It is not intended for use on an out-of-control fire, such as one which has reached the <a href="/wiki/Ceiling" title="Ceiling">ceiling</a>, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the equipment, personnel, resources or expertise of a <a href="/wiki/Fire_brigade" class="mw-redirect" title="Fire brigade">fire brigade</a>. Typically, a fire extinguisher consists of a hand-held cylindrical <a href="/wiki/Pressure_vessel" title="Pressure vessel">pressure vessel</a> containing an <a href="#Types_of_extinguishing_agents">agent</a> that can be discharged to extinguish a <a href="/wiki/Fire" title="Fire">fire</a>. Fire extinguishers manufactured with non-cylindrical pressure vessels also exist but are less common. </p><p>There are two main types of fire extinguishers: stored-pressure and cartridge-operated. In stored pressure units, the expellant is stored in the same chamber as the <a href="/wiki/Firefighting" title="Firefighting">firefighting</a> agent itself. Depending on the agent used, different propellants are used. With dry chemical extinguishers, <a href="/wiki/Nitrogen" title="Nitrogen">nitrogen</a> is typically used; water and foam extinguishers typically use <a href="/wiki/Air" class="mw-redirect" title="Air">air</a>. Stored pressure fire extinguishers are the most common type. Cartridge-operated extinguishers contain the expellant gas in a separate cartridge that is punctured before discharge, exposing the propellant to the extinguishing agent. This type is not as common, used primarily in areas such as industrial facilities, where they receive higher-than-average use. They have the advantage of simple and prompt recharge, allowing an operator to discharge the extinguisher, recharge it, and return to the fire in a reasonable amount of time. Unlike stored pressure types, these extinguishers use compressed <a href="/wiki/Carbon_dioxide" title="Carbon dioxide">carbon dioxide</a> instead of nitrogen, although nitrogen cartridges are used on low-temperature (–60 rated) models. Cartridge-operated extinguishers are available in dry chemical and dry powder types in the U.S. and water, wetting agent, foam, dry chemical (classes ABC and B.C.), and dry powder (class D) types in the rest of the world. </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Wheeled_fire_extinguisher.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/3/3c/Wheeled_fire_extinguisher.jpg/150px-Wheeled_fire_extinguisher.jpg" decoding="async" width="150" height="200" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/3/3c/Wheeled_fire_extinguisher.jpg/225px-Wheeled_fire_extinguisher.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/3/3c/Wheeled_fire_extinguisher.jpg/300px-Wheeled_fire_extinguisher.jpg 2x" data-file-width="2448" data-file-height="3264" /></a><figcaption>Wheeled fire extinguisher and a sign inside a parking lot</figcaption></figure> <p>Fire extinguishers are further divided into handheld and cart-mounted (also called wheeled extinguishers).

It consisted of a cask of fire-extinguishing liquid containing a <a href="/wiki/Pewter" title="Pewter">pewter</a> chamber of gunpowder. This was connected with a system of fuses which were ignited, exploding the gunpowder and scattering the solution. This device was probably used to a limited extent, as Bradley's Weekly Messenger for November 7, 1729, refers to its efficiency in stopping a fire in London. </p><p>A portable pressurised fire extinguisher, the 'Extincteur' was invented by British Captain <a href="/wiki/George_William_Manby" title="George William Manby">George William Manby</a> and demonstrated in 1816 to the 'Commissioners for the affairs of Barracks'; it consisted of a copper vessel of 3 <a href="/wiki/Gallon" title="Gallon">gallons</a> (13.6 liters) of pearl ash (<a href="/wiki/Potassium_carbonate" title="Potassium carbonate">potassium carbonate</a>) solution contained within <a href="/wiki/Pneumatics" title="Pneumatics">compressed air</a>.

Patent Office in Washington, DC under patent number 125,603. </p><p>The soda-acid extinguisher was first patented in 1866 by Francois Carlier of France, which mixed a solution of water and <a href="/wiki/Sodium_bicarbonate" title="Sodium bicarbonate">sodium bicarbonate</a> with <a href="/wiki/Tartaric_acid" title="Tartaric acid">tartaric acid</a>, producing the propellant <a href="/wiki/Carbon_dioxide" title="Carbon dioxide">carbon dioxide</a> (CO<sub style="font-size: 80%;vertical-align: -0.35em">2</sub>) gas. A soda-acid extinguisher was patented in the U.S. in 1880 by <a href="/w/index.php?title=Almon_M._Granger&action=edit&redlink=1" class="new" title="Almon M. Granger (page does not exist)">Almon M.

