The Safety Analysis and Risk Mitigation Process  Section 3  56 3.7_SMSM_201607  Originally published July 2016  Uncontrolled copy when downloaded All safety requirements identified by the Safety Risk Management (SRM) panel and included in  the Hazard Analysis Worksheet (HAW) are considered to be recommendations for review and  approval by the appropriate signatories. After appropriate means of managing risk have been  developed and documented by the SRM panel, management officials may identify the effect of  safety requirements on other organizations and coordinate with the affected organizations. It may be necessary to perform separate safety analyses on the safety requirements to  determine their effects on the NAS. If so, the associated safety analyses must be developed,  completed, and approved for implementation before proceeding with implementation of the  original NAS change.  Refer to  Section 6.3 for more information on safety requirements approval and implementation  decision-making and signatures. Predicted residual risk  is the risk that is estimated to exist after the safety requirements are  implemented or after all avenues of risk reduction have been explored. The predicted residual  risk is based on the assumption that controls are in place and/or all safety requirements are  implemented and are valid. If safety requirements are not documented in the HAW, predicted  residual risk should be the same as the initial risk.  If the risk cannot be reduced to an acceptable level after attempting all possible risk reduction  strategies, either revise the original objectives or abandon the proposed NAS change. If an  acceptable proposal is not identified, the NAS change cannot be implemented. Similarly, if a  NAS change was implemented without safety requirements and the predicted residual risk was  not met, the safety analysis must be revisited, which may require the development of safety  requirements. Refer to Section 4.3.2 for more information.  3.7.4  Determining Predicted Residual Risk  3.7.3  Documenting Safety Requirements
