3.1.24
safe state
state that does not lead to critical or catastrophic consequences
3.1.25
safety critical function
function that, if lost or degraded, or as a result of incorrect or inadvertent operation, would result in catastrophic or critical consequences
NOTE Adapted from EN 13701:2001.
3.1.26
safing
action of containment or control of emergency and warning situations or placing a system (or part thereof) in a predetermined safe condition

3.1.28
system
set of interdependent elements constituted to achieve a given objective by performing a specified function
NOTE The system is considered to be separated from the environment and other external systems by an imaginary surface which cuts the links between them and the considered system. Through these links, the system is affected by the environment, is acted upon by the external systems, or acts itself on the environment or the external systems.
[IEC 60050:1992]
3.1.29
system safety
application of engineering and management principles, criteria, and techniques to optimize all aspects of safety within the constraints of operational effectiveness, time, and cost throughout all phases of the system life cycle
3.1.30
warning condition
condition where potentially catastrophic or critical hazardous events are imminent and where pre-planned safing action is required within a limited time
NOTE Adapted from EN 13701:2001.
3.1.31
zonal analysis
systematic inspection of the geographical locations of the components and interactions of a system, evaluation of potential subsystem-to-subsystem interactions with and without failure, and assessment of the severity of potential hazards inherent in the system installation.
d) Tailoring shall not diminish the intent to protect flight and ground personnel, the launch vehicle, associated payloads, ground support equipment, the general public, public and private property, and the environment from hazards associated with space systems.
4.2 Safety organization
4.2.1 General
Each supplier is responsible for the safety of his product as detailed in next subclauses.
4.2.2 Safety representative
Each supplier shall appoint a safety representative in accordance with ISO 14300-2 who is qualified by training or
experience to perform system safety functions.
4.2.3 Reporting lines
Safety representatives shall have reporting lines to the project manager and access to top management that are independent of the hierarchical reporting line within the project.
4.2.4 Safety integration
Safety shall be integrated in all project activities.
4.2.5 Coordination with others
The safety representatives should coordinate with all affected medical boards, radiation protection committees, industrial safety organizations and environmental protection agencies as appropriate.
4.3 Safety representative access and authority
4.3.1 Access
The safety representative of an organization shall have access to that organization’s safety related data relevant to project safety, and shall be at liberty to report freely, and without organizational constraint on any aspect of project safety.
4.3.2 Delegated authority to reject – stop work
The safety representative of an organization shall have the delegated authority to reject any project document, or to stop any project activity of this organization that does not conform to approved safety requirements or procedures.
4.3.3 Delegated authority to interrupt operations
To properly control risk, the safety representative of an organization shall have the delegated authority to interrupt hazardous operations of this organization and make the system under consideration safe again when it becomes clear that the operation does not conform to the agreed measures.
4.3.4 Conformance
The supplier shall assure conformance of his own and his subsuppliers’ project activities with project safety policy and requirements.
4.3.5 Approval of reports
The supplier should not permit project reports that address matters related to safety certification to be issuedwithout signed approval of the safety representative.
4.3.6 Review
No project hazardous operation or system mission shall be permitted to proceed without prior review and approvalby the safety representative.
