How do soda-acid fire extinguishers work?
The body of the extinguisher contains sodium bicarbonate dissolved in water. In the top, there is a bottle of acid. When someone turns the extinguisher upside down, the sodium bicarbonate and acid reacts to release carbon dioxide under pressure. The water/acid solution is then forced out of the extinguisher under pressure.

That depends entirely on what type of extinguisher it is. Air pressurized water extinguishers contain compressed air and water, the former forcing out the latter up through an uptake tube and out the hose. For use at low temperatures, an antifreeze might be added to the water Foam extinguisher…s are similar to air pressurized water extinguishers, but the water is mixed with foaming agents and small holes are added near the top of the uptake tube to aerate the extinguishing agent. Dry chemical extinguishers contain a powdered agent (bicarbonate of soda, ammonium phosphate, potassium bicarbonate, potassium chloride, &c.) and a compressed gas, usually nitrogen. The latter propels the former out the nozzle or hose. Carbon dioxide extinguishers contain liquefied carbon dioxide under high pressure. Halon and other clean agent extinguishers contain a variety of chemicals of varying risk to the ozone layer. Dry powder extinguishers are typically buckets containing the extinguishing agent (sodium chloride mixed with thermoplastic, powdered copper, graphite, sodium carbonate, &c.) which are shoveled onto the burning metal. Sometimes these agents are placed in containers more typical of what we think of as a fire extinguisher. Kitchen or type-K extinguishers are similar to foam extinguishers, but contain a soap-like emulsifier that brings the burning lipids into solution with the water. Dry chemical and dry powder extinguishers are also available in cartridge-operated forms where a large amount of powder is contained in the main body of the extinguisher, and gas cartridges are attached to pressurize the unit. This allows the unit to be recharged more quickly an on site, not requiring special equipment. In this case, the pressurized gas is typically carbon dioxide, and is stored in a separate container, punctured at the start of use. ( Full Answer )
You would have to drop the fire extinguisher on its head because the carbonate and the acid are separated and one of them in a glass container at the top of the extinguisher dropping it on its head would break the glass and make the chemicals connect together and a chemical reaction would take place… then the extinguisher would be ready for use. In the glass container there also would be some sort of detergent that made the extinguishing formula froffy. ( Full Answer )
A fire extinguisher is a cylindrical metal container which is used to put out fires. It usually contains a foam or vaporizing liquid. The contents are pressurized in order to produce a powerful spray of water, foam or powder to put out a fire. Have you ever realized how important fire extinguis…her safety is for you and your family? When you are planning ahead and preparing for emergencies, you will want to purchase fire extinguishers for your home , and for each of your cars. The more you have the safer you are! Do you have home fire extinguishers on hand and ready in case of a fire? Fire extinguishers should be ready and available in several places throughout your home. The first place to have a fire extinguisher is near your stove. Make sure that your kitchen fire extinguisher is not too close to the stove, due to the fact that a fire may occur and you may not have access to the fire extinguisher because of the flames. The best location for your fire extinguisher will be between six and eight feet away from the stove. The garage would be another good location for a fire extinguisher. There are many types of fires that can start in a garage so you would want to have your fire extinguisher easily accessible. Knowing that you have fire extinguishers in several key places throughout your home will help you and your family to be better prepared for a fire emergency. How to use a home fire extinguisher: . Remove the fire extinguisher from its mount. . Hold the fire extinguisher while pulling out the pin. (do not squeeze the trigger while pulling the pin) . Aim the fire extinguisher at the base of the fire. . Squeeze the trigger and spray back and forth over the fire. Remember that there are different types of home fire extinguishers, some of them have a small hose to aim at the fire, while the smaller units have just a nozzle. Another thing to remember is you should learn how to use a fire extinguisher before a fire occurs. It is not a good idea to try and read the instructions while you are in an emergency situation.

Baking soda contains three products: sodium carbonate, water vapor(gas), and carbon dioxide . In order for there to be a fire, 3 elements must be present (oxygen being one of them). Since baking soda contains carbon dioxide which smothers the fire, not allowing the oxygen to get to the flame, theref…ore extinguishing the fire. ( Full Answer )
a bicarbonate of baking soda is Co2 Co2 displaces oxygen which is fuel for the fire no fuel no fire
The "Fire Triangle" indicates that a fire requires fuel, oxygen andheat to continue burning. Removing any one side will cause thereaction to cease. You can: . Remove the source fuel (turn off gas or oil supply to thefire) . Smother the fire with barriers such as foams, sand (or otherinert materia…l) . Cool it with water or carbon dioxide . Tie up the reactants with compounds that bind with the oxygenmore rapidly (Halon) . Replace the oxygen in the air with carbon dioxide or otherinert gas (Halon) I have one suggestion to all that if you have any damaged fireextinguisher then you can sell it on Halon.Us. Thank you all.

