The system safety concept calls for a risk management strategy based on identification, analysis of hazards and application of remedial controls using a systems-based approach.[1] This is different from traditional safety strategies which rely on control of conditions and causes of an accident based either on the epidemiological analysis or as a result of investigation of individual past accidents.[2] The concept of system safety is useful in demonstrating adequacy of technologies when difficulties are faced with probabilistic risk analysis.[3] The underlying principle is one of synergy: a whole is more than sum of its parts.
