Recommended: Research background of jet fires

1.1 Research Background Jet fires occur following the ignition and combustion of flammable fluids issuing continuously from a vessel, pipe or orifice, which burn close to the release plane. Jet fires dissipate thermal radiation away from the flame’s visible boundaries. The energy transmitted could be hazardous to both life and property. The pressure of release generates a long flame, which is stable under most conditions. A flash flame may take the form of jet flame on reaching the spill point. The duration of the jet fire is determined by the release rate and the capacity of the source. Flame length increases directly with flow rate. Typically a pressurized release of 8kg/s would have a length of 35m. The cross winds also affects the flame …show more content…

The principal situations in which flames occur by design are in burners and flares. Ejection of flammable fluid from a vessel, pipe or pipe flange can give rise to a jet flame if the material ignites. An intermediate situation, and one which particularly concerns the designer is where the jet flame result from ignition of flammable material vented from a pressure relief valve (Tong, Lo, Zhang &Chen, 2013). Scenario involving jet flames are not easy to handle, since a large jet flame may have a substantial reach, sometimes up to 50 m or more. Jet flames have been involved in a number of accidents, perhaps the most dramatic were the large jet flames from the gas riser on the Piper Alpha Oil platform. In other cases jet flames from pressure relief valves have caused adjacent vessels to overheat and burst, giving a boiling liquid expanding vapour explosion or BLEVE (Tong, Lo, Zhang &Chen, …show more content…

Jet fire hazards should be evaluate seriously as this type of fire could be the initiating event to the large explosion (Joaquim Casal, Mercedes Gómez-Mares, Miguel Muñoz, Adriana Palacios, 2012). However, due to lack of improvement in development of risk assessment tool to evaluate jet fire hazards, the risk analysis cannot be conducted efficiently. Thus this lead to poor risk assessment evaluation. In response to this matter, it is important to develop a comprehensive risk assessment tool for jet fire hazards as to help a better understanding on the related matter. The risk assessment tool will be applying the validated jet fire model which is THORNTON

In Cleveland, Ohio there was a fire that occurred on June 22, 1969, around 12pm on the Cuyahoga river. People called it the “burning river”. The river caught on fire because there were floating pieces of debris that was slicked with oil. The debris ignited by sparks that came from a train that was passing over the river. The reason it happened is from years of people dumping pollution into the river.

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.

“Brush Fire” by Linda Thomas and “Santa Ana” by Joan didion are essays written about the Santa Ana winds of southern California. These malevolent winds start as a cool high pressure front in the Great Basin east of California. As the wind from the high pressure system fall down the back side of the mountains east of southern California. As the winds fall down the west side of the mountains they are warmed by the desert and sun and increase in temperature and speed as they wind through the narrow mountain passes and canyons producing an extremely hot dry wind that torments Southern California and northern Baja Mexico. Both Thomas and Didion have different views on the wind they seem to agree on one thing, that everyone knows when the winds are

Sherpa fire in Santa Barbara grows to 4,000 acres overnight, putting about 140 homes at risk and closing down major freeways according to federal officials. The fire started on Wednesday afternoon on coastal hills north of Santa Barbara. It had moved through overgrown hillsides and canyons that have not been burned in over 60 years because of the hot and dry weather and notorious “sundowner” winds. Sundowners, similar to Santa Ana winds, fuel many of the fires in the Santa Barbara County.

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. .

In April 2013, Matthew Yglesias, an American Economics Journalist proposed the people of Bangladesh would not appreciate having stronger safety standards in their country because it would cause undue harm economically. He asserts Bangladesh should have different lower standards for safety because they are a poorer country. Most of the people involved in the New York tragedy of 1911 also known as the Triangle Fire, would not agree with Matthew Yglesias on his assertion that lower economic status would be an indication of lower safety standards in factories. Namely, the workers, the union leaders, the progressive reformers and the political leaders would all vote for higher standards commiserate with the United States. The only ones who would not argue with Yglesias are the owners of the Triangle Factory with their vested interest, their own problems of multiple fires and accusations of safety neglect.

In the film Escape Fire the Fight to Rescue American Healthcare, there were many insightful examples of why our Unites States healthcare revolves around paying more and getting less. The system is designed to treat diseases rather than preventing them and promoting wellness. In our healthcare industry, there are many different contributors that provide and make up our system. These intermediaries include suppliers, manufacturers, consumers, patients, providers, policy and regulations. All these members have a key role in the functionality of the health care industry; however, each role has its positives and negatives.
