“…It should be noted that CA uses inertia to measure the strength of correlation between row and column variables, and the dimensionality reduction process may cause some information loss. Higher inertia means less information is lost, and the ratio of the information carried by the two dimensions to total information is represented by the inertia ratio 33. In this case, the inertia ratio of the two dimensions shown in the figure accumulates to 1.000, indicating that no data is lost during the dimensionality reduction process of this analysis, which verifies that the correlations obtained in this analysis are reliable.Correlation between variables is shown in a two-dimensional scatter plot by the position between two corresponding points: the smaller the distance between the two points, the stronger the correlation; the smaller and sharper the angle between the two lines, the stronger the correlation between the two points when they are connected to the origin as rays.…”

Accidents in process industry occur frequently with serious casualties and property losses. This paper builds an accident causation model of process industry based on system thinking by dividing the accident causation system into 4 subsystems and 22 factors. A combination of grey relational analysis and correspondence analysis is conducted to carry out a structured analysis of the collected data. The research contains three main parts: (1) Grey relational analysis is used to obtain the significance ranking of 22 cause factors in process industry, and three critical cause factors are identified as “Security inspection,” “Risk identification,” and “Security awareness.” (2) Through correspondence analysis, the correlations between three sets of variables are analyzed and the cause factors requiring focused attention are identified as “Electric spark,” “Temperature,” “Raw material control,” “Punching phenomenon,” “Equipment clogging,” and “Combustible gases.” (3) An intelligent monitoring scheme is developed for the critical factors of each subsystem, which aims to achieve real‐time monitoring and early warning by means of video surveillance and sensor placement for the human, equipment, and environment subsystems. The conclusions obtained from this study can be used to enhance the efficiency of safety management and reduce the probability of accident occurrence in the process industry.

“…Furthermore, some studies have used qualitative methods such as the cause–effect diagram and Ishikawa (fishbone) diagram to determine the root cause behind the accident. For example, Fishbone Diagrams and Root Cause Analysis were applied to the in‐depth analysis of physical security‐ and cybersecurity‐related events that affected the process industry 14 . A quantitative risk evaluation method that combined a risk matrix, fault tree, and fishbone diagram model is proposed in Reference 15 to define the risk level of a spherical tank.…”

A total of 42,032 workplace accidents were reported in 2021 by the Algerian National Social Insurance Fund for Salaried Workers in Algeria, of which 38,225 were accidents within the workplace and 3807 were related to traffic accidents or other reasons. Most of these accidents were recorded in the building and construction field, followed by the oil and gas company exploration and drilling, which comes at the forefront of the Sonatrach company. This study aims to analyze accidents in the workplace using quantitative and qualitative methods to determine the corresponding causes. Our study was carried out in collaboration with Sonatrach in south Algeria where information and reports on work accidents from years 2017 to 2021 were collected. Data acquired were classified and analyzed according to the location and time of the accident. Based on the results obtained, we found that the human factor was the main cause of most accidents due to nonrespect of safety procedures and lack of concentration of workers. The results of the analysis suggest implementation of a break time during the afternoon, avoiding long overtime hours, suspending work outside stations during high temperatures periods in July and August as well as suspending work when sandstorms appear in winter.

The Algerian National Social Insurance Fund for Salaried Workers in Algeria reported over 42,000 accidents in 2021. 1 The Algerian law of July 1983 provides in Article 6: "it is considered as an accident at work any accident having caused a bodily injury, attributable to a sudden, external cause and occurring within the framework of the employment relationship". 2 Worldwide, workplace accidents are witnessing frightening statistics, according to the International Labor Organization. Every 15 s, a worker dies from a work-related accident or illness. Also, every 15 s 153 workers suffer a work-related accident and 321,000 people die each year from work-related accidents. 3Despite all efforts to reduce these incidents, they still occur, especially in some industrial countries. In the past three decades, major industrial accidents have occurred, causing deaths and injuries to workers. Among these incidents:• The Ocean Ranger tragedy in Newfoundland and Labrador, Canada occurred on 15 February 1982 and caused the death of 84 workers.The rig in Ocean Ranger was designed and built by Onshore Drilling and Exploration Company (ODECO) in 1976. 4• Sayano-Shushenskaya power station accident in Yenisei River, near Sayanogorsk in Khakassia, Russia. Occurred on 17 August 2009 at 08:13, 75 people were killed and billions of roubles were lost. 5

“…Liquefied petroleum gas (LPG) and natural gas liquids (NGLs) contain significant proportions of light hydrocarbons (C3-C6) [7]. One of the tasks solved by numerical modelling is the search for probable air stagnation zones (areas where the air flow (wind) speed does not exceed 0.5 m/s) in the territory of hazardous industrial facilities (HIF) [8][9]. Options for solving this problem were considered by scientists R.R.…”

The risk of accidents involving light hydrocarbons is caused by the physicochemical properties of the components, primarily propane and butane. The most catastrophic accidents involving these substances were on November 19, 1984, in the city of San Juan Ixhuatepec (Mexico) and on June 4, 1989, on the Asha – Ulu-Telyak section (USSR), in each of which more than 500 people died. The novelty of the study is determined by the requirement to ensure industrial and fire safety of storage facilities for light hydrocarbons by predicting probable zones of air flow stagnation. The authors calculated the formation of probable air stagnation zones for various space-planning solutions by using a three-dimensional modelling system and the finite volume method. The paper developed a methodology for assessing the safety of storage facilities for light hydrocarbons in emergency situations, which is based on the analysis of probable air stagnation zones by using three-dimensional modelling systems. The practical significance of the study is determined by the additional development of a parameter for assessing the safety state of a storage facility for light hydrocarbons (Ks) and a resulting parameter (Kr) for calculating the optimal location of structures and their structural changes. Integration of stagnation zone sizes into a single formula with the results of other safety calculations is an urgent scientific and applied problem.