His extinguisher used the reaction between sodium bicarbonate solution and <a href="/wiki/Sulfuric_acid" title="Sulfuric acid">sulfuric acid</a> to expel pressurized water onto a fire.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> A vial of concentrated sulfuric acid was suspended in the cylinder. Depending on the type of extinguisher, the vial of acid could be broken in one of two ways. One used a plunger to break the acid vial, while the second released a <a href="/wiki/Lead" title="Lead">lead</a> stopple that held the vial closed. Once the acid was mixed with the bicarbonate solution, carbon dioxide gas was expelled and thereby pressurized the water. The pressurized water was forced from the canister through a nozzle or short length of hose.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p><p>The cartridge-operated extinguisher was invented by <a href="/wiki/Chubb_Fire#Read_and_Campbell_Limited" class="mw-redirect" title="Chubb Fire">Read & Campbell</a> of England in 1881, which used water or water-based solutions. They later invented a <a href="/wiki/Carbon_tetrachloride" title="Carbon tetrachloride">carbon tetrachloride</a> model called the "Petrolex" which was marketed toward automotive use.<sup id="cite_ref-urlStaffordshire_Past_Track_-Petrolex_half_gallon_fire_extinguisher_6-0" class="reference"><a href="#cite_note-urlStaffordshire_Past_Track_-Petrolex_half_gallon_fire_extinguisher-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p><p>The chemical foam extinguisher was invented in 1904 by <a href="/wiki/Aleksandr_Loran" title="Aleksandr Loran">Aleksandr Loran</a> in Russia, based on his previous invention of <a href="/wiki/Fire_fighting_foam" class="mw-redirect" title="Fire fighting foam">fire fighting foam</a>. Loran first used it to extinguish a pan of burning naphtha.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> It worked and looked similar to the soda-acid type, but the inner parts were slightly different. The main tank contained a solution of sodium bicarbonate in water, whilst the inner container (somewhat larger than the equivalent in a soda-acid unit) contained a solution of <a href="/wiki/Aluminium_sulphate" class="mw-redirect" title="Aluminium sulphate">aluminium sulphate</a>. When the solutions were mixed, usually by inverting the unit, the two liquids reacted to create a frothy foam, and carbon dioxide gas. The gas expelled the foam in the form of a jet. Although liquorice-root extracts and similar compounds were used as additives (stabilizing the foam by reinforcing the bubble-walls), there was no "foam compound" in these units. The foam was a combination of the products of the chemical reactions: <a href="/wiki/Sodium" title="Sodium">sodium</a> and <a href="/wiki/Aluminium" title="Aluminium">aluminium</a> salt-gels inflated by the carbon dioxide. Because of this, the foam was discharged directly from the unit, with no need for an aspirating branchpipe (as in newer mechanical foam types). Special versions were made for rough service, and vehicle mounting, known as apparatus of fire department types. Key features were a screw-down stopper that kept the liquids from mixing until it was manually opened, carrying straps, a longer hose, and a shut-off nozzle. Fire department types were often private label versions of major brands, sold by apparatus manufacturers to match their vehicles. Examples are Pirsch, Ward LaFrance, Mack, Seagrave, etc. These types are some of the most collectable extinguishers as they cross into both the apparatus restoration and fire extinguisher areas of interest. </p><p>In 1910, The <a href="/wiki/The_Pyrene_Company_Limited" title="The Pyrene Company Limited">Pyrene Manufacturing Company</a> of Delaware filed a patent for using carbon tetrachloride (CTC, or CCl<sub>4</sub>) to extinguish fires.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> The liquid vaporized and extinguished the flames by inhibiting the chemical chain reaction of the combustion process (it was an early 20th-century presupposition that the fire suppression ability of carbon tetrachloride relied on oxygen removal). In 1911, they patented a small, portable extinguisher that used the chemical.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> This consisted of a <a href="/wiki/Brass" title="Brass">brass</a> or <a href="/wiki/Chrome_plating" title="Chrome plating">chrome</a> container with an integrated handpump, which was used to expel a jet of liquid towards the fire. It was usually of 1 imperial quart (1.1 L) or 1 imperial pint (0.57 L) capacity but was also available in up to 2 imperial gallons (9.1 L) size. As the container was unpressurized, it could be refilled after use through a filling plug with a fresh supply of CTC.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Fire_grenade_P1950083.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/c/c7/Fire_grenade_P1950083.jpg/220px-Fire_grenade_P1950083.jpg" decoding="async" width="220" height="293" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/c7/Fire_grenade_P1950083.jpg/330px-Fire_grenade_P1950083.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/c7/Fire_grenade_P1950083.jpg/440px-Fire_grenade_P1950083.jpg 2x" data-file-width="3672" data-file-height="4896" /></a><figcaption>A fire grenade</figcaption></figure> <p><span class="anchor" id="Fire_grenade"></span>Another type of carbon tetrachloride extinguisher was the <b>fire grenade</b>. This consisted of a glass sphere filled with CTC, that was intended to be hurled at the base of a fire (early ones used salt-water, but CTC was more effective). Carbon tetrachloride was suitable for liquid and electrical fires and the extinguishers were fitted to motor vehicles. Carbon tetrachloride extinguishers were withdrawn in the 1950s because of the chemical's toxicity – exposure to high concentrations damages the nervous system and internal organs. Additionally, when used on a fire, the heat can convert CTC to <a href="/wiki/Phosgene" title="Phosgene">phosgene</a> gas,<sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> formerly used as a chemical weapon. </p><p>The carbon dioxide extinguisher was invented (at least in the US) by the <a href="/wiki/Walter_Kidde_Company" class="mw-redirect" title="Walter Kidde Company">Walter Kidde Company</a> in 1924 in response to Bell Telephone's request for an electrically non-conductive chemical for extinguishing the previously difficult-to-extinguish fires in telephone switchboards.

