3 3 Purpose of the Standard Casualties on the ground Launching Country Commercial Company (manufacturers, operators, and customers) Risk Management to Prevent Causalities ISO Standards System Safety Risk Management Assessment of Risk Risk Reduction Management Plan Safety If not, by Voluntary Activities

4 4 Safety Program Re-entry risk management Organization to perform safety functions Safety programme plan Review System Safety activities

5 5 Assessment flow Estimation of Risk Assessment of risk caused by re-entering debris Casualty limit Approved Analysis tool and data for survivability determination Imposed by Government or self-restriction Probabity of Risk Realization Risk Senarion and Consequence of Effects

6 6 Complete Demise < threshold > threshold Effect on the Earth Environment : Threshold Controlled Re-entry Survive START: Survivability Analysis Risk on Human : Threshold completely demised or survived? Design Change Is the risk reduction possible by design change? possible Impossible Disposal by Natural Decay or Reduction of Orbital Lifetime (uncontrolled re-entry) Risk Assessment Flow and Disposal Planning

7 7 Risk reduction measures Controlled re-entry Structural design to reduce survivability Notification Option for Risk Reduction
