Fire Fighting
Firefighting is a profession aimed at controlling and extinguishing fire. A person who engages in firefighting is known as a firefighter or fireman. Firefighters typically undergo a high degree of technical training. This involves structural firefighting and wildland firefighting. Specialized training includes aircraft firefighting, shipboard firefighting, aerial firefighting, maritime firefighting, and proximity firefighting. Firefighting is a dangerous profession due to the toxic environment created by combustible materials, with major risks being smoke, oxygen deficiency, elevated temperatures, poisonous atmospheres, and violent air flows. To combat some of these risks, firefighters carry self-contained breathing apparatus. Additional hazards include falling (accident), falls – a constant peril while navigating unfamiliar layouts or confined spaces amid shifting debris under limited visibility – and structural collapse that can exacerbate the problems encountered in a toxi ...

Aircraft Firefighting
Aircraft rescue and firefighting (ARFF) is a type of firefighting that involves the emergency response, mitigation, evacuation, and rescue of passengers and crew of aircraft involved in aviation accidents and incidents. Airports with scheduled passenger flights are obliged to have firefighters and firefighting apparatus on location ready for duty any time aircraft operate. Airports may have regulatory oversight by an arm of their individual national governments or voluntarily under standards of the International Civil Aviation Organization. Duties Due to the Mass casualty incident, mass casualty potential of an aviation emergency, the speed with which emergency response equipment and personnel arrive at the scene of the emergency is of paramount importance. Their arrival and initial mission to secure the aircraft against all hazards, particularly fire, increases the survivability of the passengers and crew on board. Airport firefighters have advanced training in the applic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Inside An Abandoned Convent In Massueville, Quebec, Canada
Fire is the rapid oxidation of a fuel in the exothermic chemical process of combustion, releasing heat, light, and various reaction Product (chemistry), products. Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point temperature. Flames from hydrocarbon fuels consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen. If hot enough, the gases may become ionized to produce Plasma (physics), plasma. The color and Intensity (heat transfer), intensity of the flame depend on the type of fuel and composition of the surrounding gases. Fire, in its most common form, has the potential to result in conflagration, which can lead to permanent physical damage. It directly impacts land-based ecological systems worldwide. The positive effects of fire include stimulating plant growth and maintaining ecological balance. Its negative effects include hazards to life and property, atmospheric pollution, and water ...

Firemen In Action
A firefighter (or fire fighter or fireman) is a first responder trained in specific emergency response such as firefighting, primarily to control and extinguish fires and respond to emergencies such as hazardous material incidents, medical incidents, and emergencies that require response from the public that threaten life, property and the environment, as well as to rescue persons from confinement or dangerous situations and preserve evidence. Firefighters may also provide ordinance regulations, safety requirements, and administrative public functions for the communities and areas they are subject to jurisdiction to. Male firefighters are sometimes referred to as firemen (and, less commonly, female firefighters as firewomen). The fire department, also known in some countries as the fire brigade or fire service, is one of the three main emergency services. From urban areas to aboard ships, firefighters have become ubiquitous around the world. The skills required for safe oper ...

Wallechinsky, David
David Wallechinsky (born David Wallace, February 5, 1948) is an American popular historian and television commentator, the co-founder and past president of the International Society of Olympic Historians (ISOH) and the founder and editor-in-chief of AllGov.com and worldfilmreviews.us. Early life Wallechinsky was born in Los Angeles to a Jewish family, the son of writer Sylvia Kahn and the author and screenwriter Irving Wallace. His younger sister was fellow author Amy Wallace, a "witch" of Carlos Castaneda who co-wrote many books with him and their father and authored ''Sorcerer's Apprentice: My Life with Carlos Castaneda'' in 2003. One day, after he got off an airplane in Britain, the customs officer looked at his passport and remarked, "Ah Wallace, a good Scottish boy coming home." Disquieted, back in the States he discovered that the original family name was Wallechinsky and he adopted that moniker. He was educated at Palisades High School in Pacific Palisades, Los Angele ...

