Anti-flash Gear
Anti-flash gear, also known simply as flash gear, is basic personal protective equipment consisting of a fire-resistant hood and fire-resistant gloves, nowadays often made of Nomex. Anti-flash gear protects to the head, neck, face and hands from short-duration flame exposure and heat. This equipment is donned by shipboard navy personnel whenever a fire breaks out or during periods of heightened readiness. History Anti-flash gear was introduced in the Royal Navy following the Battle of Jutland during the First World War, when a number of British warships had been destroyed or damaged by flash from burning cordite propellant passing through the shell handling room into the magazine. It was found that the anti-flash hoods and gloves were more effective if flame-proofed with borax or boric acid Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula . It may also be called hydrogen orthoborate, trihydroxidoboron or boracic acid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Personal Protective Equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomex
Nomex is a trademarked term for an inherently flame-resistant fabric with meta-aramid chemistry widely used for industrial applications and fire protection equipment. It was developed in the early 1960s by DuPont and first marketed in 1967. The fabric is often combined with Kevlar to increase its resistance for breakage or tear. Properties Nomex and related aramid polymers are related to nylon, but have aromatic backbones, and hence are more rigid and more durable. Nomex is an example of a '' meta'' variant of the aramids (Kevlar is a '' para'' aramid). Unlike Kevlar, Nomex strands cannot align during filament polymerization and have less strength: its ultimate tensile strength is . However, it has excellent thermal, chemical, and radiation resistance for a polymer material. It can withstand temperatures of up to . Production Nomex is produced by condensation reaction from the monomers ''m''-phenylenediamine and isophthaloyl chloride. It is sold in both fiber and s ...

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Battle Of Jutland
The Battle of Jutland () was a naval battle between Britain's Royal Navy Grand Fleet, under Admiral John Jellicoe, 1st Earl Jellicoe, Sir John Jellicoe, and the Imperial German Navy's High Seas Fleet, under Vice-Admiral Reinhard Scheer, during the First World War. The battle unfolded in extensive manoeuvring and three main engagements from 31 May to 1 June 1916, off the North Sea coast of Denmark's Jutland Peninsula. It was the largest naval battle and only full-scale clash of battleships of the war, and the outcome ensured that the Royal Navy denied the German surface fleet access to the North Sea and the Atlantic for the remainder of the war. Germany avoided all fleet-to-fleet contact thereafter. Jutland was also the last major naval battle, in any war, fought primarily by battleships. Germany's High Seas Fleet intended to lure out, trap, and destroy a portion of the British Grand Fleet. The German naval force was insufficient to openly engage the British fleet. This was par ...

Cordite
Cordite is a family of smokeless propellants developed and produced in Britain since 1889 to replace black powder as a military firearm propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance. These produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives. The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target, but not so quickly as to routinely destroy the barrel of the gun. Cordite was used initially in the .303 British, Mark I and II, standard rifle cartridge between 1891 and 1915. Shortages of cordite in World War I led to the creation of the "Devil's Porridge" munitions factory ( HM Factory, Gretna) on the English–Scottish border, which produced around 800 tonnes of cordite per week. The UK also imported some United States–developed smokeless ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magazine (artillery)
A magazine is an item or place within which ammunition or other explosive material is stored. The word is taken originally from the Arabic word ''makhāzin'' (مخازن), meaning "storehouses", via Italian and Middle French. The term is also used for an ammunition dump, a place where large quantities of ammunition are stored for later distribution. This usage is less common. Field magazines In the early history of tube artillery drawn by horses (and later by mechanized vehicles), ammunition was carried in separate unarmored wagons or vehicles. These soft-skinned vehicles were extremely vulnerable to enemy fire and to explosions caused by a weapons malfunction. Therefore, as part of setting up an artillery battery, a designated place would be used to shelter the ready ammunition. In the case of batteries of towed artillery the temporary magazine would be placed, if possible, in a pit, or natural declivity, or surrounded by sandbags or earthworks. Circumstances might requ ...

Borax
The BORAX Experiments were a series of safety experiments on boiling water nuclear reactors conducted by Argonne National Laboratory in the 1950s and 1960s at the National Reactor Testing Station in eastern Idaho.Light Water Reactor Technology Development Argonne National Laboratory They were performed using the five BORAX reactors that were designed and built by Argonne. BORAX-III was the first nuclear reactor to supply electrical power to the grid in the United States in 1955. Evolution of BORAX This series of tests began in 1952 with the construction of the BORAX-I |
Boric Acid
Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula . It may also be called hydrogen orthoborate, trihydroxidoboron or boracic acid. It is usually encountered as colorless crystals or a white powder, that dissolves in water, and occurs in nature as the mineral sassolite. It is a weak acid that yields various borate anions and salt (chemistry), salts, and can react with Alcohol (chemistry), alcohols to form borate esters. Boric acid is often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other boron compounds. The term "boric acid" is also used generically for any oxyacid of boron, such as metaboric acid and tetraboric acid . History Orthoboric acid was first prepared by Wilhelm Homberg (1652–1715) from borax, by the action of mineral acids, and was given the name ("sedative salt of Homberg"). However, boric acid and borates have been used since the time of the ancient Greece, anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
