Abstract: | Introducing safety devices does not always reduce the frequency of accidents. Operators adjust their response to technological improvements. Protection mechanisms may be used to support “unsafe” working practices so that the net risk of failure remains unchanged or may even rise. Regulatory bodies have reacted against this risk compensation. Rules and procedures have been imposed upon the day-to-day operation of protection equipment. Unfortunately, these constraints often fail to preserve the safety of an application. Inattention, fatigue, poor training and willful neglect can lead to rules and guidelines being ignored. In this paper alternative means of reducing threats posed by risk compensation are explored. In particular, it is argued that designers must exploit an integrated approach to the development of high-risk applications. By this we mean that both human factors and systems engineering must be recruited to support the development of protection equipment. |