Augustus
Gaius Julius Caesar Augustus (born Gaius Octavius; 23 September 63 BC – 19 August AD 14), also known as Octavian (), was the founder of the Roman Empire, who reigned as the first Roman emperor from 27 BC until his death in AD 14. The reign of Augustus initiated an Roman imperial cult, imperial cult and an era of regional hegemony, imperial peace (the or ) in which the Roman world was largely free of armed conflict. The Principate system of government was established during his reign and lasted until the Crisis of the Third Century. Octavian was born into an equites, equestrian branch of the plebeian Octavia gens, Octavia.

Ancient Rome
In modern historiography, ancient Rome is the Roman people, Roman civilisation from the founding of Rome, founding of the Italian city of Rome in the 8th century BC to the Fall of the Western Roman Empire, collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (50927 BC), and the Roman Empire (27 BC476 AD) until the fall of the western empire. Ancient Rome began as an Italic peoples, Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually controlled the Italian Peninsula, assimilating the Greece, Greek culture of southern Italy (Magna Graecia) and the Etruscans, Etruscan culture, and then became the dominant power in the Mediterranean region and parts of Europe.

Richard Newsham
Richard Newsham (died 1743) was an England, English inventor. He took out two patents for fire engines in 1721 and 1725 (Royal Patent Office 1721 patent #439 and 1725 patent #479) and soon dominated the fire engine market in England. The engine had two single-acting pistons and an air vessel placed in a tank which formed the frame of the machine. The pump was worked by people at the long cross handles. At the front of the engine, protected by a sheet of horn and a door, were directions for keeping the machine in order. The cistern could hold about of water pumping up to a minute. New York City imported its first two fire engines from Newsham in 1731. In 1737 Newsham made a manual fire pump for the Parish of Bray in Berkshire. When Richard Newsham died in 1743 the company was willed to his son Lawrence Newsham. When Lawrence died in 1747 he bequeathed the company to his widow and his cousin George Ragg and the company became Newsham and Ragg. See also * Fire apparatus * History ...

Syringe
A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the front (open) end of the tube. The open end of the syringe may be fitted with a hypodermic needle, a nozzle or tubing to direct the flow into and out of the barrel. Syringes are frequently used in clinical medicine to administer injections, infuse intravenous therapy into the bloodstream, apply compounds such as glue or lubricant, and draw/measure liquids. There are also prefilled syringes (disposable syringes marketed with liquid inside). The word "syringe" is derived from the Greek σῦριγξ ('' syrinx'', meaning "Pan flute", "tube"). Medical syringes Medical syringes include disposable and safety syringes, injectio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Force Pump
A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston. Piston pumps can be used to move liquids or compress gases. They can operate over a wide range of pressures. High pressure operation can be achieved without adversely affecting flow rate. Piston pumps can also deal with viscous media and media containing solid particles. This pump type functions through a piston cup, oscillation mechanism where down-strokes cause pressure differentials, filling of pump chambers, where up-stroke forces the pump fluid out for use. Piston pumps are often used in scenarios requiring high, consistent pressure and in water irrigation or delivery systems. Types The two main types of piston pump are the lift pump and the force pump. Both types may be operated either by hand or by an engine. Lift pump In a lift pump, the upstroke of the piston draws water, through a valve, into the lower part of the cylinder. On the downstroke, water passes th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ctesibius
Ctesibius or Ktesibios or Tesibius (; BCE) was a Greek inventor and mathematician in Alexandria, Ptolemaic Egypt. Very little is known of Ctesibius' life, but his inventions were well known in his lifetime. He was likely the first head of the Museum of Alexandria. He wrote the first treatises on the science of compressed air and its uses in pumps (and even in a kind of cannon). This, in combination with his work ''On pneumatics'' on the elasticity of air, earned him the title of "father of pneumatics." None of his written work has survived, including his ''Memorabilia,'' a compilation of his research that was cited by Athenaeus. Ctesibius' most commonly known invention today is a pipe organ (hydraulis), a predecessor of the modern church organ. Inventions Ctesibius was the son of a barber, born BCE, probablybut not certainlyin Alexandria. He began his career as a barber, following his father. During this first career, he invented a counterweight-adjustable mirror. Another ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