It was once thought that it worked by cooling, although this effect on most fires is negligible. An anecdotal report of a carbon dioxide fire extinguisher was published in <i><a href="/wiki/Scientific_American" title="Scientific American">Scientific American</a></i> in 1887 which describes the case of a basement fire at a <a href="/wiki/Louisville,_Kentucky" title="Louisville, Kentucky">Louisville, Kentucky</a> pharmacy which melted a lead pipe charge with CO<sub style="font-size: 80%;vertical-align: -0.35em">2</sub> (called carbonic acid gas at the time) intended for a <a href="/wiki/Soda_fountain" title="Soda fountain">soda fountain</a> which immediately extinguished the flames thus saving the building.<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup> Also in 1887, carbonic acid gas was described as a fire extinguisher for engine chemical fires at sea and ashore.<sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup> </p><p>In 1928, DuGas (later bought by <a href="/wiki/Ansul" title="Ansul">ANSUL</a>) came out with a cartridge-operated dry chemical extinguisher, which used sodium bicarbonate specially treated with chemicals to render it free-flowing and moisture-resistant.<sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-17" class="reference"><a href="#cite_note-17"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup> It consisted of a copper cylinder with an internal CO<sub style="font-size: 80%;vertical-align: -0.35em">2</sub> cartridge. The operator turned a wheel valve on top to puncture the cartridge and squeezed a lever on the valve at the end of the hose to discharge the chemical. This was the first agent available for large-scale three-dimensional liquid and pressurized gas fires, but remained largely a specialty type until the 1950s, when small dry chemical units were marketed for home use. ABC dry chemical came over from Europe in the 1950s, with Super-K being invented in the early 1960s and Purple-K being developed by the <a href="/wiki/United_States_Navy" title="United States Navy">United States Navy</a> in the late 1960s. Manually applied dry agents such as graphite for class D (metal) fires had existed since World War II, but it was not until 1949 that Ansul introduced a pressurized extinguisher using an external CO<sub style="font-size: 80%;vertical-align: -0.35em">2</sub> cartridge to discharge the agent. Met-L-X (<a href="/wiki/Sodium_chloride" title="Sodium chloride">sodium chloride</a>) was the first extinguisher developed in the US, with <a href="/wiki/Graphite" title="Graphite">graphite</a>, <a href="/wiki/Copper" title="Copper">copper</a>, and several other types being developed later. </p><p>In the 1940s, Germany invented the liquid <a href="/wiki/Bromochloromethane" title="Bromochloromethane">chlorobromomethane</a> (CBM) for use in aircraft. It was more effective and slightly less toxic than carbon tetrachloride and was used until 1969. <a href="/wiki/Methyl_bromide" class="mw-redirect" title="Methyl bromide">Methyl bromide</a> was discovered as an extinguishing agent in the 1920s and was used extensively in Europe. It is a low-pressure gas that works by inhibiting the chain reaction of the fire and is the most toxic of the vaporizing liquids, used until the 1960s. The vapor and combustion by-products of all vaporizing liquids were highly toxic and could cause death in confined spaces. </p><p>In the 1970s, Halon 1211 came over to the United States from Europe where it had been used since the late 1940s or early 1950s. Halon 1301 had been developed by DuPont and the <a href="/wiki/United_States_Army" title="United States Army">United States Army</a> in 1954. Both 1211 and 1301 work by inhibiting the chain reaction of the fire, and in the case of Halon 1211, cooling class A fuels as well. Halon is still in use today but is falling out of favor for many uses due to its environmental impact. Europe and Australia have severely restricted its use, since the Montreal Protocol of 1987. Less severe restrictions have been implemented in the United States, the Middle East, and Asia.<sup id="cite_ref-18" class="reference"><a href="#cite_note-18"><span