A soda-acid extinguisher expells water (actually a dilute sodium sulfate solution formed by the reaction of the soda and the acid). Therefore, it's used on the same types of fires as normal water extinguishers; wood, paper, textiles and so on. It must NOT be used on burning liquids (which would be s…plashed around, sperading the fire) or on live electrical equipment (becuse of the risk of electrocution). ( Full Answer )
Vinegar and bicarbonate of soda can extinguish some fires, because these two substances react to form carbon dioxide gas, which can not support combustion and is denser than air, so that it tends to settle over a burning material and thereby cut off the supply of atmospheric oxygen that the fire …requires to continue burning. .

a fire extinguisher work on the rule that a fire needs 3 things to burn 1. fuel (wood ,gas) 2. heat 3. oxygen with out any of these a fire will not burn a ABC dry chem extinguisher removes the oxygen while a hydrogen extinguisher removes the heat
Soda acid fire extinguishers contain c02 that is created when the extinguisher is inverted and the acidic water is mixed with the soda inside the lid. The pressure of the CO2 forces the acidic water out the hose and (hopefully) onto the fire. Soda-acid extinguishers are no longer allowed in any U…S occupancy requiring a fire extinguisher (i.e., anywhere other than a residential dwelling). ( Full Answer )
Generally speaking, we extinguish a fire by removing air (oxygen) so the fire cannot breathe, we remove fuel that is being burned, or we remove thermal energy from the fire so that combustion cannot be sustained. There are a number of different tactics and strategies that firefighters use to suppres…s a fire. Additionally, there are a number of different types of fire, and the effective firefighter will adjust an approach to be more effective for a given situation. We call upon our knowledge of the fire triangle to chart a course toward successful fire suppression. We know that a fire needs fuel to burn, heat to cause the fuel to burn, and oxygen in the air to sustain combustion. To attack a fire, a firefighter usually aims to "break" the fire triangle by removing on of the three "legs" that supports the fire triangle. By suffocation, cooling or the removal of the fuel, we can break the fire triangle and put out a fire. Most of us know about special situations where a modified system or approach is necessary for suppression to be effective. In the case of burning metals, water is often not used as it actually supports the chemical reactions in combustion. Water isn't a good idea for burning liquids, either. Likewise, it is wise to use something else other than water on electrical fires. But the basic strategy is essentially the same. Discover the things at work in a given fire and pick a way to remove or inhibit the actions of one or more things so the fire can be controlled and extinguished. ( Full Answer )
spreading foam on fire creates a blanket which does not allow oxygen to get inside and without oxygen fire doesn't burn
Fire needs three things; oxygen, fuel, and heat. When baking soda is put on a fire it displaces the oxygen around the fire. Once the oxygen is gone, the fire can't keep burning.
A fire extinguisher puts out a fire by: . cooling the burning material enough that it stops burning, or . excluding oxygen from the burning material so that it cannot continue, or . both
CO2 Fire Extinguisher Features . CO2 is a non-flammable gas, which is stored in the extinguisher under pressure as a liquid. CO2 fire extinguishers work best for Class B and C fires. Class B fires are caused by flammable or combustible liquids including gasoline or kerosene, or grease as in kitch…en fires. Class C fires are those occurring around electrical equipment such as computers, fax machines, wiring and circuit breakers. CO2 is harmless to electrical equipment. The current should be shut off before using the fire extinguisher. . ( Full Answer )

