“…Even those publications point to human error as the dominant cause of OOS test results. 3 Reducing error probability starts with study and classification of the errors, education, and training. Finally, a round-table discussion moderated by Ales Fajgelj allowed everybody to receive answers to their questions, and to learn from the experiences accumulated in other laboratories, and even in other fields (e.g., aviation and medicine).…”

“…Measurement is always subject to errors due to imperfections in human psychomotor activity, low level of manual dexterity, inaccuracy of measuring instruments, choice of inappropriate measuring method or inability to observe constant measurement conditions [11]. Properly reporting an experimental result along with its uncertainty allows other people to make judgments about the quality of the experiment, and it facilitates meaningful comparisons with other similar values or a theoretical prediction.…”

This innovate ve interdisciplinary study deals with influence of fine motor skill level (finger dexterity) of individual on his measurement results in metrology practice. The main objective of this study was determinate fine motor skill level of individuals using a motor test. Further determinate the potential effect of different fine motor skill levels on accuracy of measuring using a mechanical handheld sliding caliper. Fine motor skill test and metrological test were implemented. Pursuant the results of fine motor skill test were probands divided into 2 groups. The groups are significantly different on accuracy of measurement (p=0,006). Pearson coefficient shows a significant correlation r = -0.66 between the Purdue Pegboard test and a measurement error. Results confirmed that the fine motor skill of the upper limbs (especially finger coordination) significantly influence accuracy of measurement using a mechanical handheld sliding caliper.

“…There is an extensive literature on investigating factors leading to human error (human factors) in aviation, engineering, medicine, accident analysis, forensic science and criminal investigations, and other fields [4]. An understanding of human error and the necessity of including this topic in programs for teaching students is now also recognized in analytical chemistry [5][6][7][8].…”

Abstract:The classification, modeling, and quantification of human errors in routine chemical analysis are described. Classifications include commission errors (mistakes and violations) and omission errors (lapses and slips) in different scenarios at different steps of the chemical analysis. A Swiss cheese model is used to characterize error interaction with a laboratory quality system. The quantification of human errors in chemical analysis, based on expert judgments, i.e. on the expert(s) knowledge and experience, is applied. A Monte Carlo simulation of the expert judgments was used to determine the distributions of the error quantification scores (scores of likelihood and severity, and scores of effectiveness of a laboratory quality system against the errors). Residual risk of human error after the error reduction by the laboratory quality system and consequences of this risk for quality and measurement uncertainty of chemical analytical results are discussed. Examples are provided using expert judgments on human errors in pH measurement of groundwater, multiresidue analysis of pesticides in fruits and vegetables, and elemental analysis of geological samples by inductively coupled plasma mass spectrometry.
