Overview

During the assessment phase, it maybe necessary to assess a number of different technical options and to select the solution which best meets the SRD and therefore the URD. From a safety prospective, it is necessary to consider the compliance with the Safety Requirements of each option and the safety hazards presented by each option, as it is conceivable that the best technical option is intolerably unsafe and should not be progressed.

Task

Task A – Hazard Identification

You will need to review the three technical options and undertake hazard analysis of each option:

  • Use the general checklist from ASEMS SMP04 to help identify hazards [Hint: you may want to refer back to the preliminary hazard identification output]

When identifying hazards, you may wish to consider:

  • Safety related interfaces between the various elements of the system
  • New hazards introduced by the different options
  • Human error
  • Maintenance and emergency procedures
  • Defence against common mode failures

Conclusion

Now that you have completed the hazard analysis of the three technical options, update the Padlet below to capture:

  • Your findings from the hazard analysis of each option
  • Which is your preferred option, based upon the outcome from the hazard analysis, and justify your selection