hey! You will need the following things : 1) a hollow glass tube or a eye dropper 2) a big glass bottle 3) a bottle of vinegar 4) a box of baking soda 6 ) a rubber or cork stopper that fit the big bottle 7) paper towel and a rubber band 8) water First thing to is remove the rubber squ…eeze bulb on the eye dropper and keep the glass tube and make a hole slightly smaller than the glass tube in the rubber or cork bottle stopper and insert the glass tube in the stopper until the tip of tube come out of the stopper . ( Do this slowly ; so not to break the glass) Put baking soda on the sheet of paper towel and attract the corners to the other end of the tube to the rubber stopper securing with the rubber band than fill the big bottle: 1/3 full of vinegar and the other 1/3 with water leaving the bottle about half full Than carefully insert the rubber stopper on the big bottle with the bag of soda hanging above the vinegar water solution. Make sure it a tight seal on the bottle when you ready to use Tip the bottle over and wait a minute or two than the water will shoot out of the tip and you have a working Fire extinguisher I hope this help ( Full Answer )
You turn it upside down or strike a plunger (depends on model), to release sulfuric acid into the water containing sodium bicarbonate, resulting in carbon dioxide gas pressure. The pressurized gas expels the water/acid solution out the hose. Of course, under most US and Canadian fire codes, this t…ype of fire extinguisher has been obsolete for many years and must be removed from service immediately, if any are found. ( Full Answer )
Weak sulfuric acid was contained in these obsolete extinguishers, and the acid would mix with the sodium bicarbonate extinguishing agent, producing Carbon Dioxide gas to pressurize the container, resulting in acid/bicarb mixture being expelled under pressure, through the hose.
remember the acronym PASS P-pull A-aim S-Squeeze S-Sweep which means you pull out the pin, aim at the fire, squeeze the handle, and spray in a sweeping motion
so that you don't die if your working with fire! i mean really use your head. you'd have to be a blond not to look for a fire extinguisher! (: no offense to all of the blonds out there.
We have typical ones with CO2, Water and Powder. All with their specific type of use. CO2 removes oxygen, depriving the material burning from needed oxygen. It also cools down the area on fire but this effect is not substantial on a large fire. It does not conduct electricity. Powder is an nonbur…nable compound with a large surface that absorbs heat. It cools down the fire and as temperature falls, the fire will not be able to continue. It does not conduct electricity. Water is able to absorb a lot of heat. heat will in turn transform water into steam that expands and removes oxygen. The transformation of water into steam takes its energy from the fire and lowers temperature. It has the disadvantage of conducting electricity, hence it should not be used where there are electricity. ( Full Answer )
Mixing vinegar and baking soda produces carbon dioxide. The carbon dioxide will extinguish the fire because the fire can only burn with oxygen.
They have 2 Different chambers 1 contains in a glass vale sulfuric acid 2 Containes in the canister sodium bicarbinate when you mix (by shacking or turning over or strike a plunger) they produce co2 wich expells the water out excuse the spelling mistakes lol
Yes pure baking soda is used as it behaves as a basic medium which reacts with CO2 gas n then d reacted product is sprayed on d fire which extinguishes d fire ....because of it neutral behavior....
the foam which is produced releases carbon dioxide which takes away oxygen example burning flame
either: . removing oxygen to suffocate the fire; . removing heat to stop further ignition; or . changing the chemical reaction with the fuel But I have one suggestion for for all, That if you have any damagedfire extinguisher then Halon.Us is a best place to sell it.RecentlyI had also sold my… damaged extinguisher there with an affordableprice. ( Full Answer )
it contains a metallic bin,which at inside contains sodium bi carbonate and concentrated sulfuric acid
It depends on the type. If it's not readily apparent, you should probably just get a new one.
Fires need 3 things to burn; oxygen, heat and fuel. By using carbon dioxide you are eliminating the oxygen corner of the triangle, so the fire goes out.
I can only think of three types, but I'm no fire science guy. There is the CO2 extinguisher, the chemical foam extinguisher, and the chemical powder extinguisher. They ALL work on exactly the same principals. Fire must have three things to exist: Fuel, Oxygen, and Heat. Knock out any one of those th…ings, and fire cannot burn. CO2, foam, and powder all displace oxygen and absorb heat. ( Full Answer )
Both nitric acid and hydrochloric acid are highly corrosive. If sprayed on a fire they will boil and cause serious chemical burns. Additionally, nitric acid as an oxidizer and could potentially make a fire even more intense.
A soda acid fire extinguisher will discharge water under thepressure created by the production of carbon dioxide gas. Thecreation of the carbon dioxide is due to the chemical reaction ofacid an soda mixing.
It doesn't. They are completely banned under modern fire codes. However, the operation is this: when you invert the can, the weak acid solution mixes with the bicarbonate soda inside the top lid, creating a carbon-dioxide gas under pressure, pushing the acid solution out the hose and (hopefully) …onto the burning materials. ( Full Answer )
It contains a solution of bicarbonate of soda and a bottle of sulfuric acid. When the bottle is inverted or uncorked, the acid mixes with the bicarb, creating carbon dioxide gas, pressurizing the container and forcing the liquid out through the nozzle, spraying an acid/bicarb mixture on the fire. … Needless to say, there are good reasons such a thing is obsolete and completely illegal to use in any structure the USA.

