Description

Technical Field

[0001] This invention relates to the field of accident prevention and control technology, and more specifically, to an accident prevention and control system in enterprise safety consulting services. Background Technology

[0002] Accident prevention and control is the best way to reduce abnormal losses. Whether it is direct operators, managers or other related personnel, ensuring the safety of personnel at work is the primary responsibility of enterprises. Prevention and control can significantly reduce the occurrence of work-related accidents. Accidents can lead to damage to equipment, facilities and materials, and even cause serious consequences such as fires and explosions, resulting in huge property losses. Through prevention and control, losses can be effectively reduced and the safety of enterprise assets and property can be protected.

[0003] Accident prevention and control is difficult to monitor and evaluate in real time during actual production operations. In fact, it is extremely difficult to monitor any operation of all operators at the same time. Therefore, we can only use historical data and known information to build models and analyze them, and collect data in the safety consultation process to prevent and control potential accidents.

[0004] To address the aforementioned shortcomings, a technical solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an accident prevention and control system for enterprise safety consulting services, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an accident prevention and control system in enterprise safety consulting services, comprising a source extraction module, a standard specification module, a risk identification module, and an anticipatory control module;

[0007] The information source extraction module is used to collect engineering risk information and employee review information, and transmits the engineering risk information and employee review information to the standard specification module after preprocessing them.

[0008] The standards and specifications module is used to standardize and evaluate the operating procedures in the safety consulting process and to verify the differences between actual and standardized operations.

[0009] The risk identification module is used to assess the risks in security consulting services and to establish a risk assessment model to classify the degree of risk.

[0010] The expected control module is used to manage expected risk control based on risk level.

[0011] Preferably, the engineering risk information refers to the safety hazard elements of the work site obtained through the enterprise safety consulting service process, including physical risks, chemical risks and biological risks. Physical risks include working at height and mechanical equipment factors, chemical risks include hazardous chemicals, and biological risks include toxic gases. The employee verification information refers to the duration of safety risk training courses received by employees entering the work site.

[0012] The preferred method for risk assessment of risk points in security consulting services is as follows:

[0013] Let the calibrated height for high-altitude operations be Wh, the actual maintenance cycle of mechanical equipment be Mc, the saturated vapor concentration of hazardous chemicals at 0℃ be Sa, the predicted environmental concentration of toxic gases be Pe, the duration of safety risk training courses for employees be Ed, and the guiding probability from fault tree analysis and event tree analysis be Gp. Then, the expression for calculating the risk index Re in the risk assessment model is: In the formula, e is the number of the risk index oriented towards different accident outcomes, and e = { 1,2,3…Q } Nu represents the number of operating staff, and α and β are respectively... and The weighting coefficients are α and β, and both α and β are positive numbers.

[0014] Preferably, the logic for obtaining the guiding probability by combining fault tree analysis and event tree analysis is as follows:

[0015] By combining fault tree analysis and event tree analysis, the final accident outcome is determined. Guided by the accident outcome, a development path is constructed through preset initial events. The probability of the determined accident outcome is calculated using the minimum cut set method. The probability of the accident outcome resulting from the combination of fault tree analysis and event tree analysis is defined as the guiding probability.

[0016] The preferred method for comprehensive evaluation based on different accident outcomes is as follows:

[0017] A comprehensive assessment of risk indices oriented towards different accident outcomes is conducted to calculate the composite safety risk index Cr. The calculation method is as follows: In the formula, Q represents the total number of accident outcome types, Re represents the risk index, and e represents the number of the risk index oriented towards different accident outcomes, and e = { 1,2,3…Q } Cy represents the service cycle for security consulting.

[0018] Preferably, the logic for classifying the level of risk based on the risk assessment model is as follows:

[0019] A first risk threshold and a second risk threshold are preset, with the first risk threshold being less than the second risk threshold. When the calculated composite safety risk index is less than the first risk threshold, the safety level is classified as Level 1. When the calculated composite safety risk index is greater than or equal to the first risk threshold and less than or equal to the second risk threshold, the safety level is classified as Level 2. When the calculated composite safety risk index is greater than the second risk threshold, the safety risk level is classified as Level 3.

[0020] The preferred approach, based on different risk levels, is as follows:

[0021] If the safety risk level is Level 1, there is a risk of minor consequences, including minor personal injury and minor equipment damage. All minor risk events should be recorded and reported, and operating procedures should be optimized based on the analysis results of the records and reports.

