Through out the history of the United States, a number of incidents and disasters have occurred to influence safety and protection. In the aftermath of these events, valuable lessons are learned and steps are taken to ensure nothing like that happens again. One such incident is the Triangle Shirtwaist Factory fire, one of the most influential and horrifying incidents in United States history. The fact that both the National Fire Prevention Association (NFPA) and National Safety Council (NSC) trace their history back to this incident speaks to that. Sadly, the tragic events that unfolded during the Triangle fire were not surprising.
Throughout Zac Unger’s memoir Working Fire the Making of a Fireman he struggles to find a place within the fire station and among coworkers. Unlike many of the fellow recruits who spent years preparing to become a firefighter, Unger an Ivy League grad simply responded to a bus stop ad. After realizing that most recruits were either former military, tradesmen or other firefighter’s kids Unger “Mostly I just stayed quite, tried to down play my existence. I figured if I could just make it through the academy without being called out as a fraud, I’d end up a firefighter like the rest of them”(Unger, 22-23). This distinction between Unger and the rest of the recruits was seen as something to be ashamed of, something to hide away.
T oday, October 8th 2016 is the 145th anniversary of The Great Chicago Fire. The Great Chicago Fire was a massive fire that lit 4 square miles of the city. A major factor in the Great Chicago Fire was the wood. Almost the entire city was built of wood, and wood is very flammable.
The high amount of limestone in the creek neutralized the acid rain that was pouring on the creek. This can also make ph scale go into the alkaline side of the ph scale. The ph scale is healthy, because if it was to acidic it will be unhealthy for the fish. These were some of that factors that were in the
Symbolism is a notable feature in Catching Fire. Through symbolism , Suzanne Collins manages to paint Katniss as the ultimate embodiment of rebellion through transferring her into a mockingjay . " A mockingjay is a creature the Capitol never intended to exist"(92), as it is a result of the Capitol's usage of the japperjays which were sent to spy on the rebels. However, the japperjays failed in their mission so the Capitol left them to die ,but they managed to survive through mating to female mockingbirds . This proves that the existence of the mockingjays is an act of rebellion in itself , an act of defiance excuted by the Capitol's own invention , long before Katniss has been born. .
On 11-14-2015 at about 2106 hours I was dispatched to a domestic violence report at the Emerald Point Condos at 31900 104th AVE SE; H102, Auburn/King/Wa. Enroute dispatch advised the reporting party/victim, Lizbeth Nunez Santana was calling to report that she was assaulted by her husband. The incident occurred about two hours prior and the husband was no longer at the residence. I arrived at the address and contacted Lizbeth and her cousin, Maribel Chavez. Throughout my conversation with Lizbeth it was clear that she was very upset, she had to stop speaking several times as she was crying and upset with the situation.
To better understand the proper water flow requirements for an NFPA 25 fire protection systems (FPS) that is installed within a general purpose assembly e.g. auditorium we have to look at NFPA 14. It was first created and issued in 1912 and provided the layout, design and water flow requirements of the three different standpipe systems (Klaus, 2014). They are Class I, II and III. According to Mettauer (2007), a Class I standpipe system provides a 2 ½ inch hose connection for trained personnel or the fire department to use when responding to a fire emergency.

A report on the effects of Lead and different pH levels on Lemna minor, which is a species of duckweed. The pH of water influences the forms of metals and metal oxide in aquatic systems. This is because pH controls solubility of metals as well as concentration. Decreasing the pH of a solution causes an increase in the free metal ion concentration of the solution. Due to this fact, it was stated that metals in acidic waters have more of a chance of being toxic than metals in neutral water.
This was known because we had an inconsistency in the results by a large margin and then we found water had spilled out of the funnel. Another error or problem was splashing water because of how high the funnel was from the beaker. This problem could be and was resolved by lowering the funnel closer to beaker so there is no splashing to get the most amount of water into the beaker. If the experiment were to be continued then testing more soils would be a way to expand the experiment to find out how permeable and the porosity of different types of soil. More questions that came up during the experiment was how much water was absorbed into the coffee filter and if it would effect my experiment results.
The documentary “Fire in the Blood” directed by Dylan Gray is a shocking expose of pharmaceutical companies which use patent laws to keep profits extremely high even at the cost of so many lives. Giving priority to the company’s profits over the betterment of the people, they didn’t provide affordable ARV’s to the patients. Millions died due to AIDS in Africa when medicines could have been made available to them. Even when the medicines were affordable and many lives would have been saved, the western pharmaceuticals lobby made it impossible. Advertised with the tag line “medicine monopoly malice”, it talks of how big Western pharmaceutical companies block the access to low-cost anti-AIDS drugs for the world’s poorest, causing a holocaust of 10 million deaths.
The Best Story So Far:”To Build A Fire” The best short story that I’ve read so far in class is “To Build A Fire” by Jack London. The story is about an unnamed man during during a really cold day in Alaska. The man sets off with his dog and a lunch and heads for the cabin on Henderson Creek to meet up with the boys. Well, along the way the man doesn't recognize the significance of some of his observations like the cold and falls into a creek which delays him on his trip.
The chemical equation for this experiment is hydrochloric acid + sodium thiosulphate + deionised water (ranging from 25ml to 0ml in 5ml intervals) sodium chloride + deionised water (ranging from 25ml to 0ml in 5ml intervals) + sulphur dioxide + sulphur. As a scientific equation, this would be written out as, NA2S2O3 + 2HCL + H2O (ranging from 25ml to 0ml in
III Types of fire retardants Numerous chemicals having different structure and physical properties could impart fire resistant characteristics when used alone or in combinations. Combinations of different fire retardants with varying proportions can produce an additive, synergistic or antagonistic effect. The synergy of combining fire retardant chemicals has gained considerable practical importance as they are usually less expensive [13, 20]. Fire retardant chemicals can be either chemically bonded reactive type or the additive type where the retardant is applied as coating to the base material and the retention of retardant is by weak secondary bonding and not covalent bonding unlike the former [13,20].