Hi, Fire extinguisher is very easy to use . Here I mention 3 stepson how to use. step - 1 : Pull the pin - This will allow you to discharge theextinguisher. step - 2 :Squeeze the top handle or lever - This depresses a buttonthat releases the pressurized extinguishing agent in theextinguisher. step- …3 : Sweep from side to side - until the fire is completelyout. Start using the extinguisher from a safe distance away, thenmove forward. Once the fire is out, keep an eye on the area in caseit re-ignites. But be careful that when you are using an extinguisher. I have onesuggestion that you can sell your damaged extinguisher to halon.us. ( Full Answer )

In the USA it is no longer permissible to have soda-acid extinguishers for fire protection. They are obsolete. NFPA 1: 13.6.6 (2009). In other places, however, you would invert the tank, causing the acid to mix with the soda, creating CO2 gas, which pressurizes and pushes the acid/soda/water mixt…ure out through the hose. Some units require you to whack a knob on the top to break the acid bottle before inverting the whole unit. ( Full Answer )
When the discharge valve is opened, the CO2 is forced out of the tank by pressure, and changes to CO2 gas. This is a heavy gas that will not burn, and blocks the fire from getting oxygen.
Acid can corrode the metal shell of the extinguisher. When it is rapidly pressurized, it may explode. They are no longer an approved extinguisher in many nations.
In 1881, Almon M Granger patented a fire extinguisher which used the reaction between sodium bicarbonate and sulfuric acid to expel pressurized water. When the acid and bicarbonate mixed, carbon dioxide gas was released - which pressurized the water. These were still reasonably common up until th…e 1920s, but are not one of the common types of fire extinguishers used today. ( Full Answer )
CO 2 is compressed in the cylinder and sealed with a valve. The valve is opened during operation and the compressed CO 2 escapes under pressure.
Most of the contents of soda-acid extinguishers (which are obsoleteand completely illegal in the USA) is water. Water and oil don'tmix well. The water may actually spread an oil fire as the flamingoil expands across the surface of the newly created puddle of wateror as the oil is splashed in all dir…ections by the force of thespray. Soda-acid extinguishers can also be hazardous to operate even tofight the type of fire they were designed to fight (wood or paperfires) due to the fact that they contain a jar of sulphuric acid.As the user must invert the extinguisher first to dump thesulphuric acid into the sodium bicarbonate solution in the body ofthe extinguisher there is a chance that if something is wrong withthe extinguisher or the user holds the nozzle wrong at that moment,he might get sulphuric acid on his skin or clothes!

Fires are generally extinguished by removing part of the processthat makes them keep going, sometimes called the "firetetrahedron": fuel, oxygen, heat, chemical reaction. For example, putting water on a big fire causes the water to turnto steam, which is a cooling process, removing the heat from th…efire. Water that gets onto the surface of the fuel also reduces theamount of oxygen available for burning and changes the fuel byraising its ignition temperature. It's harder to light wet fuelthan dry fuel. Some fire extinguishing methods involve "smothering" the fire, i.e.cutting off the supply of oxygen. Carbon dioxide and foamextinguishers are examples of extinguishers that work on thisprinciple. They also absorb much of the heat from the fire, whichprovides a secondary, lesser fire extinguishing benefit. Some fire require adding substances to the fire that interrupt thechemical reaction. Most of these are halogenated organics - broadlyreferred to as Halons. At high temperatures, halons decompose torelease halogen atoms that combine readily with active hydrogenatoms, quenching flame propagation reactions even when adequatefuel, oxygen, and heat remain. The preferred halogens are bromineand iodine although chlorine and fluorine can also help quenchfires. ( Full Answer )
A fire extinguisher service checks that the extinguisher hasn't been tampered with and ensures that it is still full and in good working order should you need it.
A CO2 fire extinguisher will work on flammable liquid and electrical fires only. If used on any other type of fire they will just give it more oxygen and it will spread.
When sprayed on a hot surface, the powder fuses into a stickycoating that cuts off the air to the fire.
Fire is initiated through the availability of three factors together: . oxygen (or air) . material that has the ability to be extenguished (wood, cloth, fuel, ...) . the means for setting fire (material friction in dry air, remains of a cigarette, ...) Extinguishinh fire is done mainly through… insulating the burned subsatance from oxygen using water or other extenguishing materials. ( Full Answer )
Carbon dioxide does not support combustion, and as it is quite dense, it forms an invisible layer around the fuel which keeps the oxygen out.
This type of extinguisher sprays mostly water and most flammableliquids float on water, so it would simply spread the burningliquid over a larger area causing the fire to grow.
