In about BC, the Roman Ctesibius of Alexandria is credited with inventing a hand operated fire pump able to deliver a stream of water to a fire. It was the precursor for other variants on his fire pump using oscillating pistons to force water out of a container under pressure. They were used well into the 20th Century. The squirt worked rather like a syringe. The nozzle end was dipped into water and a few pints of water then sucked up into the chamber by pulling out the plunger. The charged squirt was then directed at the fire and the plunger pushed home to eject the water.

In about BC, the Roman Ctesibius of Alexandria is credited with inventing a hand operated fire pump able to deliver a stream of water to a fire. It was the precursor for other variants on his fire pump using oscillating pistons to force water out of a container under pressure. They were used well into the 20th Century. The squirt worked rather like a syringe. The nozzle end was dipped into water and a few pints of water then sucked up into the chamber by pulling out the plunger.

The charged squirt was then directed at the fire and the plunger pushed home to eject the water. Squirts were used on the Great Fire of London although as can be deduced from a previous blog, with no measurable effect.

Today they survive as a fun if annoying kids toy. The first version of the modern portable fire extinguisher was invented by Captain George William Manby in , comprising of a copper vessel holding 3 gallons of pearl ash potassium carbonate solution under compressed air pressure.

Around Pyrene pioneered the carbon tetrachloride or CTC extinguisher, where the liquid was expelled from a container by hand pump, onto a fire. The CTC vapourised much like modern CO2 extinguishers, controlling the flames by a combination of air exclusion and chemical reaction. The problem was CTC vapour is highly toxic so using them could be more hazardous than the fire itself. The late 19th century also saw the invention of the soda-acid extinguisher, the thing worked by breaking a vial of sulphuric acid suspended in a cylinder containing a solution of water and sodium bicarbonate.

The Bicarbonate apparently neutralised the acid but the subsequent violent reaction expelled the solution under pressure through a tube and nozzle. Percy Julian, another prominent African-American is attributed with inventing the aero-foam extinguisher for use against gas and oil fires during World War II and by the middle of the twentieth century the modern type of extinguisher appeared using different extinguishing agents to combat different types of fire with either cartridge pressure or stored pressure expirant.

As a footnote historians have determined that in the 1st Century AD the Romans had approximately 7, paid fire fighters. The Roman equivalent of the Regulatory Reform Order I guess, but probably with a more corporal style of punishment. At that time the population of Rome is put at around a million people. A lot has changed in years but have you noticed the helmets are not that different!! Have a look at our range of fire extinguishers, including water fire extinguishers , dry powder fire extinguishers , foam fire extinguishers , CO2 fire extinguishers and more.

I am a museum curator with a brass Pyrene carbon tetrachloride fire extinguisher in my collection. It appears to be full. Is it safe for me to keep it? Should I discharge the contents, if so where and how or would it be better for me to arrange for it to be removed from the collections? Unfortunately this is a potentially harmful liquid and can be extremely hazardous to the environment and your health.

Bear in mind that the extinguisher will not spontaneously discharge so there is no need for immediate panic. Carbon tetrachloride is a volatile, clear, colourless, heavy liquid, and is also an ozone-depleting chemical. It has a distinctive sweet small that can be detected at low levels so if you have any leaks you would probably be alerted by now.

If you believe your CTC extinguisher to be full contact your local government Environmental Officer for advice on the safe disposal of Hazardous Waste. Do not attempt to dispose of the liquid yourself as this is an offence and can be extremely dangerous and there is also the potential for possible legal action being brought for environmental contamination.

You should also check your collection to see if you have a Halon fire extinguisher as these are also illegal to own and discharge although as a museum you should have exemption.

The canister is normally coloured Green which is perverse given its connection with ozone depletion. There are some gold coloured ones around. Halon is sometimes recycled for approved uses to minimise the need for manufacture. Both these extinguishers are perfectly safe to put back on display once the contents have been discharged. I hope this helps.

T fire extinguisher. Can you tell me if this might be of any value? If so, who do you advise I contact? Hi Paul It rather depends on the extinguisher and what condition it is in. The original brass or chrome versions made by Pyrene were very popular in vintage cars and boats and were popular for many years so if you have one similar to this type you might try specialist vintage car restoration sites.

I think its a US site. A note of caution in that if it is still charged transporting it through the parcel post could be a little hazardous. They are not pressurised as such but the contents do include acid. I am not sure but it may be worth more intact than discharged to a serious collector or vintage car enthusiast. Hope this points you in the right direction Tony. I have a Pyrene Fire extinguisher that is army green in color and I have been looking for more history on the extinguisher and the Company.

I can not find any more information other then whats above. Where would I be able to find the history? The CTC vaporized and extinguished the flames by creating a dense, oxygen-excluding blanket of fumes, and to a lesser extent, inhibiting the chemical reaction.

In , they patented a small, portable extinguisher that used the chemical. This consisted of a brass or chrome 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. As the container was unpressurized, it could be refilled after use through a filling plug with a fresh supply of CTC. A further variety of extinguishger — the Fire grenade — consisted of a glass bottle filled with the liquid that was intended to be hurled at the base of a fire.

