The Relationship between the Economic Consequences of Accidents and Safety Measures: A Case Study

Background: Accidents impose harmful economic consequences for workers, employers, and society. The present study aimed to evaluate the economic consequences of occupational accidents. Methods: This descriptive-analytical study was conducted in the Iranian Gas Engineering and Development Company in 2020. Data collection tools were a checklist and a researcher-made questionnaire. The reliability of this questionnaire was calculated through Cronbach's alpha coefficient. Data analysis was conducted using SPSS statistical software and the significance level was considered 0.05. Results: The reliability of this questionnaire was estimated at α = 0.87. The average lost work day caused by occupational accidents was 36.67 days and the average cost imposed for each accident was 23.97 million Tomans. The total safety index in the studied environment was calculated at 3.59± 1.01. The results of linear multivariate regression analysis indicated that the cost imposed for each accident has a significant relationship with accident type and accident consequence, level of education, number of workers, training hours, work experience, salary, and total safety index (p <0.05). Conclusion: The findings of this study showed that the economic performance of a company can be affected by individual, occupational, and most importantly safety factors of the company. In addition, such factors are considered as strong predictors for economic safety performance.

Statistics of Dangerous Cargo Accidents during Highway Transportation

Research on present situation and trends of accidents takes an important role on prevention and control on dangerous cargo accidents during highway transportation. According to the current situation of highway transportation for dangerous cargo, the characteristics of highway transportation system for dangerous cargo are put forward. Statistical analysis of dangerous cargo in China from 2013 to 2019 related to characteristics and consequences are discussed in this study. The different time volatility, spatial distribution and accident consequence features are revealed. Results show that the dangerous cargo of highway transportation system presents a multiple spots, long lines, broad coverage, and high risk features. The annual scale of dangerous cargo accidents shows irregular ‘M’ distribution since 2013. December is the month with the most accidents. Wednesday is the day with the most accidents. Fifth period is the most accidents. Shandong is the province with the most accidents. Normal section is the section with the most accidents. The liquid is the type with the most accidents. Leakage is the most common type of accident. Countermeasures focusing on improving highway transportation safety for dangerous cargo accidents are recommended.

Review on fire explosion research of crude oil storage tank

With the rapid development of the world economy, the petrochemical industry energy reserve strategy and production demand increase, petrochemical storage tank farm scale is also expanding, and continue to large, intensive direction of development. In recent years, there are many disastrous accidents such as oil leakage, explosion and combustion of storage tank, so it is necessary to study the combustion and explosion behavior of storage tank. This paper studies the mechanism of explosion combustion in crude oil tank area, summarizes and states the progress of crude oil explosion combustion research at home and abroad, and lists several common risk evaluation methods for tank risk management, which can provide technical support for safety management and accident emergency rescue through qualitative, quantitative evaluation and accident consequence simulation calculation. Therefore, we should sum up the experience and lessons from the accident, strengthen the theoretical research, to avoid the recurrence of similar accidents, and effectively guarantee the safety of national energy reserves.
