Review of Systematic Safety Analysis Technique Research

The systematic safety analysis technique includes the preliminary, the subsystem, the system, operational & support and occupational health hazard analysis, each kind of analysis is suitable for the cyclical different stage, and divides into the qualitative and the quantitative analysis. The qualitative analysis uses in inspecting, the analysis accident, the determination possibly exists accident and its influence protective measure. The quantitative analysis take the qualitative analysis as the basis, uses in probability which inspects, the analysis and the determination concrete danger, the accident and its occurs, after systematically uses the safety measure or the change of design proposal compares the probability change.