Early ones used salt-water, but later they were filled with CTC. Exposure to high concentrations damages the nervous system and internal organs. Additionally, when used on a fire, the heat converts CTC to Phosgene formerly used as a chemical weapon!!! The reason your extinguisher is Army Green is that it was almost certainly used by the military who tended to paint everything Green or more likely had them made painted green. Carbon Tetrachloride is lethal stuff so if it is still charged be very careful if you are keeping it as an antique.

If in the event you want dispose of it there are collectors or contact your local Environmental Services for advice. Hi, I have an un-used Nu Swift E fire extinguisher. Is this type of extinguisher worth anything? The only reference I can find is in a directory for Aircraft accessories. There are collectors of fire extinguishers both here and in the United States and the brass Pyrene type are popular as they are more decorative and often used in vintage car restoration.

They do not sell for big money. If you go to ebay. There is a Nu-Swift Water extinguisher listed at present. If you follow the bids on this item it will give you an idea what yours is worth. As yours is full it may fetch a little more. If the extinguisher is completely black it may have been used in marine or aviation. Black is the standard colour code for Carbon Dioxide fire extinguishers but modern units are red with a black band.

They specialise in old extinguishers but primarily for use in vintage car restoration. They may be able to help Prices vary considerably depending upon how rare the model is.

Good luck! The only trace I can find is the serial no on it the Internet search also says American navy was only curious as will prob go on the scrap pile as I work for a fire extinguisher company.. Thank you. Hi Ant The American connection fits in with the marine application although i would not set much store by the weight in Pounds. I have a Pyrene that is marked in Quarts!! You could do worse than put it on ebay.

The Americans are great collectors of ships memorabillia and fire extinguishers- you never know. You wont be the only one selling vintage extinguishers on ebay.

Be aware that if you decide to scrap it that it is illegal to dump a pressurised fire extinguisher. As it is CO2 you should be OK to put on a thick pair of gloves to avoid cold burns- and a pair of goggles and discharge in the wide open air. Only takes a few seconds. Otherwise you would have to contact the local Environmental Waste dept for safe disposal.

He there I may put it on eBay and see but I am aware of laws an legisation as I am reg with Ifeda and bafe an also am a licenced carrier. I also aquired a water fire extinguisher today that is the old push top style with the handle running all the way round the top made by geo. Yours sincerely Andrew. There is little information available on the Frowave.

Frowave is on the centre left. A specialist collector I know says there were several models the most popular being a slim tall cylinder. Originally these were painted Red. They have a mild steel canister so needed protection against corrosion.

The British Standard did not change until the late sixties when foam type extinguishers were designated by a Cream colour coding that still applies today. Not that the Frowave contained foam as we know it today as it was a more accurately a foaming chemical mix.

The accepted standard colour at that time was Signal Red which is still used today on fire extinguishers. In those days Signal Red was a recognised colour. French Blue was subsequently used for Powder extinguishers.

Some of the beautiful designs on vintage and antique canisters and cans reminds us of an age when decoration was nearly as important as function. From elegant gold and red and blue decals to tall metal canisters with embossed labels, we love looking at these old unusual treasures.

The Pyrene Company Limited from their beginning in , until when they became Chubb Fire Security Limited, were among the world's leaders in the manufacture of fire fighting equipment. The name Pyrene was epitomised by their famous 'pump' extinguisher which was installed on public transport, commercial and private vehicles throughout the western world. In , a Scottish engineer, unable to get financial backing in the UK, took his idea for a fire extinguisher to the US. He established what became known as the Pyrene Company of Delaware in

Несколькими быстрыми нажатиями клавиш она вызвала программу, именуемую Экранный замок, которая давала возможность скрыть работу от посторонних глаз. Она была установлена на каждом терминале в Третьем узле.

Поскольку компьютеры находились во включенном состоянии круглые сутки, замок позволял криптографам покидать рабочее место, зная, что никто не будет рыться в их файлах. Сьюзан ввела личный код из пяти знаков, и экран потемнел.

Но того человека в очках нигде не. Были другие люди. Празднично одетые испанцы выходили из дверей и ворот на улицу, оживленно разговаривая и смеясь. Халохот, спустившись вниз по улочке, смачно выругался.

Все остальные встретили слова Беккера недоуменным молчанием. - Элементы! - повторил Беккер.

Я подумала, что АНБ его ликвидировало. - Вот. Если АНБ в состоянии вывести пять риолитовых спутников на геостационарную орбиту над Ближним Востоком, то, мне кажется, легко предположить, что у нас достаточно средств, чтобы подкупить несколько испанских полицейских.  - Его доводы звучали волне убедительно. Сьюзан перевела дыхание.

Он жестом предложил старику перешагнуть через него, но тот пришел в негодование и еле сдержался. Подавшись назад, он указал на целую очередь людей, выстроившихся в проходе.

Беккер посмотрел в другую сторону и увидел, что женщина, сидевшая рядом, уже ушла и весь ряд вплоть до центрального прохода пуст. Не может быть, что служба уже закончилась. Это невозможно. Да мы только вошли.
