Recommended: Legal Aspect Of Fire
Today we take for granted fire safety. There are rules and regulations to help keep us safe at home, school, work and every public place. Fire extinguishers are one of many health and safety regulations. According to a survey conducted among coworkers and peers, 8 out of 10 people said they own fire extinguishers in their home and have them at their place of work. (Raymond, Sabrina, “Fire Extinguisher Acknowledgment” Survey, July 2017). But what exactly is a fire extinguisher? A fire extinguisher as defined in the Encyclopedia Britannica (September 2014) is a “portable or movable apparatus used to put out small fire by directing onto it a substance that cools the burning material, deprives the flame of oxygen, or interferes with the chemical …show more content…
In 1818 a pressurize cylinder with potassium carbonate was introduced. In 1866 soda-acid was introduced but Francois Carlier. Soda-acid extinguishers were patented in US in 1881 by Almon M. Granger. Both Carlier and Almon both used soda-acid but they used different agents for a chemical reaction. Calier mixed soda-acid with water and tartaric acid, in which doing so created a CO2 gas causing pressure to build and the solution to be released from the cylinder. Granger, used a sulfuric acid and soda-acid to release pressurized water onto the fire. Also in 1881 two Englishmen, Read and Campbell developed an extinguisher geared toward the automotive business called the Petrolex. The Petrolex was a new type of extinguisher, using a CO2 cartridge to expel water based extinguishing agents from a cylinder. In the 1900 more advanced models and the models we know today were produced. The foam extinguisher was first produced by Aleksandr Loran. In the early 1900’s, extinguishing foam, sodium bicarbonate was mixed with aluminum sulfate “usually by inverting the unit” (Bartlett, A., 2017); once combined, carbon dioxide was produced and help to eject the newly formed fire extinguishing agent. Foam units were used to fight flammable liquids, more commonly used in commercial
Disasters can be so impactful; some can forever change the course of history. While many at the time thought this story would soon pass, and with it all the potential bad publicity, the story of the Triangle fire spread quickly, and outraged many people. On a beautiful spring day in March 1911 when 146 workers lost their lives, a fire would prove it could do what years of reformers had failed to do, get the government on the side of the workers. I would argue that the fire largely impacted the country. Specifically, the Triangle Fire ended up changing New York’s interconnected political and economic scene, and spurred on the creation of stricter safety codes. For the first time owners would hold responsibility for their actions. Max Blanck and Isaac Harris; being indicted for manslaughter was proof of this. Social change seemed to be spurred as well; the general public and newspapers would come back the workers of New York. Large institutions would suffer as well. Tammany Hall would be feared less and less by waves of new immigrants. The largest change brought about by the blaze would be legislation. Twenty-five bills, recasting the labor laws of the state
Looking back at how the chemical weaponry expanded starting in the beginning of World War 1, it all began with Tear gas which was used by the French in August of 1914. Those techniques have been used in ancient times. Moving forward eight months in to the war the Germans have been giving great study in to the development of chemical weapons due to the first usage from the French and witnessed its great effectiveness and were the first to use it in a large scale.
'Is it true that long ago firemen put fires out instead of going to start them?’ ‘No. Houses. have always been fireproof, take my word for it.’ ‘Strange. I heard once that a long time ago houses used to burn by accident and they needed firemen to stop the flames.’ He laughed.
First, a fire suppression system must be considered. Specific devices would need to be installed to detect and response to fire, potential fire, or combustion danger (Whitman, pg. 480). These suppression systems work by eliminating environmental elements (temperature, oxygen, and fuel) that are needed for fire to burn. Therefore, the system should include a water mist system to reduce temperature, a CO2 system to remove oxygen and a soda acid system to prevent fuel to a fire.
The French were the first to start experimenting on chemical agents in 1912. They first used it on their people as riot control to capture criminals that who had robbed a bank. They used 26 millimeter grenades filled with chemical agents into the center of the group criminals they were attempting to apprehend. It was not said if it was effective but continued to look into using it for other means. However, the Germans at this time had not been interested in producing any kinds of chemical weapons.
