IntroductionHaving not fully achieved the required standards for the assignment, I have re-worked on the areas pinpointed as not satisfactorily tackled by carrying out in depth study to support my argument. Notably, my initial work was faced with the problem of originality and this has been solved by conducting thorough paraphrasing of materials used. In addition, I have ensured that every material used to compile the current assignment has been listed in the references section and properly in texted as provided by APA system of referencing. Typing and spelling errors were also some of the problems identified in my previous work.
This has been addressed in the current work comprehensively by proofreading my work keenly with a view of ensuring the intended meaning is not distracted. The following sections offer a detailed discussion of areas identified not have met the minimum threshold. PART AQuestion 1The factors to be considered when designing controls and displays on equipment and machineryIn recent years, the total number of work-related accidents as well as ailments has increased significantly. This has been attributed to the human factors. Human factors play a crucial role in aiding to reduce accident occurrence in the workplace.
However, human factors can contribute to accidents in the workplace. These work-related accidents cause loss of time and hence low productivity (Moraes, Arezes & Vasconcelos, 2012, pp. 552). The main industries that are affected by work-related disorders include construction, transportation and warehousing. Research demonstrates that disorders in the workplace can be prevented by putting into consideration the ergonomics criteria, that is, fitting a job to a worker (Angerer, 1985, pp. 45-52). Ergonometric work enables designers to detect potential hazards in the workplace.
In addition, ergonomics analysis determines the malfunctioning and variability in work places. The Bhopal explosion, which occurred in India, is a clear example of how human errors can cause deaths and work-related disorders. Other examples include the Seveso accident in 1976 and Ohio in 1984 (Ball, 2011, pp. 317-322). During the process of chemical reaction, raw materials are combined and reacts together to produce the desired chemical product. However, such chemical reaction process generates heat and this process is known as exothermic reaction. In this vein, there are hazards arising from handling such flammable and toxic chemicals.
According to (Cafazzo, et al. , 2009, pp. 73), exothermic reactions can lead to thermal runaway that occurs when heat generated by chemical reaction exceeds heat put under control. The additional heat heightens temperatures causing reaction rate to increase and accelerate the rate of heat production. Accidents rarely happen at the work place, but in the event they occur, the outcome can be disastrous and tragic. With runaway exothermic reactions emanating from increased temperatures and high pressures, the possibility of explosion occurrence are high.
However, to reduce chances of occurrence of any kind of accident, the following factor must be put into consideration when designing controls and displays on equipment and machinery: Potential for thermal runaway: In cases where occurrence of thermal runaway is more common, safety valves requires to be installed more closely to control the high pressures in the event the heating process generates more heat with the capacity to break the existing few safety valves (Cassano-Piché et al. , 2010, pp. 52). In addition, machinery and equipments used in such high risk process should be installed with display meters to help in monitoring of heat and pressure levels in order to avoid cases of bursting.
