Taking Safe Decisions - Worked Examples
All of the worked examples are structured according to the Taking Safe Decisions risk management framework, shown below.
- The removal of fire extinguishers describes the removal of a risk control that is no longer providing an overall safety benefit. It illustrates a relatively simple decision made largely on the basis of qualitative analysis and expert judgement
- The provision of signal post telephones when adopting GSM-R illustrates the complexities of decisions involving multiple organisations. It discusses the psychology of decision making, in particular the importance of framing the decision in the right way.
- Formation of an infrastructure manager / railway undertaking alliance shows how structured workshops can be used to evaluate risk and identify safety measures when making an organisational change.
- Final drive failures illustrates how risk assessment and safety monitoring can combine to support the iterative design and implementation of safety measures. It also provides an example of a company deciding to go beyond its legal safety requirements to reduce its reputational risk.
RSSB is committed to the delivery of further worked examples and supporting material over time.
