6. ITAR Restricted Data 6THEMIS Mission CDR 6/18/04 Safety Policy  THEMIS Safety Policy 1. To provide a safe work place for all personnel and operations. 2. All accidents and incidents are preventable. 3. The THEMIS Program places safety before cost and schedule. If it is not safe, stop work immediately and notify your supervisor. 4. The THEMIS Program uses an organized and systematic approach to identify and control potential hazards, measure the safety risks associated with all hazards and provide risk assessment and risk mitigation plans to management.

7. ITAR Restricted Data 7THEMIS Mission CDR 6/18/04 Systems Safety Program Purpose: 1. Identifies and details the safety systems and methods that will be implemented during all phases of the THEMIS Mission. 2. Identify, evaluate and document all risks and hazards in order to eliminate or control them within the cost, schedule and technical constraints of the program. 3. Ensure that additional risks are not introduced during the design, production, integration and testing phases.

8. ITAR Restricted Data 8THEMIS Mission CDR 6/18/04 Safety is a Priority of every person Working on the THEMIS Mission. Therefore, every person working on the THEMIS Mission is part of the THEMIS MISSION SAFETY TEAM! THEMIS Mission Safety Team Mission Statement

9. ITAR Restricted Data 9THEMIS Mission CDR 6/18/04 THEMIS Safety Organization Functions The NASA Explorers Office is the Range User. As such, the Explorers Office is responsible for submitting all required safety documentation and obtaining all necessary Range Safety approvals. Under the direction of UCB, Swales is responsible for all Safety Engineer Tasks. Under the guidance of Safety Representatives from the NASA Explorers Office, Swales will produce all required safety documentation in an approved form for Range Safety submittal.

18. ITAR Restricted Data 18THEMIS Mission CDR 6/18/04 Systems Safety Program Plan Hazard Identification Processes TOP Down System Hazard Analysis During the first stages of the THEMIS design, a System Level Preliminary Hazard Analysis (PHA) was completed. This was completed in order to follow the Hazard Elimination/Mitigation Procedures Bottom Up Subsystem Hazard Analysis A Failure Modes and Effect Analysis (FMEA) is being performed which will include all possible sources of failure and their effects on both the subsystem and the system. Operations & Support Hazard Analysis Used to identify potentially hazardous operations and critical GSE. Conducted using the final design, I&T Plan and Launch Site Ground Operations Plan. Output is the correct classifications of hazardous and non-hazardous operations for the Work Order Authorization process.

19. ITAR Restricted Data 19THEMIS Mission CDR 6/18/04 Systems Safety Program Plan Hazard Analysis The inputs to the Hazard Analysis are the PHA (system level), FMECA (subsystem level with respect to the system) and the Operations and Support Hazard Analysis.
