Correlation analysis and prevention of electrocution risk factors in the construction industry

Li Jue, Chen Feifei, Li Shije

Archives of Civil Engineering

2022

Vol. 68, nr 4

537--554

Electrocution is one of the main causes of workplace deaths in the construction industry. This paper presents a framework for identifying electrocution risk factors and exploring the correlations between them, with the aim of assisting accident prevention research. Specifically, the Haddon Matrix is used to extract the risk factors from 193 investigation reports of electrical shock accidents from 2012-2019, and the Apriori algorithm is applied to examine the potential relationships between these factors. Based on association rules using three criteria: support (S), confidence (C) and lift (L), the betweenness centrality is then introduced to optimize association rules and find the most important rules though comparison. The results show that after optimization, some of these critical rules rise significantly in rank, such as Workplace: indoor → No CPR provided. Through these ranking changes, the focus of safety management is clarified, and finally, based on a comprehensive analysis of association rules, targeted accident prevention measures are suggested.

Na terenie trzech stacji paliw wykonano oznaczenia stężenia węglowodorów w powietrzu przy dystrybutorach, zbiornikach paliw oraz tankowanych samochodach. Poddano także analizie wody gruntowe pobrane na terenie stacji Nr 1 i ścieki deszczowe odprowadzane z tego obiektu. Ponadto w oparciu o materiały Głównego Inspektora Ochrony Środowiska (GIOŚ) z lat 2006-2012, podjęto próbę oceny zagrożenia stacji dystrybucji paliw i LPG w Polsce poważnymi awariami oraz zdarzeniami o ich znamionach.

Hydrocarbons concentrations were determined in air near fuel pumps, fuel tanks and fed vehicles in three fuel stations. Moreover, groundwater sampled in the fuel station no. 1 as well as fall wastewater drained from this object were analyzed. Taking into consideration data from the Chief Inspector of Environmental Protection related to the period of 2006-2012, a trial estimation of fuel and LPG stations hazard by major accidents and similar events in Poland, was made.
