Analysis of operator human errors in hydrogen refuelling stations: Comparison between human rate assessment techniques

Human reliability assessment (HRA) in maintenance of production process: a case study

“…The cost of maintenance and operations by American manufacturers, for instance, is over 300 billion of dollar each year. It is an alarmingly high cost of engineering systems, which can be significantly reduced by applying a human factor principle during the design and operation phase (Mannan, 2012, Castiglia andGiardina, 2013). Maintenance process of complex industrial technology is noted as being especially vulnerable to human error; and, human error have a high contribution in maintenance cost profile of production plants (Kirwan and Ainsworth, 1992).…”

“…Human errors in maintenance activities may generally lead to incorrect decisions, actions, or checks (Singh and Kumar, 2015). Mannan (2012) and Castiglia and Giardina (2013) demonstrated that human error is the primary causal factor of between 50% and 90% of the accidents in industries. Hence, to reduce the consequences from human error and assure effective maintenance process, precise estimation of the potential human error and their probability of occurrences during the maintenance execution is vital.…”

“…Several methods have been compared and studied in the literature to check the validity and consistency of some developed HRA methods; see e.g. Kirwan (1994), Castiglia and Giardina (2013), Calixto (2012), and Kirwan et al, (1997). These studies considered both the pros and cons of HRA techniques such as SLIM (Success Likelihood Index Method), HEART, and THERP under various scenarios.…”

“…The findings from their analysis confirms the empirical validity of these techniques. Castiglia and Giardina (2013) compared the HEART and CREAM (Cognitive Reliability and Error Analysis Method) technique, by carrying out the HRA of maintenance process of refueling station of the hydrogen storage systems. The results of their comparison demonstrated that the estimated probabilities of human error are significantly close for both techniques.…”

Hydrogen safety risk assessment methodology applied to a fluidized bed membrane reactor for autothermal reforming of natural gas

“…On the other hand, a full deployment of hydrogen as the preferred energy carrier will surely be influenced by the public acceptance of hydrogen mainly based on safety concerns for both production (centralized or distributed) [6,7] and utilization (automotive or residential) [8]. The public perception is definitely influenced by past circumstances of severe accidents with significant economic and societal costs [9].…”
