

Gas fire extinguishers work by applying a spray of pressurized liquid onto the fuel-air mixture. The fire suppressant coats the flames and prevents the flame's contact with oxygen. Because these extinguishers only deal with open flame fires, they are ineffective in dealing with smoldering fires.

Clean Agent Fire Extinguishers

Clean agents are the first choice for fire-fighting at home and work. The type of clean agent you use depends on the size of the fire, what materials are burning, how much time you have to put out the fire, and where the fire is located. Clean agent fire extinguishers may look different than regular types of fire extinguishers, but they work pretty similarly. When you need to use a clean agent fire extinguisher, follow these steps:

1. Check the label to make sure you're using the correct kind of cleaner for fires. You'll find the information about the cleaner right on the label. If you don't know what kind of cleaner you need, ask someone who does. Don't try to guess; it's best if you know exactly what you're doing.

2. Read instructions carefully before putting the cleaner down. Always follow directions closely. A lot of cleaners have special instructions written next to them. Follow those instructions carefully.

3. Make sure the cleaner container is sealed tightly. Keep the lid on until you're ready to use it. Don't just set it down somewhere and forget about it. That could cause the contents to spill.

4. Remember to keep the cleaner close at hand. Always have it near you in case you get a fire emergency. If you leave it somewhere else, it might not save the house or building if a fire breaks out.

5. Try to control the fire as soon as possible. Don't wait until the flames reach full intensity. Take action immediately! Your goal is to prevent the fire from getting worse.

6. If the fire is small, use a dry chemical fire extinguisher. Never use water, foam, or carbon dioxide.

7. After you've put out the fire, throw away any containers that still have cleaner inside them. You should never reuse a dirty container.

Clean agents are chemical compounds that help stop fires. There are many different types of clean agents out there, so they are not all created equal. In order to determine what type of fire extinguisher you need, you should know how the fire is going to start. Then, look at the chemical composition of the cleaner to find the best fit for your situation.

Clean Agent Fire Extinguisher (CAFE) agents are chemical compounds that are able to destroy the oxygen content inside a burning object and prevent the propagation of flames. CAFE agents do not require direct contact with the flame, however they need to be placed in close proximity to the flame. Two major types of CAFE agents are 1-chlorobenzotriazole (CBT), and 2-amino thiazole (AT). CBT is more effective at containing fires than AT, because CBT is less hygroscopic than AT. In addition to these two compounds, some manufacturers make use of ammonium phosphates, alkylphosphonic acid esters, and/or dimethyl phosphate. Alkylphosphonic Acid Esters (APASE) are considered to have a moderately high effectiveness, but their lack of stability makes them impractical for general use. Dimethyl Phosphate (DMP) is known to degrade rapidly under acidic conditions; making the product unsuitable for use in wet environments.

CAFE agents work by reacting with free radicals formed by combustion, thus preventing further oxidation of flammable materials. When applied directly to a flame, CAFE agents produce carbon dioxide gas, water vapor, and hydrogen chloride vapors. All three products are capable of removing oxygen molecules from the air surrounding a fire. Because of this, CAFE agents are highly reactive towards combustion. Once a CAFE agent reacts with a free radical, it becomes inactive and cannot react again until its molecule is broken down.

The Clean Agent HFC227EA fire suppression system works by introducing inert gas (helium) into the air space around a fire. As soon as the fire starts burning, the He begins to fill the room, displacing oxygen and carbon dioxide. When enough mixture exists, it produces a physical barrier between the hot gases inside the flames and the surrounding area. The result is that the fire burns less fiercely and smoke levels drop significantly.

When a fire does occur, it's critical to act swiftly!

If you suspect a fire, get out immediately and call 911. Do not attempt to put the fire out yourself unless you have been trained to do so. In any case, avoid moving people or objects until a professional arrives. If possible, turn off electrical power. Turn off breakers at circuit panels and disconnect switches. Use dry chemical or mineral-based materials to eliminate sparks or open flame. Call your local fire department.

