Gestão da Prevenção nos Comboios de Portugal: Influência do Controlo de Risco do Comportamento Humano na Sinistralidade Profissional

Durante cinco anos, foi intervencionada e estudada, a sinistralidade laboral numa transportadora ferroviária. O controlo de riscos nela experimentado explorou o potencial preventivo de medidas de controlo do comportamento dos colaboradores, tais como: Formação para promover comportamentos preventivos; Intensificação da prevenção, controlo e recuperação do abuso de álcool e drogas; Informação motivadora para as boas práticas. Consequentemente: Inverteu-se rapidamente a tendência crescente da sinistralidade, sem aumentar custos; Mantiveram-se, durante um período de continuada redução do efectivo laboral, níveis de sinistralidade laboral inferiores aos verificados no início da pesquisa; Demonstrou-se a sustentabilidade financeira do investimento em Segurança e Saúde do Trabalho. During five years, an intervention, over the occupational accidents of a railway company, was studied. The control of risks that has been tested, explored the preventive potential of control measures towards employees’ behaviour, such as: Training to promote preventive behaviours; Stepping up prevention, control and recovery of alcohol and drugs abuse; Motivating information to good practices. Consequently: It quickly reversed the trend of accidents, without increasing the costs; During a period of continued reduction of employees, levels of occupational accidents remained below those recorded at the beginning of research; Financial sustainability of investment in Occupational Health and Safety was demonstrated.

Aplicação de Data Mining à Segurança do Trabalho Ferroviário

Embora o objectivo de redução de acidentes laborais seja frequentemente invocado para justificar uma aplicação preventiva de testes de álcool e drogas no trabalho, há poucas evidências estatisticamente relevantes das pressupostas causalidade e correlação negativa entre a sujeição aos testes e os posteriores acidentes. Os dados de testes e dos acidentes ocorridos com os colaboradores de uma transportadora ferroviária portuguesa de âmbito nacional, durante anos recentes, começam agora a ser explorados, em busca de relações entre estas e outras variáveis biográficas. - Although the aim of reducing occupational accidents is frequently cited to justify preventive drug and alcohol testing at work, there is little statistically significant evidence of the assumed causality and negative correlation between exposure to testing and subsequent accidents. Data mining of tests and accidents involving employees of a Portuguese national wide railway transportation company, during recent years, is now beginning in search of relations between these and other biographical variables.

Understanding safety and production risks in rail engineering planning and protection

Much of the published human factors work on risk is to do with safety and within this is concerned with prediction and analysis of human error and with human reliability assessment. Less has been published on human factors contributions to understanding and managing project, business, engineering and other forms of risk and still less jointly assessing risk to do with broad issues of ‘safety’ and broad issues of ‘production’ or ‘performance’. This paper contains a general commentary on human factors and assessment of risk of various kinds, in the context of the aims of ergonomics and concerns about being too risk averse. The paper then describes a specific project, in rail engineering, where the notion of a human factors case has been employed to analyse engineering functions and related human factors issues. A human factors issues register for potential system disturbances has been developed, prior to a human factors risk assessment, which jointly covers safety and production (engineering delivery) concerns. The paper concludes with a commentary on the potential relevance of a resilience engineering perspective to understanding rail engineering systems risk. Design, planning and management of complex systems will increasingly have to address the issue of making trade-offs between safety and production, and ergonomics should be central to this. The paper addresses the relevant issues and does so in an under-published domain – rail systems engineering work.