However, compliance with the Americans with Disabilities Act (ADA) also needs to be followed within the United States. The ADA height limit of the fire extinguisher, as measured at the handle, is 48 in (1.2 m). Fire extinguisher installations are also limited to protruding no more than 4 inches into the adjacent path of travel. The ADA rule states that any object adjacent to a path of travel may not project more than 4 in (10 cm) if the object's bottom leading edge is higher than 27 in (0.69 m). The 4-inch protrusion rule was designed to protect people with low-vision and those who are blind. The height limit rule of 48 inches is primarily related to access by people with wheelchairs but it is also related to other disabilities as well.

In the past, as solid charge model was produced, the AFFF concentrate was housed as a dry compound in an external, disposable cartridge in a specially designed nozzle. The extinguisher body was charged with plain water, and the discharge pressure mixed the foam concentrate with the water upon squeezing the lever. These extinguishers received double the rating of a pre-mix model (40-B instead of 20-B), but are now considered obsolete, as parts and refill cartridges have been discontinued by the manufacturer. European regulations require the phasing out of AFFF foams containing persistent organic pollutants.  These include PFAS (Per and PolyFluoroAlkylated Substances), PFOA (PerFluoroOctanoic Acid), its salts or PFOA related compounds, and PFOS (PerFluoroOctane Sulphonic acid), its salts or PFOS related compounds.  Related derogations allowing delay of their removal are to end on 4th July 2025.

Once existing stocks of charges and parts are depleted, the UL listings on these units will be void and they will require replacement with other extinguisher types.</li> <li>Film-forming fluoroprotein (<a href="/wiki/FFFP" class="mw-redirect" title="FFFP">FFFP</a>) contains naturally occurring proteins from animal by-products and synthetic film-forming agents to create a foam blanket that is more heat resistant than the strictly synthetic AFFF foams. FFFP works well on alcohol-based liquids and is used widely in motorsports. As of 2016, Amerex has discontinued production of FFFP, instead using AR-AFFF made by Solberg. Existing model 252 FFFP units could maintain their UL listing by using the new charge, prior to the Amerex completely exiting the foam market in December 2021. These units will be obsolete as soon as existing recharge agent stocks are depleted.</li> <li><a href="/wiki/Compressed_air_foam_system" title="Compressed air foam system">Compressed air foam system</a> (CAFS): The CAFS extinguisher (example: TRI-MAX Mini-CAF) differs from a standard stored-pressure premix foam extinguisher in that it operates at a higher pressure of 140 psi, aerates the foam with an attached compressed gas cylinder instead of an air-aspirating nozzle, and uses a drier foam solution with a higher concentrate-to-water ratio. Generally used to extend a water supply in wildland operations. Used on class A fires and with very dry foam on class B for vapor suppression.

Pump type water extinguishers are often used where freezing conditions may occur, as they can be economically freeze-protected with calcium chloride (except stainless steel models), such as barns, outbuildings and unheated warehouses. They are also useful where many, frequent spot fires may occur, such as during fire watch for hot work operations. They are dependent on the user's strength to produce a decent discharge stream for firefighting. Water and antifreeze are the most common, but loaded stream and foam designs were made in the past.

These extinguishers come in 1-3/4 and 2-1/2 gallon sizes, painted white in the United States. Models used in MRI facilities are non-magnetic and are safe for use inside the room that the MRI machine is operating.

