Large-Scale Escalator Risk Assessment Technology Coupling Model

Abstract

Safety assessment is an effective means to improve the safety of escalators. In recent years, there are more than 4,000 escalators that need to be evaluated in Beijing to ensure the city's public management level. This paper introduces the Functional Hazard Analysis (FaHA), which illustrates the application of large-scale risk assessment of urban scale in Beijing, the safety assessment process and assessment project improvement based on functional hazard analysis in escalator risk assessment, and traditional risk assessment. Highly dependent on the quality of personnel, it is difficult to ensure quality comparison when the quantity is huge. This method has the advantages of fairness and efficiency, and is especially suitable for large-scale evaluation.
