Knowledge competency levels

Knowledge deep level comprehension of any one or all aspects or dimensions of systems competence (such as managing the interrelatedness of systems elements, how complex adaptivity impacts risk mitigation results, how to use system metrics for improvement), and... 

The skills and knowledge required to implement any of the activities of the safety life cycle relating to the safety instrumented systems should be identified and for each skill, the required competency levels should be defined. Resources should be assessed against each skill for competency and also the number of people per skill required. When differences are identified, development plans should be established to enable the required competency levels to be achieved in a timely manner. When shortages of skills arise, suitably qualified and experienced personnel may be recruited or contracted. 

Levels of professional expertise must be qualified according to their complex knowledge bases and paradigms. At different levels, besides the number of cognitive schemes, the jargon, the extent of consciousness of thinking can vary from profession to profession. The number of competency levels worthy of distinction may also vary by professional fields. 

Therefore, it is better to go for specification of competence level for a well-organized company. Knowledge, experience, training, and qualification are major attributes for competence level to be considered. The reader may refer Clause 8.2.9, Table 4, and 5 of Clause 8.2.18 lEC 61508-1 2010 for further details in this regard. From the discussions so far, it has been found that various types of failure play a great role m assessing SIF or SIS. So, better to address various kinds of failures and how to address them ... 

In addition to reducing performance efficiency, the employment of operators with substandard competence levels within safety-critical systems can have grave consequences. For example, a review of major accidents in the hazardous industries indicated that a lack of operator skills and/or knowledge led to the errors that contributed to the accidents analyzed (Wright et al., 2003). Wright et al. (2003) also referred to the Southall rail crash, the Piper Alpha oil rig disaster, the Longford Esso Gas plant explosion, and the Hickson Welch fire as examples of incidents where staff incompetence played a part and where staff competency levels were not sufficiently tested by the organizations involved. 

Fortunately, not all problem-solving tasks in science require the degree of lateral and inventive thinking needed to play championship-level chess. If the area of knowledge in which the computer is required to make deductions and provide advice is not unmanageably large, computers can not only compete with human performance, they can surpass it. 

Many of the facts in the system are shared by several subproblems, and subproblems must be. developed by starting at the top of the hierarchy and working down. Other than these stipulations, they are independent problems. Each branch of the tree can be used independently, and need not be complete to be useful in the formulation study. The expert system s competence on each subproblem can be judged independently. In many cases different experts are used to develop the knowledge bases for different subproblems. Figure 1 shows the structure of the problem, tracing one branch from each level. 

Decide on the selected reader s level of technical competence and then be consistent in writing to tbat level. Assume the reader has a certain minimum knowledge of chemical process safety. 

That means more than simply performing at your present level of competence. It means remed)hng any lack of knowledge or skill and handling any inner or outer block that is an impediment to achievement. It means deplo)dng your talents and capabilities to best advantage. All this may require considerable self-searching, which is the subject of the next chapter. 

The toxicological implications in the effect of the respiratory poisons on the enzyme systems of mammals are not fully comprehended, even at this stage of knowledge. For instance, Dixon and Webb (44) point out that the respiration of most animal tissues is insensitive to carbon monoxide which, in the blood, competes with oxygen for the reduced hemoproteins whereas cyanide has a broad inhibitory spectrum which includes various oxidative systems at cellular level and, most importantly, the oxidized forms of the hemoproteins, especially methemoglobin. In this latter connection, phenazine methosulfate has recently been found effective as an experimental therapeutic in cyanide poisoning of mice (13). The respiratory poisons have just been reviewed by Hewitt and Nicholas (72). 

Hazardous materials specialist Responds with and provides support to hazardous materials technicians, but has advanced knowledge of hazardous materials. Requires 24 hours of Level 3 training and proven competencies, along with advanced instruction, on all specific hazardous material topics. 

Assess, based on national expected competencies outlined, one s own knowledge level related to disaster response and mass casualty preparedness.