Clean agents are effective at suppressing fires in enclosed spaces up to about 15 feet wide and 60 feet long. You may need to use two systems if the fire is larger than this. To determine if the fire is contained by the Clean Agent HFC227-A System, follow these steps:

• Examine the flames and smoke coming from the building. Is the fire burning steadily? Or do you feel warm or cold drafts coming from the area where the fire started?

• Look at the temperature of the fire. Are the high temperatures dropping?

• Listen to the sound of the fire. Does it make a steady crackling noise? Or is there a loud boom?

• Check for smoke rising from the area where the Fire is occurring.

• Does anyone smell smoke?

Once you've determined the size of the fire, use the following guidelines to decide how many Clean Agent Systems you should install:

• 1 Clean Agent System per each 50 square feet of floor area in an open office

• 2 Clean Agent Systems per each 100 square feet of floor area of an administrative office

• 3 Clean Agent Systems per each 200 square feet of floor area

• 4 Clean Agent Systems per each 300 square feet of floor area or more

How To Use Clean Agent HFC227Ea Fire Extinguisher Device?

Before using the device, make sure you read the user manual carefully. Ensure that you follow all instructions provided with the device. Also ensure that you don't exceed the recommended usage time.

You need to push the activation button 2 times within 30 seconds after pulling the lever handle. If you don't do this properly, the device won't function effectively.

After pressing the activation button, hold the lever handle until the indicator flashes red. If the indicator doesn't go off, the lever may not be fully depressed. Make sure that it's fully depressed before turning it over. Once the lever handle is turned over, pull it until the indicator goes off. A loud sound indicates that the device is activated. You may now release the lever handle.

You need to repeat this procedure whenever you want to activate the device. After activating the device, leave it alone for 15 minutes. If you try to reactivate it sooner than 15 minutes, the device probably won't operate correctly.

In case the fire gets out of control, press the activation button again to deactivate the device. Do not attempt to put the fire out yourself, since the device was only meant to control the spread of a flame. Instead, call 9-1-1 immediately.

To deactivate the device, press the activation button until the indicator turns blue. Hold down the lever handle while holding down the activation button. Keep holding both buttons until the indicator turns off. Finally, turn the lever handle back over to its original position.

What Is Clean Agent HFC227 Ea Fire Extinguisher?

The product contains a high percentage of HFC227E (hydrofluorocarbon) and a small amount of Halon 1301 (bromochlorofluoroiodine). These two gases work together to create a powerful blanket around the area being protected from fire. Once the flames are extinguished, these gases are slowly released which helps to prevent rekindling of the fire.

Here are some general questions that will help you in understanding fire extinguishers in an easier way.

1. What type of extinguisher do I need?

Most buildings require two types of extinguishers; those that protect people and those that protect property. You should have at least one ABC (Class A) fire extinguisher stored near your entrance and exit points. These extinguishers work well and are safe to use. They should be filled with a chemical extinguishing agent such as Halon 1301 or CO2. If your building uses sprinkler systems, you may want to purchase additional extinguishers that are designed for water damage.

2. How often should I change my fire extinguishers?

It is recommended that you change your extinguishers every year. Firefighters recommend changing them out after two years. This ensures that they are working properly and that the chemicals inside the extinguishers are still effective. Changing them out before their expiration date is not only good for safety reasons, but also saves money!

3. How many extinguishers should I keep on hand?

You should keep 30 minutes worth of ABC extinguishers readily accessible at all times. Because they are designed to put out fires, you only need one. However, if you have a sprinkler system, you may need to purchase additional extinguishers to ensure your safety.

4. Where can I get fire extinguishers?

Fire extinguishers can be purchased online, at home improvement stores, hardware stores and even some sporting goods stores. Be sure to check the expiration dates on the labels.

5. Do fire extinguishers expire?

Yes, although you don’t know how old your current ones are, firefighters know exactly how long they will last. Check your fire extinguishers regularly to make sure they are still effective and replace any that are expired.
