Abstract

In order to improve the safety of the production process, in-depth research on accidents with human error as the main and machine failure as the second was carried out. Based on Lawrence accident model (L), behavioral safety "2-4" model (B), trace intersection theory, and accident cumulative effect theory, combined with safety ergonomics and other related knowledge, " L-B" man-machine accident model was constructed, and the actual case was analyzed. The results show that the accident model includes seven stages: work stage, hidden danger stage, trigger stage, occurrence stage, emergency stage, calm stage and recovery stage, analyzes the causes of accidents from various angles and illustrates the development characteristics of accidents from the beginning of production activities to the occurrence of accidents later, which can provide a reference for enterprises to formulate safety measures. © 2022 China Safety Science Journal.
