Is the measurement of ‘safety culture’ a valid management tool in the effort to reduce accident rate and improve safety performance, or is it a fuzzy academic concept, lacking empirical validation? The answer to this question seems to depend on whom one asks. The UK Health and Safety Commission has encouraged companies to improve their safety performance through the development of a ‘positive safety culture’. However, academic discussions in this area suggest that the concept remains vague, lacks empirical validation and is used as an ‘umbrella term’ for all the social and organizational factors that affect accident rate. This paper reviews the existing literature on safety culture and provides some clarification in terms of definition, empirical evidence and theoretical development. A theoretical framework of the mechanisms by which safety culture affects safety behaviours in organizations is proposed. The implications for practical management issues are discussed and future challenges and areas for further research are identified.
