When it comes to fire safety, making sure your home or workplace is prepared with the right type of fire extinguisher is a big deal. Of course, if the fire is significant, your priority should be to evacuate your home or office immediately and wait for firefighters outside.

Keeping yourself and others safe in both your home and your workplace is important.

The types of fire extinguishers used on board ships depend on the types of fire on a ship and the material which is acting as fuel. As fires are classified on the basis of the kind of fuel which sources them, fire extinguishers are also classified on the same grounds. The firefighting system and fire extinguisher types on board ships can be classified into three category —.

Different Types of Fire Extinguishers Used on Ships

The types of fire extinguishers used on board ships depend on the types of fire on a ship and the material which is acting as fuel. As fires are classified on the basis of the kind of fuel which sources them, fire extinguishers are also classified on the same grounds.

The firefighting system and fire extinguisher types on board ships can be classified into three category —. This makes it easy for the crew to act immediately by choosing the correct type of fire extinguisher on a particular class of fire on board ship. A portable fire extinguisher is one of the most convenient and speedy ways to fight the fire on ships. Class A: These types of fire extinguishers are used in fires which are a result of the burning of wood, glass fibre, upholstery, and furnishing.

Foam agents also help in separating the oxygen part from the other aspects. For extinguishing this class of fire, Dry Powder extinguishers are used which is similar to dry chemical besides they extinguish the fire by isolating the oxygen from the fuel or by eliminating the heat factor of the fire triangle. The dry powder extinguishers are only used for class D fires and they cannot be used for other classification of fire on board ship.

Hence, if a portable extinguisher with a conductive agent is used for fighting the class E fire, it may lead to a risk of shock to the operator. CO2 or DCP portable fire extinguisher is used in such fires. When it comes to choosing a ship fire extinguisher, we need to keep in mind different types of combustible material and fluids which are located in different parts of the ship along with the fire extinguisher reaction with the source of a fire.

Based on the above-mentioned classification, portable fire extinguishers are classified and used according to the classes of fire as per IMO. The portable type onboard fire extinguisher used in the marine or maritime setup is also known as plunger type fire extinguishers because of the plunger mechanism used to release the extinguishing agent.

There are five main types of fire extinguishers used on ships:. The soda acid extinguisher can be found in the accommodation area of the ship.

Sodium bicarbonate soda and sulphuric acid are the prime components of the extinguisher. They combine to form a chemical reaction to produce carbon dioxide gas, which is used to smother the fire. The arrangement of the extinguishers comprises of a container which holds the sodium bicarbonate solution. A small glass bottle phial containing sulphuric acid is placed below a plunger mechanism, which is covered by a safety glass along with a screw and cap at the top. When the plunger is struck hard, the glass bottle breaks, resulting in mixing of acid and soda, a chemical reaction takes place which produces carbon dioxide gas.

The carbon dioxide gas pressurises the space above the liquid used for extinguishing the fire and forces it out through the internal pipe of the nozzle. Note: As the CO2, which is used in soda acid fire extinguisher, may create a toxic effect in confined spaces, Soda Acid Extinguishers are now banned on ships.

To counter the A-Class fire, portable water type fire extinguisher of 9Ltr are used. The outer container is filled with water and fitted with a CO2 Cartridge inner container which forces the water out of the container with pressure. When pressure is applied on the plunger, the CO2 cartridge ruptures and forces the water out of the extinguisher. Foam extinguishers are used to extinguish Class B fires and are located near flammable liquids.

There can be two types of foam fire extinguisher depending upon its contents-. The main container is filled with sodium bicarbonate, whereas the inner container is filled with aluminium sulphate. Chemical foam extinguisher diagram:. The plunger is turned to release the cap and the extinguisher is then inverted for both the chemicals to mix.

Carbon dioxide is produced from the chemical reaction which pressurizes the container from inside and forces out the foam. Note: Chemical Foam Extinguishers are now banned on ships because of the poisonous effect which the gas can create. The mechanical foam fire extinguisher uses a long hosepipe connected to the dip tube inside the internal structure of fire extinguisher which allows it to use the foam portable fire extinguisher upright.

The central container has a plunger mechanism at the top which when depressed releases the carbon dioxide and allows foam and water to mix. The foam and water come out of the nozzle, creating mechanical foam. This extinguisher is operated in an upright position. Carbon dioxide extinguishers are mainly used for class B or class C fires.

They are not used for accommodation areas and confined spaces because of the gas used in lethal. These are widely used as engine room fire extinguisher. Carbon dioxide is stored in liquid form under pressure. A central tube acts as an outlet for carbon dioxide gas. A plunger attached to a bursting disc at one end and a trigger at the other is used to release the carbon dioxide gas.