[0022] If the safety risk level is level two, there is a risk of moderate consequences, including minor personal injury and equipment failure. Detailed emergency plans should be developed, an emergency response team should be established, and timely emergency rescue should be organized.

[0023] If the safety risk level is level three, there is a risk of serious consequences, including major personal injury, equipment damage, and environmental pollution. Real-time monitoring cameras are used to continuously monitor high-risk areas and operations, promptly detect and handle abnormal situations, and conduct regular risk audits and assessments.

[0024] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0025] This application visualizes the probability of risk events by combining fault tree analysis and event tree analysis. It establishes a risk assessment model for potential accident risks, evaluates and judges different types of accident risks, and conducts a comprehensive analysis by combining human and non-human factors in safe operating procedures. This can effectively solve potential risk problems in enterprise safety consulting services, effectively classify the risk level of different safety issues, reduce hidden crises in enterprise safety consulting, and improve the effectiveness of risk control.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1 As shown, the present invention is an accident prevention and control system in enterprise safety consulting services, including a source extraction module, a standard specification module, a risk identification module, and an anticipatory control module;

[0030] The information source extraction module is used to collect engineering risk information and employee review information, and transmits the engineering risk information and employee review information to the standard specification module after preprocessing them.

[0031] The standards and specifications module is used to standardize and evaluate the operating procedures in the safety consulting process and to verify the differences between actual and standardized operations.

[0032] The risk identification module is used to assess the risks in security consulting services and to establish a risk assessment model to classify the degree of risk.

[0033] The expected control module is used to manage expected risk control based on risk level.

[0034] In corporate safety consulting services, accident prevention and control are crucial. Preventive management can effectively reduce workplace accidents, protect employee lives and health, and improve employee safety and job satisfaction. Engineering testing work often involves complex equipment, high-altitude operations, and chemical handling—high-risk operations in particular. Effective accident prevention and control can reduce work-related injuries and occupational diseases, ensuring employee health and safety. Accidents often lead to direct economic losses, such as medical expenses, compensation costs, and production stoppages. Preventive management can reduce these unnecessary expenses, protecting the company's economic interests. A safe working environment reduces downtime and production interruptions caused by accidents, ensuring the continuity and stability of testing work, thereby improving overall work efficiency and productivity. Accidents often bring direct and indirect economic losses, including medical expenses, compensation costs, equipment repair costs, and economic losses due to production delays. Effective preventive control measures can significantly reduce these economic losses. A safe working environment helps improve employee work efficiency, reduces downtime and equipment damage caused by accidents, thereby improving the company's production efficiency and capacity. Furthermore, effective safety management and a low accident rate can allow companies to obtain lower insurance premiums, saving operating costs. Various regions have strict legal and regulatory requirements for workplace safety. Implementing accident prevention management helps companies comply with regulations and avoid legal sanctions and fines for violations. A company's safety record affects its public image and market competitiveness. Good accident prevention management can enhance a company's social responsibility and reputation, strengthen customer and partner trust, further expand market opportunities, and a safety-conscious corporate culture can boost employee morale, enhance team cohesion, reduce employee turnover, and attract and retain top talent. Safety is the cornerstone of a company's long-term development. Through systematic accident prevention management, companies can establish a scientific safety management system to support their long-term healthy and sustainable development.

[0035] In enterprise safety consulting services, the information source extraction module of the accident prevention and control system is used to collect engineering risk information and employee review information, and transmits the engineering risk information and employee review information to the standard specification module after preprocessing them.

[0036] Engineering risk information consists of safety hazard elements at the work site obtained through the enterprise safety consulting service process. These include physical risks, chemical risks, and biological risks. Physical risks include working at heights and mechanical equipment factors, chemical risks include hazardous chemicals, and biological risks include toxic gases. By analyzing historical safety risk data and existing accident and hazard records, risk sources are extracted and identified. The risk level is then assessed using fault tree analysis and event tree analysis.

[0037] Fault tree analysis is a top-down deductive analysis method that identifies potential risk sources and critical failure paths in a system by analyzing various basic events that may lead to a specific top event.

[0038] It should be noted that the top event is a system failure or accident, while basic events include component failure or operational error.

