A method for analysis and assessment of system safety based on hazardous source

摘要

Hazardous source will exist according to the characteristic or operational need of the system, and the existence of hazardous source is the fundamental reason of accident occurrence. Hazardous source needs to be identified, and the corresponding safety requirement should be proposed. Assuring the source under control will effectively decrease system safety risk to what could be accepted. Based on the root or source, analysis and assessment of system safety will be more accurate and precise. This paper introduces a method or process for analysis and assessment of system safety, and each procedure is introduced in details.
