The aim of the undertaken research was to identify the most frequently repeated accident scenarios in relation to accidents that involve scaffolding. The source of knowledge was accident documentation containing information on the circumstances of accidents, as well as their course and consequences. As part of the research, an IT Database (ITD) was developed, which involved accidents that occurred in Poland over the past five years which were related to work on scaffolding. An original graphical, mathematical and IT process model was developed in order to enable a large set of accidents involving construction scaffolding to be studied. Due to the fact that every accident proceeds according to a different scenario, a map of possible accident scenarios was developed and presented in the form of a directed graph. Graph algorithms, including the Dijkstra algorithm, were used to build the IT model.

Based on the information contained in the ITD, the course of the accident sequence was analysed in the proposed graph. The most probable accident scenarios, the probability of their occurrence, and the course of the critical path were determined. The obtained results constitute a starting point for estimating the occupational risk associated with working on scaffoldings.

进行研究的目的是确定与脚手架事故相关的最频繁重复的事故场景。知识的来源是事故记录，其中包含有关事故情况及其过程和后果的信息。作为研究的一部分，开发了一个IT数据库（ITD），该数据库涉及过去五年在波兰发生的与脚手架工作有关的事故。开发了原始的图形，数学和IT过程模型，以便能够研究涉及建筑脚手架的大量事故。由于每个事故都是根据不同的情况进行的，因此开发了可能的事故情况图，并以有向图的形式显示。图算法

根据ITD中包含的信息，在建议的图表中分析了事故序列的过程。确定了最可能的事故场景，发生的可能性以及关键路径的路线。获得的结果构成了估算与脚手架工作相关的职业风险的起点。
