Strategies for Inherent Safety Design during Engineering Construction

Based on the study of layers of defense against a possible accident, the central position of inherent safety design was established. The opportunity for the inherent safety during engineering construction was analyzed. It is easier to realize the inherent safety with low cost during the early stage of design. The inherent safety design of engineering construction was divided into four stages, namely feasibility study, construction technological design, construction design and basic design, then their design strategies were discussed. Meanwhile, the process for inherent safety design during engineering construction was presented. The inherent safety level can be improved by many measures, such as site investigation research, the simplification and optimization of construction process, the balance of economy and construction safety, safer construction equipment design, etc.
