10. Preparation Instructions

The Safety System Program Plan shall include the following:

10.1 General:
     a. Description of the scope of the overall program and the related system safety assurance program.
     b. Description of the tasks and activities of system safety assurance management and engineering
        and the interrelationship between system safety assurance and other functional elements of the
        program. A cross-reference of system safety assurance program requirements and tasks included
        in other contractual documents may be provided to avoid duplication of effort.
     c. The contractor and government documents, which will be applied either as directives or guidance
        in the conduct of the system safety program.
     d. An item-by-item accounting of all contractually required system safety assurance tasks and
        responsibilities.

10.2 Safety requirements
     a. Safety Assurance Organization:
         The system safety assurance organization or function within the organization of the total
             program using charts to show the organizational and functional relationships, and lines of
             communication.
         The responsibility, authority, and accountability of system safety assurance personnel, other
             contractor organizational elements involved in the system safety effort, and subcontractor
             system safety assurance organizations, if applicable.
         The staffing of the system safety organization for the duration of the contract to include the
             qualifications of assigned personnel.
         A description of the procedures which will be used to integrate and coordinate the system
             safety assurance tasks including dissemination of the system safety assurance requirements
             to action organizations and subcontractors, of subcontractor’s system safety assurance
             programs, integration of hazard analyses, program and design reviews, and program status
             reporting.

Preparation Instructions Continued

              The process through which management decisions will be made to include notification of
               critical and catastrophic hazards, corrective action taken, mishaps or malfunctions, waivers to
               safety requirements, and program deviations.

       b. System safety assurance program schedule:
           The schedule when safety milestones will be achieved in relationship to other program
              milestones.
           Integrated system safety assurance activities including design analyses, tests, and
              demonstrations applicable to the system safety program. Include manpower loading required
              for these activities.

       c. System safety assurance requirements:
           A description of the methods that will be used to identify and apply safety/hazard control
              requirements and criteria for design of equipment, software and facilities, and for procedures,
              for all phases of acquisition specified by the contract SOW. A list of the sources of safety
              requirements (e.g. standards and system specifications) that are required for compliance and
              any approaches intended to be used.

              The hazard assessment procedures. State any qualitative and quantitative measures of
               system safety assurance that are to be used, including a matrix and description of the hazard
               levels and associated criticalities including the effects of Hazardous Misleading Information
               (HMI) and Loss of Function (LOF). Describe the process to be used to determine hazard
               causes and effects, and recommended corrective action.
               o Describe the depth within the system to which each system safety assurance analysis
                    technique will be used including hazard identification associated with the system,
                    subsystem, components and software.
               o Describe the process for integration of subcontractor hazard analyses and techniques
                    within overall system hazard analyses.
              The technique for establishing a single closed-loop hazard tracking system, for reporting and
               for tracking incidents that could impair safety.
              The management controls that shall be used to ensure compliance or justify waivers/deviations
               with general design and operational safety criteria, and the closed-loop procedures to ensure
               hazard resolution.

       d. System safety data. The plan shall include a description of the approach for identifying, obtaining,
          researching, disseminating, and analyzing pertinent historical hazard or mishap data.

       e. Safety verification:
           The verification requirements for ensuring that safety is adequately demonstrated.
           The procedures for ensuring feedback of test information for review and analysis.
           The procedures for ensuring that all detected hazards have been eliminated or controlled to an
              acceptable level of risk.
