Use of a nominal group technique in the exploration of safety hazards arising from the outsourcing of aircraft maintenance
This study sets out to identify hazards that are likely to occur when airlines outsource aircraft maintenance operations, as well as the causes of these hazards and their impact on safety. Qualitative research design was preferred for the purpose of this study, where the data was collected through a nominal group technique with the participation of subject experts selected by purposive sampling. The inductive approach was adopted for data analysis. The study reveals thirteen themes that may potentially affect aviation safety. The outsourcing of aircraft maintenance by airlines in order to lower maintenance costs and to red...

Calibrating experts’ probabilistic assessments for improved probabilistic predictions
Publication date: October 2019Source: Safety Science, Volume 118Author(s): A.M. Hanea, G.F. NaneAbstractExpert judgement is routinely required to inform critically important decisions. While expert judgement can be remarkably useful when data are absent, it can be easily influenced by contextual biases which can lead to poor judgements and subsequently poor decisions. Structured elicitation protocols aim to: (1) guard against biases and provide better (aggregated) judgements, and (2) subject expert judgements to the same level of scrutiny as is expected for empirical data. The latter ensures that if judgements are to be us...

Emotional recognition is the automatic identification of a person's emotional state by acquiring a person's physiological or non-physiological signals to achieve a more friendly and natural human-computer interaction. Similarities between the spread of infectious diseases and behavioral phenomena have been observed in large social networks. Accordingly, a framework for the spread of social p...

A proposed new approach to light rail safety management in Spain and other countries
Publication date: October 2019Source: Safety Science, Volume 118Author(s): Margarita Novales, Dominique Bertrand, Laetitia FontaineAbstractThe light rail transit (LRT) has experienced considerable growth in Spain since 1994; to date, this has led to the installation of more than 200 km of light rail lines and LRT operations in 11 metropolitan areas. Nevertheless, its institutional and regulatory framework have not been developed accordingly. Thus, in this paper, an approach for managing the LRT safety in Spain is proposed. The approach is based on the French model and could be applied to any other country that is interes...

Exploring structure, agency and performance variability in everyday safety: An ethnographic study of practices around infusion devices using distributed cognition
Discussion and conclusionSafety is constructed through the co-evolution of sociotechnical structure and agency whereby structure shapes and influences people’s behaviour and people reproduce and create structures. Everyday performance variability emerges from these interactions, including deviations in processes and outcomes (e.g. incidents, near misses and opportunities). Studies of everyday safety can explore interactions between four points of a sociotechnical structuration model: structure, agency, and satisfactory and unsatisfactory performance.

Adoption of a Bayesian Belief Network for the System Safety Assessment of Remotely Piloted Aircraft Systems
The objective of this work is to provide a systematic means of accounting for the various uncertainties inherent to any System Safety Assessment (SSA) process. The paper first defines the system safety compliance process and its modification to account for uncertainty. The SSA process, its various outputs, and associated uncertainties are defined and then applied to a generic RPAS. A Bayesian Belief Network (BBN) is adopted that facilitates a more comprehensive treatment of the uncertainty in each of the outputs of a typical SSA process. A case study of a generic RPAS is used to illustrate the features of the new approach....

We propose a new methodology to identify the path components (i.e., HE, IE, PV, AS and C) and quantify the path using data analytics approach. We have used both proactive (workplace observation (WO) and high risk control program (HRCP)) and reactive data (incident records (IR)) for this quantification. The HEs and their corresponding IEs are extracted from WO and HRCP, and then, IR is used to identify PVs, ASs and Cs. In the process, we have used ...

Publication date: October 2019Source: Safety Science, Volume 118Author(s): Wenjun Lei, Chuanmin TaiAbstractIn the process in which people enter and exit buildings, available exits in buildings are not effectively utilized and cause overcrowding at other exits. Therefore, the effect of the locations of staircases and exits on occupant evacuation was investigated in this paper. The FDS+Evac software package was used to quantify the evacuation process. Four scenarios were simulated to investigate the detailed properties of evacuation. The results revealed that the locations of staircases had a minimal effect on evacuation. Wh...

Effect of temperature on safety and stability of gas hydrate during coal mine gas storage and transportation
In this study, the hydrate dissociation experiment is conducted by using visual hydrate formation and dissociation experimental device for two kinds of CMG samples under four different temperatures. The thermal stimulation method (above the equilibrium temperature) is applied for hydrate dissociation. Based on the experimental data, it is found that the pressure curve during gas hydrate dissociation is mainly composed of three stages, including rapid dissociation, slow dissociation, and stable stages. Temperature has a significant effect on the average dissociation rate for the gas system, where a higher temperature is rel...