The liquid changes to gas as it comes out of the extinguisher through a hose. Sodium bicarbonate powder is used to extinguish almost all types of fires. It is mainly located in the engine room and near electrical equipment. When the plunger is pushed, it releases the carbon dioxide gas, which in turn forces the dry powder out of the discharge nozzle. The semi-portable type of fire extinguisher is higher in capacity and weight than the portable ones. They are considered to be the second line of defense in case the portable fire extinguisher fails to stop the fire exposure.

As they are heavier to lift, it is provided with a wheel-trolley arrangement which can be dragged to a nearby fire location. These can be a semi-portable foam fire extinguisher or semi-portable DCP type fire extinguisher. These extinguishers are kept onboard on that location which has a higher risk of fire.

The semi-portable type fire extinguisher is located near the boiler and incinerator in the engine room and also in the galley. The galley fire fighting system in a ship may include a small CO2 fixed firefighting setup apart from the portable galley fire extinguisher.

This type of portable fire fighting unit consist of a portable foam tank carrying foam-forming liquid of at least 20l capacity with foam applicator connected to an inductor type nozzle designed to be connected to the fire main by a hose.

One spare tank of foam making liquid is also provided. The nozzle shall be capable of producing the rate of at least 1. CTC fire extinguisher: The CTC extinguisher used to be very effective extinguisher for combating the small fire, However, due to its tendency to emit harmful toxic phosgene gas, it is no more used on ships.

Non aspirated foam, AFFF , with spray applicators, is the norm.

Please keep up! Bill: Thank you for your comment. Stored pressure type are still used and not banned by the authority. Soda acid an chemical foam are no more used and clearly stated in the article.

This article talks about the different types of fires on ships, such as fuel fires, and every structure has different types of materials that can catch on fire so using the correct fire extinguisher is paramount.

I also believe that homes should be equipped with several types of fire extinguishers because household fires are more common than most people would think. If you need any more information on the different classes of fires and the appropriate fire extinguishers to be used in each scenario. I appreciate that you explained carbon dioxide extinguishers have the CO2 stored in liquid form under pressure. Thank you for helping me learn more about how this works and that a CO2 refill is possible to keep it in working order.

The solution is the autonomous self igniting non pressurized fire extinguisher inside of the cargo containers that activate themselves in case of fire. We have this equipment to serve the safety of containers and container ships.

Understanding fire extinguisher classes

Диаграмма чем-то напоминала бычий глаз. В центре находился красный кружок с надписью БАЗА, вокруг которого располагались пять концентрических окружностей разной толщины и разного цвета. Внешняя окружность была затуманена и казалась почти прозрачной. - У нас имеется пять уровней защиты, - объяснял Джабба.  - Главный бастион, два набора пакетных фильтров для Протокола передачи файлов, Х-одиннадцать, туннельный блок и, наконец, окно авторизации справа от проекта Трюфель.

 - В голосе звонившего по-прежнему чувствовалась нерешительность.  - Ну, тогда… надеюсь, хлопот не. - Отлично.

 Это не смешно, Чед. Заместитель директора только что солгал директорской канцелярии. Я хочу знать. Бринкерхофф уже пожалел, что не дал ей спокойно уйти домой. Телефонный разговор со Стратмором взбесил .

То, что она увидела, привело ее в ужас. С интервалом в три минуты была зарегистрирована вторая серия команд запирания-отпирания. Согласно регистру, кто-то открывал ее компьютер, пока ее не было в комнате. Но это невозможно. У нее перехватило дыхание.

Я умер.

 Он убьет. Я чувствую. Ведь я слишком много знаю. - Успокойся, Грег. Сирена продолжала завывать.

И весь мир сразу же узнает о ТРАНСТЕКСТЕ. Сьюзан вопросительно смотрела на. - Это совсем просто, Сьюзан, мы позволим правде выйти за эти стены. Мы скажем миру, что у АНБ есть компьютер, способный взломать любой код, кроме Цифровой крепости, - И все бросятся доставать Цифровую крепость… не зная, что для нас это пройденный этап. Стратмор кивнул: - Совершенно .

Ему вдруг страшно захотелось увидеть ее - сейчас. Прохладный ветерок кондиционера напомнил ему о жаре на улице. Он представил себе, как бредет, обливаясь потом, по душным, пропитанным запахом наркотиков улицам Трианы, пытаясь разыскать девчонку-панка в майке с британским флагом на груди, и снова подумал о Сьюзан. - Zumo de arandano, - с удивлением услышал он собственный голос.

Единственный исполнитель. Сьюзан пронзила ужасная мысль. Этой своей мнимой перепиской Танкадо мог убедить Стратмора в чем угодно. Она вспомнила свою первую реакцию на рассказ Стратмора об алгоритме, не поддающемся взлому.

К несчастью, это был самый надежный способ собрать в шифровалке всех сотрудников Отдела обеспечения системной безопасности.
