Fire Safety
Six people died and several more were severely injured in the 2003 Chicago Loop high rise fire, at the Cook County Administrative Building. Around 2,500 government employees work in the building, which was built in the 1960s and bought by the county in 1996. Officials now believe that many of the fire's casualties could have been prevented had the building fire safety codes been up-to-date and had proper protocols for evacuation been followed by the Chicago Fire Department. Although the building did have an official fire evacuation plan, it was not followed, and although evacuation drills were conducted four times a year, the evacuation procedure was chaotic and disorganized. Conflicts of interest related to political ties between the mayor's office and the building management company may be partially responsible for the building's inadequate safety features such as its lack of a sprinkler system. In addition to the building's safety flaws, miscommunication between building management and the fire department regarding evacuation procedure protocol was a primary cause for the fiasco.
The main problems with the building's safety features include the automatic locking of stairwell doors with no override system; the lack of pressurized stairwells; and the lack of a sprinkler system. The stairwell doors are designed to lock from the inside to prevent intruders. However, in the case of a fire, the automatic locks become a serious hazard preventing persons trapped inside to find safety. Buildings with similar security locks should be installed with a remote override system. All six of the building's casualties were persons trapped in the stairwell.
The lack of pressurized stairwells also contributed to the accumulation of smoke within the stairwells causing many of the victims' deaths and smoke inhalation injuries. A pressurized system would have allowed for the trigger of ventilation systems that would also have whisked smoke away from the area...
(Wolverine Tube Heat Transfer Data Book, 2009) Basic components of Shell and Tube Heat Exchangers include the following basic components although there is a plethora of existing specific features used in design of the Shell and Heat Tube Exchanger. The components specifically are: (1) Tubes -- "...the basic component of the shell and tube exchanger, providing the heat transfer surface between one fluid flowing inside the tube and the other fluid
76). As automation increasingly assumes the more mundane and routine aspects of work of all types, Drucker was visionary in his assessment of how decisions would be made in the years to come. "In the future," said Drucker, "it was possible that all employment would be managerial in nature, and we would then have progressed from a society of labor to a society of management" (Witzel, p. 76). The
Hume's Problem Of Induction David Hume is known as one of the foremost skeptics and humanists of his time, who exalted in mankind's ability to transform the world through science. Somewhat ironically, then, one of his most far-reaching philosophical contributions was to phrase the problem of induction which today is often thought to deny scientific knowledge. Just a couple chapters of a single book, Hume posed a question which has yet
Business Nuclear power, under current conditions, is characterized by much lower regular emissions compared to energy from fossil fuel burning. But, it poses its own unique hazards, of which the most notable is risk of industrial accidents (e.g. Chernobyl) that have acute, long-term repercussions over huge areas. There are also security risks presented by vast inventories of materials that have the potential of being utilized as nuclear weapons; fossil fuels pose
The 1990s also saw innovative interpretation of law enforcement's role in the perpetuation of organized crime. One of the most notable examples is L.A. Confidential (1997), in which corruption has reached so deep into the Los Angeles police department that two seemingly unrelated criminal investigations both lead to the police chief. The genre also proved its adaptability and continued appeal with Heat (1995) and Carlito's Way (1993); both films starred
The Leblanc alkali production processes were especially pernicious, but they followed along the lines of previous industrial processes. In other words, the first British environmental legislation was a response not so much to a qualitative change in industrial processes and their environmental impact but more to a quantitative increase in sources of pollution that had up to that point been (if only barely) tolerable. Legislation Arising From Public Anger At the
