Firefighter's Helmet
For centuries, firefighters have worn helmets to protect them from heat, cinders and falling objects. Although the shape of most fire helmets has changed little over the years, their composition has evolved from traditional leather to metals (including brass, nickel and aluminum), to composite helmets constructed of lightweight polymers and other plastics. Leather helmets The original American fire helmet was created by a New York City luggage maker who was also a volunteer fireman in the 1830s, seeking a better design more tailored to the unique requirements for firefighting than the "stovepipe" "helmets" then in use. Stovepipe was essentially a top hat made of stiff leather with painted design to identify fire company and provided no protection.Leather was chosen as the preferred material both because it was what the man, Henry Gratacap, was familiar with, but also because thick treated leather was flame-resistant and highly resistant to breaking apart. ''Leatherhead'' is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Helmets HallFlame
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and property, atmospheric pollution, and water contamination. If fire re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glycerin
Glycerol (), also called glycerine in British English and glycerin in American English, is a simple triol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in lipids known as glycerides. Because it has antimicrobial and antiviral properties, it is widely used in wound and burn treatments approved by the U.S. Food and Drug Administration. Conversely, it is also used as a bacterial culture medium. It can be used as an effective marker to measure liver disease. It is also widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations. Because of its three hydroxyl groups, glycerol is miscible with water and is hygroscopic in nature. Structure Although achiral, glycerol is prochiral with respect to reactions of one of the two primary alcohols. Thus, in substituted derivatives, the stereospecific numbering labels the molecule with a "sn-" prefix before the stem name of the m ...

Merryweather & Sons
Merryweather & Sons of Clapham, later Greenwich, London, were builders of steam fire engines and steam tram engines. The founder was Moses Merryweather (1791–1872) of Clapham, who was joined by his son Richard Moses (1839–1877). Fire appliances The Merryweathers worked with the engineer Edward Field to fit his design of a vertical boiler onto a horse-drawn platform. They successfully applied it for use in their steam fire engine, thus improving water pressure and making easier to use once steam had been got up. It was reckoned that an engine could get up enough pressure to pump within ten minutes of a call out; the fire could be started before leaving the fire station so there would be enough pressure by the time they arrived at the scene of the fire. Appliances were available in small sizes suitable for a country house, pumping about 100 gallons per minute, through to large dockyard models, rated at 2000 gallons per minute. A common size, popular with Borough fire brigad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dragoon
Dragoons were originally a class of mounted infantry, who used horses for mobility, but dismounted to fight on foot. From the early 17th century onward, dragoons were increasingly also employed as conventional cavalry and trained for combat with swords and firearms from horseback. While their use goes back to the late 16th century, dragoon regiments were established in most European armies during the 17th and early 18th centuries; they provided greater mobility than regular infantry but were far less expensive than cavalry. The name reputedly derives from a type of firearm, called a ''dragon'', which was a handgun version of a blunderbuss, carried by dragoons of the French Army. The title has been retained in modern times by a number of armoured or ceremonial mounted regiments. Origins and name The establishment of dragoons evolved from the practice of sometimes transporting infantry by horse when speed of movement was needed. In 1552, Alexander Farnese, Duke of Parma ...

Dragoon Helmet
A dragoon helmet was an ornate style of metal combat helmet featuring a tall crest; they were initially used by dragoons, but later by other types of heavy cavalry and some other military units. Originating in France in the second half of the 18th century, it was widely imitated by other European armies and was last used in combat in 1914. Some military units continue to wear this style of helmet for parades and other ceremonial duties. History 18th century European dragoon cavalry generally wore tricorn hats, but in 1762, the French Army introduced a new uniform for their dragoon regiments, featuring a crested helmet, loosely based on classical Ancient Greek and Roman styles. It was made of steel with a brass crest and featured an imitation panther fur "turban" and a long black horsehair mane or plume. One distinctive example of this kind of headgear used to be the Tarleton helmet. By the end of the century, it had developed a taller, more elegant shape and a removable feather p ...

Sapeurs-pompiers
The fire service in France is organised into local fire services which mostly cover the Departments of France, with a few exceptions. There are two types of fire service: *The Paris Fire Brigade (Army) and Marseille Naval Fire Battalion (Navy) are military units providing fire protection to Paris and Marseille. *The rest of France has civilian fire services organized, supervised and trained by the French Ministry of the Interior; specifically, they fall under the Civil Defence and Security Directorate (''Direction Générale de la Sécurité Civile et de la Gestion de Crise'', DGSCGC). There are approximately 246,900 fire service personnel in France operating 15,642 emergency vehicles out of 6,894 emergency centres. In addition to providing fire protection and rescue, the French fire service is also one of the providers of emergency medical services. In French, firefighters are known as sapeurs-pompiers or informally as pompiers. The former originally refers to the military-base ...

Brooklyn Fire Department
The Brooklyn Fire Department (BFD) was a professional fire department that provided fire protection and rescue services to the city of Brooklyn, New York, within modern-day New York City, from 1869 to 1898. The Brooklyn Fire Department, a paid firefighting force, replaced a 3,000-person volunteer fire department that was poorly equipped to serve Brooklyn's growing population. The Brooklyn Fire Department consisted of 13 engine companies and 6 ladder companies, as well as two fire boats. A headquarters building was built in Downtown Brooklyn in 1894. and several firehouses were built in the mid-1890s when Brooklyn annexed several smaller towns. The Brooklyn Fire Department was subsumed into the New York City Fire Department (FDNY) in 1898, upon Brooklyn's consolidation with New York City. History Initially, the city of Brooklyn was covered by several volunteer fire departments, mostly close to the shore of the East River, where there were relatively high land values that c ...
