Overview

Safety analysis comprises hazard analysis, safety risk assessment and supporting analyses as defined in ECSS-Q-ST-40. The objective of safety analysis is to identify, assess, reduce, accept, and control safety hazards and the associated safety risks in a systematic, proactive, complete and cost effective manner, taking into account the project's technical and programmatic constraints. Safety analysis can be implemented through an iterative process, with iterations being determined by the project progress through the different project phases, and by changes to a given project baseline. Hazard analysis comprises the identification, classification and reduction of hazards. Hazard analysis can be implemented at each level of the customer-supplier network. Hazard analysis activities at lower level can contribute to system level safety analysis. System level safety analysis can determine lower level hazard analysis activities. Hazard analysis interfaces with dependability analysis, in particular FMECA. Safety risk assessment interfaces with quantitative dependability analysis, in particular reliability analysis. Safety risk assessment contributes to project risk management. Ranking of safety risks according to their criticality for project success, allowing management to direct its attention to the essential safety issues, is part of the major objectives of risk management. Safety risk assessment is further addressed in ECSS-Q-ST-40. This Standard details the hazard analysis requirements of ECSS-Q-ST-40; it defines the principles, process, implementation, and requirements of hazard analysis. It is applicable to all European space projects where during any project phase there exists the potential for hazards to personnel or the general public, space flight systems, ground support equipment, facilities, public or private property or the environment. This standard may be tailored for the specific characteristics and constrains of a space project in conformance with ECSS-S-ST-00. This document (EN 16602-40-02:2014) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN (Germany). This document replaces DIN EN 14738:2004-08. This document has been developed to specifically cover space systems and therefore has precedence over any European Standard since it covers the same scope but with a wider domain of applicability (for example aerospace). The responsible German body is Working Committee NA 131-10-01 AA "Interoperabilität von Informations-, Kommunikations- und Navigationssystemen" ("Interoperability of information, communication and navigation systems") of the DIN Standards Committee Aerospace (NL).
