Human factors engineering
The human factor – cost-effective safety critical task analysis
Human failures have contributed to many major accidents in high hazard sectors, such as Chernobyl, Ladbroke Grove and Deepwater Horizon. However, the analysis of safety critical tasks has lagged behind efforts to analyse hardware failures, mainly driven by the perception that assessing the enormous number of tasks at an industrial facility would be too time consuming. Today, practical methods have been developed to help the cost-effective analysis of safety critical tasks.
Fatigue risk management with bowties
Fatigue is a major issue for organisations with shift working patterns, especially those with long or irregular hours. Where facilities operate 24/7, extended wakefulness, inadequate sleep and night work can be common and it is impossible to totally eliminate fatigue from the workplace.
An introduction to behavioural safety
Have you ever wondered why people do what they do? Is there a way to influence the way people behave so that the job gets completed in the most efficient, productive and safe manner? In the discipline of behavioural safety, the most effective way to achieve this is to understand the underlying reasons for people's outwardly expressed behaviour and to give them an informed choice in the workplace.
Chronic unease – the hidden ingredient in successful safety leadership?
Leaders working in high hazard industries are faced with a difficult personal challenge: how do you avoid complacency about major accidents such as a nuclear release, oil spill or train derailment, when such events rarely happen? How do you not 'forget to be afraid'?
The integral safety leader – thinking about the whole
Put yourself in the mind of a line manager responsible for the safety of personnel. You have been warned of many deficiencies in a part of the business, including a strong indication that a significant accident has a worryingly high potential. How do you begin to think about this problem?
Breaking down the barriers to human factors integration
Human factors (HF) has become relatively well-known as a scientific and engineering discipline that can be used to improve the safety and efficiency of systems, reducing risk and cost [Ref 1]. The list of HF tools available for use by both specialists and lay practitioners is as extensive as the discipline is broad. But how does a project or organisation know which tools to use and when? How do we ensure HF is applied in a cost-effective manner? How much HF is enough and when does it stop adding value?