[0039] The analysis process involves determining the top event to be analyzed, starting from the top event, decomposing layer by layer, identifying the direct and indirect causes of the top event, using logic gates to connect the basic events to form a tree structure, determining the contribution of each basic event to the top event through qualitative or quantitative analysis, and identifying the basic events and paths that have the greatest impact on the top event.

[0040] Logic gates, such as AND gates and OR gates, are commonly used in quantitative analysis methods, including minimal cut sets and fault probability calculation.

[0041] The employee verification information refers to the duration of safety risk training courses received by employees entering the work site. Safety risk training enables employees to identify potential risks in their work, take preventative measures, and reduce the occurrence of accidents. If employees understand correct operating procedures and protective measures, the occurrence of work-related injuries and occupational diseases can be effectively reduced. Simultaneously, accident prevention can avoid production interruptions caused by accidents, ensuring the continuity and stability of the production process. After mastering safe operating skills, employees can improve work efficiency and quality, and reduce production delays, customer loss, and reputational damage caused by accidents. Through training, employees understand emergency plans and emergency response procedures, improving their emergency response capabilities in the event of emergencies and reducing the impact of accidents. The duration of safety risk training courses is directly related to the level of operational safety risk; the more comprehensive the understanding of safety risks, the lower the probability of non-standard operations, and the higher the level of safety.

[0042] The standards and specifications module is used to standardize and evaluate the operating procedures in the safety consulting process and to verify the differences between actual and standardized operations.

[0043] Check whether the company has developed complete operating procedures, including all testing and operation steps, ensuring that each step has detailed guidance documents, confirming whether the company has established a systematic and standardized document system covering operating procedures, maintenance procedures, safety manuals, etc., assessing the consistency between actual operation and standard procedures, ensuring that all employees strictly follow standardized procedures when performing operations, regularly evaluating the implementation of procedures through internal audits and third-party inspections, identifying and correcting deviations, measuring what percentage of employees have received training on operating procedures and standardized procedures, including new employee training and regular training for existing employees, evaluating the training effectiveness through examinations, practical exercises, etc., to ensure that employees master and can correctly execute standardized operating procedures;

[0044] In actual operation, check the record and traceability system of the operation process to ensure that each operation step is recorded in detail and can be traced back to the specific personnel and operation time. Identify and monitor key operation links and control points to ensure that key links are strictly executed in accordance with standardized procedures. Assess whether the operation procedures include the identification and assessment of potential risks to ensure that all operation steps take into account possible safety risks. Check the implementation of risk control measures to ensure that each risk control point is effectively managed and monitored.

[0045] The risk identification module is used to assess the risks in security consulting services and to establish a risk assessment model to classify the degree of risk.

[0046] The method for constructing a risk assessment model is as follows:

[0047] Let the calibrated height for high-altitude operations be Wh, the actual maintenance cycle of mechanical equipment be Mc, the saturated vapor concentration of hazardous chemicals at 0℃ be Sa, the predicted environmental concentration of toxic gases be Pe, the duration of safety risk training courses for employees be Ed, and the guiding probability from fault tree analysis and event tree analysis be Gp. Then, the expression for calculating the risk index Re in the risk assessment model is: In the formula, e is the number of the risk index oriented towards different accident outcomes, and e = { 1,2,3…Q } Nu represents the number of operating staff, and α and β are respectively... and The weighting coefficients are α and β, and both α and β are positive numbers.

[0048] It should be noted that predicted environmental concentration refers to the concentration of a chemical substance in a specific environmental medium, such as water, soil, or air, predicted by a model during the environmental risk assessment process, based on factors such as the release characteristics, usage patterns, and environmental behavior of the chemical substance. Methods for obtaining predicted environmental concentration include mathematical models or actual environmental measurements. Mathematical model calculations use mathematical equations to describe the behavior of chemical substances in the environment, including processes such as diffusion, adsorption, and degradation. Actual environmental measurements directly use measured concentrations from environmental monitoring data.

[0049] A comprehensive assessment of risk indices oriented towards different accident outcomes is conducted to calculate the composite safety risk index Cr. The calculation method is as follows: In the formula, Q represents the total number of accident outcome types, Re represents the risk index, and e represents the number of the risk index oriented towards different accident outcomes, and e = { 1,2,3…Q }Cy represents the safety consulting service cycle. A first risk threshold and a second risk threshold are preset, with the first risk threshold being less than the second risk threshold. When the calculated composite safety risk index is less than the first risk threshold, the safety level is classified as Level 1. When the calculated composite safety risk index is greater than or equal to the first risk threshold and less than or equal to the second risk threshold, the safety level is classified as Level 2. When the calculated composite safety risk index is greater than the second risk threshold, the safety risk level is classified as Level 3.

