Cycle-Based Simulation for Evaluating Temporal Exposure to In Situ Hazards

Abstract:

Quantitative evaluation of risk of operation crew performing within hazardous spaces is necessary for making safety decisions. Unfortunately, previous research is inadequate in evaluating the dynamic and fluctuating nature of operator’s exposure to hazards. Based on cycle-simulation methodology, this study proposes a two-cycle interaction simulation model. Using this model, the statistic distribution of hazardous exposure of construction crew can be explored with more statistic details. Moreover, the ratio of operation duration to cycle length is also an important factor that determines the statistic distribution of exposure time. Meanwhile, the exposure degree measured for of a low-level operation can better indicate the safety management requirement than that of a high-level activity. Consequently, better understanding of dynamic nature of exposure time may lead to improved safety management decisions.
