ABSTRACT

Based on the literature research and the actual situation of investigation in Jinwan district of Zhuhai city, the risk factors of production safety accidents in Jinwan district of Zhuhai city were constructed, and the risk factors of production safety accidents are divided into 6 secondary indicators and 20 tertiary indicators. According to the risk matrix formula, the risk levels of production safety accidents in Jinwan district of Zhuhai city are evaluated from the two aspects of occurrence probability and consequence severity, and further ranked by the Borda count method. The results show that road traffic accidents, construction accidents, fire accidents, network and information security incidents, maritime traffic accidents and heavy pollution weather are intolerable risks. Finally, this paper puts forward the risk governance strategy from the aspects of advancing the construction of rule of law, strengthening responsibility, enhancing the investigation and rectification of the risk, improving emergency rescue capabilities and consummating the support safeguard system.

1. Introduction

With the opening of the Hong Kong-Zhuhai-Macao Bridge, the Guangdong-Hong Kong-Marco Greater Bay Area will become the new economic growth pole of Zhuhai, which will promote the further development of Zhuhai’s economy. As one of the important administrative regions of Zhuhai City, Jinwan District is playing an increasingly important role as a comprehensive transportation hub. In recent years, the economic development of Jinwan District has been rapid, especially the development of the secondary industry. Along with the growth of the economy, safety in production has also been attached more and more importance by the party and the country. With the continuous development of the theory and practice of emergency management, the concept of emergency management has gradually changed from “emergency after the event” to “prevention before the event”. The government and scholars pay more attention to the risk assessment and hidden danger screening in advance, so timely and effective risk assessment can not only reasonably judge hidden dangers, but also take necessary measures to eliminate risks in advance.

In this paper, the risk matrix method and Borda count method are used to assess the risk of production safety accidents in Jinwan district of Zhuhai city, and the corresponding governance strategies are proposed. The risk assessment of production safety accidents in the region in advance is conducive to the targeted investigation of hidden dangers and the early elimination of hidden risks. Accelerating the management and control of production safety risks is conducive to curbing the outbreak and spread of major risk accidents. It is of great significance to establish and improve the hidden danger control system to ensure the safety of people’s lives and property.

This paper analyzes the data of production safety accidents in Jinwan District of Zhuhai City in 2017. The method of risk matrix is used to divide the consequence criterion into four dimensions and the possibility criterion into five dimensions. In this paper, the principle of risk importance is determined according to the m-by-n risk matrix, and the risk level of production accidents is divided into three levels, including acceptable risk, tolerable risk and intolerable risk. Based on the actual situation of Jinwan District in Zhuhai, this paper adopts the influence scorecard to obtain the consequence value and possibility value, and determines the risk level of production safety accidents in Jinwan District according to the calculation results. Borda count method is adopted to rank the production safety accident risks in Jinwan District. Finally, combining with the actual situation of Jinwan District, this paper puts forward the corresponding risk management strategy.

2. Literature Review

From the perspective of public management, there are abundant articles on “production safety accidents”. Some scholars have conducted researches on “emergency plan”, “emergency material reserve”, “public opinion communication”, “accountability mechanism”, “accident investigation mechanism” and other aspects. At present, the article about “risk assessment of production safety accidents” mainly focuses on the study of single disaster. Zeng Liang (2008) [1] took the civil aviation insecurity events as the analysis object, took the four subsystems of human, aircraft, environment and management as the analysis framework, and adopted the Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE) to carry out risk assessment. Sun Aijun (2010) [2] established the causation analysis model of major production safety accidents from the perspective of social technology system, and made a case analysis of the Especially serious gas explosion accident in Tunlan coal mine of Shanxi Province. Compared with “single disaster bell”, the research results of “multi-disaster bell” are relatively few. Based on the accident cause theory, Li Weiquan (2016) [3] analyzes 150 production safety accidents from 2011 to 2015,and summarizes the 24 measures of risk factors,and six risk superposition factors.

