Validation of the impact of architectural flaws in six machine risk estimation tools
To address the hazards inherent in industrial machinery, machine designers and users must conduct risk assessments and use risk reduction measures. Machine risk estimation plays a crucial role in choosing and prioritizing risk reduction methods (e.g., level of performance required for the safety-related control system). A large number of machine risk estimation tools exist, and each tool has its own specific parameters and architecture. Flaws in a tool may bias risk estimation and lead to the adoption of inappropriate or insufficient risk reduction methods. An earlier study identified potential...
Expérimentation pratique de paramètres et d’outils d’estimation du risque
Dans une démarche d'appréciation du risque telle que définie dans la norme internationale ISO 12100:2010, l'estimation du risque est une étape essentielle permettant aux concepteurs et aux utilisateurs de machines de déterminer le niveau de risque et les situations dangereuses les plus critiques. Deux études antérieures financées par l'Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST) ont permis de révéler que les nombreux outils qui permettent de réaliser...
A visual analytics system for railway safety management
The working environment of railways is challenging and complex and often involves high-risk operations which affect both the company staff and inhabitants of the towns and cities alongside the railway lines. Rail companies adopt several strategies to reduce the exposure to risk of their employees and the public, which involve having trained personnel, safety technologies and work practices. However, despite this, railways remain high-risk operations and unfortunate incidents still occur. In this paper a visual analytics system is employed to help in the management of railway safety. This system...
Identifying the human factors associated with the defeating of interlocks on Computer Numerical Control (CNC) machines
This research sought to identify reasons why operatives defeat interlocks on Computer Numerical Control (CNC) machines, and to obtain an understanding of the extent of this behaviour across the UK engineering industry. The findings from this research provided a number of valuable insights about the frequency of defeating interlocks and the influences upon this behaviour. With regard to frequency of defeating, semi-CNC machines were identified as being commonly defeated in the sample* used in this research. Common activities associated with defeating were setting, proving, swarf removal and deburring...
A case-crossover study of work-related acute traumatic hand injuries in the People’s Republic of China
Objective: The aim of this study was to quantify potential transient risk factors for occupational acute hand injury among hospitalized workers in the People's Republic of China (PRC). Methods: Participants were recruited from 11 medical facilities in 3 cities of the PRC. A face-to-face interview was used to collect information on the occurrence of 8 potential risk factors within a 90-minute time period before an acute traumatic hand injury and during a control period within the month before the injury. The reliability of reporting transient risk factors was assessed, and a case-crossover design...