It was developed in the late 1950s by the U.S. Navy for use on magnesium fires, especially crashed aircraft and aircraft wheel fires from hard landings. It is unique as an extinguishing agent in that the agent itself is a flammable liquid. When TMB contacts the fire, the methanol ignites and burns with a greenish flame due to the boron. As the methanol burns off, a glassy coating of boric oxide is left on the surface of the metal, creating an air-excluding crust. These extinguishers were made by the Ansul Chemical Co. utilizing TMB agent manufactured by the Callery Chemical Company, and were modified 2.5-gallon water extinguishers (Ansul used re-branded Elkhart extinguishers at the time), with a variable-stream nozzle that could deliver a straight stream or spray at the squeeze of a lever. A 6-inch fluorescent orange band with the letters "TMB" stenciled in black identified TMB from other extinguishers. This agent was problematic in that it had a shelf life of only six months to a year once the extinguisher was filled, since the methanol is extremely hygroscopic (absorbs moisture from the air), which causes corrosion to the extinguisher and renders its use on fire dangerous. These extinguishers were used from the 1950s–1970s in various applications, such as the MB-1 and MB-5 crash trucks.<sup id="cite_ref-40" class="reference"><a href="#cite_note-40"><span class="cite-bracket">[</span>39<span class="cite-bracket">]</span></a></sup> TMB was used experimentally by the US Air Force, specifically with regard to B-52 engine assemblies, and was tested in modified 10-gallon wheeled chlorobromomethane (CBM) extinguishers.

Halon 1211 was the most successful, and the combined TMB pressurized with halon 1211 and nitrogen was called Boralon and was used experimentally by the Los Alamos National Laboratory for use on atomic metals, using sealed cylinder extinguishers made by Metalcraft and Graviner which eliminated the moisture contamination problem.