ISO31000:2009 “risk management―principles and guidelines” defines “risk management” as “the coordinated activities of the command and control organization for risk”. ISO31000:2009 defines “risk assessment” as “the whole process of risk identification, risk analysis and risk assessment”. This definition indicates that the three sub-processes of risk assessment are indispensable and executed in sequence. The Electronic Systems Center (ESC) procurement engineering group first proposed the risk matrix method in April 1995. In the ISO guide73:2009 Risk management―terminology, Risk Matrix is defined by the international organization for standardization (ISO) as a tool for displaying and ranking risks by defining the range of consequences and possibilities. IEC 31010:2009 “risk management techniques” provides a total of 31 risk assessment methods and techniques, with serial number b.29, consequence/probability matrix, also known as “risk matrix”. In the process of project management, risk matrix is a structural method to identify the importance of project risk. It is a method that is easy to operate and combines qualitative analysis with quantitative analysis [4] . However, in the qualitative and semi-quantitative risk matrix, the risk level is very limited, resulting in the same or similar risk level of some risks. For the same or similar level of risk, it is necessary to determine which risk is more important and which risk can be put aside in the case of limited resources. The Borda count method can open the “risk knot” generated by the risk matrix and relatively accurately rank the importance of each risk.

At present, the risk matrix methods been applied in many fields such as health care, enterprise economy and public management, and it is often used in combination with Borda count method in the process of case analysis. Zhu Qichao [5] , Li Shuqing [6] and other scholars adopted Borda count method to improve the risk matrix method. Dong Yan (2010) [7] took social security incidents in some area of Beijing city for example, identified the risks of four types of disasters within the jurisdiction, determined the risk level based on the risk matrix method, and carried out risk ranking based on Borda count method. Zhang Hongxia (2013) [8] took 3300 food safety incidents in China as research samples, and adopted the risk matrix method to evaluate the risk factors in each link. In addition, some scholars combine the risk matrix method with Analytic Hierarchy Process (AHP). Xiong Jie (2010) [9] took the aerospace research project as the research object, used the Analytic Hierarchy Process (AHP) to construct the index system, obtained the relative weight of risk factors at all levels, and used the risk matrix method to carry out the single factor risk assessment. Liu Jin (2012) [10] used Borda count method and Analytic Hierarchy Process (AHP) to improve the risk matrix method in the risk assessment of hospital building fires.

In view of that above, the research achievement of “production safety accident” is abundant, but there is a relatively limited study of the risk assessment of the safety accident in a region. The overall assessment of the risks of various production safety accidents is conducive to the thorough investigation of hidden dangers in the jurisdiction, the timely detection of unsafe factors in the jurisdiction, and the targeted prevention measures for disasters with high risk levels. Based on the unique advantages of risk matrix method and Borda count method in risk assessment, this paper carries out risk assessment of production safety accidents in Jinwan district of Zhuhai city, and proposes corresponding risk management strategies.

3. Risk Assessment of Production Accidents in Jinwan District of Zhuhai City

Based on the classification of accidents and disasters in the National Emergency Plan for Public Emergencies, and in combination with the actual situation in Jinwan District of Zhuhai City, this paper constructed the risk factor index of production safety accidents in Jinwan District of Zhuhai City. Risk level is determined by analyzing consequence criterion (C criterion), possibility criterion (L criterion) and risk importance criterion. According to the risk matrix formula, the risk level of production safety accidents in Jinwan District of Zhuhai City is evaluated from the two aspects of occurrence probability and consequence degree. Borda sequence value method is used to rank the risk of production safety accidents in Jinwan District of Zhuhai City. The specific structure of the article is shown in Figure 1.

3.1. Production Accident Risk Factor Index Framework

This paper mainly evaluates the production safety accidents in Jinwan district of Zhuhai city, taking the production safety accidents as the first-level indexes. On the basis of the classification of accidents and disasters in the National Emergency Plan for Public Emergencies, combined with the actual situation learned from the investigation in Jinwan District of Zhuhai City, the Delphi method is adopted to adjust the individual indicators. In this paper, six kinds of indexes including industrial and mining accidents, fire accidents, transportation incident, public facilities and equipment accidents, radiation accidents, environmental pollution and ecological destruction events are taken as secondary indexes. On this basis, the relevant indicators are further divided into 20 three-level indexes. Industrial and mining accidents are divided into dangerous chemicals accidents,

mining accidents, construction accidents, fireworks accidents and special equipment accidents. Transportation incidents are divided into road traffic accidents, water traffic accidents, bus operation emergencies, railway traffic accidents and civil aircraft flight accidents. Public facilities and equipment accidents are divided into water supply emergencies, power emergencies, gas emergencies, highway and bridge emergencies, network and information security incidents, and civil air defense engineering accidents. Environmental pollution and ecological destruction events are divided into heavy pollution weather events and environmental emergencies.

