Human Error Assessment

Human error assessment Operator/process and equipment interfaces Administrative controls versus hardware... 

Human Factors—Included here are human error assessment, operator/process and operator/equipment interfaces, and administrative controls versus hardware. 

Human Error Assessment and Reduction Technique (HEART) examines particular task types and their associated error probabilities using tables of task types and faaors which impact on the performance of the task. 

Because there are some minor differences from the OSHA rule, the components of those elements are worthy of further explanation. For example, under human Factors are the following components operator-process/ equipment interface, administrative control versus hardware, and human error assessment. Likewise, under enhancement of process safety knowledge are quality control programs and process safety, professional and trade association programs, the Center for Chemical Ih-ocess Safety (US.) program.

Human error probability assessments using the Human Error Assessment and Reduction Technique (HEART)... 

HEART Human error assessment and reduction technique. Relatively quick to apply, and understood by engineers for quantification of human errors. It is a generic one and has general use. 

Similarly, there many techniques to face and comhat human error such as technique for human error rate prediction (THERE), human error assessment and reduction (HEART), etc. already discussed in previous chapters. 

Various human reliability assessment techniques may be used to evaluate the effectiveness of cross-checking activities - eg THERP (Technique for Human Error Rate Prediction) and HEART (Human Error Assessment and Reduction Technique). It is important that any assessment is made by a competent human reliability specialist and that it is based on information provided by the operators who actually carry out the filling operation. 

HEART Human error assessment and reduction technique... 

For some time there has been an interest in exploring the underlying reasons, as well as probabilities, of human error. As a result there are currently several models, each developed by separate groups of analysts working in this field. Estimation methods are described in the UKAEA document SRDA-Rll, 1995. The better known are HEART (Human Error Assessment and Reduction Technique), THERP (Technique for Human Error Rate Prediction), and TESEO (Empirical Technique to Estimate Operator Errors). 

The Human Error Assessment and Reduction Technique (HEART) structures PSF considerations for the analyst who uses these to modify basic error probabilities. It assumes that human reliability is dependent on the generic nature of the task and that the level of reliability will be consistent (given a likelihood within probabilistic limits) under perfect conditions. The reliability can be varied for non-perfect conditions using Error Producing Conditions (EPCs).

Chapter 9 describes a framework for the identification and quantification of human error in fishing vessel operation, following a brief review of human error assessment techniques. This framework ranks the impact of human error and further integrates the available risk control options into the analysis. The approach uses Analytical Hierarchy Processing (AHP) theory to rank the preference of each control option. The advantages of employing the AHP technique are discussed and the integration of such a technique within the FSA framework is described.

Keywords AHP, decision making, human error, human error assessment... 

The use of the AHP method enables the solutions for each possible human error identified, to be integrated within the analysis. This is unlike the methods reviewed in Section 9.2, where the solutions to reduce the risk levels (posed by human errors) are evaluated in the first instance, and then a re-iteration of the whole analysis is performed (assuming the implementation of the solution) to confirm the risk reduction. An approach using the AHP method for human error assessment and decision making applied to ship operations is presented in Section 9.5. 

This Chter describes a method using AHP to achieve this aim. The approach integrates the risk control option within the human error assessment framework to determine the best option for the identified hazards. The advantages of using the described approach for fishing vessels include ...