Fire safety education is a crucial aspect of fire prevention. The general public needs to know how big of a threat fire is to them and how they can do things in their everyday lives to improve their safety, as well as preventing the threat of fire to begin with. The commission also realized that it was critically important that people know how to properly act once a fire has started. It is important that people have the knowledge to act quickly, safely, and effectively. When people don’t understand fire they can react in many negative ways such as panicking, not evacuating effectively, or by trying to fight a fire that they are not going to be able to extinguish. All these human reactions can decrease safety and end with tragic results. In the commission’s report they approximate that nearly 70 percent of all building fires were due to people acting carelessly because they did not understand the fire dangers that were present. The commission cited studies like one conducted in southeast Missouri. In the southeast Missouri community, a huge emphasis was put into public fire safety education because the fire death rate of the community was much higher than the national average. After increasing fire safety education in the community it was no surprise that the rate of deaths and injuries decreased
Altho somewhat similar the two stories are very different in many ways. The first story is called “Mystery of Heroism” by Stephen Crane and the other one is “To Build a Fire” by Jack London. Both of the books are part of the short story genre and realism stories. The author's purpose for writing the “Mystery of Heroism” is to tell a story about a brave man who went to get water for a dying man. The purpose for writing “To Build a Fire” is to tell about a man and his dog and how he tried to fight the below freezing temperatures to stay alive. Both authors use realism because they want to tell real stories about people and how they had to overcome struggles in their lifetime. These two stories have similarities but they are way more different than anything else. One of the stories is about a man who has to overcome fear to get water for a man.

Mustard gas was not the only example of chemical weaponry used during World War I. The first example of this was the Germans use of a gas called phosgene in mid-1915, which caused drastic damage to the lungs (Mack 2). The Germans began using mustard gas in 1916 and soon both sides began to use poison gas as a weapon. At a lab at American University, which at its peak employed over 1,200 scientists specifically to create chemical weapons for the war, a new gas called Lewisite was developed. Lewisite poisoned its victims through the skin and rendered gas masks useless against it. During the war as many as 50 different gases were used by both sides (Mack 2). When the war e...
Everyone has their own interpretation of what a firefighter is or does. The dictionaries definition says, “A person who is trained to put fires out, rescue people from fires, educate the public about fire prevention, and help people in other emergencies.” My definition of a firefighter growing up was a person who runs through burning building and found people who are screaming and crying, to save them. Now growing up with the desire to become a firefighter my definition has changed to someone, a women or man, who not only thinks about themselves but about the lives and loved ones of others. Whether it is rescuing people from a burning building, caring for their medical needs, extinguishing fires in a house, large building, or in a vehicle, this profession is about helping others.

In the early stages of the war with the Soviet Union the Einsatzgruppen or know as the "mobile killing squads." the first to find such a method was arthur Nebe, the commander of the Eninsatzgruppen B. His men had been receiving mantle anguish by doing all the kill with guns. They also seemed to have a problem killing young children and woman. That's when the started to look for an alternative way to kill them. The first gas vans were ready in September 1941. They were tasted out on soviet prisoners of war. The second test was attend by two chemists by the names of Dr. Walter Hees and Dr. Theodor Frierich Leidig. Leidig said the following about the gassing at the post war trial in West Germany : " the van was opened some bodies fell out, others were removed by prisoners. As our chemists had predicted, the bodies had the pinkish tinge typical of victims of carbon monoxide poisoning. Fifteen gas vans were in operation in German occupied Soviet territory that's were the Einsatzgruppen put them. Two vans were for the use in Latvia and Estonia and all the areas between those two and the eastern war front.
Flame retardants refer to a class of several chemicals that are used to slow or prevent the ignition or growth of fires. A variation of different chemicals, with diverse properties and structures, are combined in different ways to suit the different types of materials to make them fire-resistant without interfering with their intended use or performance. Since the 1970’s, FRs have been and still are widely added or applied to a big variety of major consumer products.
The first self propelled steam engine pumper was built in New York in 1841. In 1853, Alexander Bonner Latta invented the first practical fire engine. Steam powered fire engines were still in use here and there, up until the 1920 motorized fire trucks became more common by 1910. From 1911, Mack Trucks began producing fire trucks, slowly becoming the most famous manufacturer in this field. In 1911 their was a fire in a ten-story building, the building was used for manufacturing clothing and claimed the lives of 146 employees and were mostly young women who leaped to their death. They thought this building was fireproof but it was