3.2. Production Safety Accident Risk Assessment Grade System

Risk criteria are mainly used for risk assessment. In the ISO guide73:2009 risk management―terminology, “risk criteria” is defined as “a reference to evaluate the importance of risks”. The risk criterion involved in this paper includes consequence criterion (C criterion), possibility criterion (L criterion) and risk importance criterion.

3.2.1. Consequence Criterion (C Criterion)

Consequence criterion is mainly used to judge the severity of risk consequence. Pursuant to article 3 of Production Safety Accident Reporting and Investigation Regulations, according to the casualties or direct economic loss caused by the last year, the consequences of the accidents are divided into four grades, which are not serious, generally serious, respectively serious and very serious, and the corresponding scores are 1, 2, 3 and 4. The severity of risk consequences is shown in Table 1.

Table 1. Risk consequence severity judgment table.

Note: Meet the death toll or direct economic losses.

3.2.2. Possibility Criterion (L Criterion)

Possibility criterion is mainly used to judge the probability of risk occurrence. According to the number of the accidents in a certain period of time, the probabilities of the accidents are divided into five grades, which are very low frequency, relatively low frequency, generally high frequency and very high frequency, and the corresponding scores are 1, 2, 3, 4 and 5. The probability of risk occurrence is shown in Table 2.

3.2.3. Risk Importance Criterion

The risk importance criterion, also known as the “risk acceptance criterion”, refers to the standard to classify all risks according to their importance. This paper divides the risk importance criterion into three levels. The risk matrix is m by n matrix. “m” for the consequences, “n” for probabilities. As can be seen in Table 3 dark gray areas are called “high risk areas”, light gray areas are called “medium risk areas”, and white areas are called “low risk areas”.

3.2.4. Risk Level

In the ISO guide73:2009 risk management―terminology, “risk level” is defined as “the size or magnitude of a risk or combination of risks expressed as a combination of consequences and possibilities”. This paper divides the risk levels of production safety accidents into three levels, including acceptable risk, tolerable risk and intolerable risk. According to the calculation of the risk assessment matrix formula, the risk score within 1 - 3 is an acceptable risk, the risk score within 4 - 9 is a tolerable risk, and the risk score within 10 - 20 is an intolerable risk. The risk levels are shown in Table 4.

3.3. Risk Level of Production Safety Accident in Jinwan District of Zhuhai City

In the actual investigation of Jinwan District, the influence scorecard was used to obtain the consequence C value, and the possibility scorecard was used to obtain

the possibility L value. The specific score results are shown in Table 5. Special equipment accidents, railway traffic accidents, highway and bridge emergencies, civil air defense engineering accidents and radiation accidents are acceptable risks. Dangerous chemicals accidents, mining accidents, fireworks accidents, bus operation emergencies, civil aircraft flight accidents, water supply emergencies, power emergencies, gas emergencies and environmental emergencies are tolerable risks. Construction accidents, fire accidents, road traffic accidents, water traffic accidents, network and information security incidents and heavy pollution weather events are intolerable risks.

3.4. Borda Number of Production Safety Accident in Jinwan District of Zhuhai City

For the same or similar level of risk, Borda count method can effectively determine which risk is more important [11] . According to the calculation formula, this paper calculates the Borda number and Borda ordinal number of 20 third-level indexes respectively. The specific calculation results are shown in Table 6.

The Borda ordinal number of safety production risk in Jinwan District of Zhuhai City is ranked from low to high. The smaller Borda ordinal number is, the greater

Table 6. Borda number list of production safety accidents in Jinwan District of Zhuhai City.

the risk is. As can be seen in Table 6, the risk ranking results of production safety accident in Jinwan District of Zhuhai City are as follows: road traffic accidents, construction accidents, fire accidents, network and information security incidents, water traffic accidents, heavy pollution weather events, dangerous civil aircraft flight accidents, gas emergencies, fireworks accidents, water supply emergencies, railway traffic accidents, mining accidents, highway and bridge emergencies, radiation accidents, civil air defense engineering accidents and special equipment accidents.