To the difference of gaseous suppressants, which emit only gas, and dry chemical extinguishers, which release powder-like particles of a large size (25–150 <a href="/wiki/%CE%9Cm" class="mw-redirect" title="Μm">μm</a>) condensed aerosols are defined by the National Fire Protection Association as releasing finely divided solid particles (generally <10 μm), usually in addition to gas.<sup id="cite_ref-47" class="reference"><a href="#cite_note-47"><span class="cite-bracket">[</span>46<span class="cite-bracket">]</span></a></sup> </p><p>Whereas dry chemical systems must be directly aimed at the flame, condensed aerosols are flooding agents and therefore effective regardless of the location and height of the fire. Wet chemical systems, such as the kind generally found in foam extinguishers, must, similarly to dry chemical systems, be sprayed directionally, onto the fire. Additionally, wet chemicals (such as potassium carbonate) are dissolved in water, whereas the agents used in condensed aerosols are microscopic solids. </p> <div class="mw-heading mw-heading3"><h3 id="Experimental_techniques">Experimental techniques</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Fire_extinguisher&action=edit&section=16" title="Edit section: Experimental techniques"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In 2015, researchers from <a href="/wiki/George_Mason_University" title="George Mason University">George Mason University</a> announced that high volume sound with low <a href="/wiki/Bass_(sound)" title="Bass (sound)">bass</a> frequencies in the 30 to 60 <a href="/wiki/Hertz" title="Hertz">hertz</a> range drives oxygen away from the combustion surface, extinguishing the fire, a principle was previously tested by the <a href="/wiki/Defense_Advanced_Research_Projects_Agency" class="mw-redirect" title="Defense Advanced Research Projects Agency">Defense Advanced Research Projects Agency</a> (DARPA).<sup id="cite_ref-48" class="reference"><a href="#cite_note-48"><span class="cite-bracket">[</span>47<span class="cite-bracket">]</span></a></sup> One proposed application is to extinguish fires in <a href="/wiki/Outer_space" title="Outer space">outer space</a>, with none of the clean-up required for mass-based systems.<sup id="cite_ref-49" class="reference"><a href="#cite_note-49"><span class="cite-bracket">[</span>48<span class="cite-bracket">]</span></a></sup> </p><p>Another proposed solution for fire extinguishers in space is a vacuum cleaner that extracts the combustible materials.<sup id="cite_ref-50" class="reference"><a href="#cite_note-50"><span class="cite-bracket">[</span>49<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Maintenance">Maintenance</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Fire_extinguisher&action=edit&section=17" title="Edit section: Maintenance"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Fire7041.JPG" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/4/4d/Fire7041.JPG/220px-Fire7041.JPG" decoding="async" width="220" height="293" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/4/4d/Fire7041.JPG/330px-Fire7041.JPG 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/4/4d/Fire7041.JPG/440px-Fire7041.JPG 2x" data-file-width="2304" data-file-height="3072" /></a><figcaption>An empty fire extinguisher which was not replaced for years</figcaption></figure> <p>Most countries in the world require regular fire extinguisher maintenance by a competent person to operate safely and effectively, as part of fire safety legislation. Lack of maintenance can lead to an extinguisher not discharging when required, or rupturing when pressurized. Deaths have occurred, even in recent times, from corroded extinguishers exploding. </p><p>In the United States, state and local fire codes, as well as those established by federal agencies such as the <a href="/wiki/Occupational_Safety_and_Health_Administration" title="Occupational Safety and Health Administration">Occupational Safety and Health Administration</a>, are generally consistent with standards established by the <a href="/wiki/National_Fire_Protection_Association" title="National Fire Protection Association">National Fire Protection Association</a> (NFPA).<sup id="cite_ref-51" class="reference"><a href="#cite_note-51"><span class="cite-bracket">[</span>50<span class="cite-bracket">]</span></a></sup> They commonly require, for fire extinguishers in all buildings other than single-family dwellings, inspections every 30 days to ensure the unit is pressurized and unobstructed (done by an employee of the facility) and an annual inspection and service by a qualified technician. Some jurisdictions require more frequent service. The servicer places a tag on the extinguisher to indicate the type of service performed (annual inspection, recharge, new fire extinguisher). <a href="/wiki/Hydrostatic_pressure" class="mw-redirect" title="Hydrostatic pressure">Hydrostatic pressure</a> testing for all types of extinguishers is also required, generally every five years for water and CO<sub>2</sub> models up to every 12 years for dry chemical models. </p><p>Recently the NFPA and ICC voted to allow for the elimination of the 30-day inspection requirement so long as the fire extinguisher is monitored electronically. According to NFPA, the system must provide record keeping in the form of an electronic event log at the control panel. The system must also constantly monitor an extinguisher's physical presence, internal pressure and whether an obstruction exists that could prevent ready access. In the event that any of the above conditions are found, the system must send an alert to officials so they can immediately rectify the situation. Electronic monitoring can be wired or wireless. </p><p>In the UK, three types of maintenance are required: </p> <ul><li>Basic service: All types of extinguisher require a basic inspection annually to check weight, externally validate the correct pressure, and find any signs of damage or corrosion. Cartridge extinguishers are to be opened up for internal inspection, and to have the weight of the cartridge tested. Labels must be inspected for legibility, and where possible, dip tubes, hoses and mechanisms must be tested for clear, free operation.</li> <li>Extended service: Water, wet chemical, foam, and powder extinguishers require a more detailed examination every five years, including a test discharge and recharge. On stored pressure extinguishers, this is the only opportunity to internally inspect for damage/corrosion.</li> <li>Overhaul: CO<sub>2</sub> extinguishers, due to their high operating pressure, are subject to pressure vessel safety legislation, and must be hydraulic pressure tested, inspected internally and externally, and date stamped every 10 years. As it cannot be pressure tested, a new valve is also fitted. If any part of the extinguisher is replaced with a part from another manufacturer, then the extinguisher will lose its fire rating.</li></ul> <p>In the United States, there are three types of service: </p> <ul><li>Maintenance inspection <sup id="cite_ref-52" class="reference"><a href="#cite_note-52"><span class="cite-bracket">[</span>51<span class="cite-bracket">]</span></a></sup></li> <li>Internal maintenance: <ul><li>Water – annually (some states) or 5 years (NFPA 10, 2010 edition)</li> <li>Foam – every 3 years</li> <li>Wet chemical, and CO<sub style="font-size: 80%;vertical-align: -0.35em">2</sub> – every 5 years</li> <li>Dry chemical and dry powder – every 6 years</li> <li>Halon and clean agents – every 6 years.</li> <li>Cartridge-operated dry chemical or dry powder – annually</li> <li>Stored-pressure dry chemical mounted on vehicles – annually</li></ul></li> <li>Hydrostatic testing</li></ul> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Fire_Extinguisher.JPG" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/c/cf/Fire_Extinguisher.JPG/170px-Fire_Extinguisher.JPG" decoding="async" width="170" height="227" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/cf/Fire_Extinguisher.JPG/255px-Fire_Extinguisher.JPG 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/cf/Fire_Extinguisher.JPG/340px-Fire_Extinguisher.JPG 2x" data-file-width="1944" data-file-height="2592" /></a><figcaption>A fire extinguisher stored inside a cabinet mounted to a wall</figcaption></figure> <p>In open public spaces, extinguishers are ideally kept inside cabinets that have glass that must be broken to access the extinguisher, or which emit an alarm siren that cannot be shut off without a key, to alert people the extinguisher has been handled by an unauthorized person if a fire is not present.
