In summary, the results of this study suggest that measuring safety culture provides a useful method to monitor changes in company safety performance and may assist in identifying elements of a safety management program that require improvement (e.g. a hazard reporting system). Measuring individuals subjective estimation of risk may also provide management with feedback regarding employees appraisal of the safety of their operation. However, there may be a point where a lower perception of risk could be potentially unhealthy for an organisation. Future research may need to more clearly identify this problem.
