Safety Risk Management – 673.25
By adopting this ASP, PBT is establishing the SRM process presented in Figure 3 for identifying hazards and analyzing, assessing and mitigating safety risk in compliance with the requirements of 49 CFR Part 673.25. The SRM processes described in this section are designed to implement the PBT SMS.

Safety Risk Mitigation
The implementation of the SRM component of the SMS will be carried out over the course of the next year. The SRM components will be implemented through a program of improvement during which the SRM processes will be implemented, reviewed, evaluated, and revised as necessary, to ensure the processes are achieving the intended safety objectives as the processes are fully incorporated into PBT's SOPs.
The SRM is focused on implementing and improving actionable strategies that PBT has undertaken to identify, assess and mitigate risk. The creation of a Risk Register provides an accessible resource for documenting the SRM process, tracking the identified risks, and documenting the effectiveness of mitigation strategies in meeting defined safety objectives and performance measures. The draft Risk Register is presented in Figure 4.

Consequences (What could happen?)
Resolution (What could mitigate this?)
As the SRM process progresses through the steps of identifying what may be wrong, what could happen as a result, and what steps PBT is taking to resolve the risk and mitigate the hazard, the CSO completes and publishes the various components of the Risk Register. These components include the use of safety hazard identification, safety risk assessment, and safety risk mitigation, as described in the following sections.
