1.2.4.1 System Safety

• Implement a tailored system safety and mission success activity based on the loss potential of the program and provide adequate resources to achieve the safety objectives.
• Assign a System Safety Manager (SSM) in coordination with the Center Safety and Mission Assurance (SMA) Director, to have specific responsibility for executing the system safety tasks within the project.
• Implement and maintain the system safety and mission success planning portion of the risk management activity of the program plan with guidance and assistance from the local SMA organization. A separate stand-alone safety plan may be requested.
• Perform system safety and mission success reviews of the program.
• Establish a formal, closed loop, risk acceptance process to identify and track program hazards with residual risk.
• Issue program directives, specifications, and standards that provide uniform and systematic application of safety policy and requirements.
• Assign sufficient numbers of personnel of appropriate experience and skills to perform system safety tasks. Provide training when necessary.

Additional Program Manager's system safety responsibilities regarding the System Safety Plan (SSP) are listed in Appendix I of NPG 8715.3, NASA Safety Manual w/Change 2.

"The principal objective of a system safety activity is to provide for an organized, disciplined approach to the early identification and resolution of hazards impacting personnel, hardware, or mission success to a level as low as reasonably achievable (ALARA)." (NPG 8715.3, NASA Safety Manual w/Change 2, Section 3.3)

• Defines the objectives, responsibilities, and methods to be used for overall safety program conduct and control."
• Is the vehicle for safety task planning? The SSP will include detailed task requirements for the system safety task as tailored from (NPG 8715.3) for the program.
• Will stipulate hazard analysis methodologies, hazard report (HR) data and format requirements, and the approval reporting channels for HRs and their milestones.
• Will address requirements for NASA and contractor participation in design, safety, and readiness reviews.
