turvallisuusanalyysimenetelmä

Turvallisuusanalyysimenetelmä, often translated as safety analysis method, is a systematic process used to identify potential hazards and risks associated with a system, product, or activity and to evaluate the likelihood and severity of their consequences. The primary goal of these methods is to prevent accidents, protect people, property, and the environment.

These methods can be applied at various stages of a project lifecycle, from initial design and development to operation and maintenance. They help in understanding the inherent safety of a system and in determining necessary safeguards. Different methods exist, each suited for specific applications and levels of detail. Common techniques include Hazard and Operability Study (HAZOP), Failure Mode and Effects Analysis (FMEA), Fault Tree Analysis (FTA), and What-If analysis.

The selection of a particular turvallisuusanalyysimenetelmä depends on factors such as the complexity of the system, the criticality of its function, regulatory requirements, and available resources. The output of a safety analysis typically includes a list of identified hazards, their potential causes, the associated risks, and recommended mitigation measures. These recommendations are then implemented to reduce the risks to an acceptable level. Continuous review and updating of safety analyses are crucial to account for changes in the system or its operating environment.
