Quiz on Engineering Design - Essay Example Assessment of use - decide on the purpose into which the building falls affects the calculation occupant capacity, especially where the actual population density is not known, an has implications for allowable travel distances and width of escape stairs. Calculation of occupant capacity - it is necessary to assess the number of people who are likely to be present in the different parts of the building. Assessment of escape routes and travel distances - check maximum travel distances from scaled floor plans. Assessment of number and widths of storey/room exits - Check that assumed numbers and widths of exits can cater for expected occupant numbers at each level. Access the need for protection and/or separation of escape routes - Establishment of the identified horizontal escape route need to be fire protected or separated form other parts of the building. 6. Why is it important to perform fire tests Answer: A fire test is a means to determine if a fire protection product would meet the minimum performance as set out by the building code. The consideration of fire testing is very important for the applicable intentions for product specification and product certification. It is also a prudent act to test products to ensure ease of use and the broad, economical applications with regards to its listing and approval use and the compliance. Fire test is also a means to gather data and information in order to understand a specific Hazard such as construction or storage configuration. 7. Why is it important to carry out more than one experiment to test the same parameter Answer: It is very important to carry out more that one experiment to test the same parameter In order to make sure that the object... B5 Access and Facilities for the Fire Service - This defines the requirements which ensure Adequate access to, and within , the building in order to fight fire. This makes no specific requirements relating to glazing, although it does refer to B5 5588. Assessment of use - decide on the purpose into which the building falls affects the calculation occupant capacity, especially where the actual population density is not known, an has implications for allowable travel distances and width of escape stairs. Access the need for protection and/or separation of escape routes - Establishment of the identified horizontal escape route need to be fire protected or separated form other parts of the building. Answer: Trench Effect is a combination of two well understood but separate ideas. The trench effect occurs when a fire burns next to a steepy-inclined surface. The flames are down along the surface, and it heats up the material farther going up. These will emit gases, reach the auto ignition temperature, then start burning. The flames from these area are subject to the Coanda effect and blow a jet of flame up to the end of the inclined surface. Answer

The Nurses' Role in the Prevention of Healthcare-associated Infections Essay

The Nurses' Role in the Prevention of Healthcare-associated Infections - Essay Example The introduction is followed by an explanation of what prevention strategies must be adopted by nurses, in order to prevent the occurrence and transfer of infection in the healthcare setting. Important strategies like hand hygiene, antiseptic technique, disinfectant usage, and removal of unnecessary devices from the healthcare setting are discussed. The report is summarized in a concluding paragraph; and, APA referencing style has been used properly throughout the paper. Introduction Nurses’ role in infection prevention cannot be denied, as they have manifold opportunities of practicing their nursing skills and knowledge to prevent hospital acquired infections. They can help the patient to recover fast by diminishing the complications of the infection. Benson and Powers (2011, p.36, par.1) write in their article: According to the CDC, hospital-acquired infections (HAIs) account for an estimated 1.7 million infections and 99,000 associated deaths each year in American hospitals . A recent study found HAIs to be the sixth leading cause of death in the United States, costing the healthcare industry $6 billion annually. This situation has made the health care providers concerned about the provision of high quality health related services to the patients, so that patient safety may be ensured. Nurses are those professionals who have the opportunity of providing health care services and preventing infections right at the bedside of the patients, thus, having a direct impact upon their health, safety, morbidity, and mortality. Within a multidisciplinary healthcare team, nurses utilize nursing-sensitive indicators to prevent infections. This helps them acquire nursing-sensitive positive outcomes, in the form of changes in patients’ understanding of infection symptom and associated emotional suffering. Nurses lead the entire team in preventing infections through utilization of a myriad of strategies described below. Infection Prevention Strategies Nurses ma y help in infection prevention through utilization of strategies that are effective enough to ensure patient safety. One such strategy is hand hygiene. Nurses should not only practice hand hygiene themselves, but should also encourage the patients to adopt it. Nurses’ hands are the direct transfer path of infective pathogens from them to patients, from where these travel across patients and finally across the whole healthcare environment. Last year, I was admitted to a hospital, and my nurse would always perform hand hygiene before and after every patient contact. He would also perform regular antiseptic technique, which prevented the infection from transferring from the equipment to the patients. I drew the conclusion that antiseptics minimized the contamination caused by pathogens when the nurse started a peripheral I.V. line or rubbed the core of an I.V. connector prior to injection. Antiseptic usage ensured the absence of pathogen organisms responsible for infection. Anot her important technique is to clean and disinfect the nursing-related equipment and tools, like sterilization. Since the medical tools are applied on multiple patients, it is important for nurses to clean and disinfect them as frequent as possible, so as to prevent the transfer of infection. Dust and pathogens collect on environmental surfaces which, if not
