Error management method

In the second case study, variation tree analysis and the events and causal factors chart/root cause analysis method are applied to an incident in a resin plant. This case study illustrates the application of retrospective analysis methods to identify the imderlying causes of an incident and to prescribe remedial actions. This approach is one of the recommended strategies in the overall error management framework described in Chapter 8. 

This indicates that error management comprises two strategies proactive methods are applied to prevent errors occurring, and reactive strategies are used to learn lessons from incidents that have occurred and to apply these lessons to the development of preventive measures. Both proactive and reactive methods rely on an understanding of the courses of human error based on the theories and perspectives presented in this book. The tools and tech-... 

Manager error it means manager and engineering technical personnel s mistake. It includes 4 kinds of types. That is. Training is not in place Manager s quality is low the attitude is not correct Management method is not proper. 

The Critical Decision Method, as adapted for this study, involves an interview of approximately one-hour duration for each participant. The interview proper was broken into three major sections, with the Critical Decision Method being used three times to ejqrlore different aspects of the management of error in normal operations as well as training. The three sections of the interview were broadly 1) the management of shps and lapses 2) the management of mistakes and 3) error management from an instructional perspective. 

Such audits may therefore be useful as a method of increasing safety awareness and management commitment to safety as part of a more general attempt to reduce accidents. They should be treated as first steps and management must be prepared to do more than just carry out a safety audit. The authors of safety audits must be prepared to provide guidance on the next steps in error reduction once the problems have been identified. 

Part—I has three chapters that exclusively deal with General Aspects of pharmaceutical analysis. Chapter 1 focuses on the pharmaceutical chemicals and their respective purity and management. Critical information with regard to description of the finished product, sampling procedures, bioavailability, identification tests, physical constants and miscellaneous characteristics, such as ash values, loss on drying, clarity and color of solution, specific tests, limit tests of metallic and non-metallic impurities, limits of moisture content, volatile and non-volatile matter and lastly residue on ignition have also been dealt with. Each section provides adequate procedural details supported by ample typical examples from the Official Compendia. Chapter 2 embraces the theory and technique of quantitative analysis with specific emphasis on volumetric analysis, volumetric apparatus, their specifications, standardization and utility. It also includes biomedical analytical chemistry, colorimetric assays, theory and assay of biochemicals, such as urea, bilirubin, cholesterol and enzymatic assays, such as alkaline phosphatase, lactate dehydrogenase, salient features of radioimmunoassay and automated methods of chemical analysis. Chapter 3 provides special emphasis on errors in pharmaceutical analysis and their statistical validation. The first aspect is related to errors in pharmaceutical analysis and embodies classification of errors, accuracy, precision and makes... 

Biochemical oxygen demand (BOD) is one of the most widely determined parameters in managing organic pollution. The conventional BOD test includes a 5-day incubation period, so a more expeditious and reproducible method for assessment of this parameter is required. Trichosporon cutaneum, a microorganism formerly used in waste water treatment, has also been employed to construct a BOD biosensor. The dynamic system where the sensor was implemented consisted of a 0.1 M phosphate buffer at pH 7 saturated with dissolved oxygen which was transferred to a flow-cell at a rate of 1 mL/min. When the current reached a steady-state value, a sample was injected into the flow-cell at 0.2 mL/min. The steady-state current was found to be dependent on the BOD of the sample solution. After the sample was flushed from the flow-cell, the current of the microbial sensor gradually returned to its initial level. The response time of microbial sensors depends on the nature of the sample solution concerned. A linear relationship was foimd between the current difference (i.e. that between the initial and final steady-state currents) and the 5-day BOD assay of the standard solution up to 60 mg/L. The minimum measurable BOD was 3 mg/L. The current was reproducible within 6% of the relative error when a BOD of 40 mg/L was used over 10 experiments [128].