[0050] The expected control module is used to manage expected risk control based on risk levels;

[0051] If the safety risk level is Level 1, there is a risk of minor consequences, including minor personal injury and minor equipment damage. All minor risk events should be recorded and reported, and operating procedures should be optimized based on the analysis results of the records and reports.

[0052] If the safety risk level is level two, there is a risk of moderate consequences, including minor personal injury and equipment failure. Detailed emergency plans should be developed, an emergency response team should be established, and timely emergency rescue should be organized.

[0053] If the safety risk level is level three, there is a risk of serious consequences, including major personal injury, equipment damage, and environmental pollution. Real-time monitoring cameras are used to continuously monitor high-risk areas and operations, promptly detect and handle abnormal situations, and conduct regular risk audits and assessments.

[0054] Example 2: In a specific example, fault tree analysis is used to assess the risk state, with a serious personal injury occurring during the safety inspection process as the top event. Logic gates are used to connect the top event with each basic event, and the logical relationship is as follows:

[0055] A1 high-altitude fall

[0056] B1 lacks safety protection equipment (AND door).

[0057] C1 Not wearing a seatbelt

[0058] C2 has no guardrails.

[0059] B2 Protective Equipment Failure (AND Door)

[0060] C3 Seat belt is old or damaged

[0061] C4 Guardrail is loose or damaged.

[0062] A2 electric shock accident

[0063] B3 Equipment Leakage (AND Gate)

[0064] Improper maintenance of C5 equipment

[0065] C6 insulation material aging

[0066] B4 was not operated according to specifications (AND gate)

[0067] C7 operator failed to operate according to specifications.

[0068] C8 lacks operational training

[0069] A3 chemical leak

[0070] Improper storage of chemicals (AND gate)

[0071] C9 storage container damaged

[0072] C10 chemical storage environment was not compliant.

[0073] B6 Operational Error (AND Gate)

[0074] C11 Operator Misoperation

[0075] C12 was not wearing protective equipment.

[0076] A4 Mechanical Damage

[0077] B7 Equipment Failure (AND Gate)

[0078] C13 equipment aging

[0079] C14 maintenance not in a timely manner

[0080] B8 equipment malfunction (AND gate)

[0081] C15 operator is not proficient

[0082] C16 lacks operating procedures.

[0083] Qualitative and quantitative analyses are performed on each basic event to assess its probability of occurrence and its contribution to the top event. Qualitative analysis identifies the critical path in each branch and determines the main risk sources and weak links. Quantitative analysis assigns a probability value to each basic event, calculates the overall probability of each branch, and determines the overall risk level of the top event.

[0084] Use the minimum cut set method to find the minimum set of events that leads to the top event, and calculate the probability of the occurrence of the minimum set of events.

[0085] Event tree analysis is a bottom-up inductive analysis method that assesses the potential risks and consequences of a system by analyzing the possible development paths and consequences after an initial event occurs. The process of event tree analysis is as follows:

[0086] The initial event for analysis is determined. The initial event is usually a system failure or external event with failure potential. Starting from the initial event, the possible subsequent events and system responses are analyzed step by step. Each branch represents a possible path or event development process. The probability of occurrence of each branch is assigned, the probability of occurrence of each final event is calculated, the consequences and impact of each final event are evaluated, and the most likely and most serious accident path is determined.

[0087] By combining fault tree analysis and event tree analysis, the final accident outcome is determined. Guided by the accident outcome, a development path is constructed through preset initial events. The probability of the determined accident outcome is calculated using the minimum cut set method. The probability of the accident outcome resulting from the combination of fault tree analysis and event tree analysis is defined as the guiding probability.

[0088] This application visualizes the probability of risk events by combining fault tree analysis and event tree analysis. It establishes a risk assessment model for potential accident risks, evaluates and judges different types of accident risks, and conducts a comprehensive analysis by combining human and non-human factors in safe operating procedures. This can effectively solve potential risk problems in enterprise safety consulting services, effectively classify the risk level of different safety issues, reduce hidden crises in enterprise safety consulting, and improve the effectiveness of risk control.
